After installing SNMP Helper on a device I don't see any disk drive counters

Questa pagina anchora non esiste in Italiano. Confidiamo nella Vs. comprensione.

In some situations after installing SNMP Helper Freeware or Pro Edition on a machine you may not be able to see all disk related sensors (especially on Windows 2000).

On the machine that - when queried - does not show all disk data in the SNMP Helper sensorlist please perform the following steps:

1) Open an OS prompt
2) Type "diskperf -y" (omit the "")
3) Close the OS prompt
4) reboot the server
5) try again in PRTG

This enabled the disk counters if they are disabled.

Note: If your diskdrives are fault-tolerant you may need to use "diskperf -y -e"
