I think the user is fine, otherwise it would have never wrote something 
in that folder.

The userid should be the same that runs cacti.

Yes, there is some rrd files in it that where created by cacti.
But for some reason it doesn't always create them and actually it 
doesn't create any at all.
User and group is www-data .

Sounds like a permissions issue...=20

Hello,

When I try to create a new data source or graph, cacti doesn't create 
the according .rrd files.
For some reasons sometimes it do it.
I meanaged to do it for localhost but not other hosts.
snmp works fine on the other computers.
I run Debian Linux.

RRDTool Says:

Subject: [cacti-user] Measure Total Bandwidth Bcross Cisco Switch Backplane



Has anyone created graphs with cacti that will measure the total bandwith

I aint here to help you but to rather ask your advice, I am new to cacti and 
have been googking for about a week to try and get monitoring on our exchange 
server, but the defaults scripts that come with cacti do not work. Can you 
perhaps point me in the right direction.

I use cacti to monitor a slew of servers and network equipment and it
works great.  I am having a problem and I haven't been able to nail it
down to snmp or hardware.  One of my MS Exchange servers is monitored
for the usual stuff -- disk space, traffic, multiple cpu utilization,
and virtual memory.   This server has been having some weird problems
and I was hoping that one of you may have seen something like this
before.  The single most confusing symptom is the virtual memory graph.
After a server reboot, the graph jumped to 1.32 TB free with 324 GB
used.  The disk has stayed constant and it only has one 64 GB Raid. =20

What would be the prober command string to return the virtual memory
from the command line on my linux monitoring box?

I am having some difficulty with graphing snmp data returned from the
UCD-DISKIO optional mib module in Net-SNMP 5.1.2.rc1 using Cacti
0.8.5a.

Similar to SteveF's earlier post about this topic I ended up having to
construct my own net-snmp_diskio.xml using net-snmp_disk.xml as an
example.  The xml is attached.  

I created a ucd/net - DiskIO data query (snmp data indexed) with the
xml and Index Type, Index Value and Object Type ID are checked and set
to the defaults in the manual. 

I created a ucd/net - DiskIO Data Template (also with a input method
of snmp data indexed) and created 4 data source items to correlate the
output fields defined in my xml file, bytes_read, bytes_written,
fs_reads, fs_writes; each of these have 0 for min/max and are set to
GAUGE.  Index type, value and output type ID are checked and their
fields are empty.

I created a ucd/net - DiskIO graph template and associated it with the
ucd/net - DiskIO data query.  I have 4 graph items defined for each
data source with type = Line1 and CF type = Last; this also created 4
identical Graph Item Inputs that look correct.

This is the furthest I have gotten.  When I open up a ucd/net SNMP
device I see the associated ucd/net - DiskIO query and graph template
available, I goto "Create Graphs" and the data query successfully maps
the storage devices available for me to select, if I select one and
click Create I get this error:

"There appears to be a problem with your data query. Please make sure
you have made at least one data template association."

The section in the Cacti manual that describes this process makes it
seem like I have to go into the data sources section for each host I
want this on and add the ucd/net - DiskIO data template.  I did this,
but this seems very counterintuitive to me, wouldn't you just do this
to a Host template?

In my <Host> - DiskIO data source I left Data Source Path blank, and
in "Custom Data" Index Type says data sources must be created in New
Graphs, as does Output TypeID, I could only enter something in Index
Value and I don't really have a clue what it is expecting.  I have
tried using "diskIOIndex" and "diskIODevice" but something is wrong.
The DataSource debug mode shows the call the rrdtool to create the rrd
that gets filled into the DataSource Path.  

But the rrd file is never created.

I've re-read the manual sections several times, I've resorted to
trying random things to see if I can get different behavior but I am
getting nowhere.  

Can someone who has been down this path before offer a hint?  

Even if this works and I can graph diskIONRead, diskIONWritten,
diskIOReads, DiskIOWrites, it looks like this mib module only provides
counter totals since boot instead of over a set time interval.  I also
don't think the mib is working for diskIOLA1/5/15 for disk load
averages, I don't see them defined for any of the hosts I am hitting
with my data query. 

Any help or tips would be deeply appreciated, thx,

Hi, Jeff.  No known problems.

I think that RRDtool is very stable in the 1.0.48 version,


I know that the OS-SIM project http://www.ossim.net/
is using a June 10 snapshot of the 1.1 snapshot version.
The nice thing about RRDtool 1.1.x is its support for PNG and SVG formats.
No more proprietary G-I-F .
but I don't recommend people changing to it just to keep up.

You need to install the most recent net-snmp RPMs suitable for
your OS version.   net-snmp, net-snmp-utils, and net-snmp-devel.

Hello,  The file "cactid/snmp.c" invokes "init_snmp()", which
elicits a chain of events that may look for "snmp.conf" in well-known
places. This is normal and proper, should you be linking with the
Net-SNMP libraries.

Run "ldd cactid". Where the Net-SNMP libraries found in /usr/local/lib ?
If so, you may experience version skew problems if
the RedHat-supplied net-snmp RPM is also installed.
If this is a production system, you may be better served by removing
the /usr/local/lib/lib*snmp* objects, and force a relink of "cactid".


However, the presence of the equals sign character in the defVersion
warning is suspect.  Edit snmp.conf, change that equals sign to blank,
and rerun "cactid".  You should see improvement.


To understand what can be configured using snmp.conf, run
"man snmp.conf" [after installing net-snmp-devel RPM],  or run
"nroff -man man/snmp.conf.5.def | more" [if you have the net-snmp sources].
  

