How Do I Configure the Threshold for CSS Slow Query Logs?¶
The slow query log settings of CSS are the same as those of Elasticsearch. You can configure slow query logs via the _settings API. For example, you can run the following command in Kibana to set the index level:
PUT /my_index/_settings
{
"index.search.slowlog.threshold.query.warn": "10s",
"index.search.slowlog.threshold.fetch.debug": "500ms",
"index.indexing.slowlog.threshold.index.info": "5s"
}
If a query takes longer than 10 seconds, a WARN log will be generated.
If retrieval takes longer than 500 milliseconds, a DEBUG log will be generated.
If an index takes longer than 5 seconds, an INFO log will be generated.
