Disk request responses are too high Problem
Hello all:
This is my first post, so I will try to add all the information I have, to show you my issue:
I installed the docker server version of Zabbix 5.0 on a server with Debian 8 installed. With postgres and snmptraps (like in the documentation example for 5.0)
I installed the Debian 8 agent version for 5.0 on the same server, but as a package, to check the VPS machine. (maybe that's an error, but I guess no) (from here https://repo.zabbix.com/zabbix/5.0/debian/pool/main/z/zabbix-release/zabbix-release_5.0-1+jessie_all.deb)
After some miss-configurations (I used the VPS Ip instead of Container IP on the agent configuration file, noob error), I got my VPS monitorized: (ignore the first one, and the third is the docker container for the server, not configured yet)
After apply the template "Template OS Linux by Zabbix agent", I got data from the VPS, but I got a recurrent problem in a disk response time each 15 mins, with a random duration between 5 and 35min until autoresolve:
After some "OMGOMGOMGWTHell" finally used the nmon command to check what is happening: and yes, after few hours running the nmon, I could get the peak-rw at 100%, but I cannot find which process is doing that peaks, but in this server there are only docker installed, Zabbix-agent and the containers for zabbix-server, postgres. Nothing more. Maybe there is a miss-configuration in the number of checks per second that the agent or the server made and that creates the bottleneck?
I hope you could help me here, because I cannot find the root cause of these problems and they are freaking me out.
Thanks a lot.
