There are 100+ servers on monitoring, servers are separated by groups.
Each group have a separate alert dashboard, in each dashboard are placed 8 graphs with 25 metrics & 25 alerts for them in each graph.
Alerts are configured in such way:
If no data or all values are null - set state to - Alerting
If execution error or timeout - set state to - Alerting
The issue: then the metric has no data - Alert notification via email show empty metric field, so the support engineer can’t understand which of 25 metrics was affected (downstate)
On metric picture there are many lines, so it’s very difficult to find failed one
Should be very good if metric with no data will be placed in email message, like on his picture
