Gaps in graphs for only one host

[Tutur]

Hi,

I come to seek some help here.
I'm having around 200 hosts on my server, all these hosts are hosted on Google Cloud, same region for all.
Everything's working fine but for one server.

For this particular server, here is an example of graph that I have :


It happens for all the graphs of this particular host. All my items type are Zabbix Agent or Zabbix Agent (Active).
On all the other hosts, with same templates, same items, etc, I don't have this issue.

I'm a bit clueless. Anyone has an idea ?

Hi,

This happened to me once. The problem was coming from an item that was doing a http check, that was timing out, and it was messing up all the other items.
Try to check if you have hanging items, or a firewal that is blocking too many things.

I'd recommend to upgrade Zabbix, these issues were recently being fixed.
