ups_mond - performing additional actions

[BASIS BCC]

Is there any way to use customer scripts when ups_mond receives signal about power interruption? I was looking into ups_conf but haven't found any possibilities. Many thanks for help, Marek

I don't see anything in ups_conf either. The only possibility I can think of is to add scripts into the shutdown process but it sounds like you're hoping to initiate something sooner than that.

Exactly, I'd like to inform users about power failure and possibility of shutdown. Marek

Guys

I'm no great sys admin on HP-UX but I'm going to face the same problem in a few days time when my first UPS arrives.

Thinking about the way that the ups_mond runs and what you and I want to achieve, say an email to me, a notice to users, an email to a remote server to also take action before the shutdown. Then if these things were in a normal shutdown script they would occur every time a shutdown/reboot occured right!

So I thought that because ups_mond first calls /etc/shutdown -h before calling /etc/reboot -h, I could do the following

1) delete /etc/shutdown because it is a link to /usr/sbin/shutdown

2) create a new /etc/shutdown that grepped /var/adm/syslog/syslog.log for a recent entry from ups_mond, and if found in the file, sent my email, etc etc etc, slept for 1 minute then executed /usr/sbin/shutdown -h and if not found in that file then executed /usr/sbin/shutdown -h immediatly

If anyone has a good reason why this would be a BAD way to do it, or has a better way then by all means please let me know before I try this out.
