This article applies to:

• WebMarshal 6.X or 7.X
• Windows operating system international versions

Symptoms:

• No data displays in WebMarshal dashboard
• Errors in the WebMarshal Controller log: Failed to open performance data, retrying in 5 seconds

Causes:

• WebMarshal retrieves system Performance Counter data by text name. This is the standard technique.
• WebMarshal uses the following system Performance Counters:
  • \Processor(_Total)\% Processor Time
  • \Memory\% Committed Bytes In Use
  • \[install disk drive name]\% Free Space
• When Windows is installed using an operating system version other than English, the counter names differ.

Resolution:

• Verify that the WebMarshal performance monitor dll is successfully registered.
• To ensure that WebMarshal can retrieve Performance Counter data, install WebMarshal only on an English language version of Windows.
• Changing Windows regional settings or input language (Language Bar) does not resolve or cause this issue.
• Use of the Windows Multilingual User Interface (MUI) optional add-in to set the interface language could affect this issue. Microsoft states that Windows 2003 Performance Counters are MUI aware.

Notes:

Trustwave is researching improvements to the counter retrieval functionality.
