Gelf input plugin
editGelf input plugin
edit- Plugin version: v3.3.0
- Released on: 2019-08-14
- Changelog
For other versions, see the Versioned plugin docs.
Installation
editFor plugins not bundled by default, it is easy to install by running bin/logstash-plugin install logstash-input-gelf
. See Working with plugins for more details.
Getting Help
editFor questions about the plugin, open a topic in the Discuss forums. For bugs or feature requests, open an issue in Github. For the list of Elastic supported plugins, please consult the Elastic Support Matrix.
Description
editThis input will read GELF messages as events over the network, making it a good choice if you already use Graylog2 today.
The main use case for this input is to leverage existing GELF logging libraries such as the GELF log4j appender.
Gelf Input Configuration Options
editThis plugin supports the following configuration options plus the Common Options described later.
Setting | Input type | Required |
---|---|---|
No |

Also see Common Options for a list of options supported by all input plugins.
use_udp
edit- Value type is boolean
-
Default value is
true
Whether to listen for gelf messages sent over udp
use_tcp
edit- Value type is boolean
-
Default value is
false
Whether to listen for gelf messages sent over tcp
port
edit- Value type is number
-
Default value is
12201
The port to listen on. Remember that ports less than 1024 (privileged ports) may require root to use. port_tcp and port_udp can be used to set a specific port for each protocol.
port_tcp
edit- Value type is number
- There is no default value for this setting.
Tcp port to listen on. Use port instead of this setting unless you need a different port for udp than tcp
port_udp
edit- Value type is number
- There is no default value for this setting.
Udp port to listen on. Use port instead of this setting unless you need a different port for udp than tcp
remap
edit- Value type is boolean
-
Default value is
true
Whether or not to remap the GELF message fields to Logstash event fields or leave them intact.
Remapping converts the following GELF fields to Logstash equivalents:
-
full\_message
becomesevent.get("message")
. -
if there is no
full\_message
,short\_message
becomesevent.get("message")
.
strip_leading_underscore
edit- Value type is boolean
-
Default value is
true
Whether or not to remove the leading \_
in GELF fields or leave them
in place. (Logstash < 1.2 did not remove them by default.). Note that
GELF version 1.1 format now requires all non-standard fields to be added
as an "additional" field, beginning with an underscore.
e.g. \_foo
becomes foo
Common Options
editThe following configuration options are supported by all input plugins:
Details
edit
codec
edit- 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
edit- 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
edit- 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 gelf inputs.
Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.
input { gelf { id => "my_plugin_id" } }
tags
edit- 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
edit- 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.