Please refer to the Net-SNMP on-line manuals here

The issue is with the Linux 2.2 and later kernel, not with snmpd.
The Linux kernel tracks statistics only for physical interfaces,
not for the aliases (or labels) that the deprecated "ifconfig"
program might allow users to refer to.  Sorry about that!

The fine points might be made clear by reading these messages
archived on the net-snmp-coders mailing list.

Is anyone successfully using RRDtool 1.0.48,
  or the RRDtool current snapshot with cacti ?

Tnx for replay.
I have found "rrd_path"
 in data_input_data_cache table.
But how can i get it if i have only  "local_graph_id" ?
 tnx.

The code would seem to show that that information is not stored in the
database.  Looks to be derived as $config["base_path"] . "/rra", where
that base path is the base directory from where Cacti PHP scripts run. 
I don't see the base path stored in the settings table, either.

When we have to get info. which is not available by SNMP, we run the 
scripts locally and use SNMP extensions to make the information 
available via SNMP. In the sample snmpd.conf from net-snmp look at the 
Extensible sections part. It will give you ideas on how you can 
accomplish the task.

This sounds simple but will be daunting and might turn out to be PITA to 
manage. Especially with the RRDs being updated, etc. Polling IMHO is 
always a better option than push.

Hi,

I intend to use cacti to many servers monitoring. If I'd use only SNMP
to do this, it would be easy, because the monitoring dedicated server
could take data from the other servers. Otherwise, there are many
information data that I need and can't be colected by SNMP, but only
by local scripts on each machine.

I thought to run the cmd.php on each server to colect data through local
scripts and send them to data base on mysql server. After this, the
monitoring server could read those data and plotate the graphics of
other servers.

I'd like to know if this is possible to use cacti this way and if
there is any documentation about this, because in the original
documentation I didn't find anything specific about that.

Best regards,

Alberto Bengoa

No, MySQL isn't broken (or not really). There is only one problem: 
MySQL on Windows has two users "@build" and "@localhost". You may 
add users at will. Since these are queried before the new users, and 
an empty username matches all users, the new users only have the 
rights these empty username users have.

Solution: delete these users.

Statistics report table in Cacti
=====================
Hello I'd like to have a "statistics report table in Cacti".
Has anobody already work on such an add-on for Cacti ?


My idea is the following.
For the time I don't have time to make any implementation, but if someone
can help me I will be great.



Format of report
============
Selection period:     YYYY MM DD HH:MM:SS     to       YYYY MM DD HH:MM:SS
                                                      min       average
max
graph_name1   legend_curve_11      x             x                  x
graph_name1   legend_curve_12      x             x                  x
....
graph_name2 legend_curve_21        x             x                  x
graph_name2 legend_curve_22        x             x                  x
graph_name2 legend_curve_23        x             x                  x



where
   -The graph1 has a name "graph_name1". On this graph we have 2 curves
displayed. The legend of the fisrt one is legend_curve_11
       The legend of the second one is legend_curve_12
   -The graph2 has a name "graph_name2". On this graph we have 3 curves
displayed. The legend of the fisrt one is legend_curve_21
       The legend of the second one is legend_curve_22, the third one is
legend_curve_23

   - The graphs selected will be the graphs selected in the "List View" tab
       For each curve the minimum, average and maximum are displayed

   - The minimum, average and maximum are computed from the chosen selection
period YYYY MM DD to YYYY MM DD

    - The graph will be a simple table in ASCII format.
         This ASCII format and the lines above will allows us to make copy &
paste of the information we want into Word, Excel, .... in order to make
reports

For instance in particular I plan to make an availability curve whom values
are either 0 or 100, therefor the "availability" column will be a percentage
of availability of the device in the month




Some elements to help in doing it
=======================
    - For the selection period, I would use a mecanism similar to the one
proposed in  "Cactistoric"  from     Bruno PRIGENT
       I have made proposal of modifications of the Message Board  "Scripts
and Other add-on for Cacti   /  Cool zoom/history feature for cacti :)" to
zoom on all the selected graphs in   Tree   or  List mode ==>  User
"Didier" at the end of all submissions.      I'll use the same mechanism
than in the preview mode.


    - To know which curve are displayed in a graph, an idea can be to detect
in the    rrdtool graph    all the       LINE 1,  LINE2   or  LINE3
instructions
       And then will have all the information  (the name of the variable +


     - To compute the    minimum,  maximum    and    average    I would use
the same  rrdgraph used to graph on which
        I would remove      LINE1  LINE2  LINE3  GPRINT
        For each LINE1, LINE2   or   LINE3 I  would have
                   rrdtool graph  --start <start_of_selection_period>  --end
<end_of_selection_period>    PRINT  <variable> : MIN  : %s
                   rrdtool graph  --start <start_of_selection_period>  --end
<end_of_selection_period>    PRINT  <variable> : AVERAGE : %s
                   rrdtool graph  --start <start_of_selection_period>  --end
<end_of_selection_period>    PRINT  <variable> : MAX : %s

        The  PRINT   instruction of    rrdtool graph   displays the results
in sttdout   so  I think it should be feasable to have it displayed on an
HTML window
        I would separate the computation of  min, average and max in order
to put them in the corresponding cell.

     - To access this   statistics view  if possible I would make a tab
"STAT"
        The "List Mode" will allow you to select the graphs, when clicking o
view you go to the "Preview Mode" for the selected graphs,   if after you
select the "STAT" tab you would access to this statistic report
