Nagios Support Forum

Hello all, I am new to this forum, but a seasoned IT veteran. I have successfully built Nagios Core 4.0.8 on CentOS 7 VM and it is up and running, but has not been tested to monitor anything yet other than the local host. PNP4Nagios and Check_MK are also installed and running, but also not tested yet. I am heading in the direction of building the system so that it will support distributed monitoring and have been looking at Mod-Gearman. After reading other posts here and looking at ConSol's site, I am hitting the pause button and wondering if this is a good direction to go or not. Seems as though development activity was pretty active between 2010-2013, but no new releases since and current BP/guidance seems to indicate that attempting to run Gearman on anything newer than CentOS/RHEL 6 will not be stable. I am also having doubts about Core 4/CentOS7 stability and realize a downgrade may be in my future, but also know that the collective communities will eventually get it figured out. So for the time being, does anybody have an opinion about this roadmap or have a better suggestion about which components to use for building a distributed system?

Thanks in advance!

I recommend Nagios on Centos 6.5 (or now, 6.6) since 7 doesn't really give you anything more except some fairly major ways that the OS is managed are different. Nothing wrong with change, but Nagios 4.X and CentOS 6.X are perfect together.

As for mod_gearman, we will discuss that when we have our discussion next week.

Just a heads up, you can get a 64bit gearman rpm (with the newline and core 4 fixes) from: For 64-bit CentOS/RHEL 6 Nagios servers: For 32-bit CentOS/RHEL 6 Nagios servers:
