Matthew Clarke commented on NIFI-1462:
--------------------------------------
I know that # processors and cpu load is already included in system
diagnostics, so maybe be dumb to put it in 2 places. We could add the
additional information there instead.
We should also improve that "system diagnostics" system tab. I don't think the
information in that tab should ever be cumulative of the every node in the
cluster, it breaks down the value of the information presented. I think it
should provide a selection menu where you can pick the node you want to see the
stats for. We should also include disk utilization for all repos and state
directories. We should never sum and provide average across a cluster for disk
utilization. Provide no real diagnostic info that way. Repo stat could say it
is at 50% utilization and i think it is fine, while in fact that 50% average is
caused by Node X being at 99%. Not sure if this should be covered under this
ticket. sorry if it isn't.
> NiFi should log environment information on startup

> Key: NIFI-1462
> URL: https://issues.apache.org/jira/browse/NIFI-1462
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Reporter: Mark Payne
>
> When users have questions on the dev@ and users@ mailing lists, quite often
> the first response they receive is to request information about which
> operating system they are running, max heap size, etc. NiFi should log all of
> this information on startup, so that it is all very easily gathered.
> Things to include:
> * Operating System (name & version)
> * Java Vendor
> * Java Version
> * Min Heap Size
> * Max Heap Size
> * Garbage Collector
> * Max # of open files for user
> * Max # of processes for user
> These may not all make sense for all operating systems / environments but the
> info should be gathered when it does make sense.
