    To optimize DevTest admin we centralize the distributed logs (Registry, VSE, EDashboard)  with Filebeat / Logstash / Elasticsearch / Kibana suite.

    Do you have "grok" filters available to parse the log message structure?

    pbernard.1 Did you ever get the GROK commands to work against the DevTest log files? If so, can you share your findings?


    I just started looking at ElasticStack as a technique to parse the different types of output seen in the DevTest logs. I am curious if the following configuration gets the Elastic Stack output formatted close enough...  I would like the flow from filebeat -> logstash -> elastic stack and then use Kibana to render the dashboard.


    Enable filebeat to handle multiple lines when reading log files. The date/time stamp is an indicator of a new line.

    filebeat.yml file:


    - <path to log files>\vse.log

    - <path to logs>\vse_matches.log

    multiline.pattern: '^%(TIMESTAMP_ISO8601)'

    multiline.negate: true

    multiline.match: after


    Set up a grok to parse the date/time, define [Event Sink...] as "desc", INFO as "loglevel", com.itko... as "class", and remainder of the output until the new line as the "message".



    filter {

    grok {

    match => { "message" => "%{TIMESTAMP_ISO8601}( \()%{HOUR}:%{MINUTE}(\) |\)\[)%{GREEDYDATA:desc}(\] )%{LOGLEVEL}( )%{GREEDYDATA:class}( - )%{GREEDYDATA:message}" }


    Found this site to test grok commands: Test grok patterns 

    Found this site that shows some of the 'canned' grok patterns: logstash/grok-patterns at v1.4.2 · elastic/logstash · GitHub  

    Passed in some different combinations of log messages and the pattern worked.

    I have not tried multi-line output yet.
