The Collectd itself does not track values, it takes snapshot. But such tracking can be done by kernel or by application itself. For example, webserver can provide two metrics: "current connections count", which would be taken as snapshot (peak values between metering would be lost) and "number of requests/connections processed" (metric, tracked by application). In this example, the first metric value interesting intact, and second metric value interesting as a rate value. If you need to know min/max/average value between collectd measurements, that should be supported by the application and provided as a value which reset after measurement. -- Regards, Pavel mailto:pavel2...@ngs.ru _______________________________________________ collectd mailing list collectd@verplant.org http://mailman.verplant.org/listinfo/collectd
