Cacti poller ?

[droid]

We use CACTI to poll some 170+ servers.
Average of about 15 graphs per machine.

We started using cactid once the cmd.php poller started taking too long (250+ sec).

So... here's a benchmark for you:

01/30/2006 02:22:46 PM - SYSTEM STATS: Time: 111.2935 s, Method: cactid, Processes: 1, Threads: 20, Hosts: 176, Hosts/Process: 176

Machine is running Debian stable, NET SNMP 5.1.2-6.1
HW: IBM x335 - 1x Xeon 2.4 Ghz, 1GB RAM

Cacti is one f**ing great tool to work with.
It dazzles all of our clients with amazing graphs and leaves them speachless while they scrible the sums on the cheques

Thanks for this great tool, guys!

Your cacti.log file is too big. Please implement management such as logrot. Also, to get rid of the net-snmp message, please upgrade to 5.2.x.

Hi dude!!!

Sorry to bring up this subject again, but after upgrading to net-snmp-5.2.1.2-fc4.1 I still have this errors:

No log handling enabled - turning on stderr logging
read_config_store open failure on /var/net-snmp/cactid.conf
read_config_store open failure on /var/net-snmp/cactid.conf
read_config_store open failure on /var/net-snmp/cactid.conf

And somehow I can't have cactid run from crontab:

*/5 * * * * cactiuser /usr/bin/php /var/www/html/cacti/web/poller.php > /dev/null 2>&1

Interesting, Cactid 0.8.6i should be released soon. Let's see if that has any affect. Oh, and if you create that file and give the poller user permission to update it, does the problem go away?

Try doing the following:


mkdir /var/net-snmp/
cp /etc/cactid.conf /var/net-snmp/cactid.conf
chown -R cactiuser /var/net-snmp
chgrp -R cactiuser /var/net-snmp

Then comment out the database and user info in the top part.

Then run your poller as cactiuser via CLI.

Error went away for me.

TheWitness -
I am a long time Cacti user and a huge fan - I can't count the hours you have saved me.

I am in a position now where, for unrelated reasons, I cannot allow the cacti user writeable access to /var/net-snmp.

I know what the fix is based on the comments here and this error:
Cannot rename /var/net-snmp/cactid.conf to /var/net-snmp/cactid.0.conf

...but I can't seem to find out
1) What the purpose is behind touching /var/net-snmp when I have specified the config file on the command line.
2) What I can do to work around my current limitation (ie. point cactid somewhere that I have control over)

Thanks -
