SystemEDGE provides access to performance counters in the performance registry by specifying the object and counter names. For instance, the object NWLink NetBIOS and counter Bytes Total/sec identifies the NetBIOS byte-counter statistic.
When using performance counters, you must interpret the data carefully. There are at least 27 different counter types in Windows. Most counters do not actually report the data in the format that you assume based on the name of the counter. Instead, most values are raw counters that require you to do post-processing; for example, dividing the difference of two samples by the elapsed time. If you see a counter name like Bytes Total/sec, the data you are really getting is a raw counter that can be used to calculate this rate.
Familiarize yourself with Windows Performance counters before using this feature. For more information, refer to the section on optimizing Windows in the Windows Resource Kit.
The following list matches the 4-byte performance data types that SystemEDGE supports with the preferred SNMP types:
Counter or integer
Counter, integer, or gauge

The following list matches the 8-byte performance data types that SystemEDGE supports with the preferred SNMP types. Because SNMPv1 supports only 4-byte values, agent returns only the least significant 4-bytes of data.
