Hey all,

I'm started to look into what the `zabbix-agent` is doing in order to understand the effect it has on my system.
I have come across the fact that the agent is excessively reading the `/proc` files.

Hey,
I want to limit the Zabbix agent to specific cores list so it will not interfere with other processes.

Is it possible to set the affinity of the Zabbix agent (without using taskset etc)?

Hi guys,

First time poster here. I've spent about a week trying to figure this out now. Long story short every 12 hours, Zabbix locks up while a massive amount of reads are done on the database. I've been unable to determine why or what would cause this. My first suspicion was housekeeper...
