Background

Beaver provides an lightweight method for shipping local log files to Logstash. It does this using either redis, stdin, zeromq as the transport. This means you'll need a redis, stdin, zeromq input somewhere down the road to get the events.

Events are sent in logstash's json_event format. Options can also be set as environment variables.

Examples

Example 1: Listen to all files in the default path of /var/log on standard out:

beaver

Example 2: Sending logs from /var/log files to a redis list:

REDIS_URL="redis://localhost:6379/0" beaver -t redis

Example 3: Use environment variables to send logs from /var/log files to a redis list:

REDIS_URL="redis://localhost:6379/0" BEAVER_PATH="/var/log" BEAVER_TRANSPORT=redis beaver

Example 4: Zeromq listening on port 5556 (all interfaces):

ZEROMQ_ADDRESS="tcp://*:5556" beaver -m bind

# logstash config:
input { zeromq {
 type => 'shipper-input'
 mode => 'client'
 topology => 'pushpull'
 address => 'tcp://shipperhost:5556'
 } }
output { stdout { debug => true } }


Example 5: Zeromq connecting to remote port 5556 on indexer:

ZEROMQ_ADDRESS="tcp://indexer:5556" beaver -m connect

# logstash config:
input { zeromq {
 type => 'shipper-input'
 mode => 'server'
 topology => 'pushpull'
 address => 'tcp://*:5556'
 }}
output { stdout { debug => true } }
