Erlang
Papertrail can accept logs from any Erlang (BEAM) app, with or without the
lager
logging library.
Send log file with remote_syslog2
Configure your Erlang app to log to a file as usual, then transmit the log file to Papertrail using remote_syslog2. This does not require any modifications to the app.
Send events from Erlang app
Alternatively, your app can send a log message directly to Papertrail using the remote syslog protocol.
To do this, add schlagert/syslog to
the app and point it at Papertrail. See
Add Systems for dest_host
and
dest_port
log destination values. Use either protocol RFC; if in doubt,
choose rfc5424
.
Since schlagert/syslog
is emitting UDP, which is inherently connection-less,
the write calls are non-blocking.
Send events with lager library and system syslog
Erlang applications that already use the lager
logging library can
configure it to also log to syslog. See lager_syslog, which will send logs
to a syslog daemon running on the local host (such as rsyslog or syslog-ng).
Follow standard setup to
configure the syslog daemon to forward to Papertrail.
