Description

Read events from a Jms Broker. Supports both Jms Queues and Topics.

For more information about Jms, see https://javaee.github.io/tutorial/jms-concepts.html. For more information about the Ruby Gem used, see http://github.com/reidmorrison/jruby-jms.

JMS configurations can be done either entirely in the Logstash configuration file, or in a mixture of the Logstash configuration file, and a specified yaml file. Simple configurations that do not need to make calls to implementation specific methods on the connection factory can be specified entirely in the Logstash configuration, whereas more complex configurations, should also use the combination of yaml file and Logstash configuration.

Sample Configuration using Logstash Configuration Only

Configurations can be configured either entirely in Logstash configuration, or via a combination of Logstash configuration and yaml file, which can be useful for sharing similar configurations across multiple inputs and outputs. The JMS plugin can also be configured using JNDI if desired.

Jar files

In order to communicate with a JMS broker, the plugin must load the jar files necessary for each client type. This can be set in the yaml file, or in the main configuration if a yaml file is not necessary. The require_jars setting should include the full path for each jar file required for the client. Eg

Logstash configuration

 input {
    jms {
              :
              [snip]
         require_jars => ['/usr/share/jms/commons-lang-2.6.jar',
                          '/usr/share/jms/sol-jms-10.5.0.jar',
                          '/usr/share/jms/geronimo-jms_1.1_spec-1.1.1.jar',
                          '/usr/share/jms/commons-lang-2.6.jar']
    }
 }

Troubleshooting

This section includes some common issues that a user may have when integrating this plugin with their JMS provider.

Missing Jar files

The most common issue is missing jar files, which may be jar files provided by the JMS vendor, or jar files that the JMS vendor requires to run. This issue can manifest in different ways, depending on where the missing jar file is discovered.

Example log output:

  Failed to load JMS Connection, likely because a JMS Provider is not on the Logstash classpath or correctly
  specified by the plugin's `require_jars` directive
  {:exception=>"cannot load Java class javax.jms.DeliveryMode"
  JMS Consumer Died {:exception=>"Java::JavaxNaming::NoInitialContextException",
                     :exception_message=>"Cannot instantiate class:"
  warning: thread "[main]<jms" terminated with exception (report_on_exception is true):
  java.lang.NoClassDefFoundError: org/apache/commons/lang/exception/NestableException
  JMS Consumer Died {:exception=>"Java::JavaxJms::JMSException", :exception_message=>"io/netty/channel/epoll/Epoll",
  :root_cause=>{:exception=>"Java::JavaLang::NoClassDefFoundError", :exception_message=>"io/netty/channel/epoll/Epoll"}

If any of these issues occur, check the list of require_jars in either the Logstash configuration or yaml configuration files.

Setting System Properties

Many JMS providers allow or expect System properties to be set to configure certain properties when using JMS, for example, the Apache qpid JMS client allows the connection factory lookup to be stored there, and the Solace JMS client allows many properties, such as number of connection retries to be set as System properties. Any system properties that are set should be set in the Logstash jvm.options file.

Multiple JMS inputs/outputs in the same Logstash process

The use of multiple JMS consumers and producers in the same Logstash process is unsupported if:

  • System properties need to be different for any of the consumers/producers
  • Different keystores or truststores are required for any of the consumers/producers

Message Selectors unexpectedly filtering out all messages

Incorrect message selector syntax can have two effects - either the syntax is incorrect and the selector parser from the JMS provider will throw an exception causing the plugin to fail OR the syntax will be accepted, but the messages will be silently dropped - this can happen with incorrect quoting of string properties in the selector definition. All selector definitions must be double quoted in the Logstash configuration file, and string property values must be single quoted, and numeric property values not quoted at all.

Jms Input Configuration Options

This plugin supports the following configuration options plus the Common Options described later.

Also see Common Options for a list of options supported by all input plugins.

 

broker_url

  • Value type is string
  • There is no default value for this setting.

Url to use when connecting to the JMS provider. This is only relevant for non-JNDI configurations.

destination

  • This is a required setting.
  • Value type is string
  • There is no default value for this setting.

Name of the destination queue or topic to use.

durable_subscriber

  • Value type is boolean
  • This is false by default
  • Requires pub_sub to be true

Setting this value to true will make subscriptions to topics "durable", which allowing messages that arrived on the specified topic while Logstash is not running to still be read. Without setting this value, any messages sent to a topic while Logstash is not actively listening will be lost. A durable subscriber specifies a unique identity consisting of the topic (destination), the client id (durable_subscriber_client_id) and subscriber name (durable_subscriber_subscriber_name). See your JMS Provider documentation for any further requirements/limitations around these settings.

