PandaLogger

The Panda logger provides client and server components for a logging system by which Panda services can register incidents for central logging, users can inspect logging records through a web interface (PandaMonitor), and diagnostics and log analysis can be performed on logging records (in the PandaMonitor).

The logger is based on the standard Python logging module.

Logger client interface

The logger client is implemented as a small extension of the http handler offered by the python logging module. See PandaLogger.py for the code and testlog.py for a usage example.

Logger service

The logger service runs off of the same Apache server as the monitor. The logger service receives http logging messages from clients and registers them in a logging DB in the PanDA database. See loggerd.py

Logger web interface

The web interface for the logger is part of the PanDA monitor at panda.cern.ch.
