So it seems obvious now that the Unix Agent is a requirement for all applications, but given that this was the first time I'd set up an application it wasn't initially. At least not to me. Seems to work fine once that's done.

Thanks,
Geoff

Observium connects to the client on the unix agent port 36602.

You can test if this works by telnetting to 36602 on the client machine from the Observium server.

The script runs successfully on the agent. How are the results of the script on the agent sent back to the server? It doesn't seem that they are through SNMP. Is it possible that the applications expect a password-less SSH configuration?

You can manually run the script (or the agent script) on the client machine to see if it runs.

I've done this and the MySQL application does not show up for the host, and if I manually run the poller there is no <<mysql>> section in the output. I'm using the SVN release of Observium and the server I'm trying to monitor is Debian 6 with MySQL version 5.1.something. I have tested with the firewall disabled, using the user/pass set explicitly in a mysql.cnf file, and without using the one provided in the agent-local directory.

Couple of questions. Does the version of MySQL matter? Is there a good way other than the poller to check against the server to see if it's authenticating correctly? Aside from logging in using the credentials in the /etc/mysql/debian.cnf file, I've done that and it works.

It needs to be run on every host running MySQL that you want to monitor, as that is the user the script uses to connect and collect metrics with.

The instructions for configuring the MySQL application at https://observium.org/w/Application/MySQL are unclear about where the database user must be created. Do the user create steps need to be done on every host running MySQL that you want to monitor, or just once on the Observium server? I assume that it's the former, just looking for clarification.

Thanks,
Geoff
