greg bruno’s python class v2.0 released!
Posted by Matt Massie in Releases on March 22, 2002
The command-line client (/usr/sbin/ganglia) is a small utility which is best used as an example — guiding the development of other python-based ganglia tools. The command-line client instantiates the ganglia python class (Gang). ‘Gang’ (/usr/lib/python1.5/site-packages/gmon/ganglia.py) is where all the “heavy-lifting” occurs, as it contains the methods to attach to a local gmond server and parse gmond’s XML output. Other methods are included that output specific metrics and display a help message (by dynamically examining the metrics in the XML output!).

- Added XML_ParserFree() call to gexec_cluster() lib call to plug up memory leak
- Modified ./gmond/server.c to prevent crashes under heavy stress conditions
- Added fclose() calls to gexec_cluster() to plug a memory leak
- Added gexec_cluster_free() call to gstat for good measure
Monitoring Core v2.2.0 Released!
Posted by Matt Massie in Releases on March 18, 2002
- Preston Smith patched a wrong sysctl to get free memory for freebsd machines
- Added mute and deaf mode for gmond
- Created a new ganglia-monitor-core-lib distribution for the libganglia library. Ganglia has the start of a C API now.
- Moved all the documentation to DocBook, added much more information and updated/removed what was there. Output docs to ./docs directory of the distribution in both HTML and PDF form. Also installed Doxygen to document libganglia.
- Add the Ganglia Status Tool (gstat) which allows you to check the status of your cluster from the commandline. Hosts are sorted with least-loaded nodes at the top of the list.
- Removed the need for the POSIX mutex in pre_process_node() allowing for faster processing of incoming multicast data
- Changed gmond to not count itself as a running process when reporting the number of running processes.
- Doc Schneider changed the way ganglia builds RPMs to support non-root builds as suggested by an anonymous SourceForge user
Documentation Updated
Posted by Matt Massie in Announcements on March 14, 2002
I’ve put all the Ganglia documentation in DocBook format in order to index and organize the ganglia documentation and also create a manual in PDF which can easily be printed. The documentation is incomplete but I’m updating it daily.
