Thread: Email monitoring
Should we set up a dummy email list that I can send to in an automated way every hour? If I don't get a reply in X minutes I can send out an alert to people. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://postgres.enterprisedb.com + If your life is a hard drive, Christ can be your backup. +

Email is blocked but there is no notification except "Hey, I haven't gotten email in a while". -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://postgres.enterprisedb.com + If your life is a hard drive, Christ can be your backup. +

Adding a completely different address for that is not really a good monitor. There are at least these problems possible: - routing problems - mail server problems - list server problems - machine failure problems - delivery problems These each need different monitors, I suggest. Let's work on those. A

Let's work on those. OK, but I have no idea how to monitor those, just email send/receive. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://postgres.enterprisedb.com + If your life is a hard drive, Christ can be your backup. +

'k, well, all this would do is test if mail was blocked to you, but not necessarily to everyone else ...

True, but I thought that would help. Historically, I thought most failures were for all users. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://postgres.enterprisedb.com + If your life is a hard drive, Christ can be your backup. +

But i'm all for a working mailinglist solution instead some workarounds to check a non-functional setup. Bruce: if you setup such a system you (but nobody else) knows about a problem. What use will be this system, if you are offline, away or just sleeping? So we need some more people sending mails periodically and check the result. This will result in a lot overhead and i assume in some false (and some true) positives.

This is what I thought. I want to avoid adding monitors for things that are already monitored at a lower level, because it just means more alerts with no additional benefit. A
