[Zope] Medusa Monitor
Hi, Zope comes with the Medusa monitor (port 8099 by default) which is kind of cute and allows one to get into the guts of Zope. But do people really use it? How do people use it? Is there any document describing the usages of this monitor? Are there some features of this monitor that makes debugging easier? regards, Hung Jung _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: [Zope] Medusa Monitor
Use it for debugging sometimes. Is very easy to use. Basically import Zope z = Zope.app() then z is the root of your zope tree so you can do anything. You will need to import any other python modules you need too. terry Hung Jung Lu wrote: > Hi, > > Zope comes with the Medusa monitor (port 8099 by default) which is kind of > cute and allows one to get into the guts of Zope.

Re: [Zope] Medusa Monitor
Thanks for the follow-ups on Medusa Monitor. But as I can see (after using Zope for 1.5 years, now), few people actually use it. Unless one is really into the guts of Zope itself, the monitor is pretty useless for debugging. It of course could be made more useful, but one must implement some Python programs first. Even for dynamic reloading of modules, I usually just write External methods to do the job, instead of firing up the monitor. A more useful debuging tool would be some monitor where you can receive print message logs in real time. That would be great, especially if you have multiple thread problems. regards, Hung Jung _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: [Zope] Medusa Monitor
I know that, the stupid log file thingy. But you'll have to write an independent thread to display the log file (or peek the file manually each time), or implement some CString stuff to capture the file output (if that is possible). It'll be more fun if all this is already done, and the user can just tap into the monitor console screen (even remotely). A good monitor should actually display hit information, memory usage, etc, and preferably with charts, all in real time. Too much to ask? I don't think so. :) Hung Jung >From: Dieter Maurer <[EMAIL PROTECTED]> >To: "Hung Jung Lu" <[EMAIL PROTECTED]> >CC: [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] >Subject: Re: [Zope] Medusa Monitor >Date: Thu, 12 Oct 2000 23:47:35 +0200 (CEST) > >Hung Jung Lu writes: > > A more useful debuging tool would be some monitor where you can receive > > print message logs in real time.

Useless for debugging? I find it very useful and sometimes necessarybut I right all my products in python so maybe it is different for ZClass people. terry Hung Jung Lu wrote: > Thanks for the follow-ups on Medusa Monitor. > > But as I can see (after using Zope for 1.5 years, now), few people actually > use it.

As I understand it, the logging module can be customized to stuck its log into a variable in Zope itself, viewable through the web. You may search the list archive to find the corresponding post. Maybe, you find it, too, via zope.org. > It'll be more fun if all this is already done, and the user can just tap > into the monitor console screen (even remotely). > > A good monitor should actually display hit information, memory usage, etc, > and preferably with charts, all in real time.

Anderson Ami writes: > Anybody knows What is Medusa Monitor ? What it do ? How can I use it ? The Medusa monitor allows you to connect to a running Zope Server and get a Python interpreter in this context. With it, you can (in principle) analyse your Zope system. However, this way of debugging is probably only for experts. There is a document at zope.org (I forgot its name) that says a bit about this "monitor": search for "monitor".
