And, to help other folks coming in from Search Engines:

It appears that 2.9 clients cannot speak to existing 2.7 servers. This was an intentional design decision.

Thank you jsmurphy. I am asking this question because I use FreeBSD, and FreeBSD Ports only provides nsca 2.9 (See [1] and [2]). I am wondering if the maintainer for this port jumped the gun a bit and should provide a port for nsca 2.7. If I had a canonical statement from the developers stating that...

Is NSCA 2.9 considered "stable"? It is not clear to me if NSCA 2.9 is production quality yet. Here are some reasons: * I see several mentions on the web that 2.9 is not stable. See here . There are other similar comments out there, but I do not have time to find the links and post them her...

It seems that existing Nagios servers which use nsca 2.7.2 will not work with clients which run nsca-client 2.9: http://comments.gmane.org/gmane.network.nagios.user/73098 The packet size was increased in 2.9 that caused 2.9 clients to fail with older servers and 2.9 servers to fail with older client...

The Nagios log (/var/log/nagios/nagios.log) does not show any errors, although I enabled the debug option in nsca.cfg . Bah! So, it turns out that NSCA does not use the Nagios log! NSCA uses syslog, and therefore the debug messages are being written to syslog. In /var/log/messages , I now see the e...

I use Nagios 3.x. Many of my servers transmit passive check information using nsca-client. Most of these servers run nsca-client 2.7.2, and work fine. However, I have one FreeBSD 9 host which runs nsca-client 2.9.1, and something is broken. Does nsca-client 2.9 work with an older version of the NSCA...

The notes are not displayed everywhere. As far as I know, you can only view them in the Extended Information CGI . In my case, the notes are not displayed either in extinfo.cgi or status.cgi. In nagios 2, they were displayed in status.cgi and extinfo.cgi. It appears this should be the case in Nagio...

We recently upgraded our Nagios 2.x installation to Nagios 3.2.x . We used to provide `notes` and `notes_url` as part of the hostextinfo, like this: define hostextinfo{ host_name host1, host2, host3 notes These are special hosts notes_url https://wiki.example.org/problemsolving/SpecialHosts } define...

I am running Nagios Core Version 3.2.3 , which was recently upgraded from Nagios 2. This is CentOS 5.x I want to test Nagios notifications, and clicked on the "Send custom host notification" button, and added a custom comment to the "Comment:" which said "Test, ignore."...
