Grafana Database Connection Error After Refresh the Page

[korbolko]

Hello.

I’m using Zabbix Plugin on Grafana and i’m drawing data from Zabbix.

Problem is when i refresh the dashboard page sometimes i’m getting Database connections errors.

Some panels showing the data some are not. Any idea why this is happening ?

Thank you in advance

Update

We fixed the problem, it was happening due to postgresql database configuration.

We simply increased the Shared_Cache size and Connection Numbers in postgresql configuration.

Your your information.
