3.0n8 running on Suse Linux 11

[ravi108]

We are running Nagios Core 3.06n8 on suse linux 11 with a separate MYSQL server for reports.
MYSQL ver is 5.0.67. WE would like to move to a CORE version that is supported by Nagios.
Pl let me know the CORE ver that we can upgrade to with min disruption and also keep the MYSQL servers connected
with all funtionalities currently used ( reports/performance colection )
Thank you in advance for your suggestions/recommendations

What version of ndoutils are you using? Are you using mklivestatus, any other third party brokers, or any other third party addons? (nagiosql, nagvis, etc)

[ravi108]

So far ndoutils have not been utilized, but we plan on utilizing the plugin after consolidation.
ndoutil1.5.7 is installed.NO 3rd party or addons.

Are you sure that ndoutils is 1.5.7, the latest available is 1.5.2, and trunk has not been incremented for a sub version release either. At this time, I would suggest at least 3.4 but 3.5 would work just as well, and not require changes to the db or ndoutils provided you are on 1.5.2.

Is there an automated way of consolidating 2 Nagios servers after upgrading to CORE 3.5.
We have 4 nagios servers monitoring 800 windows/unix clients.
Plan is to consolidate them to 2 monitoring servers. Currently with CORE 3.06N8 we donot have any
graphical interface to perform import/export
Thanks.

No there is no way to do this beyond hand scripted solutions, this is partially automated along with many other tasks, in Nagios XI.

[ravi108]

Is there a limit on number of clients monitored using Nagios CORE 3.5 running on a SUSE Linux 11.1 VM.
Currently each Nagios 3.0 is monitoring 260 cleints. Plan is to consolidate them to one server with increased resources

[slansing]

There are no hard limits, but you will need to be careful depending on the server's hardware, how often you are running active checks, and what type of checks you are running. If you have 260 hosts, with roughly 4 services per host, that would put you at around 800-1000 services, which is not that much for a typical, modern server to handle. What are the hardware specs?

We are running on VM with following CPU 's: & 4GB ram. After consolodation we will be moving from $ nagios servers to 2 Nagios servers

While hardware requirements are not an exact science, the current specs you are running with should suffice. It gets tricky because some checks take a lot more memory or CPU (or both) and that get majorly skew any estimated specifications.
