Zabbix db watchdog processes more than 75% busy

[poleszcz]

Hi,

I have this alarm permanently on the dashboard.

"Zabbix db watchdog processes more than 75% busy"

How can I troubleshoot it ? What does it mean ?
Is there any corresponding configuration ?

Thanks in advance for your help

After deeper digging I found that metric for this process is not collected.
I tried to change the formula to get alarm cleaned - without a success.
I've checked on the server that there is no corresponding process... and voila...

Process was removed in version 3.4 so what I need to do is to remove the item and trigger.
