I’am in Grafana v5.4.2
I have a problem with Grafana alerts on the graphs of my Elasticsearch data.
I have an Elasticsearch data source with the index name:"[metricbeat-]GGGG.WW"
Today is December 31, 2018 and my Elastic indexes were named in 2019.01.
The graphs work well, but since the renaming of the indexes, the alerts have the status “no data”.
I bypassed the problem by modifying the data source with index name:"[metricbeat-]*".
Is this a malfunction or does it require a different value for “index name”?
Thank you in advance.
