Kibana version: 7.5.1
-
Elasticsearch version: 7.5.1
-
APM Server version: 7.10.0
-
APM Agent language and version: java and rum
-
Original install method (e.g. download page, yum, deb, from source, etc.) and version: yum
-
Fresh install or upgraded from other version? apm upgraded from 7.5.1 to 7.10.0
-
Is there anything special in your setup? we use logstash in between apm-servers and elasticsearch for cache and pipelines such as user agent or geolocation
-
Description of the problem including expected versus actual behavior.:
I'm upgrading the apm stack from 7.5.1 to latest 7.10.0. Recently I upgraded first the apm-server(s) and logstash(s), next iteration we will upgrade elasticsearch and kibana.
Everything look continue working fine but since upgrade I see that apm connections on :8200 are dropping frequently, see screenshot with behavior before/after the upgrade (upgrade done on 8:00 of 2 Dec, a few hours later connections are reset every few minutes):
Rest is working fine and I don't see errors indicating something bad, Is there anything I could check to see what is causing it? is it normal continues reset of connections since recent versions maybe?
Thanks in advance!
