Suppose server has drive C, D and S, and only C drive has lower than 5% free disk space

In Argent AT, the Event message will look like following:

LogicalDisk (C:)\%Free Space = 4.7 (< 5)

In Argent XT, the Event message will look like following:

The most significant difference is that Argent AT only lists out the drive that breaks the Rule while Argent XT lists out all the drives discovered by the system, no matter the drive breaks the Rule or not

Technical Background

New COMMON registry HKLM\Software\Argent\COMMON\USE_XT_PERF_EVENT_MSG_FORMAT (DWORD) is implemented to provide the backward compatibility

The default value is 0

When the boolean value is 1, the Argent XT compatible format is used

In other words, all performance instances should be included in the Event message

Resolution

Upgrade to Argent AT 3.1A-1504-T5 or later
