cacti-user Mailing List for Cacti

Hi all!

Just a question: 
What is the intention of '/usr/bin/smbstatus | grep -c ' as the input
string for the above mentioned Data Input?

grep -c just prints out it's help. 
I think it should read like '/usr/bin/smbstatus -L | wc -l' or sth like
that.

Hi all,

I am trying to display available disks space on a drive on an NT server
using snmp.  Data sources looks ok, cron printout with output is ok. 

The graph source: 

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start="-86400" \
--title="Exchange Disks Space Available on C:" \
--rigid \
--base=1000 \
--height=150 \
--width=500 \
--alt-autoscale-max \
--vertical-label="In megabytes (meg)" \
DEF:a="/home/httpd/htdocs/cacti/rra/exchange-diskavail.rrd":disk-1:AVERAGE \
AREA:a#0000FF:"Available space\: 907 megs" 


The legend is showing the 907 megs but nothing shows up on the graph.  

Any ideas?

Thanks in advance.

Yep, I think the RRDs are fine. 
But, well, when I update the RRD manually with, say, 
-- snip --
/usr/bin/rrdtool update /usr/share/cacti/rra/traf_moria_isdn_in.rrd --template traf_moria_isdn_in N:371457499
-- snap --

I think there should be at least some number (e.g. 371457499) in the output of 
-- snip --
rrdtool fetch traf_moria_isdn_in.rrd MAX
-- snap --
or not? But then there are just nan's...

Yep, the octets field is the only one updated. I think the fault is not
with the 'Get SNMP Network Data' Input, because other Network-graphs are
showing up fine.

Here too, everything looks alright, except that when I click on 'edit
data' for one of the not-working data sources, he says: 
-- snip --
INTERNAL: [moria/wolken] Interface: [5]
/usr/bin/rrdtool update /usr/share/cacti/rra/traf_moria_isdn_in.rrd --template traf_moria_isdn_in:traf_moria_isdn_in N:0.28:371445015
-- snap --
The only fields that are used for the Data Source Configuration are
'In/Out Data' (in), 'Interface Number' (5), 'IP Address' (moria) and
'SNMP Community' (wolken).

When I click on save, nothing changes...

Hm, doesnt look good...

Without a doubt, that is very weird. It appears as if your RRD files are
just fine (going by the create statements). However for some reason
cacti is getting confused when generating the 'update' statement.

Assuming you created these graphs using the 'Make Graph' feature, go
into 'Data Input' and select 'Get SNMP Network Data'. Make sure 'Update
RRA' is selected only for the octets field.

You may also want to double check that the 'Get SNMP Network Data'
script is selected for the offending data sources, make sure to click
'save' when you are done. In addition to that, select 'edit data' next
to those data sources and make sure the data all looks correct. Then
click save, forcing cacti to re-write all of that data. I am hoping that
something got messed up when the data sources were created and "saving"
them will fix it.

Either way, tell me how it goes.

I am assuming that executing this script from the command line (perl
finger.pl @core) returns the correct response? That is it should just be
returning a number and nothing else.

Second, you'll want to make sure your data input source is setup
correctly. Going by what you've said, your input string should look
something like:

perl <path_cacti>/scripts/finger.pl <ip>

Then assuming your script just outputs the number of users, your output
string should look something like:

<users>

Lastly, you must then define both of these field names under "Current
Data Input Source Fields". Make sure the 'data name' is exactly the same
as the name used in the input/output strings (without the <>'s). Also
make sure you select 'Update RRA' when adding the 'users' output field.

Let me know if that does not help.

I defined a data source input for a snmp wrapper script I wrote.
I added a "host" field, but I realize there is a kind of internal
variable collision, and the thing doesn=B4t work properly. As I rename
it to "ip", as it is used in other scripts, it started to work.

Is it a bug? A feature?

Hi all! Sorry for being a lame newbie, I'm just trying to get all this
things right... 

I'm having a small problem with the snmp-network-data-gathering. I've
got a few hosts cacti monitors, each with 2 or more NICs. When I told
cacti about the host/community combination, it was happy to generate me
some graphs, and most of them are working like they should. 
Like this one (I'll just post all the commands cacti executes):

rrd created:
-- snip --
/usr/bin/rrdtool create \
/usr/share/cacti/rra/traf_deepthought_eth0_in.rrd \

-- snip --

GPRINT:b:LAST:"Current\:%8.2lf %s" \
GPRINT:b:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:b:MAX:"Maximum\:%8.2lf %s" 
-- snap --

