... what he said. rrdtool last This gives the timestamp of the latest PDP (after rate calculation and normalisation) rrdtool lastupdate This gives the timestamp and values of the RAW last update, BEFORE rate calculation and normalisation. rrdtool fetch This pulls out the timestamps and CDP values from the specified RRA, so AFTER rate calculation, normalisation and Consolidation. rrdtool updatev This updates the RRD with the supplied samples, and returns any CDP being written to RRA; so AFTER rate calculation, normalisation and consolidation. It may return zero or more CDP depending on how long it has been since your last update. Steve Steve Shipway [email protected]
