We are trying to Flapping info in our service handler. We have attempted to use $ServiceNotes$ macro to capture that data. I setup the command and modified the xi_service_event_handler to include service notes. I am testing with a server where the service is considered to be flapping and the indicator is in what we think is servicenotes(at least thats the label). When I force state change the handler fires but ServiceNotes as we have set it up shows blank in my echo's to the log I create. I have included the associated pieces including my small log. I went through the macro doc and it seems ServiceNotes are ok with the service handlers. Looking for a different set of eyes to review. Right now Im only worried about the field being popbulated. Thanks John

Here are some things I would look at.

xi_service_event_handler code:
I would try wrapping this --servicenotes=$SERVICENOTES$ in double quotes, just in case spaces are throwing it off.

Service Handler Script:
Is this right? if [[ "$ServiceNotes" = *Service is flapping* ]]; then
Or should it be this? if [[ "$ServiceNotes" == "Service is flapping" ]]; then

And also, you can enable logging of event handlers if you go to Configure -> Core Config Manager -> Core Configs. In the nagios.cfg file, there should be an entry for log_event_handlers, probably set to 0. Set it to 1, and then it should log to /usr/local/nagios/var/nagios.log.
