Robert, I like the idea, but there are a few details that need to be nailed down. For instance, what did you have in mind for how users configure these e-mail notifications? How should Probe store them? I can imagine several possibilities.

Perhaps the settings are stored in a file which can be uploaded (or downloaded) through Probe. Perhaps Probe provides a web interface for editing the settings directly. What happens if the server is restarted, though? Are those settings persisted somewhere on disk or would they have to be configured again?

I like the idea to be able to set the email settings (sender, mail-host, auth, receiver) in the web-interface. We can persist it to a property file.

I've been trying to think about where these files would be stored. We wouldn't want them stored in webapps/probe because they would disappear if Probe is undeployed. However, Hudson stores its settings in the user's home directory. I think that's the perfect place to persist these settings, too.

Filed issue 108 to represent saving these settings across restarts.

For now, they will be configured through command-line properties.

To clarify, this issue is only going to cover setting up the framework for mail notifications. Adding the notifications themselves to specific features will be covered by separate issues. For memory usage notifications, see issue 158 .

We'll want to link to JavaMail properties in our documentation of this feature since users will need to at least set the mail.smtp.host property. http://java.sun.com/products/javamail/javadocs/com/sun/mail/smtp/package-summary.html

Renaming 2.2 milestone to 2.2.0.

Labels: Milestone-2.2.0

padcom commented 9 years ago

From MALfunct...@gmail.com on April 17, 2011 08:27:15

There is a lot of design work that needs to go into this feature.

It makes sense that the email notification would be tied to stats collection. Should it continuously notify while the threshold is exceeded? Depending on the collection interval, this could be a flood of emails. Should it notify once when the memory threshold is exceeded and once again when it falls back below?

What if the value is alternating between two values, one above and one below (as can happen with memory usage between garbage collections). Should it stop emailing when it reaches a "flapping" state, and then resume again when it's stopped "flapping"?

This issue is being delayed so it doesn't hold up PSI Probe 2.2.

Thank you for considering adding this feature. I hope it gets included in the next milestone.

I like the idea of notify once when the memory threshold is exceeded and once again when it falls back. Would it be possible to set a second threshold and send a second notification if the trend is keep going up and not garbage collect interval has not kicked in? By having second threshold, it gives an opportunity to advise collection if necessary.

I personally have not really experience the alternating between the two values (below and above the threshold). I think it's a great idea of stop email when it reaches a "flapping" state and resume after it no longer "flapping".

I got the ideas from Nagios. http://www.nagios.org/ I think it would be possible to have a second threshold, but considering how complex this is becoming, I think we may need a design document.
