Performance Monitor SNA Adapter Counters Are Missing (190445)


The information in this article applies to:

  • Microsoft SNA Server 3.0
  • Microsoft SNA Server 4.0
This article was previously published under Q190445

SYMPTOMS

Performance Monitor doesn't show the SNA Server adapter counters even when SNA Server is started.

NOTE: The SNA Server service must be started in order for the SNA performance objects to appear within Windows NT performance monitor.

CAUSE

If SNA Server is installed into a directory name that contains spaces, the SNA Setup program fails to add SNA Server adapter object counters, regardless of the SNA Server link type being used.

RESOLUTION

Microsoft has confirmed this to be a problem in SNA Server version 4.0 and 4.0 SP1. This problem was corrected in the latest SNA Server version 4.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

WORKAROUND

On computers that do not show the Performance Monitor counters, you can try using the following procedure to get them installed. The following procedure can be used to unload and reload the Performance Monitor Counters for SNA Server and the TN3270 service:
  1. Open a command prompt on the Windows NT server where SNA Server is installed.
  2. Change to the snaroot\System directory (C:\SNA\SYSTEM, by default).
  3. Type the following at the command prompt and press ENTER to remove the SNA Server counters:

    unlodctr snaservr

  4. Type the following at the command prompt and press ENTER to remove the TN3270 counters:

    unlodctr tn3270

    NOTE: If the counters were correctly installed, these commands will return text similar to the following:

    Removing counter names and explain text for SERVICE NAME.
    Updating text for language 009.

    If the counters were not correctly installed, these commands will return text similar to the following:

    Counters for SERVICE NAME have not been installed yet.

  5. Type the following at the command prompt and press ENTER to install the SNA Server counters:

    lodctr snaperf.ini

  6. Type the following at the command prompt and press ENTER to install the TN3270 counters:

    lodctr tn3perf.ini

NOTE: The .ini files contain counters for several languages that may not be installed on the system. This will result in a large number of error messages scrolling across the Command Prompt window for each of the languages not installed. This does not have any adverse effect on the successful installation of the counters.
