log info of worker
Hello everyone,
I got such an output from the worker's log file:
2014-04-19 21:15:27 b.s.d.supervisor [DEBUG] Worker
4986301b-55e7-4083-9d38-f931174bc7d3 is :valid:
#backtype.storm.daemon.common.WorkerHeartbeat{:time-secs 1397934924,
:storm-id "inSight-1-1397857615", :executors #{[10 10] [-1 -1] [39 40]},
:port 6706} at supervisor time-secs 1397934927
What does [-1 -1] in this line mean? Another question is, how do I know
whether a task is died or not?
many thanks.
Jun

The API about IMetric and the using of ThreadMXBean may be helpful,
just like the using of MemoryMXBean in the SystemBolt. You can learn
something from the code of SystemBolt.

I guess -1 is the task id of SystemBolt. The other question may need
others to answer……
