If a Collector goes down, the connected Agents will try to reconnect for 20 seconds. If it doesn't get available again during that time span, the Agents will fail over to a different Collector in that group.
My question is : Do we still get the agent connection lost alert during the fail over? Thank you.
Hello @xiaohe c.
No. There is no connection lost during this time.
If a Collector fails due to hardware or software failure, the Agents buffer data from a couple of seconds to up to a minute, depending on load. As a result, no data is lost if the Collector is started again within this time.
If the Collector comes up within a minute again, the Agents automatically reconnect to the Collector and the latter to the Server.
If not, the Agents can fail over to a different Collector in the Collector group.
