We have over 100 servers that generate hundreds of emails every day using scheduled scripts (cron jobs) when the system/data is backed up or any other activity takes place. The email is sent to our network admin group, so a few people receive them every day. The issue is that we don't have enough time to go through each of them and verify if all the servers have been able to run their scheduled scripts and send the email. Is there an automated way to verify emails, using a client mail app or on the server side? I was thinking of generating an email only if the script fails, but what happens if that server is down?
Send email only if the scripts fail. And as HopelessNoob mentioned, for 100 servers, you should already have monitoring system in place to figure if a server is down. If not, it's high time you had one.