As I said, this graph looks allright. But then I wanted to monitor
another NIC, an ISDN Uplink to the world:

rrd created (with snmp-network-data...):
-- snip --
/usr/bin/rrdtool create \
/usr/share/cacti/rra/traf_moria_isdn_in.rrd \

RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 
-- snap --
(yep, it's another computer, but the other two nics are showing up nicely)

rrd updated:
-- snip --
/usr/bin/rrdtool update /usr/share/cacti/rra/traf_moria_isdn_in.rrd \
--template traf_moria_isdn_in:traf_moria_isdn_in N:0.28:367072606
-- snap --


The one strange thing I notice here is that for eth0 in deepthought the
template is called "traf_deepthought_et" but for ippp3 in moria the
template is called "traf_moria_isdn_in:traf_moria_isdn_in". The other
thing is that for ippp3 in moria cacti says 'update now 0.28:367072606',
and for deepthought he says 'update now 1613170999'.
I don't understand this, can somebody explain this to me?

When I do a 'rrdtool fetch traf_moria_isdn_in.rrd MAX', I just get tons
of NANs.

(Graph created command skipped, cause it makes no sens when all data is
NAN)

I also have a similar (or the same?) problem, when I try to monitor the
disk usage of one partition: 

-- snip --
/usr/bin/rrdtool update /usr/share/cacti/rra/nathan_data.rrd --template
nathan_data:nathan_data N:0.03:5017584
-- snap --

isn't working, but

-- snip --
/usr/bin/rrdtool update /usr/share/cacti/rra/nathan_root.rrd --template
nathan_root N:629897
-- snap --

is.

Did I do something wrong when I (or cacti) made the rrd's?

Lukas Kolbe <lu...@kn...>

I'm very new to cacti, and I'm trying to get cacti to do something
it doesn't do out of the box (at least not supplied with), something
very important to us as an ISP.

I need it to be able to do a finger of several boxes.
for example: finger @core | grep PPP | wc -l
will show the number of users logged into the core box at any time.

I wrote my own finger.pl script in cacti/scripts directory, believe me,
writing it was a nightmare!  I first tried to take the number of users script
and the ping scripts and somehow combine them, that was a total wash,
even changing either of the ping scripts didn't work either. But I finally got
it so if I run my finger.pl @core it will return a # of users, I got it to 
work by
using ping-new.pl and changing most of it.

the problem is, this script doesn't work. when I try to run php cmd.php
I get a weird error response. It sees the returned # of users as what looks
like it's expecting an SNMP response, something like:
error: 44:.....

where the "44" is actually the # of users from the box. very strange.

I have no idea why it does this, since when I run it from command line, it
works fine.

I have about 20 boxes I need to do this with, so I assumed I could go into
data input and data sources and use finger.pl that I wrote with passing it
an "ip" (which would actually be passed as "@core", etc in the data edit
for the graph). The "@" is critical, otherwise it just isn't useful at all,
and maybe that's what the script is having problems with - but I even wrote
a special finger-core.pl which had the @core within the script and I got 
the same
strange errors when running php cmd.php

If anyone wants to see the script I actually wrote and the actual respose, 
I can
send that, but I figured I'd ask first, because it's probably something stupid.

Thanks

Dan.

Don't worry it will get changed. Anything I can do to prevent
unnecessary config file changes is a plus in my mind.

Hi all! I'm actually very new to Cacti and this list (having a problem

fix Cacti not to use short open tags? Then Cacti .php could be made

It's just a suggestion, not a 'my style is better than yous' flame or

However, keep on that good work!

Hi!

Do not showing up in graph WAN LINKS
Some idea of like doing it

Att. Oscar Rojas


    Actually this looks like a valid graph command. With the necessary data,
    it should render a valid graph. If the graph instead appears as a broken
    image, then this graph command is in fact at fault.
    
    Otherwise, I would be checking to make sure cacti is getting the load
    average data correctly. To check this, I recommend tailing cacti's log
    file at 'log/rrd.log' while cmd.php is running. You should see a line
    that goes something like:
    
    /usr/bin/rrdtool update firewall_system_loa.rrd --template
    1min:10min:5min N:0.01:0.22:0.05
    
    If instead of the load average you see U's (N:U:U:U), then cacti is not
    getting the data it expected from the script.

Hi Ian,

Found the problem: when my script returns the values, there is a cariage
return with the "10 min" value. It is cause by the print command.  I created
a python script that output the value with sys.stdout.write() function and
it is now working fine.

Actually this looks like a valid graph command. With the necessary data,
it should render a valid graph. If the graph instead appears as a broken

Otherwise, I would be checking to make sure cacti is getting the load
average data correctly. To check this, I recommend tailing cacti's log
file at 'log/rrd.log' while cmd.php is running. You should see a line
that goes something like:

/usr/bin/rrdtool update firewall_system_loa.rrd --template
1min:10min:5min N:0.01:0.22:0.05

If instead of the load average you see U's (N:U:U:U), then cacti is not
getting the data it expected from the script.

Dear All,

Thanks for the quick reply.
I have followed the steps to set up a new datasource.
After completing it, the graph is made but empty :-(.
When I look at the cron print out it shows nothing..??
INTERNAL: [10.100.57.252/snmp-string] OID: [.1.3.6.1.4.1.9.2.1.58.0]
INTERNAL: [10.4.128.129/snmp-string] OID: [.1.3.6.1.4.1.9.2.1.56.0]

Also when I manualy start cmd.php I do not get any strange output...


Any ideas??

Lucas Deneken

I don't know that I'd consider Cacti easier than MRTG.  Cacti makes a ver=
y
tedious thing with a steep learning curve easier by providing a gui
interface, but the thing it makes easier is RRDTool, not MRTG.  By far th=
e
thing that made Cacti easier for me to finally grasp was realizing that m=
ost
of the questions you have are probably not Cacti questions but rather
RRDTool questions.

For example, if you start out using Cacti without digging into rrdtool by
hand, you're probably wondering things like:
    - What's a CDEF?
    - What's a GPRINT, AREA, STACK, LINE2, etc?
    - What's a datasource?
    - When do I want to "update the rrd"?

All of those questions are easier to figure out if you get some backgroun=
d
with rrdtool first.  Highly recommend the rrdtool tutorials and the rrdgr=
aph
manual page:
http://www.rrdtool.com//tutorial/ <http://www.rrdtool.com//tutorial/>
http://www.rrdtool.com//manual/rrdgraph.html
<http://www.rrdtool.com//manual/rrdgraph.html>

The general sequence of events in creating a graph with cacti is:
- Log in as an administrator.
- Click the console tab.
- Click on Data Sources.
- Click on Add.
    - Give the data source a name: myrouter_5min_cpu
    - Assuming you're using SNMP to poll the router, Data Input Type is "=
Get
SNMP data".
    - For cpu, the type is usually GUAGE.
    - Select the RRA's you want - probably all of them.
    - Enable the "Update changes in rrd file" checkbox.
- Click Save.
- Back in the Current Data Sources page, find your new data source and cl=
ick
on "Edit data".
    - Enter the hostname/ip address, the snmp community, and the SNMP oid
you want to pull.  Tip: The oid should start with a period - that caused =
me
so many headaches. :-(
    - Click Save.
- Back in the console page, click "Graphs".  Then either add your new dat=
a
source to an existing graph or click Add.
    - Stuff in the Add Graph window is probably self explanatory - if not=
,
ask questions, I'll try to help.
    - Save the graph.
- Back in the console again, click "Graph Heirarchy", then click on "Edit
graph heirarchy" next to "Default tree" (or whatever tree you want to add
the graph to).
    - Click the Add button next to the parent of the brancy you want to a=
dd
your new graph to.
        - Select "This item is a graph", then choose your graph from the
drop-down menu and the RRA you want to show up (doesn't matter which one).

Then go look at your graphs tab and see if you can find the new graph.

Doing this mostly from memory, so I may have missed something - ask for h=
elp
if you need it.

Subject: [cacti-user] Problem, data not showing up in graph...
Reply-To: cac...@li...

Hi all,

I am trying to get remote load average, but can't get the data to show up.

Looks like my problem is in the data source, this is what I get:

/usr/bin/rrdtool graph - \
--imgformat=3DPNG \
--start=3D"-86400" \
--title=3D"Firewall Load_Average" \
--rigid \
--base=3D1000 \
--height=3D150 \
--width=3D500 \
--alt-autoscale-max \
--units-exponent=3D1 \
--vertical-label=3D"Average Load" \
DEF:a=3D"/home/httpd/htdocs/cacti/rra/firewall_system_loa.rrd":1min:AVERA=
GE \
DEF:b=3D"/home/httpd/htdocs/cacti/rra/firewall_system_loa.rrd":10min:AVER=
AGE \
DEF:c=3D"/home/httpd/htdocs/cacti/rra/firewall_system_loa.rrd":5min:AVERA=
GE \
CDEF:cdefd=3Da,b,c,+,+ \
AREA:b#EACC00:"10 Minute\: 0.01
\n" \
STACK:c#EA8F00:"5 Minute\: 0.03\n" \
STACK:a#FF0000:"1 Minute\: 0.00\n" \
LINE1:cdefd#000000:"Total"

Notice the line starting AREA gets chopped, and I don't know why...

