Re: [Ganglia-general] on metric handler

[Vladimir Vuksan]

One of the approaches is to "cache" the results. For example this module has a method get_metrics https://github.com/ganglia/gmond_python_modules/blob/master/varnish/python_modules/varnish.py#L50 That will "cache" the info for few seconds. Hope that helps Vladimir On 01/20/2015 02:51 PM, Oliver wrote: hi all, I am a newbie on Ganglia and have a rather basic question: Say I want to define a handler that will collect three metrics (timestamp, read_bytes, write_bytes): all three metrics are from a single /proc entry, and it ONLY makes sense when three measures are looked together at some instant time t. Since the call back is written in such way that it seems each metric will be polled individually, there seems no such guarantee that the trio will be treated as group. Am I on the wrong track here? what's the appropriate way to approach it? Best, Oliver ------------------------------------------------------------------------------ New Year. New Location.
