thsetz / ps.herald

Introduction

The Herald package provides three tools usable to monitor the behaviour of distributed applications

Herald's functionality is based on the Basic class, defined in the ps.basic package.

The Basic class enhances/uses the standard python logging package - especially the ability to log messages to a stream-socket.

This package adds mechanisms to:

• put these messages into a central database (bridge)
• route/bridge these messages to additional destinations (bridge)
• display in a web-server (herald)
• take actions on special messages (neelix)
• take actions on lost system heartbeat (neelix)
