Beaver 26

Configuration File Options

Beaver can optionally get data from a configfile using the -c flag. This file is in ini format. Global configuration will be under the beaver stanza. The following are global beaver configuration keys with their respective meanings:

• rabbitmq_host: Defaults localhost. Host for RabbitMQ.

• rabbitmq_port: Defaults 5672. Port for RabbitMQ.

• rabbitmq_vhost: Default /

• rabbitmq_username: Default guest

• rabbitmq_password: Default guest

• rabbitmq_queue: Default logstash-queue.

• rabbitmq_exchange_type: Default direct.

• rabbitmq_exchange_durable: Default 0.

• rabbitmq_key: Default logstash-key.

• rabbitmq_exchange: Default logstash-exchange.

• redis_url: Default redis://localhost:6379/0. Redis URL

• redis_namespace: Default logstash:beaver. Redis key namespace

• udp_host: Default 127.0.0.1. UDP Host

• udp_port: Default 9999. UDP Port

• zeromq_address: Default tcp://localhost:2120. Zeromq URL

• zeromq_hwm: Default None. Zeromq HighWaterMark socket option

• zeromq_bind: Default bind. Whether to bind to zeromq host or simply connect

The following are used for instances when a TransportException is thrown - Transport dependent

• respawn_delay: Default 3. Initial respawn delay for exponential backoff

• max_failure: Default 7. Max failures before exponential backoff terminates

The following configuration keys are for building an SSH Tunnel that can be used to proxy from the current host to a desired server. This proxy is torn down when Beaver halts in all cases.

• ssh_key_file: Default None. Full path to id_rsa key file

• ssh_tunnel: Default None. SSH Tunnel in the format user@host:port

• ssh_tunnel_port: Default None. Local port for SSH Tunnel

• ssh_remote_host: Default None. Remote host to connect to within SSH Tunnel

• ssh_remote_port: Default None. Remote port to connect to within SSH Tunnel

The following can also be passed via argparse. Argparse will override all options in the configfile, when specified.

• format: Default json. Options [ json, msgpack, string ]. Format to use when sending to transport

• files: Default files. Space-separated list of files to tail. (Comma separated if specified in the config file)

• path: Default /var/log. Path glob to tail.

• transport: Default stdout. Transport to use when log changes are detected

• fqdn: Default False. Whether to use the machine’s FQDN in transport output

• hostname: Default None. Manually specified hostname

Examples

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

beaver

Example 2: Listen to all files in the default path of /var/log on standard out with msgpack:

beaver --format msgpack

Example 3: Listen to all files in the default path of /var/log on standard out as a string:

beaver --format string

Example 4: Sending logs from /var/log files to a redis list:

# /etc/beaver.conf
[beaver]
redis_url: redis://localhost:6379/0

# From the commandline
beaver  -c /etc/beaver.conf -t redis

Example 5: Use environment variables to send logs from /var/log files to a redis list:

# /etc/beaver.conf
[beaver]
redis_url: redis://localhost:6379/0

# From the commandline
beaver  -c /etc/beaver.conf -p '/var/log' -t redis

Example 6: Zeromq listening on port 5556 (all interfaces):

# /etc/beaver.conf
[beaver]
zeromq_address: tcp://*:5556

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

# From the commandline
beaver  -c /etc/beaver.conf -m bind -t zmq

Example 7: Zeromq connecting to remote port 5556 on indexer:

# /etc/beaver.conf
[beaver]
zeromq_address: tcp://indexer:5556

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

# on the commandline
beaver -c /etc/beaver.conf -m connect -t zmq

Example 8: Real-world usage of Redis as a transport:

# in /etc/hosts
192.168.0.10 redis-internal

# /etc/beaver.conf
[beaver]
redis_url: redis://redis-internal:6379/0
redis_namespace: app:unmappable

# logstash indexer config:
input {
  redis {
    host => 'redis-internal'
    data_type => 'list'
    key => 'app:unmappable'
    type => 'app:unmappable'
  }
}
output { stdout { debug => true } }

# From the commandline
beaver -c /etc/beaver.conf -f /var/log/unmappable.log -t redis

As you can see, beaver is pretty flexible as to how you can use/abuse it in production.

Example 9: RabbitMQ connecting to defaults on remote broker:

# /etc/beaver.conf
[beaver]
rabbitmq_host: 10.0.0.1

# logstash indexer config:
input { amqp {
    name => 'logstash-queue'
    type => 'direct'
    host => '10.0.0.1'
    exchange => 'logstash-exchange'
    key => 'logstash-key'
    exclusive => false
    durable => false
    auto_delete => false
  }
}
output { stdout { debug => true } }

# From the commandline
beaver -c /etc/beaver.conf -t rabbitmq

Example 10: Read config from config.ini and put to stdout:

# /etc/beaver.conf:
[/tmp/somefile]
type: mytype
tags: tag1,tag2
add_field: fieldname1,fieldvalue1[,fieldname2,fieldvalue2, ...]

