… so I'm trying to rotate logs on amazon cloud auto-scaled server instances every hour. I've created /etc/cron.hourly/logrotate to read:
#!/bin/bash
test -x /usr/sbin/logrotate || exit 0
/usr/sbin/logrotate -f /etc/logrotate.conf
And I've altered /etc/logrotate.d/apache2 to read:
/var/log/apache2/*.log {
missingok
rotate 100
create 640 root adm
sharedscripts
postrotate
neoBucket="widget-chapp/dev/log/";
neoService="apache";
neoDate=$(date +\%Y\%m\%d\%H);
echo "hostname: $HOSTNAME";
neoHost=`echo "$HOSTNAME" | sed "s/-//g"`;
# prepend neoService and append YYYYMMDDHH
for f in *.log.1;
do
mv ./$f "$neoHost-$neoService-${f%1}$neoDate";
done
# gracefully restart the apache service
apachectl graceful
# tar the files
tar -czf "$neoHost-$neoService-$neoDate.tgz" "$neoHost-$neoService-*.$neoDate"
echo "neoHost: $neoHost";
# send the rotated files to s3 bucket
s3cmd put "$neoHost-$neoService-$neoDate.tgz" s3://$neoBucket > /dev/null
# remove the individual log files
rm "$neoHost-$neoService-*.$neoDate";
endscript
}
… here's the question… how do I get the $HOSTNAME value… judging from output on line 10 in the postrotate block it's empty.

Guessing it's not in the path for that user. Try
/bin/hostname
