INFO

Returns server information and statistics.

Syntax

INFO [section ...]

Parameters

Parameter	Type	Required	Description
section	string	No	One or more section names to return. Case does not matter.

Return Value

Bulk string containing server information formatted as key:value pairs grouped under # Section headers. Sections are separated by an empty line.

Section	Fields
Server	server_name, kronotop_version, kronotop_git_sha1, kronotop_build_time, server_mode, os, arch_bits, java_version, process_id, run_id, tcp_port, server_time_usec, fdb_api_version, listener0, listener1
Cluster	cluster_enabled
Kronotop	cluster_name, member_id, member_status, bucket_shards, stash_shards, known_members, alive_members, primary_shards, standby_shards
Clients	connected_clients, clients_in_transaction, clients_in_multi, snapshot_read_clients, resp2_clients, resp3_clients
Memory	used_memory, used_memory_human, committed_memory, max_memory, max_memory_human, gc_count, gc_time_msec
Tasks	task_count, running_tasks
Volume	volume_count, volume0, volume1, …
Bucket	plan_cache_size, index_maintenance_workers, index_maintenance_processed_entries, index_maintenance_retried_conflicts, index_maintenance_last_run
Vector	vector_indexes, vector_bytes_used

Field notes:

• kronotop_version, kronotop_git_sha1 and kronotop_build_time are set at build time. A value that is not available is reported as unknown.
• run_id changes on every restart of the process. process_id is the operating system process id.
• tcp_port is the port the client listener is bound to. When the config sets port 0, this is the port picked at startup.
• listener0 is the client listener and listener1 the internal cluster listener. Each line has the bind host, the bound port and one advertise=host:port entry per advertised address. When no advertise address is configured, the entry is derived from the bind address.
• server_time_usec is the server clock in microseconds since the Unix epoch.
• member_status is one of RUNNING, UNAVAILABLE, STOPPED, UNKNOWN.
• known_members counts every member this node has seen. alive_members counts the ones with a recent heartbeat.
• primary_shards and standby_shards count the shards where this member is the primary or a standby.
• stash_shards is present only when stash.enabled is true.
• connected_clients counts every open connection on both listeners, client and internal.
• clients_in_transaction counts sessions between BEGIN and COMMIT or ROLLBACK. snapshot_read_clients counts sessions with SNAPSHOTREAD ON.
• clients_in_multi counts sessions between MULTI and EXEC or DISCARD. Present only when stash.enabled is true.
• resp2_clients and resp3_clients split connected_clients by the negotiated protocol version.
• used_memory is the JVM heap in use, committed_memory the heap reserved from the operating system and max_memory the heap limit. All three are in bytes. gc_count and gc_time_msec are totals since startup.
• task_count counts the background tasks registered on this member. running_tasks counts the ones executing at the moment of the call.
• volume_count counts the open volumes on this member. Each volumeN line has the volume name, its status (READWRITE, READONLY or INOPERABLE), vacuum_active (1 while a vacuum runs on that volume) and the operation counters appends, deletes, updates, gets, bytes_appended, bytes_read and segments_created. The counters start at zero on restart and VOLUME.STATS RESET clears them. Volumes are listed in name order.
• plan_cache_size is the number of cached query plans.
• index_maintenance_workers counts the index maintenance workers running on this member. The index_maintenance_processed_entries and index_maintenance_retried_conflicts totals cover those workers. index_maintenance_last_run is the most recent run time in milliseconds since the Unix epoch, or 0 when no worker is running.
• vector_indexes counts the vector graph indexes held in memory. vector_bytes_used is their total heap usage in bytes.

Behavior

Without arguments, every section is returned. With one or more section names, only the named sections are returned, in their normal order. Unknown names are ignored. If no name matches, the reply is an empty bulk string.

The names all, default and everything return every section.

The command reads only in-memory state. It does not touch FoundationDB and does not require the cluster to be initialized.

server_mode is always standalone and cluster_enabled is always 0. Kronotop does not use slot-based routing at the protocol level, so clients must connect in standalone mode.

Errors

No command-specific errors.
