[jira] [Commented] (NIFI-1462) NiFi should log environment information on startup

["Matthew Clarke (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-1462?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15130455#comment-15130455 ] 

Matthew Clarke commented on NIFI-1462:
--------------------------------------

I think the above information once collected should also be presented in the NiFi UI.  My thought would be to make this info accessible through the "about" link.  Clicking about brings up the existing pop-up that provides the running NiFi version, but also provides via an embedded link or second tab the above system information.

If possible, i would include number of CPU cores and system memory.  Knowing this additional information can help us optimize there NiFi.  (i.e - Over allocation of threads on processors, Available space to increase Heap, or heap set to high base don system available resources)

We don't want to assume those deploying the app know how to get all this information from the system it is running on. Knowing all this information can help with tuning NiFi. Just my two cents.

> 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.
