Hi, Is there a way to monitor the progress of a hinted handoff task?
I found the following two mbeans providing some info: org.apache.cassandra.internal:type=HintedHandoff, which tells me that there is 1 active task, and org.apache.cassandra.db:type=HintedHandoffManager#countPendingHints(), which quite often gives a timeout when executed. Ideally, I would like to see how many hints have been sent (e.g. over the last minute or so), and how many hints are still to be sent (although I assume that's what countPendingHints normally does?) I'm experiencing hinted handoff tasks that are started, but never finish, so I would like to know what the task is doing. My log shows this: INFO [HintedHandoff:1] 2013-12-02 13:49:05,325 HintedHandOffManager.java (line 297) Started hinted handoff for host: 6f80b942-5b6d-4233-9827-3727591abf55 with IP: /10.55.156.66 (nothing more for [HintedHandoff:1]) The node is up and running, the network connection is ok, no gossip messages appear in the logs. Any idea is welcome. (Casandra 1.2.3) -- Drillster BV Middenburcht 136 3452MT Vleuten Netherlands +31 30 755 5330 Open your free account at www.drillster.com
