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.
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
log_filename: falseConsider 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.
If log_filename is set to true then the filename is included in the tag. For example, new lines written to app1/stdout.log get sent to syslog tagged as app1/stdout.log.
Currently the priority and facility are hardcoded to INFO and user.
