Answers
Q: Can you recommend performance counters that I should monitor?
A:
It's hard to tell what YOUR specific needs for monitoring are, but there are some documents from Microsoft that suggest a number of performance counters to look for, and all these counters are available for PRTG and IPCheck through SNMP Helper Pro (and the Extensions).
Q: Why can't I access performance counters after installing SNMP Helper?
A: We have observed that in some cases, performance counter objects are not available to the Windows Performance Counter applet, and if the applet cannot see the performance counter objects, then neither can SNMP Helper. To reactivate disabled counters, we recommend you use the EXCTRLST.EXE utility available from Microsoft at http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/exctrlst-o.asp. This utility lets you select performance counters, and activate or deactivate them using a GUI interface. We have at times seen where counters were disabled (for no apparent reason), and upon activation, the counters were again available to the Performance Monitor applet, and subsequently to SNMP Helper.
