Filebeat is a lightweight, open source shipper for log file data. As the
next-generation Logstash Forwarder, Filebeat tails logs and quickly sends this
information to Logstash for further parsing and enrichment or to Elasticsearch
for centralized storage and analysis.
Filebeat can be added to any principal charm thanks to the wonders of being
a subordinate charm. The following example will deploy an ubuntu log source
along with the elk stack so we can visualize our log data.
juju deploy ~elasticsearch-charmers/bundle/elk-stack juju deploy xenial/filebeat juju deploy xenial/ubuntu juju add-relation filebeat:beats-host ubuntu juju add-relation filebeat logstash
Deploying the minimal Beats formation
If you do not need log buffering and alternate transforms on data that is
being shipped to ElasticSearch, you can simply deploy the 'beats-core' bundle
which stands up Elasticsearch, Kibana, and the known working Beats
juju deploy ~containers/bundle/beats-core juju deploy xenial/ubuntu juju add-relation filebeat:beats-host ubuntu juju add-relation topbeat:beats-host ubuntu
Changing what is shipped
By default, the Filebeat charm is setup to ship everything in:
If you'd rather target specific log files:
juju config filebeat logpath=/var/log/mylog.log
Testing the deployment
The applications provide extended status reporting to indicate when they are
This is particularly useful when combined with watch to track the on-going
progress of the deployment:
watch juju status
The message for each unit will provide information about that unit's state.
Once they all indicate that they are ready, you can navigate to the kibana
url and view the streamed log data from the Ubuntu host.
juju status kibana --format=yaml | grep public-address
Navigate to http://<kibana-ip>/ in a browser and begin creating your
Upgrades are handled at both the charm and apt repository levels. Use
upgrade-charm to get the latest charm code on all filebeat units:
juju upgrade-charm filebeat
Apt repositories are scanned any time the
install_sources config changes. If
a new version of filebeat is found in the configured repository,
will instruct operators to run the
reinstall action. This action must be
run on each filebeat unit:
juju run-action --wait filebeat/0 reinstall
reinstall action will stop the filebeat service, purge the apt package,
and reinstall the latest version available from the configured repository.
Scale Out Usage
As a subordinate charm, filebeat will scale when additional principal units are
added. For example, adding
ubuntu units that are related to
automatically install and configure
filebeat for the new unit(s).
juju add-unit ubuntu
To monitor additional applications, simply relate the filebeat subordinate:
