@skkosuri-amzn Thanks for confirmation regarding the destination part. Data is present for 7 Days timeframe, I checked by reducing the timeframe to 1 hour but no luck.
We are using xpack security with elk version 7.6.1 and the standalone OD alerting plugin.
Pls suggest furture steps.
1.I suspect it may happen due to OpenDistro is not supported with xpack security. OpenDistro comes with native security.
2.Opendistro alerting will not work with kiban security. Try without security it will work.
