Nagios Support Forum

I've updated to Nagios XI 2014R1.0RC2 in my dev environment and love the interface, features, and can't say enough good things about it. I'm looking forward to the production release.
I removed mod_gearman and reinstall via the ModGearmanFullinstallVersion.sh --server command.
Once I restart nagios, following is the error:
Apr 23 10:11:11 nagiosdeva nagios: wproc: Registry request: name=Core Worker 2560;pid=2560

So it appears, I need an updated version of mod_gearman?

I do believe you are going to want the core4 branch found on github: https://github.com/sni/mod_gearman/tree/nagios4

THANK YOU!
I downloaded the package " mod_gearman-1.4_.rhel6.x86_64.rpm " since the other packages are the same. I ran " yum --nogpgcheck install mod_gearman-1.4_.rhel6.x86_64.rpm " which updated mod_gearman-1.3.8-1.e.rhel6.x86_64 to mod_gearman-1.4_nagios4-1.el6.x86_64.

Mod_gearman is now fully functional.
If you have any tips for mk livestatus, I would appreciate it!
I'm using the mk-livestatus 1.2.5i2 version with configure --with-nagios4

mrochelle,

Did you have to do anything to your workers or just the XI server? I don't have gearman in my dev environment

Actually, I have not done anything with the workers but I'm planning to update those boxes to Nagios XI 2014R1.0RC2 and mod_gearman this afternoon if everything else remains quiet.

Just a quick update reference my mk-livestatus comments.
Actually Scottwilkerson had a prior post with a version that will work.
cd /tmp
wget http://mathias-kettner.com/download/mk- ... 2.4.tar.gz
tar xzf mk-livestatus-1.2.4.tar.gz
cd mk-livestatus-1.2.4
./configure --with-nagios4
make
make install

Nagios XI 2014R1.0RC2 is fully functional on my configuration. I'm taking this Friday off to celebrate.

Now to decide if your testing is good enough for me

I have about 10 workers connected to the one XI server, so if all I have to do it reinstall gearman on XI once we update to 2014, that is nice and easy

EDIT: I of course mean after it is out of beta!

I believe that's all you really need to do. I completed updating my workers to Nagios XI 2014R1.0RC2 for consistency only. I did not have to touch the mod_gearman worker configurations.

I agree, the only change necessary should be on the gearman server a.k.a XI. The commands being pushed to the workers should stay constant, at least at this point. Further investigation will need to be done by myself or another team member that works on gearman integration in the future if this is changed but you should be good to go. Remote workers with core 4 are still in the process of being ported over and that *should* be a viable alternative as well.

I'm looking forward to the remote core 4 worker capability. If it meets or hopefully exceeds mod_gearman performance, that will be impressive. Will the remote core 4 worker capability be included before the 2014 production release?
