Log.io, set latest log from forever automatically

Question

I use Forever to automatically restart my app in case of problems. Recently I found out a really nice app to monitor different logs in my server from a browser, which is log.io.

Log.io allows me to set log files to monitor, for example:

logStreams: { 
  apache: [ "/var/log/apache2/access.log", "/var/log/apache2/error.log" ] 
},

For apache it works like a charm, because the file name is always the same. But forever at each restart of my app creates a totally new file name ([a-zA-Z0-9-_]{4}.log).

Is there a way to set a static log file name for forever, or to dynamically set the latest log file in config of log.io?

Which method would you advise?

Answer 1

From the forever documentation, you can define a forever log file with the following forever options.

options:
-l  LOGFILE      Logs the forever output to LOGFILE
-o  OUTFILE      Logs stdout from child script to OUTFILE
-e  ERRFILE      Logs stderr from child script to ERRFILE

so you would do something like this:

forever start -l /path/to/log/forever.log -o /path/to/log/myapp.log -e /path/to/log/myapp_error.log

you can then configure your log.io harvester

logStreams: { 
    myapp: [ "/path/to/log/myapp.log", "/path/to/log/myapp_error.log", "/path/to/log/forever.log" ] 
},
