This query checks the logs in the Gravwell tag for ingester connect/disconnect events and charts the frequency of these events per ingester. If you see an ingester disconnecting and reconnecting frequently, it means one of two things: either there's something wrong with your connection, or the ingester is getting periodically kicked by the indexer(s) due to inactivity. Either situation warrants investigation! Normally, ingesters should only reconnect after a software upgrade.
