Useful Kibana queries

All logs for GOV.UK on all environments are collected in Kibana, which you can access through Logit.

Kibana can be searched using the Lucene search syntax or full JSON-based Elasticsearch queries.


You can save and load queries using the buttons in the top right. You may want to use one of the existing queries as a starting point instead of writing a query from scratch.
