Can a host have both passive and active agents?

[xtonymarsx]

I just started using zabbix a couple of weeks ago. So I'm quite the novice. I tried to search the boards, but didn't see any similar threads.

Due to strict bandwidth and data restrictions, I have many of my hosts set up with passive agents, but I also need to do some log monitoring which can only be achieved with active agents (at least that's my understanding). Can a single host use both active and passive agents?

I verified that the proxy is listening on port 10051. On the agent config, I have left the default port as 10050 (for the passive monitoring), but also exclusively set the ServerActive=<proxyIP>:10051. In the agent log, I see that agent is now starting an active check, but I don't see any connections for 10051 in my netstat.

You're welcome!

One single agent can perform active and passive checks! So, yes, but you don't need to install it twice)
Take a look here https://www.zabbix.com/documentation...concepts/agent

Correct, 'Server=' for passive checks, 'ServerActive=' for the active checks.

In the agent log, I see that agent is now starting an active check, but I don't see any connections for 10051 in my netstat.

Hm, I think you forget to set 'Monitored by proxy' in the web frontend (Administration-Hosts-Host settings-Monitored by proxy). Please, check.

Thanks for the reply. Apparently I had it set up correctly. I had to clear the cache on the proxy for some reason before it recognized the new items/triggers that I'd created for the active agents.

Hi,

You can reload configuration cache by runtime control to apply changes immediately:

 sudo zabbix_proxy -R config_cache_reload