[/var/log/*log]
type: syslog
tags: sys

[/var/log/{secure,messages}.log]
type: syslog
tags: sys

# From the commandline
beaver -c /etc/beaver.conf -t stdout

Example 11: UDP transport:

# /etc/beaver.conf
[beaver]
udp_host: 127.0.0.1
udp_port: 9999

# logstash indexer config:
input {
  udp {
    type => 'shipper-input'
    host => '127.0.0.1'
    port => '9999'
  }
}
output { stdout { debug => true } }

# From the commandline
beaver -c /etc/beaver.conf -t udp

• Added logging on connection exception. [Thomas Morse]

• Add ‘–format raw’ to pass through input unchanged. [Stephen Sugden]

• Fix string & null formatters in beaver.transport. [Stephen Sugden]

  the inline definitions were expecting a self parameter, which is not passed when you assign a function to an attribute on an object instance.

• Copy the readme over to avoid pypi packaging warnings. [Jose Diaz- Gonzalez]

• Implement fully recursive file globing. [Brian L. Troutwine]

  Python’s base glob.iglob does not operate as if globstar were in effect. To explain, let’s say I have an erlang application with lager logs to

  /var/log/erl_app/lags.log /var/log/erl_app/console/YEAR_MONTH_DAY.log

  and webmachine logs to

  /var/log/erl_app/webmachine/access/YEAR_MONTH_DAY.log

  Prior to this commit, when configured with the path /var/log/**/*.log all webmachine logs would be ignored by beaver. This is no longer the case, to an arbitrary depth.

19 (2013-01-01)

16 (2012-12-27)

• Specify a max queue size of 100 to limit overrunning memory. [Jose Diaz-Gonzalez]

• Use multiprocessing for handling larger queue sizes. [Jose Diaz- Gonzalez]

  Previously there were issues where files that were updated frequently such as varnish or server logs would overwhelm the naive implementation of file.readlines() within Beaver. This would cause Beaver to slowly read larger and larger portions of a file before processing any of the lines, eventually causing Beaver to take forever to process log lines.

  This patch adds the ability to use an internal work queue for log lines. Whenever file.readlines() is called, the lines are placed in the queue, which is shared with a child process. The child process creates its own transport, allowing us to potentially create a Process Pool in the future to handle a larger queue size.

  Note that the limitation of file.readlines() reading in too many lines is still in existence, and may continue to cause issues for certain log files.

• Add default redis_password to BeaverConfig class. [Jose Diaz-Gonzalez]

• Add the ability to daemonize. Closes #79. [Jose Diaz-Gonzalez]

• Pass around a logger instance to all transports. [Jose Diaz-Gonzalez]

• Revert “Added a lightweight Event class” [Jose Diaz-Gonzalez]

  After deliberation, beaver is meant to be “light weight”. Lets leave the heavy hitting to the big boys.

  This reverts commit 1619d33ef4803c3fe910cf4ff197d0dd0039d2eb.

• Added a lightweight Event class. [Jose Diaz-Gonzalez]

  This class’s sole responsibility will be the processing of a given line as an event. It’s future goal will be to act as a lightweight implementation of the filter system within Logstash

• Remove argparse requirement for python 2.7 and above. [Jose Diaz- Gonzalez]

15 (2012-12-25)

• Pull argument parsing out of beaver __init__.py. [Jose Diaz-Gonzalez]

• Move app-running into __init__.py. [Jose Diaz-Gonzalez]

• Standardize on _parse() as method for parsing config. [Jose Diaz- Gonzalez]

• Automatically parse the path config option. [Jose Diaz-Gonzalez]

• Remove extensions argument on Worker class. [Jose Diaz-Gonzalez]

  This argument was only used when no globs were specified in a config file. Since it is not configurable, there is no sense leaving around the extra logic.

• Remove extra callback invocation on readlines. [Jose Diaz-Gonzalez]

• Remove extra file_config module. [Jose Diaz-Gonzalez]

• General code reorganization. [Jose Diaz-Gonzalez]

  Move both BeaverConfig and FileConfig into a single class

  Consolidated run_worker code with code in beaver binary file. This will create a clearer path for Exception handling, as it is now the responsibility of the calling class, allowing us to remove duplicative exception handling code.

  Added docstrings to many fuctions and methods

  Moved extra configuration and setup code to beaver.utils module. In many cases, code was added hastily before.

