Can be extended with `page cache size` and `dbengine disk space`. <br />`save`: Netdata will save its round robin database on exit and load it on startup. <br />`map`: Cache files will be updated in real-time. Not ideal for systems with high load or slow disks (check `man mmap`). <br />`ram`: The round-robin database will be temporary and it will be lost when Netdata exits. <br />`none`: Disables the database at this host, and disables health monitoring entirely, as that requires a database of metrics. | | page cache size | 32 | Determines the amount of RAM in MiB that is dedicated to caching Netdata metric values. ||| -| dbengine disk space | 256 | Determines the amount of disk space in MiB that is dedicated to storing Netdata metric values and all related metadata describing them ||| +| dbengine disk space | 256 | Determines the amount of disk space in MiB that is dedicated to storing Netdata metric values and all related metadata describing them. ||| +| dbengine multihost disk space | 256 | Same functionality as `dbengine disk space`, but includes support for storing metrics streamed to a parent node by its children.
