About

Blackbox will tail all files in sub-directories of a specified source_dir, and forward any new lines to a syslog server.

This is currently used in syslog-release and windows-syslog-release.

Usage

blackbox -config config.yml

The configuration file schema is as follows:

hostname: this-host

syslog:
  destination:
    transport: udp
    address: logs.example.com:1234

  source_dir: /path/to/log-dir

Consider the case where log-dir has the following structure:

/path/to/log-dir
|-- app1
|   |-- stdout.log
|   `-- stderr.log
`-- app2
    |-- foo.log
    `-- bar.log

Any new lines written to app1/stdout.log and app1/stderr.log get sent to syslog tagged as app1, while new lines written to app2/foo.log and app2/bar.log get sent to syslog tagged as app2.

Currently the priority and facility are hardcoded to INFO and user.
