Support for Nagios 4?

[spicysomtam]

We installed Adagios following the instructions on the wiki. We originally tried to install it on centos 7.1, but had issues with adagios and reverted to centos 6.6. Because of the issues, we decided to follow the install instructions to the letter and installed Nagios 3. However, Nagios 3 is not being actively developed since there is version 4 and the question is: does adagios support Nagios 4? Over time we feel Nagios 3 will become buggy as its not updated to support later versions of Linux.

If it does support Nagios 4, can we have some documentation on the wiki? A good start would be upgrading to Nagios 4. Even better would be install guides for installing on Nagios 4, and active encouragement to install Nagios 4 rather than 3.

Thanks in advance.

Adagios itself has no problems with Nagios 4 (since from adagios perspective they are identical).

There is a problem that arises with some of the nagios extensions that adagios takes advantage of. For example:

• mk-livestatus (if you want status data)
• pnp4nagios (if you want graphs)

So far we have stuck to putting in our install guides that these extensions need to be up and running, and rely on the install guides for those specific projects (because it is hard for us to maintain documentation for the whole stack).

All that said, last time I check (about 12months or so ago), there were very few users of nagios4, and mk-livestatus had some basic problems which required patching nagios4, and nagios4 was not accepting those patches.

Usually I am not one to say which monitoring cores to use, but I believe for this reason many potential adopters of nagios4 have moved over to naemon, since it has mk-livestatus built in. Myself, I use nagios3 only because last time i check (again 12 months), it was the only one that works 'out of the box' using centos 6.x and epel yum repository.

At least mk-livestatus now supports Nagios 4 with no patches needed (I've tested 1.2.8b1 and 4.0.8, respectively). However, you may need to compile mk-livestatus yourself: https://mathias-kettner.de/check_mk_werks.php?werk_id=0276&HTML=yes

The check-mk-livestatus and pnp4nagios packages currently available in CentOS 7 do not work, but I don't plan on using pnp4nagios.

Another issue is the CentOS 7 package for Nagios 4 doesn't support reloading the service, but again that works if you manually compile and install Nagios.

Maybe a change with downtimes 👍

Here is a new install guide for Adagios with Nagios 4 running on RHEL7 (livestatus and pnp4nagios are working as well) https://github.com/opinkerfi/adagios/wiki/Install-guide