Here is the script I use to get the data, a modified version of Danny
Bendersky's script:

#!/bin/sh
#
# snmp-cacti-load.sh
#
# Verify that there is an input
# ------------------------------
if [ -z "$1" ]; then
echo "usage: snmp-cacti-load.sh <server> <snmp-comunity> <num>"
echo
exit
fi
#
# Variables
# ---------
SERVER=3D$1                    # Example: 10.0.0.3
SNMPCOMUNITY=3D$2              # Example: public
NUM=3D$3                       # Example: 1
#

|awk '{print $3}'`
echo $LOAD1 $LOAD5 $LOAD15

Thanks in advance,

End of cacti-user Digest

Actually this looks like a valid graph command. With the necessary data,
it should render a valid graph. If the graph instead appears as a broken
image, then this graph command is in fact at fault.

Otherwise, I would be checking to make sure cacti is getting the load
average data correctly. To check this, I recommend tailing cacti's log
file at 'log/rrd.log' while cmd.php is running. You should see a line
that goes something like:

/usr/bin/rrdtool update firewall_system_loa.rrd --template
1min:10min:5min N:0.01:0.22:0.05

If instead of the load average you see U's (N:U:U:U), then cacti is not
getting the data it expected from the script.

Yeah I fixed it with that and with the php-mysql rpm that someone posted
on the forums.
scary stuff

it actually works now

In "php.ini", you need the following setting:

   short_open_tag = On

It doesn't say this in the installation doc though (not last time I
checked, at-least).

Don't forget to drop-kick the webserver after making the change.  I'm
not sure if it's strictly necessary with a mod, but it can't hurt.

Later,
Paul.

This was previously mentioned as a problem:

Through some fumbling about - I'm a programmer, not a PHP programmer - I fo=
und that converting the <?...?> sequences to <?php ... ?> (with spaces) fix=
ed it.  I used something like this to do it:

for i in $(find . -name "*.php") ; do \
   sed 's/<?/&php /g; /?>/ &/g;' < $i >$i.out ; \
   mv $i $i.orig ; \
   mv $i.out $i ; \
done

Don't miss the spaces in the replacement strings; they seemed to be importa=
nt.

When loading the index.php page I get this:

raXnet cacti (about)"); DrawMatrixRowEnd(); DrawMatrixTableEnd(); 
include_once ("include/bottom_footer.php"); ?>

however other php pages work (about, etc)

I have no idea what this means

As for the specifics you requested regarding Cisco CPU & Memory, here 
is what has worked for me with my Switches & Routers:

•	Free Processor Memory:	  .1.3.6.1.4.1.9.9.48.1.1.1.6.1
•	Used Processor Memory:	  .1.3.6.1.4.1.9.9.48.1.1.1.5.1
•	Free I/O Memory:	  .1.3.6.1.4.1.9.9.48.1.1.1.6.2
•	Used I/O Memory:	  .1.3.6.1.4.1.9.9.48.1.1.1.5.2
•	5 Second CPU Utilization: .1.3.6.1.4.1.9.2.1.56.0
•	1 Minute CPU Utilization: .1.3.6.1.4.1.9.2.1.57.0
•	5 Minute CPU Utilization: .1.3.6.1.4.1.9.2.1.58.0
Create an "Get SNMP Data" Data Source
Use the appropriate OIDs above with the IP address and community name 
of the device you want to monitor.  Then use the Data Source(s) in your 
graph(s).

Hi all,

I am trying to get remote load average, but can't get the data to show up. 

Looks like my problem is in the data source, this is what I get: 

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start="-86400" \
--title="Firewall Load_Average" \
--rigid \
--base=1000 \
--height=150 \
--width=500 \
--alt-autoscale-max \
--units-exponent=1 \
--vertical-label="Average Load" \
DEF:a="/home/httpd/htdocs/cacti/rra/firewall_system_loa.rrd":1min:AVERAGE \
DEF:b="/home/httpd/htdocs/cacti/rra/firewall_system_loa.rrd":10min:AVERAGE \
DEF:c="/home/httpd/htdocs/cacti/rra/firewall_system_loa.rrd":5min:AVERAGE \
CDEF:cdefd=a,b,c,+,+ \
AREA:b#EACC00:"10 Minute\: 0.01
\n" \
STACK:c#EA8F00:"5 Minute\: 0.03\n" \
STACK:a#FF0000:"1 Minute\: 0.00\n" \
LINE1:cdefd#000000:"Total" 

Notice the line starting AREA gets chopped, and I don't know why...

