Internally, derive works exactly 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. @@ -154,7 +154,7 @@ I defines the formula used to compute the PDPs of a COMPUTE data source from other data sources in the same . It is similar to defining a B argument for the graph command. Please refer to that manual page for a list and description of RPN operations supported. For -COMPUTE data sources, the following RPN operations are not supported: PREV, +COMPUTE data sources, the following RPN operations are not supported: COUNT, PREV, TIME, and LTIME. In addition, in defining the RPN expression, the COMPUTE data source may only refer to the names of data source listed previously in the create command. This is similar to the restriction that Bs must
