Assume that “local-testing” in the next image is a server that in the past sent data to Grafana, but not anymore. Altough its not used, it still appears in the list of “servers”. This is an issue because if:
- I have some alert that look for null values;
- I use a wildcard, e.g. “local-*”, to set the data source;
The alerts will fire up because the wildcard will catch the legacy server, which will have a value of null to whatever parameter I’m looking at.
Is it possible to remove data sources, like the “local-testing” in the example, from the list?
(I’m still not totally into Grafana terminology, so I might be giving weird names to things )
