Ubuntu Linux OS Processes

[wdw]

I am running Ubuntu 22.04 and Zabbix 6.4.15. I am wanting to see/monitor the OS Processes. I have the template 'OS Processes by Zabbix Agent' selected and applied. However, I do not see any data as it relates to the OS Processes in the 'Latest Data' or anywhere else for the host.

Do I need to add anything in the Zabbix Agent configuration file? I'm likely missing something small and hoping someone can point me in the right direction.

Access the discovery part and see if there are any errors, if not, check the zabbix agent logs for that Linux

If possible, send here a print of the discovery tab on the host and also the last 100 lines of the agent's log!

yours sincerely

I found this error in the logs:
3846296:20240712:191018.630 using configuration file: /etc/zabbix/zabbix_agentd.conf

I need to figure out what is using that key I think.

So I setup a fresh Ubuntu 22.04 host and installed the Zabbix Agent. The only two templates attached is 'Linux by Zabbix Agent' and 'OS Processes by. Zabbix Agent'. I still get no active data from the host regarding OS Processes. The zabbix_agent.log shows only the following:

There are no errors in the log file. The zabbix_server.log file on the actual Zabbix server shows no errors either. Is there a way to make the logging more verbose such as showing debug output?

Yes. Both the zabbix_agentd and the zabbix_server have manual pages that should have been installed with the packages. There is a runtime-control option described in the manual page. It can be used to dynamically increase or decrease logging.

Send me the zabbix-agent file settings and check the Zabbix-Server/Proxy logs for this host to see if anything appears

Thank you. I increased the logging on both the agent and server. I saw that Zabbix was indeed pulling the OS Process list. However, I do not see the information under the 'Latest Data'. Should it show there or am I missing something else. Thank you again in advance.

Yes, I checked if there are templates that only work in version 7.0 above, are you sure you uploaded a template version that works in 6.4?


If yes, you will do the following:

Enter the Zabbix-server command line and run:

zabbix_get -s <ip_host> -k agent.ping

replace <ip_host> with the Linux IP you want to monitor and check if the command is executed, if it is not executed, it could be a problem with permission to run some remote commands, this is configured in the agent, check if it is, if so let me know, anything sends the output here

When I tried it, I had a hard time realizing that I needed to change the parameters of the macro after adding template [OS processes by Zabbix agent].



It was necessary to specify the name of the process that you wanted to monitor or the name of the process that you did not want to monitor.
It seems that if {$PROC.NAME.MATCHES} is set to null, information about all processes can be obtained. (Not recommended as there are too many)
If you enter part of the desired process name, for example zabbix, information about zabbix-related processes will be retrieved.
You can further narrow down your search with {$PROC.NAME.NOT_MATCHES}.

I hope this can be of some use as a reference.
