cacti-user Mailing List for Cacti

Hello

I change update time of rrd databases to 1 minute,
modify crontab entry, and daily rra.
Now i setup monitoring for mail subsystem. I have 1-minutes graph for 
messages's rate, but i can't understand how can i make per 5 minutes graph...
for example, i have ~5 messages per minute, so i want to see values about 25 
at my per 5-minutes graph
Could anybody help with this?

Finally found some good docs, and I've got some basic SNMP down, so 
where I've been able to make some graphs.  Found this, looks as if 
someone isn't respecting the copyrights, but it helped.  If the Oreilly 
SNMP book is like this, its a definate pickup for me.

http://www.unix.org.ua/orelly/perl/sysadmin/appe_01.htm

I'm trying to tackle the traffic graphs before I move onto my own data 
collection/graphing.  But what are the following, they are in the:     
Template: Interface - Traffic (bytes/sec, Total Bandwidth)]

Custom Data

Index Type
Index Value
Output Type ID

This has got me stumped.  Didn't see anything in the docs, though it 
does talk about these fields in other areas (not graph template), and in 
those areas it says to leave them blank.  Leaving blank, it does not save.

Howdy!

In using cacti over the past week or two, I've noticed an annoying bug
when editing graph template item:  Specifically, when editing a graph
template with more than one data souce of the same type (ie. same
task_item_id), subsequent edits to graph template items always resets
them to be associated with the last added data source of the appropriate
type.

For example:  Suppose I have two hosts for which I'd like to graph their
traffic_in interface data on the same graph.  If I add hostA's data
source first, then hostB's data source second, then go back and edit a
graph template item that refers to hostA's data source, when I save the
graph template item its association will be switched to hostB's data
source.

The following patch (which I'll also include as an attachment in case my
company's crappy mail software mangles it) corrects this problem:  When
editing a graph template item, if you don't change the data source type
(task_item_id), then its association with a data source won't be changed
if one already exists.

hi,


i wonder if it is possible to have a distibuted environnement for cacti, i 
mean remote poller and a central database/webserver for consolidation.

thanks in advance.

Hi,


I was wondering if there is any way to have cacti in other language than 
english.
We want to use it in my company but none of then are speaking english, 
so it'll be a little difficult.
Is there any project to translate cacti in other language, because if 
none I'm ready to do a french version.

I found few message in "include/config_arrays.php", but before starting 
everything, I want to be sure that
nothing have been done yet.

Stephane

ps : sorry for english but my mother tongue is french.

Hey guys, I know I put this on the forums board but I pulling my hair
out here trying to get this to work.

I have this script to poll the iostat on a system for monitoring.
I want to make a graph for each /dev/* with the five fields being
graphed in a single graph, example /dev/hda would have the read, write,
wait, and percent in it.
#!/usr/bin/perl 
open(IOSTAT, "/usr/bin/iostat -d -x|"); 
while(<IOSTAT>) { 
if
(/(\/dev\/[\w\/]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)\s+([\d\.]+)/) { 
my %output = (device => $1, rkB => $8, wkB => $9, await => $10, percent
=> $14,); 
print "Device:$1 read:$8 write:$9 await:$10 percent:$14\n"; 
} 
} 
close IOSTAT;

I have create also the data_template, graph_template data_input_method
and so forth, but I can't get it to graph. Also the name of it is weird
on the rrd file. I have tried to follow the instructions in the
documents and use existing monitors as examples to try to get this to
work.

Please help me get this going.
Thanks,

Joe

Hi,

I want to graph prTable OID. I read the manual and it says to use SNMP -
Generic OID Template. I have 0.8.5a and I didn't find this template. 

I can't find it on the website either.

Can someone tell me where I can find it ?

Thanks a lot.

For everyone, and those who caught my "More Documentation" thread, who 
know the kind of documentation I'm looking for on SNMP, so I can build 
my background for Cacti.  Does anyone have/read

Essential SNMP
O'Reilly
By Douglas Mauro, Kevin Schmidt

Would anyone recommend this?  Does it have good tutorials, walk 
throughs, along with the background, theory etc..?  If my local 
Barnes&Noble doesn't have it, so I can take a look, I'll have to amazon 
it.  Any other book suggestions.  The online docs are getting me nowhere.

thanks, Kevin

Helps to know what distribution / version you are running...
You might check either freshrpms.net or rpmfind.net.
You're needing the snmp and openssl RPMs.

I have a remote HP-UX 11.00 host that has SNMP enabled. When I created the new
device for it I selected Generic-SNMP. I then went through the motions of
setting up checks for available disk space on the remote host. According to the
rrd.log file, the rrd file for the remote host was created in the in rra
directory along with the localhost files.

The permissions for the cacti directory, located under /usr/local/apache/htdocs,
and all its subdirectories and files is 777. 
What else do I need to do in order for me to see the remote filesystems?

This is the rrdtool parameter to generate a graph and not the file. The 
file creation should look something like

/usr/local/bin/rrdtool create - 
/usr/local/apache/htdocs/cacti-0.8.5a/rra/space_hdd_total_17.rrd

Also, you don't need to have the dir. permissions as 777. Just make sure 
that the user from which the cmd.php script is being called has the 
write permissions (ownership) to write to the rra dir and the log dir.

What happens when you run the cmd.php script from the command prompt and 
not via cron? Do you get any errors?

