Re: Custom metrics using IMetrics interface

IMetric and the metrics parts in storm are built on top of storm itself. If you need something that sends out metrics more regularly then Imetric does, just send them as regular tuples to a bolt you setup to collect them. - Bobby From: Xueming Li mailto:james.xueming...@gmail.com>> Reply-To:

Re: The role of supervisor in Storm

The supervisor will launch, kill and monitor worker processes. The monitoring is done through heartbeat files that the worker process writes out periodically and the supervisor reads in. The supervisor itself is expected to be run under supervision. This means that you need an external proces

Re: High CPU utilization after storm node failover

+1 for failure testing. We have used other similar tools in the past to simulate different situations like network cuts, high packet loss, etc. I would love to see more of this happen, and the scheduler get smart enough to detect these situations and deal with them. - Bobby From: "P. Taylor

Re: Is it possible to use Log4j 2 with Storm 0.9.0.1?

Re: Rolling Upgrade from 0.91

0.9.1 to 0.9.2 is not possible to do a rolling upgrade. The data structures stored in Zk and on disk have changed in a non-backwards compatible way. Most EBFs we do rolling upgrades. For them we install the new yinst package on all of the nodes and then restart the supervisor, logviewer, nibs
