nmon for Linux

Latest response

I would like to see nmon installed by default as well as a admin tool that gives you a huge amount of important performance information in one go.

Have you looked at dstat?
It appears to be similar in functonality and supports CSV output for analysis in third party tools as well.

Try nmon frist, it makes dstat looks like a toy. "nmon" has made it into AIX as default install for a good reason - enterprise class tool!

Hi Vincent: What features of nmon stand out for you? What makes nmon enterprise-class to you?

nmon has a nice interface, but on Linux it doesn't give you anything that dstat doesn't. On the contrary, especially with the pile of available dstat plugins, dstat provides much more capability.

I'd sooner vote for htop in fact, which is a vastly improved top.

Fully agree, we have included htop in our kickstart templates long time ago.

I'm indifferent in this coversation, but I do have some input.

nmon I believe has become a defacto-standard on AIX to troubleshoot.  I imagine the shops that have an AIX install would probably like the similar capability cross-platform.  I was a Solaris guy prior to jumping back to Linux, so I don't have any expectation to improve the tools.

 

Also - I think Nigel is basically just a geek at the end of the day (which I say as a complement) and when I heard him speak at an IBM event and the adoption of his product on Linux you could visibly see his excitement.  I like to see the endorsement of Linux by industry leaders (which I feel he is).

 

So, perhaps I'm not entirely indifferent, I guess I am in agreement that nmon would be a nice-to-have in RHEL 7.

Can we make nmon available via EPEL?

You may try to open a RFE at https://bugzilla.redhat.com/

I have submitted the RFE. https://bugzilla.redhat.com/show_bug.cgi?id=1378282

Beware: according to the nmon download page at http://nmon.sourceforge.net/pmwiki.php?n=Site.Download, nmon may not be that useful in x86_64 architectures:

"Notes on 64 bit Intel/AMD: nmon for Linux can be compiled 64 bit but it is largely pointless as nmon does not use 64 bit features like using more then 2 GB of RAM. If you have 64 bit processors and you are running a 64 bit Linux then you can still run the 32 bit nmon for Linux but only if you have the 32 bit compatibility Linux libraries installed. For a single server, this is a "no brainer" install from the Linux install media. Some users have thousands of machines like a High Performance cluster and would rather avoid installing the 32 bit compatibility libraries on all nodes. "
