update ruby to latest version 2.2.2

[nyoung]

I am running ruby 1.8.7.374-4.el6_6 on my nagios xi server. I would like to update it to the latest version (2.2.2) but 'yum update ruby' says there are No Packages marked for Update.

The nagios version is Nagios XI 2014R2.7 on vmware (from the ova).

Is is possible to upgrade ruby? Is 2.2.2 supported by nagios? Is there any documentation on how to perform this upgrade?

Thanks.

I may be wrong, but I don't recall that we require ruby to be installed on the Nagios XI server... Do you need it because of a custom plugin that you are using?

[nyoung]

Yes, it is for a custom plugin

If your plugin supports ruby ver. 2.2.2, you could upgrade the package. As a precaution, backup your XI instance, create snapshots, etc. It never hurts to play it safe.

Is there another supported method of upgrading ruby?

You are going to have to build it from source.