  • Note that a durable subscription can only have one active subscriber at a time.
  • Note that this setting is only permitted when pub_sub is set to true, and will generate a configuration error otherwise

durable_subscriber_client_id

  • Value type is string
  • If durable_subscriber is set, the default value for this setting is Logstash, otherwise this setting has no effect

This represents the value of the client ID for a durable subscribtion, and is only used if durable_subscriber is set to true.

durable_subscriber_name

  • Value type is string
  • If durable_subscriber is set, the default value for this setting will be the same value as the destination setting, otherwise this setting has no effect.

This represents the value of the subscriber name for a durable subscribtion, and is only used if durable_subscriber is set to true. Please consult your JMS Provider documentation for constraints and requirements for this setting.

factory

  • Value type is string
  • There is no default value for this setting.

Full name (including package name) of Java connection factory used to create a connection with your JMS provider.

include_body

  • Value type is boolean
  • Default value is true

Include JMS Message Body in the event. Supports TextMessage, MapMessage and ByteMessage.

If the JMS Message is a TextMessage or ByteMessage, then the value will be in the "message" field of the event. If the JMS Message is a MapMessage, then all the key/value pairs will be added in the Hashmap of the event.

StreamMessage and ObjectMessage are not supported.

include_header

  • Value type is boolean
  • Default value is true

A JMS message has three parts:

  • Message Headers (required)
  • Message Properties (optional)
  • Message Bodies (optional)

You can tell the input plugin which parts should be included in the event produced by Logstash.

Include JMS Message Header Field values in the event.

include_properties

  • Value type is boolean
  • Default value is true

Include JMS Message Properties Field values in the event.

interval

  • Value type is number
  • Default value is 10

Polling interval in seconds. This is the time sleeping between asks to a consumed Queue. This parameter has non influence in the case of a subcribed Topic.

jndi_context

  • Value type is hash
  • There is no default value for this setting.

Only used if using JNDI lookup. Key value pairs to determine how to connect the JMS message brokers if JNDI is being used. Consult your JMS provider documentation for the correct values to use here.

jndi_name

  • Value type is string
  • There is no default value for this setting.

Only used if using JNDI lookup. Name of JNDI entry at which the Factory can be found.

keystore

  • Value type is path
  • There is no default value for this setting.

If you need to use a custom keystore (.jks) specify it here. This does not work with .pem keys

keystore_password

  • Value type is password
  • There is no default value for this setting.

Specify the keystore password here. Note, most .jks files created with keytool require a password

oracle_aq_buffered_messages

  • Value type is boolean
  • Default value is false

Receive Oracle AQ buffered messages. In this mode persistent Oracle AQ JMS messages will not be received. Only for use with Oracle AQ

password

  • Value type is string
  • There is no default value for this setting.

Password to use when connecting to the JMS provider.

pub_sub

  • Value type is boolean
  • Default value is false

If pub-sub (topic) style should be used. Note that if pub_sub is set to true, threads must be set to 1.

require_jars

  • Value type is array
  • There is no default value for this setting.

If you do not use an yaml configuration use either the factory or jndi_name. An optional array of Jar file names to load for the specified JMS provider. By using this option it is not necessary to put all the JMS Provider specific jar files into the java CLASSPATH prior to starting Logstash.

runner

  • DEPRECATED WARNING: This configuration item is deprecated and may not be available in future versions.

selector

  • Value type is string
  • There is no default value for this setting.

JMS message selector. Use in conjunctions with message headers or properties to filter messages to be processed. Only messages that match the query specified here will be processed. Check with your JMS provider for the correct JMS message selector syntax.

skip_headers

  • Value type is array
  • There is no default value for this setting.

If include_headers is set, a list of headers to skip processing on can be specified here.

skip_properties

  • Value type is array
  • There is no default value for this setting.

If include_properties is set, a list of properties to skip processing on can be specified here.

system_properties

Common Options

The following configuration options are supported by all input plugins:

Details

 

add_field

  • Value type is hash
  • Default value is {}

Add a field to an event

codec

  • Value type is codec
  • Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

enable_metric

  • Value type is boolean
  • Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

id

  • Value type is string
  • There is no default value for this setting.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 jms inputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

input {
  jms {
    id => "my_plugin_id"
  }
}

tags

  • Value type is array
  • There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

type

  • Value type is string
  • There is no default value for this setting.

Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
