Correct, gmetric will the send your desired metric value and its attributes to gmetad.
If the OS or application only provides the metric as a counter but you want them visualized as a gauge, then it is on you to calculate the delta *and* rate of occurrence over time. The example scripts from Dr. Perzl are a good starting point for both, though I had to tweak the algorithm to fit my needs. -----Original Message----- From: Silver, Jonathan [mailto:jonathan.sil...@unify.com] Sent: Monday, August 04, 2014 10:44 AM To: Khrist Hansen; 'Ganglia' Subject: RE: [Ganglia-general] Is there a way to Display deltas for metrics Thanks, but gmetric (I thought) was for the collection of metrics into ganglia. The metrics are already being collected but they are the sum since day 1. I guess that I could create a new metric by running a local script, get the latest 2 values from rrds, compute the difference and set that as the new value for the new metric (added using gmetric), but that is a lot of overhead. Did I miss-understand something? -----Original Message----- From: Khrist Hansen [mailto:khrist.han...@gmail.com] Sent: Monday, August 04, 2014 11:39 AM To: Silver, Jonathan; 'Ganglia' Subject: RE: [Ganglia-general] Is there a way to Display deltas for metrics I use gmetric from a script scheduled to run every minute via cron. Check 'man gmetric' for syntax, and there are example scripts here: http://www.perzl.org/ganglia/devicespecific.html Hope that helps, Khrist -----Original Message----- From: Silver, Jonathan [mailto:jonathan.sil...@unify.com] Sent: Monday, August 04, 2014 10:18 AM To: Ganglia Subject: [Ganglia-general] Is there a way to Display deltas for metrics Some of the metrics that we are collecting are totals since the system rebooted. That is not very interesting and it becomes a huge number that shows (percentage-wise) little change over time. Is there some way to change ganglia to display the change of this metric instead of it value without changing the collector itself?
