Introduction

See the doc of http://pypi.python.org/pypi/five.z2monitor

Use zc.monitor and additional plugins to fetch probes via another thread than the one defined in Zope.

Once the instance is running zc.monitor thread listen to another port (127.0.0.1:8888 in this buildout). You can query values using simple python script or nc.

Example:

echo ‘uptime’ | nc -i 1 localhost 8888

Or (when instance is up):

bin/instance monitor stats
