At our company, we wrote something that checks the trace.log file to check the status of the current zope requests. The trace.log file records when a new network connection is opened, when a thread starts processing a request, when a thread is done publishing, and when it has finished writing. The tool continuously re-reads the end of the file looking for new data records and turns those into SNMP data for the number of active requests, the number of queued requests, and the average response time. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

I'm assuming you're on *nix of some flavor. First thing to do is use ps to see if there are any zope-related python processes running. For example: $ ps wax | grep python | grep ope On my gentoo workstation, I'm running both zope and zeo currently, so I get: 9609 ?S 0:05 /usr/local/bin/python /home/pw/z29soft/lib/python/Zope2/Startup/run.py -C /home/pw/z29inst/etc/zope.conf 9610 ?S 0:01 /usr/local/bin/python /home/pw/z29soft/lib/python/ZEO/runzeo.py -C /home/pw/z29inst/etc/zeo.conf If there are no processes, zope is obviously not running at all :) If there are processes but zope is not responding, first thing I would do is check the end of the zope event log and request log.

[Zope] Check Zope status
Hi All, We’re having a few problems with our Zope server, it seems to be crashed but were not sure whether it is actually crashed or merely waiting (a long time) for a response from LDAP to authenticate our users, which may be causing it to hang. Is there any tool we can use to test to see if Zope has actally crashed?