Here is the script I use to get the data, a modified version of Danny
Bendersky's script: 

#!/bin/sh
#
# snmp-cacti-load.sh
#
# Verify that there is an input
# ------------------------------
if [ -z "$1" ]; then
echo "usage: snmp-cacti-load.sh <server> <snmp-comunity> <num>"
echo
exit
fi
#
# Variables
# ---------
SERVER=$1                    # Example: 10.0.0.3
SNMPCOMUNITY=$2              # Example: public
NUM=$3                       # Example: 1
#
LOAD1=`/usr/bin/snmpget $SERVER $SNMPCOMUNITY .1.3.6.1.4.1.2021.10.1.3.1
|awk '{print $3}'`
LOAD5=`/usr/bin/snmpget $SERVER $SNMPCOMUNITY .1.3.6.1.4.1.2021.10.1.3.2
|awk '{print $3}'`
LOAD15=`/usr/bin/snmpget $SERVER $SNMPCOMUNITY .1.3.6.1.4.1.2021.10.1.3.3
|awk '{print $3}'`
echo $LOAD1 $LOAD5 $LOAD15 

Thanks in advance,

I don't know that I'd consider Cacti easier than MRTG.  Cacti makes a very
tedious thing with a steep learning curve easier by providing a gui
interface, but the thing it makes easier is RRDTool, not MRTG.  By far the
thing that made Cacti easier for me to finally grasp was realizing that most
of the questions you have are probably not Cacti questions but rather
RRDTool questions.
 
For example, if you start out using Cacti without digging into rrdtool by
hand, you're probably wondering things like:
    - What's a CDEF?
    - What's a GPRINT, AREA, STACK, LINE2, etc?
    - What's a datasource?
    - When do I want to "update the rrd"?
 
All of those questions are easier to figure out if you get some background
with rrdtool first.  Highly recommend the rrdtool tutorials and the rrdgraph
manual page:
http://www.rrdtool.com//tutorial/ <http://www.rrdtool.com//tutorial/> 
http://www.rrdtool.com//manual/rrdgraph.html
<http://www.rrdtool.com//manual/rrdgraph.html> 
 
The general sequence of events in creating a graph with cacti is:
- Log in as an administrator.
- Click the console tab.
- Click on Data Sources.
- Click on Add.
    - Give the data source a name: myrouter_5min_cpu
    - Assuming you're using SNMP to poll the router, Data Input Type is "Get
SNMP data".
    - For cpu, the type is usually GUAGE.
    - Select the RRA's you want - probably all of them.
    - Enable the "Update changes in rrd file" checkbox.
- Click Save.
- Back in the Current Data Sources page, find your new data source and click
on "Edit data".
    - Enter the hostname/ip address, the snmp community, and the SNMP oid
you want to pull.  Tip: The oid should start with a period - that caused me
so many headaches. :-(
    - Click Save.
- Back in the console page, click "Graphs".  Then either add your new data
source to an existing graph or click Add.
    - Stuff in the Add Graph window is probably self explanatory - if not,
ask questions, I'll try to help.
    - Save the graph.
- Back in the console again, click "Graph Heirarchy", then click on "Edit
graph heirarchy" next to "Default tree" (or whatever tree you want to add
the graph to).
    - Click the Add button next to the parent of the brancy you want to add
your new graph to.
        - Select "This item is a graph", then choose your graph from the
drop-down menu and the RRA you want to show up (doesn't matter which one).
 
Then go look at your graphs tab and see if you can find the new graph.
 
Doing this mostly from memory, so I may have missed something - ask for help
if you need it.

Subject: [cacti-user] New to Cacti


Dear all,
 
I am new to Cacti. My former colleuge was wrking with MRTG, but when he left
he did not leave any documantion on how he did set it up. Now I am supposed
to get a new system up and running. After installing Cacti on a Debian
GNU/Linux 2.2 machine the standard traffic is working fine.
But when I want to get CPU/MEMORY and PING results of Cisco equipment I am
running in to some difficulties. I am working now for about 4 weeks on this
problem. 
Can some one help be by sending "step-by-step" information on how to add a
new Data source for this.
On the website of cacti I also looked into the source of some graphs, but
did not figured out..
 
Please help
 
Thanks in advance..

Hi,

I have cacti up and running, I would like to have the same graph "Load
average" for other server on the lan. I have installed ucd-snmp on these
servers, but can't find the load values (1-5-10 minutes).  

Can someone help???

Thanks in advance,
