Nagios stopps scheduling checks when ndo2db is not available

[linxiao.geng]

Hi,

I'm setting up a new Nagios/Centreon environment using ndo2db. After everything's done, I just noticed that whenever Centreon server is not available, Nagios simply throw out such messages and stop scheduling checks.

[1343126113] ndomod: Error writing to data sink! Some output may get lost...
[1343126113] ndomod: Please check remote ndo2db log, database connection or SSL Parameters

I was using Nagios 3.4.1, NdoUtils 1.4b9 and Centreon 2.3.8. I suspected that this was something introduced by new version of Nagios, I downgraded Nagios to 3.2.3. Which is a version we know it should work when ndo2db is gone, because we have another environment is using this version of Nagios and ndo2db. We never had this problem in this environment.

The strange thing is, after I downgraded Nagios to 3.2.3, I have the same behavior as before. Can anyone point out where could be the problem?

I don't know much about Centreon, but if the MySQL database is on the Centreon server and ndo2db is configured to use that database, then I would expect it to run into problems when the Centreon server is unavailable.
