+### SLM status
+Snapshot lifecycle management (SLM) status is "RUNNING" by default, but it can be stoped manually (for mantenaince purpouses, for instance). When this happens, no schedule snapshots will be taken. Docs: https://www.elastic.co/guide/en/elasticsearch/reference/master/snapshot-lifecycle-management-api.html 
+
+* To check the SLM status you can run `GET _slm/status`
+* To start SLM `POST /_slm/start` 
+* To stop SLM `POST /_slm/stop`
