C.2 Ganglia Metrics

Not all Ganglia metrics are suitable for aggregation, such as those of “String” type. By default, only the 24 metrics listed in the following table are supported (either of type “Real” or type “Integer”):

C.2.1 Limitations

The monitoring function of PlateSpin Orchestrate does not display some of the metrics of monitored Windows servers. The non-displayed metrics include:

  • cpu_aidle

  • cpu_nice

  • cpu_wio

  • disk_free

  • disk_total

  • load_fifteen

  • load_five

  • load_one

  • mem_buffers

  • mem_cached

  • mem_shared

  • part_max_used

  • proc_run

In addition to these non-displaying metrics, two others show incorrect values in resource facts:

  • os_name

  • os_release

In the Monitoring Web interface and in the VM Client, the absence of these metrics appears as a missing page. In the Development Client, the monitored resource’s fact values corresponding to these metrics all show as zero (0), except for the os_name and os_release metrics, which display incorrect values.

This is a known issue that exists for the Ganglia monitoring system on Windows. For more information, see the SourceForge mailing list discussion.
