Technical Tips – Shadowbase log information at a glance

Updated: Dec 29, 2022

by: Tom S.


Environment: Shadowbase is running on both Production and DR systems.

Goal: To be able to have a comprehensive view of the SB log activities on both systems.


  • TIC LogWatch – Captures EMS log messages and look for SB events to capture. Send captured events on DR system via TCP/IP to Production System

  • TIC IPLogger – TCP/IP Server to accept incoming socket messages and log to the same file as Production SB event logs.

  • TeleMail – Take log data and HTML code to generate HTML email

  • Custom COBOL program


  • Below is what we built with LogWatch, IPLogger  plus a COBOL program.

  • This brings all EMS messages together from both systems in a single error log.

  • The RED text are errors.  The light grey background is from Production and the Medium grey is from the DR machine.

  • The events indicate significant time passage which means something new happened.

  • The line numbers down the side make it easy to speak over the phone with Gravic support when referencing a message.

  • The START and STOP are hardcoded displays based on AUDMON going up or down.  It makes it easier to read.

Result:  A daily email that reports all the SB activities in an easy-to-understand format for Operations
