Red Spikes on Zabbix Server Health Dashboard

[kishchan777]

Good Day,

can anybody help identify what are these red lines on my Graphs. They just started to pop up this month. I am also getting the alarm Zabbix server is not running: the information displayed may not be current.

Please check the settings of the graph you are looking at. Have you enabled "Show problems" in the Problems tab? I think it's probably because of that setting that the time period when the failure occurred is displayed in red.
