In order to monitor Cisco Express, you need to have BOTH collectors running. IRCXCOL is the main Cisco Express collector but the IRCXSCOL is that Pace collector that supplies the Summary record.
Edit the ‘PROGNOSIS Configuration’ and locate the SET RUN statements for these two processes and ensure they are set with ‘Y’.
SET RUN ( IRCXCOL.EXE, Y )
SET RUN ( IRCXSCOL.EXE, Y )
