Hi Vishwanath,
Peter prepared great article how to configure alerting with templated dashboards - [url][https://www.percona.com/blog/2017/02/02/pmm-alerting-with-grafana-working-with-templated-dashboards/[/url]](https://www.percona.com/blog/2017/02/02/pmm-alerting-with-grafana-working-with-templated-dashboards/%5B/url%5D)
Alerting in grafana is very new and still under development.
btw, it is recommended to update PMM Server and client to the latest version.

Hi Vishwanath,
unfortunately, grafana don’t support such thing right now
But you can add instance name to the legend. [LIST=1]
[_]Open dashboard
[_]Click on the title of needed graph with alert
[_]Select “Edit”
[_]Choose the “Metrics” tab
[\*]add “{{ mountpoint }}” string inside “Legend format” field.
[/LIST]
