log4r-sequel

Log4r outputter to a Sequel database handle

• usage
  • pre-built gem installation (stable)
  • from-source installation (latest)
  • demo
• supported databases
• notes

the de-facto standard library for logging in Ruby, log4r, works very well for a wide array of logging targets:

• STDOUT / STDERR
• file
• email
• syslog

and so on, but didn't have a way to output directly to a database - enter log4r-sequel

this project was inspired/motivated by the fact that chainsaw isn't supported on recent versions of OSX.

usage

pre-built gem installation (stable)

gem install log4r-sequel
