Hi all,
I'm writing a shell script to get the information if postgres is or is not running.
#!/usr/bin/ksh
# the path to the PID file
PIDFILE=/var/lib/pgsql/9.2/data/postmaster.pid
if [ -f $PIDFILE ] ; then
PID=`cat $PIDFILE`
if [ "x$PID" != "x" ] && kill -0 $PID 2>/dev/null ; then
STATUS="There is a pidfile, YES, Postgres is running."
else
STATUS="There is no pidfile, Postgres is not running."
fi
else
STATUS="There is no pidfile, Postgres is not running."
fi
echo $STATUS
The script above works.. But, is there any way to get the same information, but with the checkpoints?
When you have a huge shared_buffer, when stopping the postgres' process, it will take some time to get it running again, right? Because the server will be writing a checkpoint?
So I'd like to check that... Is it possible?
Cheers
Lucas
