need a universal identifier to filter all lines from the server logs related to a specific IL run

We urgently need a universal identifier to filter all lines from the server logs related to a specific IL run.

When something goes wrong with an IL run (which has been failing more frequently in recent versions like 14.0 or 14.6 due to timeout settings), we need to grep the Spotfire Server's logs folder to find all the information related to this IL run across the following log files:

C:\spotfire\spotfireserver\14.6.3\tomcat\logs\server.log

C:\spotfire\spotfireserver\14.6.3\tomcat\logs\informationservices\server.log

C:\spotfire\spotfireserver\14.6.3\tomcat\logs\informationservices\sql.log
