Disk usage | Elasticsearch Documentation

The disk usage metric shows the percentage of space used on the data partition of a node. This includes the main files containing your data such as index and documents.

We recommend that disk usage is kept to less than 70% during normal running to allow temporary working space. If your cluster is regularly exceeding 70% then you should consider adding capacity or removing data.

Instaclustr Support monitors disk use for all managed clusters and will notify you if your cluster is exceeding recommended levels of disk usage.

We strongly recommend maintaining a minimum of 30% free disk space in normal operations. This is to ensure there is sufficient available space for Elasticsearch to perform operations.

If your cluster is simply filling up with data then it can be easily scaled out by adding additional nodes. To do this, use the add node feature on our console or contact support@instaclustr.com for assistance.
