NagiosXI HA Recommendation

[rajasegar]

Nagios XI 2014R1.2 Ent Edition

Do you have any recommended High Availability solution for XI?
We are looking for a solution with minimal data loss.
This includes all the utilization data, comments, acknowledgements etc.

Thanks

In my opinion(tm)....

For local HA I trust and use the VMWare HA. For cross datacenter DR/HA I am investigating using DRDB Proxy from Linbit. Sat through their talk at the conference this year and it excited me about the potential. Actually sitting through a webinar with them today.

edit - Linbit can also do local HA if needed(if you aren't using VM, etc)

At this point you will have to roll your own. My Nagios XI HA presentation is up on youtube now, as well as Jeremy Rust's (from LINBIT). You may also be interested in Bryan Heden's presentation as well as it covered large environments.

Thanks. I will check out the recommendations. How does VMWare HA handle the file system level sync and also the DB's?

Thanks. We would prefer a HA solution supported by Nagios officially.

We do not "officially" support any HA implementation at this time. Though we will do everything we can to help you roll your own (within reason).
VMware HA is easy and well understood. If you choose to deploy the linux HA stack, you must have the talent internally to do so as it can be quite complex.

Ok. Just need to know the answer of these questions.

1) How does VMWare HA handle the file system level sync and also the DB's?
2) What is Nagios recommendation on the above?

1. You may find the following link interesting:

2. Whatever works for your environment. Again, we do not have a "position" on the different solutions, as HA is heavily dependent on your environment/budget/needs and the talents of your staff.

Well this is good for OS and HW failure but not NagiosXI the application which in our case requires restore from daily backup with loss of 1 day of data.

We would like to know if anyone has implemented a workable periodic sync of the following to the passive server/VM.
1) File system
2) MySQL DB
3) Postgresql DB

1) Shared storage in an HA configuration. See my presentation for more information.
2 & 3) Offloaded Databases in a cluster config. This can use the built in clustering for mysql/postgres, or you can use drbd to cluster the db. Again, see my presentation for more information.
