I’ve been happily running Nagios at work for over a week, but I got a certain itch that’s bothering me and I cannot seem to figure out.
I installed Nagios on June 26. Did some tests, notifications arrived as nagios@domain… but I wanted notifications to arrive with a different name, so I recompiled nagios on July 1st and configured hosts with NSClient.
Now, When I do all-time trend reports, it gives me this huge period from June 26 until July 1st. that says status ‘undetermined’ for all hosts, and July 1st to July 3rd all UP. I don’t like this, and want my All-Time trend reports to start on July 1st so they say Up 100%.
Question is, How do I reset, or fix the trend reports so that when I do an All-Time report that starts on a specific date (Jul 1st). Note: I don’t mean the custom reports where you specify a time range.
