space-separated filelist to watch. Overrides --path
argument

log transport method
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 } }
Todo
Use python threading + subprocess in order to support usage of yield across all operating systems
Fix usage on non-linux platforms - file.readline() does not work as expected on OS X. See above for potential solution
More transports
~Separate tranports into different files so that individual transport requirements are not required on all installations (libzmq)~
~Create a python package~
Ability to specify files, tags, and other metadata within a configuration file
