NagiosXI 2014/ Core 4.x with mod_gearman-1.5

[mon-team]

Hi guy,

We are planning to migrate to NagiosXI 2014/ Core 4.x with mod_gearman-1.5

Could you please confirm that the issue "Nagios XI Event queue stalling? (Mod Gearman)" discussed on this post "http://support.nagios.com/forum/viewtop ... 16&t=25594" has been overcome in this release?

We are now running NagiosXI 2012R2.9 and mod_gearman-1.4

Thanks

BR

There were multiple issues within that post. Specifically the event queue issue has a known fix, but does not need to be applied to all systems, so it will not likely be forced into the next update. Otherwise, I do not believe there should be any known issues with your update.

Hi guys,

I have a question for you.
We are going to upgrade our nagios XI to the latest version.
Do we need to upgrade mysql-server and posgresql-server? the script../upgrade can perform this for us ?

We are running mysql-server-5.1.73, postgresql-server-8.4 and nagiosXI 2012R2.9 on a Cent0s 6.5

Thanks
BRegards

Yes, the upgrade script provided with the xi-latest.tar.gz tarball will upgrade all pre-reqs to the version we require for that XI version. You should not have to manually upgrade anything individually. In many cases, if you upgrade beyond a version we account for in XI, it can cause issues, so it's best to let the upgrade script take care of it.

Hi support,
Thanks you for your quick response.
Let me ask another question about upgrading modgearman.
I read with attention the official documentation http://assets.nagios.com/downloads/nagi ... ios_XI.pdf.

It's clear for me the steps to do about updating a gearman server on nagiosXI:

cp /etc/mod_gearman/* /tmp/
rpm -e gearmand gearman-devel mod_gearman libgearman
cd /tmp
wget http://assets.nagios.com/downloads/mod_ ... x86_64.rpm
yum localinstall -–nogpgcheck mod_gearman-1.5.0b1-1.el6.x86_64.rpm

The official documentation doesn't mention anything about updating modgearman worker. Could you indicate us the steps to do this.

I have a look to ./ModGearmanFullinstallVersionCore4.sh. The script installs gearmand-0.25 gearmand-devel-0.25 mod_gearman-1.4 while we currently have these packages installed on our nagios workers:

[root@nagios ~]# rpm -aq | grep gearman
gearmand-devel-0.33-1.x86_64
mod_gearman-1.4.14-1.el6.x86_64
libgearman-1.1.8-2.el6.x86_64
gearmand-0.33-1.x86_64

That's means we have to do a downgrade?

Thanks you

BRegards

No, our rpm of gearman, includes the neb module and the worker both at 1.5. The major benefit other than many bug fixes, is that we support the use of the latest rpm based gearmand instead of forcing several year out of date versions. Using the yum localinstall command will cause gearmand and all needed parts to be installed properly.

[mon-team]

Please let me repeat my question:
What are the steps to complete on our remote worker systems in order to update modgearman worker.

Our remote workers had mod_gearman-1.4 previously installed?

[root@worker1 ~]# rpm -aq | grep gearman
gearmand-devel-0.33-1.x86_64
mod_gearman-1.4.14-1.el6.x86_64
libgearman-1.1.8-2.el6.x86_64
gearmand-0.33-1.x86_64

Thanks in advance for your response
BRegards

You will likely need to remove the previous rpms, as they will conflict with the official packages. Then run the yum localinstall as our documentation states, and start the worker. If everything was configured before, your configs should transfer over as well. Aside from not configuring the gearmand and neb module configs, everything is exactly the same as installing or updating an exising mod_gearman install on a nagios system.

It's clear for me now.
Thanks very much
Best Regards
