File Content Sensor (Line Feed vs Carriage Return)



I am attempting to monitor a tomcat log file (catalina.out) running on a linux server. When using the File Content Sensor and searching for a simple string such as "error" PRTG returns the entire log file in the message, not just the line it occurred on (the goal). When testing with a file created in windows it returns the proper single line.

This leads me to presume that PRTG is expecting a carriage return in the file and not linux line feed. Short of converting the log file before scanning can prtg work with line feed?

Thanks everyone!

I opened a ticket with development to take a look into seeing if this sensor can be changed to allow for Linux line breaks. I'll post the results here.

Unix line breaks were integrated a month ago just to let you know.
