Google Cloud have a nice Log Service, with some cool features (like Traces, I wrote before), but it lacks real analytics based on this logs. Like Kibana.
Fortunately Google Cloud can export logs to Cloud Storage. What’s cool is that this logs are in JSON format, so we could easily import them into ELK, without any complex Logstash configuration (honestly I cannot say that JSON schema fits well ELK, but still it’s easy to import).
I’ve prepared a basic Docker container with Elasticsearch, Logstash and Kibana configured for Appengine logs. Run ELK container with:
(you can get sources of this Docker image there).
