Orchestrator Logfiles

– March 15, 2011Posted in: Tools, Troubleshooting / Debugging

Orchestrator uses the log4j-mechanism (Version 1.2) for logging. The core-platform, custom scripting elements (via System.log()) and the Plugins log to the targets configured in the log4j.xml in %INSTALLDIR%\app-server\server\vmo\conf.

For a description of the possible log-targets view the original log4j-documentation:
http://logging.apache.org/log4j/1.2/manual.html

Nice examples for the configuration log4j.xml you can find on
http://wiki.apache.org/logging-log4j/Log4jXmlFormat

Additional there is a snmp-appender for log4j. So you can send snmp-traps for log-events as well. An example configuration:

Some books I found useful when working with vCO…
Steve Jin: VMware VI and vSphere SDK
Steve Jin ( www.doublecloud.org ) focus is on the VI Java Toolkit. However the books also includes a great general introduction of the vSphere API and lots of UML-diagrams of the API data model. Both is very useful when you develop vCO scripts interacting with vCenters

David Flanagan: JavaScript – The Definitive Guide
Since all the scripting elements are written in JavaScript, you need at least one book with a JavaScript-reference on your desk.
(Of course, you can find examples all over the web, but in most cases searching in the internet costs more time and distracts more than simply open the reference book on the marked site ).

Marijn Haverbeke: Eloquent JavaScript
If you are new to JavaScript, most of the books about it out there are do not fit for an vCO-guy because they contain too much web-related stuff.
An exceptional introduction to JavaScript NOT focussing on the web-stuff is "Eloquent JavaScript". The book is really good to read, and best of all: There is an online version available on http://eloquentjavascript.net which contains an interactive JavaScript console. So you can directly test the code examples online in your browser while you read:
The fastest way to learn JavaScript from scratch!
