I think you're confusing ABSOLUTE and DERIVE. What you describe is the ABSOLUTE data source type. The DERIVE data source type is like a counter, except that it can also produce a negative delta (which isn't possible using a COUNTER). In the documentation: " Internally, derive works exaclty like COUNTER but without overflow checks. So if your counter does not reset at 32 or 64 bit you might want to use DERIVE and combine it with a MIN value of 0. " Random resets are one example of counters that don't reset at 2^32 or 2^64. Don't forget the MIN value ... -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
