check_uptime3

Thank you for this !!

I have been hunting and testing for MONTHS to find a check_uptime script that works correctly. This is the only one that does with the different results (depending on time up) from 'uptime'. i.e Minutes, Hours & Minutes, Days & Minutes, Day & Hours & Minutes.

I have made a few adjustments to mine as I have no need for warnings, just for monitoring:

==========
#!/bin/sh

UPTIME_REPORT=`uptime | tr -d ","`

if echo $UPTIME_REPORT | grep -i day > /dev/null ; then

if echo $UPTIME_REPORT | grep -i "min" > /dev/null ; then

DAYS=`echo $UPTIME_REPORT | awk '{ print $3 }'`
MINUTES=`echo $UPTIME_REPORT | awk '{ print $5}'`

else
DAYS=`echo $UPTIME_REPORT | awk '{ print $3 }'`
HOURS=`echo $UPTIME_REPORT | awk '{ print $5}' | cut -f1 -d":"`
MINUTES=`echo $UPTIME_REPORT | awk '{ print $5}' | cut -f2 -d":"`
fi

elif #in AIX 5:00 will show up as 5 hours, and in Solaris 2.6 as 5 hr(s)
echo $UPTIME_REPORT | egrep -e "hour|hr(s)" > /dev/null ; then
HOURS=`echo $UPTIME_REPORT | awk '{ print $3}'`
else
echo $UPTIME_REPORT | awk '{ print $3}' | grep ":" > /dev/null &&
HOURS=`echo $UPTIME_REPORT | awk '{ print $3}' | cut -f1 -d":"`
MINUTES=`echo $UPTIME_REPORT | awk '{ print $3}' | cut -f2 -d":"`
fi

UPTIME_MSG="${DAYS:+$DAYS Days,} ${HOURS:+$HOURS Hours,} $MINUTES Minutes"

echo System Uptime - $UPTIME_MSG
==========

I now have this running on CentOS, Ubuntu and Raspberry Pi servers, all running perfectly!

System Uptime - 0 Minutes
System Uptime - 4 Hours, 19 Minutes
System Uptime - 2 Days, 8 Hours, 54 Minutes

Hello,
This is a patch to use with Debian and optiomal min/max options

> PERFDATA="|Uptime=$UPTIME_DAYS;"
> if [ "$MIN_WARNING" != "" ] || [ "$MAX_WARNING" != "" ] ; then PERFDATA="${PERFDATA}${MIN_WARNING}:${MAX_WARNING};" ; fi
> if [ "$MIN_CRITICAL" != "" ] || [ "$MAX_CRITICAL" != "" ] ; then PERFDATA="${PERFDATA}${MIN_CRITICAL}:${MAX_CRITICAL};" ; fi

Works like a charm on my Raspberry Pi.

@cnoyes72: you can simply change the shell to: "/bin/bash", so the script works fine under Debian as well. Do this by editing the first line and replace "#!/bin/sh" with "#!/bin/bash".

Hope this helps. Cheers.

Executing this script on a debian system results in the following being reported (along with the results):


printf: 107: %3.4l: invalid directive
OK - uptime is 10 Days, 19 Hours, 25 Minutes|Uptime=;:;:;0;
