SNMP errors and empty graphs

Post by maetrik »

This is my first Cacti installation and I think I'm almost there.

We're talking Cacti 1.2.16 and it runs on Ubuntu 20.04.2 LTS, NGINX 1.18.0, PHP 7.4.3.

I'm only trying to graph my local machine and I'm specifically trying to graph network traffic and speed. Per day, per week, per month, per year.

So I have created a "Local Linux Machine" device with "SNMP - Interface Statistics" as an associated data query. The re-index method has been set to "Verify All".

At the data sources menu I now have 4 traffic entries and I have created graphs for them. These graphs are empty and what I see are SNMP errors.

I've been using the cmd.php poller and it runs via a cron job.

So I think what I am doing wrong is related to this specific error:

WARNING: Result from SNMP not valid. Partial Result: U

I'd really appreciate some help to get me going.

Console -> management -> devices -> choose your device and click "Verbose query" in Associated Data Queries on line SNMP - Interface Statistics . Have you got any result?

Thanks! I had that configured but turns out it was not properly configured.

Still have to tweak some settings but I got it working by starting out with a very default config;

Code: Select all

For security is better to use other than default community string (public).
