I have installed Zabbix-server 5.0 on a Docker Container, following the official guide (for postgresql): https://www.zabbix.com/documentation/current/manual/installation/containers

After that, I installed a Zabbix-Agent 5.0 for Debian 8 on the machine that host the docker daemon (and the dockerized Zabbix-server), from the official source: https://repo.zabbix.com/zabbix/5.0/debian/pool/main/z/zabbix-release/zabbix-release_5.0-1+jessie_all.deb

When I configured the server and the agent (I used a template: Template OS Linux by Zabbix agent), I started to get good data from the agent, but inmediatly I got a Problem on the "physical" server (it's an VPS):

vda: Disk read/write request responses are too high (read > 20 ms for 15m or write > 20 ms for 15m)

I started to check the disk with nmon command, and I saw the spikes of 100% on the disk, but is not happening from more than 5 seconds, the rest of the time the disk maintains 5-15% of usage.

In the server I only have the Docker, the Zabbix-server with Postgres and Zabbix-agent. Nothing more. (I got the server because it was and old unused VPS)

Could you help me to:

  1. verify if this is a real problem and not a false-positive?
  2. verify if Zabbix is creating this issue alone?
  3. verify if there is a solution to this problem?

Thanks in advance

I have the same problem today.

But the problem was the agent's Hostname in the file "/etc/zabbix/zabbix_agent2.conf" diferent of the Hostname config in the Zabbix Server Host.

Now it's ok!
