Buffering and the PI message log

You can view the message log as follows:

• (PI Buffer Subsystem 4.3 or later only) Use Buffering Manager. In the dashboard, click the View messages link.

• Use PI System Management Tools. In the System Management Tools pane, click Operation > Message Log.

• Use PI Interface Configuration Utility. Click Tools > Log Files, then double-click the PIPC log file with the appropriate Date Last Modified. The PIPC log contains only messages written by PI interfaces.

  Messages related to PI Buffer Subsystem are likely to come from one of the following programs (shown in the Program column):

  Program	Description
  pibufss	PI Buffer Subsystem process messages
  The name of the buffered application	Messages from that application
  pinetmgr	Messages about connection to the server receiving buffered data
  pilogsrv	Messages that were originally in the PIPC log and were copied to the PI message log by the PIPC Log Server service. In the message body, look for pibufss or the name of the buffered interface. For example: I 28-Jul-14 15:26:45 pilogsrv (0) >> 28-Jul-14 15:26:45 pibufss.exe>PI-API Buffer Manager (19680) - serverA> Buffer status changed to disconnected.

If you have trouble identifying or viewing messages in the PI message log, see PI message log and 32-bit and 64-bit installations.

If PI Message Subsystem is not running, all messages go to the Windows Application Event Log. Use the Microsoft Event Viewer to look at Windows Event Logs.
