Kibana (7.17.8) does not seem to recognize the @timestamp field in my index as a time field. The symptoms are as follows.
- In Discover, the "Show dates" box on the top right is missing
- The time series chart above the Document list is missing
- The Time column in the Document list is missing
For comparison, this is what the metricbeat-* index looks like in Discover
When I look at the index pattern for my index, I noticed that the @timestamp field does not have the small clock icon next to it, unlike the @timestamp field for the metricbeat index pattern.
Can someone tell me how I can change my index or index template so that Kibana will recognize the @timestamp field as a time field.
I have read some suggestion about dropping and recreating the index and index template. That is not desirable as the index is being used to ingest data coming in in real time, and the index template was created by a third party that I do not control.
Your help is much appreciated. Thank you.
