[Bauer-Lee, Sue]

And the entry for alerts.cfg to send an email notification?

Check out the UP parameter/setting in the analysis.cfg.  (https://www.xymon.com/help/manpages/man5/analysis.cfg.5.html):

UP bootlimit toolonglimit [color]

The cpu status goes yellow/red if the system has been up for less than "bootlimit" time, or longer than "toolonglimit". The time is in minutes, or you can add h/d/w for hours/days/weeks - eg. "2h" for two hours, or "4w" for 4 weeks.

Defaults: bootlimit=1h, toolonglimit=-1 (infinite), color=yellow.



So, you could add "UP 30m -1 RED" to either the DEFAULT stanza or to select hosts.  The CPU test will then have a "&red Machine recently rebooted"  at the top (similar to this<https://www.xymon.com/xymon-cgi/historylog.sh?HOST=brahms.hswn.dk&SERVICE=cpu&TIMEBUF=Mon_Jul_7_22:59:08_2014>) when the host's uptime <= 30m.

Hello All!

Times have changed a bit in the infrastructure environment such that many have a large contingent of virtual machines and blades. These hosts tend to reboot rather quickly, hence connectivity failures tend to not get noticed. I have a request on the table to send an email alert with a specific subject line to indicate that a host has rebooted.

I’ve seen a few posts over the years regarding requests to alert for system reboots. I also saw a post or two about adding a dynamic column capability. Some responses suggested an external script to accomplish the task of emailing an alert.

I’m asking the question again because as I peruse the analysis.cfg and review the rules, I know I can issue an email alert for PROC and DISK.
That begs the question of ‘why can’t I issue an email alert for UP’? I’m fine with the ‘yellow’ on CPU test for recent reboot, but since it also includes load changes, I’m not interested in a generic email for either one when they occur.

If I already can, how??

And if not, suggestions for a simple approach? I’m not exactly getting the desired results server-wide with an external script that should just send an email for a CPU status color=yellow without interfering with our other configured alerts. ☹

Is someone already successfully conquering this task?
