I wonder if you are aware of some kind of activity on CABI server. We have a customer that has Zabbix monitoring memory and cpu usage rate for reporting server but currently they are not using any of the available reports.
In the image below you can see the highs and down on the upper right graphic that refers to the CPU usage. These highs are being recorded at labor hours and at dawn, 3am or 4am.
It called our attention, since reports are not being used at the moment. Do you know if this is normal behaviour?
