Elastix reboot: cron job?

Also relying on itself to tel you if it's successful or failed isn't that great, you really need another machine they connects to it to make sure it's up and then sends an email if it's not.
That's why you use the monitoring system for that, rather than the maintenance system. Let it handle its own maintenance and the centralized monitoring that should exist anyway can handle the monitoring.

Monitoring it is much easier when centralized. We'll never move to doing tasks on Servers individually.
Monitoring should be centralized, agreed. But the actual maintenance?
Yes, By saying it's not you are suggestion Group Policy and WSUS are bad.

Group Policy pushes out the changes, but runs them locally. It would be more like having a centralized script that set the crontabs to always be the same (or in a pattern or whatever.) I think that GPO is more as I have described, local maintenance jobs.
WSUS is patching which is a little different. I would prefer WSUS use localized patching and centralized reporting and filtering.

And don't translate "sub-optimal" as bad. But don't think of GPO as centralized pushes of management either.
I'm totally for the cronjobs being pushed out centrally, that makes sense.

If you feel that that was what I was saying, are you implying that you feel that Chef, Puppet, cfEngine and other DevOps tools are bad? (They run locally and only pull centralized configurations.)

As for e mail, it would be nice to get a health report on successful boot.
No report, something is wrong....

It sounds nicer than it is. But in reality you don't want emails saying that things are okay, that's fundamentally wrong. For a couple of reasons:
- At scale, you will be inundated with "everything is fine" emails. It just doesn't scale.
- It trains you to ignore your email and messages from the server. It's bad conditioning.
- You have to notice the absence of an alert to realize that something is wrong rather than the presence of it. You have no way to verify failure, you have to hope that you remember when success was supposed to, hope that you paid attention, etc.
- This doesn't give you a means of passing off to another person or connecting to other automation.
- You have to maintain a list of people to be alerted of "regular stuff."
- You are attempting to use your email as a logging system rather than as an alerting mechanism.
-
If you want this kind of information consider something like...
- Using proper logging and looking in the logs for this information rather than in email.
- Posting to a status feed (e.g. Twitter) with status info that anyone can look up if they care to.

That's backwards you want emails when something fails. I'd get way too many if I got once when things worked I easily get 200+ per day already.

I rant that over in my mind, and it seemed that if the reboot failed, you would not get any type of email.

If you have the device itself send the emails. But normally you'd have something else checking status of the network services that would email you after X number of failed attempts to contact the device. We use OpManager for this but there are free tools to do it, spiceworks though bloated can do it. And there's a million and one linux based network monitoring tools.

Icinga is really good. I've got a Nagios server deployed right now to do this type of thing, that works fairly well although I really haven't dug too deeply into it.

Exactly. Think of emails as an alert. Logging success (somewhere, not email) is good so that you can always have that worried feeling and go look it up. Or just show someone why and when the reboot happened with some definitive info. But don't log to the alert system, save it for alerting. Make your emails matter.

If the reboot failed to run completely (like the system was down, cron had crashed, things were frozen) you would get no email either. You are making the system report on itself with is not good.
That's why the system should reboot itself (no way around that) but the monitoring of whether it is up or not should be done externally.
