Design two Nagios Failover/Redundant topology - need help !

[karen9876543210]

Hello !
I am using nagios core 3 ! and I am trying to make failover monitoring, according to nagios documentation (Redundant and Failover Network Monitoring,Scenario 2 - Failover monitoring) it work fine. For last service state information on backup host, I am using ocsp command on master, and nsca addon on backup host .

The question is - if my backup host go down, send nsca will fail sanding data , and after comming up I will not have history on my backup host . Is there any solution exept rsyncing logs ?

And the second question is - is there any solutions for nagions to read/write plugin output data, perfdata and history in/from mysql ?
Thanks

If you're referring to the state history (host/service up/down at time), rsync is probably your best bet for Nagios Core.

And the second question is - is there any solutions for nagions to read/write plugin output data, perfdata and history in/from mysql ?

NagiosQL does a little bit of this. Might solve parts of your use-case.

Thank You for response !!
NagiosQL is for configuration, keepeng configuration in database, and web ui for configuration!
I do not neet that, I need some tool to pull out host/service status data, check output data... fom mysql to nagios ! is there any available ?

I don't know of any solution that sends the logging info and performance data from Nagios Core to a MySQL database. NagiosQL really is the closest thing to that, but I understand it is not a 100% solution to your use case.

Nagios XI includes some of that information in MySQL tables, but the back-end is almost exclusively using the RRD files for performance data and the log files for reporting.

There is ndoutils for sending data from nagios core to mysql, but I need opposite opportunity !! From mysql to nagios !!
Also I find out that it is possible to compile nagios with mysql support !!

is this because you want to keep it in sync or another reason?

A lot of modifications / addons have been made for Core, while what you posted above may work, it this isn't something we can directly support. Let us know if you have any further questions.
