LDN - Luminis Developer Network

Here's something I came up with to get an idea of how much we see various errors in our logs.

It's schedule as a cron job. It's pretty rudimentary, but it's better than nothing. We're on Solaris, should work mostly unchanged on Linux:

#!/bin/sh

############################################################################################
# Step 0 - setup
############################################################################################
. /opt/luminis/.cprc
DTSTAMP=`date "+%Y-%m-%d %H:%M"`
FILENAME=/tmp/error_notification.txt
FILEHEAD=/tmp/error_header.txt
FILETEMP=/tmp/error_errors.txt
echo "Errors logged as of $DTSTAMP" > $FILEHEAD
echo "When activity is low, the same errors may be reported several hours in a row." >> $FILEHEAD

############################################################################################
# Step 1 - check for errors and write to $FILETEMP
#          Note: This won't be perfect, doesn't scan cp.log by date/time, so older
#          errors might be reported more than once.

## Check a: ParallelTimeoutMergingPersonAttributeDaoImpl.java
ERRORCOUNT=`grep -c "ParallelTimeoutMergingPersonAttributeDaoImpl.java" $CP_ROOT/logs/cp.log`
if [ $ERRORCOUNT -gt 0 ]; then
        echo "$ERRORCOUNT ParallelTimeoutMergingPersonAttributeDaoImpl errors" >> $FILETEMP
fi

## Check b: failed to renderState error
ERRORCOUNT=`grep -c "failed to renderState" $CP_ROOT/logs/cp.log`
if [ $ERRORCOUNT -gt 0 ]; then
        echo "$ERRORCOUNT 'failed to renderState' errors" >> $FILETEMP
fi

## Check c: Error creating group for course
ERRORCOUNT=`grep -c "Error creating group for course" $CP_ROOT/logs/cp.log`
if [ $ERRORCOUNT -gt 0 ]; then
        echo "$ERRORCOUNT 'Error creating group for course' errors" >> $FILETEMP
fi

## Check d: Error finding user
grep "Error finding user: " $CP_ROOT/logs/cp.log >> /export/home/cpadmin/log/errorfindinguser.log

## Check e: Can't service request to /cp/home/logout
ERRORCOUNT=`grep -c "Can't service request to /cp/home/logout" $CP_ROOT/logs/cp.log`
if [ $ERRORCOUNT -gt 0 ]; then
        echo "$ERRORCOUNT 'Cant service request to /cp/home/logout' errors" >> $FILETEMP
fi

## Check f: channel rendering errors
CALERRORCOUNT=`/usr/xpg4/bin/grep -c -e u12l1n37 -e u13l1n36 -e u14l1n46 $CP_ROOT/logs/cp.log`
if [ $CALERRORCOUNT -gt 0 ]; then
        echo "$CALERRORCOUNT calendar channel errors" >> $FILETEMP
fi

## Check g: cpip external user id error
ERRORCOUNT=`grep -c "CPIP ERROR sctssb Unable to create exter" $CP_ROOT/logs/cp.log`
if [ $ERRORCOUNT -gt 0 ]; then
        echo "$ERRORCOUNT 'Unable to create external user id' errors" >> $FILETEMP
fi

## Check h: Can't service request to /cp/home/next
ERRORCOUNT=`grep -c "Can't service request to /cp/home/next" $CP_ROOT/logs/cp.log`
if [ $ERRORCOUNT -gt 0 ]; then
        echo "$ERRORCOUNT 'Cant service request to /cp/home/next' errors" >> $FILETEMP
fi

## Check i: "generating cache key" error
ERRORCOUNT=`grep -c "generating cache key" $CP_ROOT/logs/cp.log`
if [ $ERRORCOUNT -gt 0 ]; then
        echo "$ERRORCOUNT 'generating cache key' errors" >> $FILETEMP
fi

# Step 2 - mail file
############################################################################################
if test -s "$FILETEMP"
then
        echo "." >> $FILETEMP # triggers end of message
        cat $FILEHEAD $FILETEMP > $FILENAME
        mailx -s "Luminis error report" -r "from@school.edu" to@school.edu < $FILENAME
fi

# Step 3 - cleanup

rm $FILETEMP
rm $FILEHEAD
