The methods here control the Process Monitor which allow a programmer to capture
metrics for the current process. The metrics are the same counters as
captured by the PERFMON utility, but they are only captured for the current
process and stored in the process local memory. This ensures that it has
minimal effect on the rest of the system.
Application programmers can embed the methods in their code, so that the
Process Monitor can be enabled and metrics reported by user processes,
allowing them to analyze trouble spots on live systems.
Note that all of the counters are either 32 or 64-bit counters, according to the word length
of the platform, and follow the SNMP Counter32 and Counter64 semantics defined in RFC1442.
Application code which subtracts a previous value from the current value must take into account the possible
wrap around back to zero. All counters for a process may be initialized to zero using Clear().
Returns a comma-delimited list of all the Process Monitor metrics. These are in
the same order as the metric counters returned by the Report() method. Although the list
of metrics and the order of these metrics should be fairly static, it is possible
that new metrics might be added or the order changed for some reason in future
versions. Use this method to "name" the metrics when reporting them.
The metrics are the same as those reported by ^PERFMON, and the documentation for
PERFMON gives a brief description of each metric.
