SNMP Plugin for Graylog
This plugin provides an input plugin to receive SNMP traps.
Required Graylog version: 2.0.0 and later
This plugin is still pretty young and hasn't seen production traffic yet. Please let us know if you see any problems. Thank you!
Download the plugin
and place the
.jar file in your Graylog plugin directory. The plugin directory
plugins/ folder relative from your
graylog-server directory by default
and can be configured in your
graylog-server and you are done.
To get a basic set of MIB files on Linux you should install the
snmp-mibs-downloader packages (the names might be different depending on the OS) and execute the
download-mibs command. This fetches a lot of standard MIBs and installs them into the standard directories.
In the Graylog web interface, go to System/Inputs and create a new SNMP input like this:
Now you can point your SNMP devices to the configured IP address and port to receive SNMP traps.
The input creation dialog allows you to configure a path to custom MIB files. Alternatively you can also copy your custom MIB files into the
/usr/share/mibs directory which is included by default.
Please keep in mind that some MIBs need to be loaded with a special order. To achieve this create numbered sub-directories in your MIB load path and place the files there in the right order.
E.g. VMWare MIBs have to be loaded in this order:
So you should create a directory structure like:
Currently only the
public SNMP community is supported by the plugin.
This project is using Maven 3 and requires Java 8 or higher.
