Cacti SNMPAgent - v0.2.3 (released 28/Oct/15)

#1 Post by browniebraun » Thu Feb 28, 2013 3:54 am

Current version (0.2.3) of SNMPAgent can be downloaded >>HERE<<

Dear Cacti Community,

I'm happy to release the initial version of a new plugin called "Cacti SNMPagent" today.
All in all it is a pretty small base plugin, that allows you to monitor Cacti on its own or by using a foreign application in combination with SNMP. Therefore Cacti got its own MIB.
I'm pretty sure that some of you will directly notice that this initial release does not support SNMP notifications as well as other Cacti plugins.
This will be part of the second release I'm currently working on.
From my point of view BOOST and THOLD are the most interesting plugins in that case and I will write an additional MIB for both of them after consultation with the other core developers.

However, I'm looking for your specific feedback on this plugin and probably some of you will have a good mind to create some sweet templates for it.
One example has already been included.

Best regards
-Browniebraun

Two examples showing the poller runtime and the poller utilization.
The poller utilization will be calculated in relation to the configured poller interval at the bottom of every polling cycle.

that's pretty interesting

I can see the advantages of owning more than one NMS solution, and one being able to effectively monitor the other and thus give the user the ability to better troubleshoot discrepancies on data

Hello,
I'm trying to install this plugin and I'm a bit stucked, I'd appreciate some help. I see that there's a CACTI-SMI file, where should I put that, because I'm having the following error(prolly because of that file missing) :

snmpwalk -v 2c -c cacti_get localhost -m CACTI-SMI .1.3.6.1.4.1.23925
No log handling enabled - turning on stderr logging
Cannot find module (CACTI-SMI): At line 0 in (none)

It depends on your local setup of net-snmp where a copy of that MIB file has to be stored. At least you do not need the option "-m CACTI-SMI" to run a query against the local snmp agent.
I'm so sorry, that I haven't released the next version of this plugin so far. Currently I'm totally busy with the extension of our house without having real free time for programming during the last 2 months.
However, 90% of the new version are ready and the lasted SVN commit is quite stable. I've completely rewritten the persistent script and added functions to maintain the SNMPcache easier. Other Cacti plugin are allowed to hook into the SNMPagent to make their own MIB data available. Under Utilities you can also take a look at the SNMPcache or trigger a rebuild if necessary.
I've already written a MIB for Thold and Boost in the meanwhile. And after I'll have added the last 10% of SNMP trap handling I will release the new version and probably a mod of THOLD.
Need to discuss that with Jimmy first.

Hi Andi,

this looks like an awesome addition and I can see a lot of usefulness! My primary interest would be trending "Host polling times";
as in: how much time did a poller spend on each host. I know the medium debug information has an output of "Total Time" but
polling via SNMP instead of parsing log files would be way nicer.

Please let me know if this would be possible in future releases!

Cheers and greetings from Hamburg,
Andre

Dear Community,
Today I released a new minor version of the Cacti SNMPAgent plugin.
The agent of this release will perform extremely better on mid-size / hugh Cacti environments. ( My environment: >2300 host, >190K data source items)

Regards

Just a note for all of you who would like to use the Cacti SNMPAgent 0.2.2 together with Cacti 0.8.8c:

All new hooks required for this plugin became part of the Cacti core. Patches are not required.

Hello Brownie,
Is there a manual on howto config/use this plugin ?. I got it, installed it from plugin management tab, but except a "notification" tab nothing seem to happen.

The manual is part of the download package. Take a look at /plugins/snmpagent/docs/manual.pdf.
Additionally you can review the utilities for SNMPAgent under "Console->System Utilities".

Hello browniebraun

I have installed snmpagent plugin but i am unable to snmpwalk the Cacti MIB's after following the manual. Results of my snmpwalk below

Code: Select all

[email protected]:/usr/share/cacti/site/plugins/snmpagent# snmpwalk -m +CACTI-MIB -v2c -c public localhost .1.3.6.1.4.1.23925
CACTI-MIB::cacti = No more variables left in this MIB View (It is past the end of the MIB tree)
[email protected]:/usr/share/cacti/site/plugins/snmpagent# snmpwalk -m +CACTI-SMI -v2c -c public localhost .1.3.6.1.4.1.23925
CACTI-SMI::cacti = No more variables left in this MIB View (It is past the end of the MIB tree)
Also in the SNMPAgent Cache under Utilities all the items show up there correctly but when i also look in the cacti logs i dont see anything there for snmpagent.

Secondly does the MIB setup or persist.php script setup in snmpd.conf need to be working before snmptraps can be sent successfully?

Your help will be very much appreciated.

Thanks

Let me start with your second question:
There is no relationship between the SNMP trap feature and the persistent daemon.
You only have to define the path to the snmptrap binary and to setup your notification receivers.

If the snmpd.conf has been setup correctly and the net-snmp process has been restarted, you should see two additional
processes running after your first SNMP walk/get or bulkget request against the private enterprise ID of Cacti:

a) persist.php (this process responds to requests coming from Net-SNMP internally)
b) mibcache.php (this process refreshes the mibcache being used by the persistent daemon in the background once a change has been detected)

If persist.php is not running then there is something going wrong with your configuration in most cases.
You can also start the persistent.php script manually to verify that the mibcache will be build up correctly.

<path_to_php> persistent.php
Type in "PING" (upper case!) + Enter and the script will answer with "PONG". After that type in "debug" + Enter and the script should return the complete content of the mibcache. Additionally a temporary file called "mibache.tmp" will have been automatically being created in subfolder "/snmpagent/tmp/".

Hi Browniebraun,

I am currently using Cacti 0.8.8g on CentOS. I managed to follow the instructions and got the following error:

Code: Select all

pass_persist .1.3.6.1.4.1.23925 /usr/share/webapps/cacti/plugins/snmpagent/persist.php
Take a look at the bottom of my log. I am only able to run the snmpwalk one time, after that I get a constantly Timeout: No Response from localhost.

Is there a way to troubleshoot why suddenly is just get a Timeout: No Response from localhost?

If I remove the pass_persist, everything works fine.

I believe this happened if a print statement has been executed instead of fwrite, but I'm not absolutely sure. It's a long time ago that a was working on that code that last time. Line 131 of persist.php should definitely been changed from:

Code: Select all

fwrite(STDOUT, print "NONE" . $eol);
to

Code: Select all

fwrite(STDOUT, "NONE" . $eol);
But I'm not sure if this fixes your issue. On my development server I can executed multiple SNMPwalks without having timeouts. :o
