This Add-on provides a dynamic lookup for parsing User Agent strings. This version was built to be faster, and does not require internet access from your Splunk systems.



This TA provides and external Python lookup that parses User Agents strings, such as those found in Web or Proxy logs.


To install:
1. Untar the tarball file in your $SPLUNK_HOME/etc/apps
2. Restart Splunk.


The lookup expects a field in the events (http_user_agent). Once that field exists (via extractions, alias or rename). Once that field exists, you can use it in a lookup command, as such:
index=web_proxy | lookup user_agents http_user_agent
The lookup will output the following fields:
* ua_os_family: The name of the client OS.
* ua_os_major: The major version of the client OS.
* ua_os_minor: The minor version of the client OS.
* ua_os_patch: The patch version of the client OS.
* ua_os_patch_minor: The minor patch version of the client OS.
* ua_family: The name of the UA ("Firefox", "IE")
* ua_major: The major version of the UA.
* ua_minor: The minor version of the UA.
* ua_patch: The patch version of the UA
* ua_device: The type of device used in the event.


To add your own user agents, you can use the YAML file in TA-user-agents/bin/ua_parser/ named regexes.yaml.


Support is on a best-effort basis. Need help? Use the Splunk community resources! I can be found on many of them:
