Elasticsearch¶
Managed instance of Elasticsearch. There’s a role for each supported major version, currently:
- elasticsearch5: 5.6.16
- elasticsearch6: 6.7.2
We also provide Kibana as a separate component.
Configuration¶
Upon activating the role, Elasticsearch forms a cluster with the same name as the VM.
To change the cluster name, add a file /etc/local/elasticsearch/clusterName,
with the cluster name as its sole contents.
To activate run sudo fc-manage --build (see Local configuration for details).
Elasticsearch instances are configured with a reasonable memory configuration, depending on the VMs configured memory.
To add additional configuration options, add a file /etc/local/elasticsearch/elasticsearch.yml.
Its contents will be appended to the base configuration.
Monitoring¶
The following checks are provided by the elasticsearch role:
- Circuit Breakers active
- Cluster Health
- File descriptors in use
- Heap too full
- Node status
- Shard allocation status
