Shutdown logs

[Dimitri Karagiannis]

Hi everyone,

One of our clients wants to have a monthly report on all the downtimes our servers had starting from this month. Is there any file that is written that keeps track of everytime the server is shut down?

Thanks in advance,

Dimitri

Normal shutdowns are logged in
/etc/shutdownlog

for crashes, you would have to sniff around the /var/adm/syslog/syslog.log and /var/adm/crash

good luck

/etc/shutdown may not exist so make sure it is created. shutdownlog will keep a record of all shutdowns, normal (ie, operator directed), powerfails, and system crashes. For useful information about crashes, you must setup /var/adm/crash (preferably pointing to a very big area since each crash dump can be 100% the size of RAM (pre-11.0) or about 25% RAM (11.0 and beyond).

The 1-line reason for a crash is not too useful except to identify a crash has occurred.

Bill, don't you mean that /etc/shutdownlog may not exist. /etc/shutdown will exist as a link to /usr/sbin/shutdown.
