Chuck, out of interest, when you say you use the gmetric interface, are you still doing XDR binary encoding for the core metrics, or are you having all the metrics as sets of strings (ala gmetric)?
kind regards, richard -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chuck Simmons Sent: 28 July 2006 20:22 To: ganglia-developers@lists.sourceforge.net Subject: Re: [Ganglia-developers] Ganglia-developers Digest, Vol 2, Issue 17 With respect to the discussions on gmond plugins and sample rates for /proc files... I use a slightly different approach than is being discussed. I ripped all (well, most) of the metric gathering code out of 'gmond'. I then implemented code that uses the 'gmetric' interface to publish metrics. [In some sense, I use 'gmetric' as the plug-in interface.] I organized the metric gathering code around /proc files. This is roughly equivalent to collection groups. The basic idea is to read in a /proc file, parse the entire contents into a set of metrics, and publish the metrics that need publishing. It's my belief that structuring the code to process a /proc file at a time (instead of processing a metric from a cached /proc file) reduces the number of lines of code. Additionally, this type of approach may be advantageous for handling variable length /proc files such as publishing network statistics per interface or disk I/O statistics per disk drive.
