When I look at https://github.com/jenkinsci/extras-memory-monitor/blob/master/src/main/java/org/jvnet/hudson/MemoryMonitor.java , it seems to indicate that the memory monitor inside Jenkins is unable to find /proc/meminfo and cannot find a suitable `top` command.  It decides that NONSTOP_KERNEL is not Windows, not AIX, and not Solaris.

If you can't install a workable version of the "top" command, then you may need to submit a pull request to add support for NONSTOP.

Thanks,

Mark Waite

Thank you Mark.

Could you please point me to the URL to submit a request to add support for nonstop.

Also, I need a confirmation if Jenkins server can be used after receiving this exception as this appears after Jekins service was started successfully.

Regards,

Meenal

The Jenkins Jira server is https://issues.jenkins-ci.org/

Jenkins is an open source project.  Submitting an enhancement request for support of an expensive, highly specialized environment (like NONSTOP) is unlikely to get any attention.  Even with 130 000+ installations, it is unlikely there are any other installations on NONSTOP.

If you need that support, and you have access to that hardware, you're the best candidate to submit pull requests to support that environment.