  Made many logger calls debug as opposed to info. The info level should be generally reserved for instances where files are watched, unwatched, or some change in the file state has occurred.

• Remove duplicative and old beaver instructions from binary. [Jose Diaz-Gonzalez]

• Remove unnecessary passing of ssh_tunnel subprocess. [Jose Diaz- Gonzalez]

• Added docstrings to ssh_tunnel module. [Jose Diaz-Gonzalez]

• Follow convention of underscore for object properties. [Jose Diaz- Gonzalez]

• Follow convention of underscore for object properties. [Jose Diaz- Gonzalez]

• Added a NullFormatter. [Jose Diaz-Gonzalez]

  Useful for cases where we do not want any extra overhead on message formatting

• Refactored message formatting in base Transport class. [Jose Diaz- Gonzalez]

  We now use a _formatter property on the Transport class which will properly process the message for output as the user expects.

  In the case of string output, we define a custom formatter using an anonymous function and specify that as the formatter.

• Moved create_transport to transport module. [Jose Diaz-Gonzalez]

• Moved create_ssh_tunnel to ssh_tunnel module. [Jose Diaz-Gonzalez]

• Fixed order of beaver_config and file_config in args. [Jose Diaz- Gonzalez]

• Reduce overhead of parsing configuration for globs and files. [Jose Diaz-Gonzalez]

• Removed ordereddict dependency. [Jose Diaz-Gonzalez]

• Do not output info level when outputing version. [Jose Diaz-Gonzalez]

• Allow usage of ujson >= 1.19. Closes #76. [Jose Diaz-Gonzalez]

14 (2012-12-18)

• Removed erroneous redundant code. [Jose Diaz-Gonzalez]

• Workaround for differing iteration implementation in Python 2.6. [Jose Diaz-Gonzalez]

• Properly detect non-linux platforms. [Jose Diaz-Gonzalez]

• Improve Python 2.6 support. [Jose Diaz-Gonzalez]

• Fix broken python readme. [Jose Diaz-Gonzalez]

13 (2012-12-17)

• Fixed certain environment variables. [Jose Diaz-Gonzalez]

• SSH Tunnel Support. [Jose Diaz-Gonzalez]

  This code should allow us to create an ssh tunnel between two distinct servers for the purposes of sending and receiving data.

  This is useful in certain cases where you would otherwise need to whitelist in your Firewall or iptables setup, such as when running in two different regions on AWS.

• Allow for initial connection lag. Helpful when waiting for an SSH proxy to connect. [Jose Diaz-Gonzalez]

• Fix issue where certain config defaults were of an improper value. [Jose Diaz-Gonzalez]

• Allow specifying host via flag. Closes #70. [Jose Diaz-Gonzalez]

12 (2012-12-17)

• Reload tailed files on non-linux platforms. [Jose Diaz-Gonzalez]

  Python has an issue on OS X were the underlying C implementation of file.read() caches the EOF, therefore causing readlines() to only work once. This happens to also fail miserably when you are seeking to the end before calling readlines.

  This fix solves the issue by constantly re reading the files changed.

  Note that this also causes debug mode to be very noisy on OS X. We all have to make sacrifices…

• Deprecate all environment variables. [Jose Diaz-Gonzalez]

  This shifts configuration management into the BeaverConfig class. Note that we currently throw a warning if you are using environment variables.

  Refs #72 Closes #60

• Warn when using deprecated ENV variables for configuration. Refs #72. [Jose Diaz-Gonzalez]

• Minor changes for PEP8 conformance. [Jose Diaz-Gonzalez]

11 (2012-12-16)

• Add optional support for socket.getfqdn. [Jeremy Kitchen]

  For my setup I need to have the fqdn used at all times since my hostnames are the same but the environment (among other things) is found in the rest of the FQDN.

  Since just changing socket.gethostname to socket.getfqdn has lots of potential for breakage, and socket.gethostname doesn’t always return an FQDN, it’s now an option to explicitly always use the fqdn.

  Fixes #68

• Check for log file truncation fixes #55. [Jeremy Kitchen]

  This adds a simple check for log file truncation and resets the watch when detected.

  There do exist 2 race conditions here: 1. Any log data written prior to truncation which beaver has not yet read and processed is lost. Nothing we can do about that. 2. Should the file be truncated, rewritten, and end up being larger than the original file during the sleep interval, beaver won’t detect this. After some experimentation, this behavior also exists in GNU tail, so I’m going to call this a “don’t do that then” bug :)

  Additionally, the files beaver will most likely be called upon to watch which may be truncated are generally going to be large enough and slow filling enough that this won’t crop up in the wild.

• Add a version number to beaver. [Jose Diaz-Gonzalez]

10 (2012-12-15)
