So most of the time I don't want an email every 15 minutes that the script ran and logged to the db, just if the temp is high.
Sorry, but that's no script. That is a plan after which to write a script, at best. Most probably your script bears Cron Problem Number One, but that is just a wild guess as long as you post rubbish instead of your failing script.

I hope this helps.

NAME
rt-email-dashboards - Send email dashboards SYNOPSIS
rt-email-dashboards [options] DESCRIPTION
This tool will send users email based on how they have subscribed to dashboards. A dashboard is a set of saved searches, the subscription controls how often that dashboard is sent and how it's displayed. Each subscription has an hour, and possibly day of week or day of month. These are taken to be in the user's timezone if available, UTC otherwise. SETUP
You'll need to have cron run this script every hour. Here's an example crontab entry to do this. 0 * * * * /usr/bin/perl /opt/rt4/local/sbin/rt-email-dashboards This will run the script every hour on the hour. This may need some further tweaking to be run as the correct user. OPTIONS
This tool supports a few options. Most are for debugging. -h --help Display this documentation --dryrun Figure out which dashboards would be sent, but don't actually generate or email any of them --time SECONDS Instead of using the current time to figure out which dashboards should be sent, use SECONDS (usually since midnight Jan 1st, 1970, so 1192216018 would be Oct 12 19:06:58 GMT 2007). --epoch SECONDS Back-compat for --time SECONDS. --all Ignore subscription frequency when considering each dashboard (should only be used with --dryrun for testing and debugging) perl v5.14.2 2013-05-22 rt-email-dashboards(8)
All times are GMT -4. The time now is 04:42 AM.