Haven't gotten down to the local barnes & nobles yet to check out whats 
in print.  I've sat down and tried  a bit, but spent more of my time 
trying to get situtated in how the entire system works.  Like I said, 
I'm having trouble finding documentation that says more than, this is 
piece A, this is piece B, piece C.   I need to know how that work 
together, and some examples would be great.  I'm like most people, I 
learn best when I'm reverse engineering something.  Saying, Egg, Milk, 
hot pan, all about the IEEE Egg Standard (IES) doesn't tell you how to 
make scrambled eggs.

This isn't a matter of not knowing networking.  This is a matter of not 
knowing SNMP.  One can network all you want and never use SNMP as I'm 
trying.

For a shop that has ZERO monitoring, anything is an improvement.  Plus, 
I'm just in the exploratory phase on all this.  There will certainly be 
some testing to do.

This is a general complaint of mine about OSS documentation, open source 
coders write great code, but they are not good writers.

I have a remote HP-UX 11.00 host that has SNMP enabled. When I created the new
device for it I selected Generic-SNMP. I then went through the motions of
setting up checks for available disk space on the remote host. According to the
rrd.log file, the rrd file for the remote host was created in the in rra
directory along with the localhost files.

GPRINT:b:MAX:"Maximum\:%8.2lf %s\n" 

However, when I went to the directory in question, there were no rrd files for
the remote host. The apache error log files confirmed the remote host files did
not exist with errors saying the files did not exist. Shown below is an excerpt
from the error.log file:

The permissions for the cacti directory, located under /usr/local/apache/htdocs,
and all its subdirectories and files is 777. What else do I need to do in order
for me to see the remote filesystems?

Have you purchased the o'reilly SNMP book?  have you just sat down and
*tried* stuff?  It's not that hard, really.

Not to be a jerk, but, I think you mean it IS anything but simple.

Yeah, well, that's real life.  You can't very well monitor a bunch of
networking stuff knowing nothing about networking.  You can't implement
an SNMP-based metrics system (cacti) knowing nothing of SNMP.  And
previous to that decision, you can't very well know if a UDP solution is
right for you if you don't know any of the pitfalls of UDP.

While I agree to some extent, if it were so simple as to need *no*
prerequisite knowledge, you wouldn't get paid too much, now, would you?

After spending a day looking around, I'm no better off where I began.  
While there is documentation out there, its all scattered,  nothing is 
consistent in following through any sort of configuration.  There are no 
real world tutorials.  There is nothing I've found that takes the many 
portions: clients, MIBS, scripts and combines them into a comprehensive 
whole.

I now understand all the jokes about SIMPLE-NMP not being anything but 
simple.  Tools at issue, net-snmp, ucd?-snmp, scripts all are open 
source (which is good), they do however suffer from what I believe is 
the biggest roadblock to OSS, thats crappy and 'elitist' (we assume you 
already know half of what you need) documentation.

I would assume one could easily walk through, say, config to read proc. 
usage on a remote client within a few pages.  This I can not find.

Try capturing stdout/stderr from the cactid run and looking through
it for obvious things.  Using 'grep -i error' liberally on the output
can be very helpful.  I tend to save the output from the last 20 or so
cactid runs just so I have something I can go back to.

Here's a curious issue, the answer to which I've been unable to find in
the archives.

If I run cactid instead of cmd.php, several of my data sources get
skipped.  It's the same ones consistently (all of one Data Input
Method).  Any ideas?

I know that's a little vague, but I don't have a good starting point,
yet.

Thanks Steve :-)

Looks like a permissions error on the ntop RRD files :-)
I'll sort that out later..

Thanks again.

Hey Steve,
  Yes I did that shortly after I sent the email.
The output is the following....

<!-- Round Robin Database Dump -->
<rrd>
        <version> 0001 </version>
        <step> 300 </step> <!-- Seconds -->
        <lastupdate> 1084882081 </lastupdate>
        <ds>
                <name> counter </name>
                <type> COUNTER </type>
                <minimal_heartbeat> 300 </minimal_heartbeat>
                <min> 0.0000000000e+00 </min>
                <max> 1.2500000000e+07 </max>

Etc etc...
So the name of the DS is "counter" and the data type is set to "COUNTER".
This I've checked, but the graph just comes out as a little red[X] in IE to
denote a missing image :-(
 
Cheers
Si

You might also try doing a dump of the rrd file to XML just to be sure
that the occurrence of COUNTER you're finding is in fact the ds name and
not something else (given that COUNTER is also a valid data type).  You
can dump the file using 'rrdtool dump /path/to/rra/file.rra'.

You should see a string like so:

        <ds>
                <name> ds0 </name>

Where 'ds0' is the data source name in this case.

You might also try doing a dump of the rrd file to XML just to be sure
that the occurrence of COUNTER you're finding is in fact the ds name and
not something else (given that COUNTER is also a valid data type).  You
can dump the file using 'rrdtool dump /path/to/rra/file.rra'.

You should see a string like so:

        <ds>
                <name> ds0 </name>

Where 'ds0' is the data source name in this case.

Hey all,
  Using cacti, and I can quite happily say it rocks :-)
However, I have one issue reading data from ntop generated RRD files.
I've asked on the  ntop list and the DS names are always COUNTER, (I've even
run "strings" over the rrd files to verify this) but its just not generating
graphs... and I can't find out why.

Its using other rrd files fine.

http://www.chuffnuts.org/cacti/graph_view.php?action=tree&tree_id=2
(resource graphs tree)

I've set it up in exactly the same way as my other graphs, but its simply
not showing... is there any extra debug info I can get from somewhere ?

Cheers
