Setup monitoring via our blog: How to set up Elastic Cloud Advice from Elastic Support
-
Enable Slow Logs. E.g. using
kibana_sample_data*PUT kibana_sample_data*/_settings { "index.search.slowlog.threshold.query.warn": "0s" } -
(Wait for natural event to occur or) induce Slow Log
-
Create Index Pattern against
kibana_sample_data* -
In Discover, load all Index Pattern data (bets are will take longer than 1s & generate a SlowLog). After we'll find SlowLog outputs from
elastic-cloud-7*E.g. NOT this output (which was us updating the settings)

We can use these fields to generate a query filter to view only these logs:
{ "query": { "bool": { "must": { "query_string": { "analyze_wildcard": true, "query": "event.dataset:elasticsearch.slowlog AND log.level:WARN" }}}}} -
Now, we'll go to create a Kibana Alert of type Elasticsearch query with our query. More info: general rule details. I'll just do an index write, but many customers point their Actions to their Email Connectors.

Once created, related Kibana Alert JSON on backend will be
``` GET .kibana/_search?filter_path=hits.hits {"query":{"term":{"alert.name.keyword":{"value":"test_00796515" }}}} { "hits" : {"hits" : [{ "_index" : ".kibana_7.14.0_001", "_type" : "_doc", "_score" : 1.8382792, "_id" : "alert:5cef3390-0b42-11ec-b5ac-13d3190df5d9", "_source" : { "alert" : { "params" : { "esQuery" : """{ "query": { "bool": { "must": { "query_string": { "analyze_wildcard": true, "query": "event.dataset:elasticsearch.slowlog AND log.level:WARN" }}}}}""", "size" : 100, "timeWindowSize" : 5, "timeWindowUnit" : "m", "threshold" : [1 ], "thresholdComparator" : ">", "index" : ["elastic-cloud-logs-*"], "timeField" : "@timestamp" }, "consumer" : "alerts", "schedule" : {"interval" : "5m"}, "tags" : [ ], "name" : "test_00796515", "throttle" : null, "actions" : [{"group" : "query matched", "params" : {"documents" : [{"test" : "success, yay!"} ] }, "actionRef" : "action_0", "actionTypeId" : ".index"} ], "enabled" : true, "alertTypeId" : ".es-query", "notifyWhen" : "onActiveAlert", "apiKeyOwner" : "199699336", "apiKey" : "REDACTED", "createdBy" : "199699336", "updatedBy" : "199699336", "createdAt" : "2021-09-01T16:33:40.474Z", "updatedAt" : "2021-09-01T16:33:40.474Z", "muteAll" : false, "mutedInstanceIds" : [ ], "executionStatus" : { "status" : "active", "lastExecutionDate" : "2021-09-01T16:33:45.425Z", "error" : null }, "meta" : {"versionApiKeyLastmodified" : "7.14.0"}, "scheduledTaskId" : "5e0389c0-0b42-11ec-b5ac-13d3190df5d9"}, "type" : "alert", "references" : [{"id" : "3d72e610-0b42-11ec-b5ac-13d3190df5d9", "name" : "action_0", "type" : "action"} ], "migrationVersion" : {"alert" : "7.13.0"}, "coreMigrationVersion" : "7.14.0", "updated_at" : "2021-09-01T16:33:46.565Z" } } ] } } ```

Since our alert's marked
executionStatus.status:active, we can check to see our test fired. Once confirmed we're good to go.
