Send Data to a Separate Log File
Logging data throughout our openHAB programming & examining openHAB's logs are helpful to our debugging.
By default, changes in item states, warnings, errors, & data we generate with logInfo() are writen to openhab.log & events.log in openHAB's log folders. For viewing, we can load these .log files into a text editor like Notepad++. We can also view their scrolling entries in real time, by entering log:tail in openHAB's Karaf console. If we generate multiple log entries, this can grow cumbersome & confusing.
To debug certain projects or to record information we may want/need later, we might set openHAB to log similar-topic data in a log file other than openhab.log or events.log.
A rule statement such as logInfo("Irrigation", "Valves ON") has the potential to make a time-stamped entry in a separate Irrigation.log file. However, some setup is required first. Otherwise, the log entry will just show up in openhab.log.
The following is how I did it for openHAB 2.5.0.M1 which may relate to other recent versions. I adapted what I found here (See the reply after "Try:").
