Server stats
Memgraph supports multiple queries to get information about the instance that is being queried.
Instance version
To get the version of the instance being queried, run the following query:
SHOW VERSION;Storage information
Running the following query will return certain information about the storage of the current instance:
SHOW STORAGE INFO;The result will contain the following fields:
| Field | Description |
|---|---|
| vertex_count | The number of stored nodes (vertices). |
| edge_count | The number of stored relationships (edges). |
| average_degree | The average number of relationships of a single node. |
| memory_res | The non-swapped physical RAM memory a task has used, reported by the OS (in B, KiB, MiB, GiB or TiB). |
| disk_usage | The amount of disk space used by the data directory (in B, KiB, MiB, GiB or TiB). |
| memory_tracked | The amount of RAM allocated in the system and tracked by Memgraph (in B, KiB, MiB, GiB or TiB). For more info, check out memory control. |
| vm_max_map_count | The number of memory-mapped areas that the kernel allows a process to have. If it is unknown, returns -1. For more info, check out virtual memory section of the docs. |
| allocation_limit | The current allocation limit set for this instance (in B, KiB, MiB, GiB or TiB). For more info, check out the memory control. |
| global_isolation_level | The current global isolation level.For more info, check out isolation levels. |
| session_isolation_level | The current session isolation level. |
| next_session_isolation_level | The current next isolation level. |
| storage_mode | The current storage mode. For more info, check out storage modes. |
