Abstract
The present invention is directed towards “skip” and “differential” recording techniques for recording values of network parameter to a log in a lossless manner while reducing storage resources used to record such values. The counter monitor of the present invention monitors and records values of counters at time intervals to generate a counter log provided via temporary or permanent storage. The counter monitor compares a reading of the value of the counter to a previously obtained value of the counter. If the value of the counter has not changed, the counter monitor records only the timestamp to the counter log, thereby “skipping” the recording of the unchanged value. If there is any change in the value of the counter, then the change in value of the counter, i.e., a “differential” value, along with the timestamp is stored in the counters log. To further reduce storage resource usage, the counter monitor also stores changes to the timestamps as differential changes in time values.
