We have just set up a sample Elastic/Logstash/Kibana server where logs are flying in from a Zuul server.
The only log data I'm interested in right now is these entries:
2017-12-12 12:50:55,456 DEBUG zuul.DependentPipelineManager: window size increased to 14
2017-12-12 12:50:57,097 DEBUG zuul.DependentPipelineManager: window size increased to 16
2017-12-12 12:52:12,069 DEBUG zuul.DependentPipelineManager: window size decreased to 8
2017-12-12 12:52:29,528 DEBUG zuul.DependentPipelineManager: window size decreased to 4
And I want to visualize these values. The problem(s) I have right now is that I do not know how I can extract the number from the log entry. And to be honest I don't know how to visualize it later either.
Anyone in this forum that have an idea how to do this? I'm thinking we have something like following steps:
- Somehow extract this value from every log row
- Put this data somewhere
- Visualize it.
EDIT: The log contains a lot of different data. This is not the only data. The only structure we know for sure about the log (if no stack trace gets in the way) is:
-timestamp- -service- -log message-.
And I want to extract values inside of the "log message".
