Interop with Server 2012

If you are used to this working out of the box with other versions of Windows Server, there are some catches you should be aware of.

**The following has only been tested using NagiosXI 2012R2.3 and Nagevlog 1.9.2 under server 2012)

1. The encryption no longer works. If you have a mixed environment and are running nsca encryption, you need to change it all to “NONE”.

For whatever reason, on server 2012, when it is encrypted with say 3Des, the alerts never make it to the inbound transfer. The underlying OS does see the traffic, just something in NagiosXI does not like the way server 2012 nagevlog is doing the encryption.

2. Alerting; Once NagiosXI receives in and sends it to the passive filter, you will not get a email alert. UNLESS, you go into the service, press the Advanced Tab, and enable Active Checks.

Not sure why that is, but that is the only way I was able to get email alerts to come thru. Just be prepared that you are going to get 2 alerts; the first one on the event and the second one saying it has recovered. Hopefully you understand that the recovery is not on the actual event, but the passive listener resetting itself.

Hopefully this saves you a weekend of beating yourself up like I did. It is the loss of my life for the past 72 hours that I dropped my rating down to Good rather than excellent…

Enjoy!
