 ### Configuration
 
-**NOTE:** The exporter fetches information from an ElasticSearch cluster on every scrape, therefore having a too short scrape interval can impose load on ES master nodes, particularly if you run with `--es.all` and `--es.indices`. We suggest you measure how long fetching `/_nodes/stats` and `/_all/_stats` takes for your ES cluster to determine whether your scraping interval is too short. As a last resort, you can scrape this exporter using a dedicated job with its own scraping interval.
