  • CitectSCADA x.xx
Summary:
 When running CitectSCADA in Multi-process and analysing the statistics through perfmon, you will notice that when you want to add a "Citect" counter, each Citect process is on separate instances listed as Citect32, Citect32#1, Citect32#2, ...., etc. The following diagram shows what you will encounter in perfmon:


It is hard for us to identify which Citect process corresponds to which perfmon process instance displayed (i.e is Citect32#1 points to IOServer, Alarm, Report, or Trend process).

Is there a way around it so that it is easier to identify which Citect process that the instances are pointing to?


Solution:
 There is a way to display Process ID (PID) of each process in perfmon during counter selection. It involves a change in registry settings as follows:

  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PerfProc\Performance
  3. On the Edit menu, click New, and then click DWORD Value.
  4. Right-click New Value #1, click Rename, and then type ProcessNameFormat to name the new value.
  5. Right-click ProcessNameFormat, and then click Modify.
  6. In the Data value box, type one of the following values, and then click OK:
    • 1: Disables PID data. This value is the default value.
    • 2: Enables PID data.
  7. Exit Registry Editor.

Since in Citect Runtime Manager, we can determine unique PID for each Citect processes, we can match it easily when perfmon displays the PID in the counter selection.
