"Docker: Failed to fetch info data (or no data for 30m)" Occurs for All Computes

[ayhanilhan]

Hi,

Normally, Docker is running and Zabbix has access to all computes. Sometimes "Docker: Failed to fetch info data (or no data for 30m)" events occurs on all computes.

Any ideas about it?

Event details:
Docker: Name
Operational data: Docker: Name 2023-01-xx 14:51:57 xx.xxx.xx(hostname)

Trigger details:
Expression: nodata(/xx.xxx.xx/docker.name,30m)=1

Parent triggers
Docker by Zabbix agent 2

Zabbix Agent 2 (5.2.7)
Zabbix 5.4.7

I'm seeing something similar but only for one specific host. Nothing much different about this host AFAICT.

Zabbix 6.2.6
Zabbix Agent 2 6.2.6
