Before 3 days, all beats are sending data properly on my elastic instance.
I was noticed new version is available. So, I upgraded all beats including elastic and kiban from 6.2.3 to 6.2.4. (i am using all beats accept winlog.)
After up-gradation, everything working as it is, accept filebeat and packetbeat not sending _source data to elastic search. On kibana's discover tab, only date is showing and next _source is empty. But i can see some hits are coming by upper side graph's visualization.
I checked everything(from last 2days), but don't know what i missed...
Please suggest me, regarding it.
