I’m looking for a good way to deal with noisy alerts due to No Value.
It seems like from time to time Grafana will fire these for whatever reason. I suspect due to being restarted or something similar. Unlike No Data or Error conditions, these alerts are not renamed to DatasourceNoData or DatasourceError, so I cannot filter these out.
Is there any good way to reduce the noise produced by these?
How does No Value differs from No Data?
