Nagios Support Forum

Hi,

we have problems with notifications, once a problem is detected and the services fall sending the corresponding notifications, but when uploading the host and services, only some services send the recovery, for example, if the ping of a machine falls on the PING service is alerted, but when this service goes up it does not send the notification and this is random, since in another opportunity the same service if it sends the recovery, we have reviewed the templates of contact, of host, of service without finding anomalies.

  What most strikes us is that this only happens with equipment that is constantly losing communication, services always notify when the service falls, but only sometimes do it when they go up.

Hello, @Tatto. What version of Nagios are you using? There is also a chance that your services enter the flapping state when they go up and down too often. You could try disabling the flap detection in the /usr/local/nagios/etc/nagios.cfg file:

enable_flap_detection=0

Then run:

service nagios restart
