How logging works on GOV.UK
For information on how to log in and view stacks, please see the GOV.UK Logit documentation.
Each machine runs Elastic Filebeat, and independently ships logs to the Logit-provided logstash endpoint.
Filebeat tails logs and can output to a variety of sources. It is fully incorporated into the Elastic ecosystem.
We use the
filebeat::prospector defined type to create the filebeat configuration on each instance.
Logstream and Logship
We have a defined type in our Puppet code which uses logship to tail logfiles.
We only use Logstream to send nginx metrics, via statsd, to Graphite.
In the future this will be replaced.
Kibana is the interface for viewing logs in Elasticsearch. Use the Logit interface to login to Kibana.
There’s some documentation on useful Kibana queries for 2nd line.
