SNMPAgent: Unable to find a poller

Post by 2canchew »

From the subject, i get that error in my logs.

Only device setup on a new installation is the localhost at the moment.
I'm not even sure what that error means or how to troubleshoot further, i can snmpwalk the localhost from the console and everything is working as far as can tell.

Cacti version 1.2.21

Disable the SNMP Agent and once you know how it works, and want/need to use it, you can reenable it. You can disable by going to Console > Configuration > Settings > Poller

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?

The last cacti install i did didn't have that feature so i took it to mean that cacti wasn't able to use snmpd to poll the localhost.

Because if you look at that log screenshot, no rra's are being processed and i cannot figure out why.

Spend some time with it. I suspect you don't have your SNMP settings right and as such the poller it timed out. It also looks like "boost" is enabled, or the localhost is just timing out. Seems very strange. It'll take you a while to get up to speed. We have a YouTube channel. You should watch some of Sean Mancini's instructional videos.

It's not just snmp.... script based queries like logged in users, memory usage, etc... aren't creating any data.

Everything is being run as user www-data and permissions are all ok, poller cron job is the same user.
I've tested executing some scripts manually and they return proper values.
I used the ds debug tool under the troubleshooting section and ds are readable/writeable, but they have no data.

I've done a few installs of cacti and we're using it in production at work so I'm not completely new to this but this is the first time I've ever encountered this problem.

Enabled debug logging for a polling cycle and there's no errors, but the main poller is creating an event every second until it hits it's maximum runtime

You must have poller.php in debug mode.

Look at cmd.php's --help option. Use the debug flag, or -V 3 to see what is going on.

Yea, but the reindex almost tells me that the poller has not been running for a while.

Run the poller by hand in debug mode now. It's poller.php. Use the force and debug options.

So in the SYSTEM STATS entry it's saying 8 rrd's processed. Normally it's 0.

Because you have boost enabled under the performance tab under settings.

Well that's weird. You sure RRDtool is installed? No other errors in the cacti log?

Re: SNMPAgent: Unable to find a poller

Post by 2canchew »

I agree, it's very weird.

Yes, RRDTool is installed. upon initial install i had run the poller manually and graphs were created with one data point.
There were absolutely no errors in the log at all so I threw in the towel and opted to re-install.

initially I had downloaded 1.2.21 via the website.
Just a note to Devs, when i cloned via git and got version 1.2.22 the installer threw an error on the first page that cacti wasn't reporting a version #.
This stopped the installer from importing the pre-packaged templates.

I couldn't figure out how to resolve so I just re-installed from the 1.2.21 tarball I had downloaded from the website.

After re-installing everything is working fine. No clue what the problem was.

When I say I re-installed, I dropped all tables in the cacti db, deleted the original root folder of the cacti files and started from that point.
I did not install any other packages, dependencies, etc...

It's all working now.

Thanks for your support.
