Re: [Zope-dev] Zope Server Control
You misunderstand: I have zero code. :-) The screenshot (especially the second one) shows precisely what I'm looking for in a Zope controller. It should scale up to dozens of Zopes and ZEOs while remaining useful for single Zope instances, it should display rapidly flashing lights to indicate exactly how resources are being spent, and it should display a Zope logo so it doubles as a marketing tool. Consider the screenshot a request. Ah sorry I thought you would have just quickly knocked one out ;) I think the Controller is a very useful tool and very good for marketing its really helped a lot of people with Plone. I can post the QT .ui file, though, if that would help. ;-) Im hopefully getting a good UI designer (ie not me) on line for helping out with the UI for this. I was actually thinking of wxPython rather than Qt, but thats just a personal preference.

Maybe it would be of some use to develop an the app so that the clients for getting the status for zope servers could also be used as "plugins" for nagios. Encapsulating the classes used for getting the data from a zope server into a module would suffice, then one could write simple monitoring apps as described here: http://nagiosplug.sourceforge.net/developer-guidelines.html cheers, oliver ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

The buttons work; you are not clicking with enough pressure. Try again until your wrist hurts. ;) I agree, this looks nice. I also wonder about adding total memory usage for each Zope ZEO client.

Please explain. mix 1 part ssh, add shell script to taste It would be trivial, for example, to set up a shell script which itterated through your client hosts running 'ssh $host svc -t /service/zope' sending SIGTERM to the processes to restart them, or substitute svstat, svok, etc. for different results. Tie commands to ssh keys for added security. It would be safer (wouldn't require super-user privs) though to poll status using an apache-style server-status handler. The downside to that is that if zope is wedged or down you must rely on a timeout as an indicator (though there's nothing horribly wrong with that, its just not very precise). One of my plans for a side projects is adding more logging to zope so that I can cull server status information from my logs, which may to some extent, provide finer granularity with less overhead. -- Jamie Heilman http://audible.transient.net/~jamie/ "...thats the metaphorical equivalent of flopping your wedding tackle into a lion's mouth and flicking his lovespuds with a wet towel, pure insanity..." -Rimmer ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

So we can either run with -D even though it turns on all kinds of crap that you may not want on a production server, or write a wrapper zope script that runs in the foreground and signals Zope when you signal it.

Okay, I added some features to the mockup: http://hathaway.freezope.org/Images/controller_snapshot2.png Now the right-hand panel is a scrolling window with expand buttons to the left of each process being monitored. That way, this little GUI can scale up to monitoring large clusters or many independent Zopes. I also added a "debug" button to one of the ZEO clients, which would open a Python prompt in a window. I imagine that the interface to the backend would be a TCP connection with simple text commands and asynchronous replies. Using TCP this way makes it possible to use either a local connection or SSH to connect to the server being monitored. As for PyQT vs. wxPython, either one is fine. I also lean toward wxPython, partly because its license is simple.

RE: [Zope-dev] Zope Server Control
I agree that this is a good idea. Doesn't PyQt require a commercial license on Win32? The de-coupled backend is a good idea, and I would love to have alternatives - I'm a bit slanted towards wxPython, myself. ;) Heck, I would love to have an curses-based alternative to manage, monitor, and provide an interface to restart all ZEO clients and ZSS boxes in a terminal; this would make for easier remote admin via SSH from potentially different client platforms. For larger ZEO clusters, it would make a lot of sense to have consolidated management.
