  • Elasticsearch has been switched to read-only mode due to low disk space (<1 GB). Please free up some space.

  • Elasticsearch is a distributed search engine which helps to analyze huge volumes of data in near real-time. Unlike conventional techniques, Elasticsearch fetches data real quick which results in reduced report generation time, quicker threat detection, and a lot more. In M365 Manager Plus we use Elasticsearch in the following modules,

    • Reports
    • Audit
    • Alert
    • Content search

    Recommended:

    It is advised to have at least 1 GB free hard disk space for Elasticsearch to function effectively. If the disk space runs low, Elasticsearch will be switched to read-only mode, during which the data collected from native will not be stored in the engine. To enable Write for Elasticsearch,

    1. Free up space in hard disk to maintain the recommended threshold.
    2. Restart the product.
