My zabbix server has a high load after migrate to 7.0.2 from 6.4
Attached an image.
I scaled the server, but still happen.

Hi,

Since this graph does not tell us much, I would suggest to find the cause of the problem by looking into Zabbix server metrics.
For example, top tool might be useful to investigate what is causing such a load.
You might want to check the load metrics for 10 mins by executing:
top -b -d 10 -n 60 > top_output.txt

Additionally, you might want to increase the debug level to at least 4 to check if there are any problems on server side, but the first step would be to see the origin of the CPU load (as above).
