Hi,
I have installed the virtual appliance of pmm 1.5.2. So far everthings works as expected.
I configured a named user with “grafana admin” rights and tried to login at [url][http://mygrafana/graph/login[/url]](http://mygrafana/graph/login%5B/url%5D). I get this message and no hints in the logs:
Server side error ☹
runtime error: index out of range
Check the Grafana server logs for the detailed error message.
Does anybody got an idea about the cause and how to fix it?
regards
---

Daniel,
Were you able to check Grafana Server Logs as message instructs you ? Percona Monitoring and Management includes complete Grafana, including its logs.
Also this issue looks like Grafana related more help might be available on Grafana Forums
