+# Consul Info
+
+Command: `consul info`
+
+The info command provides various debugging information that can be
+useful to operators. Depending on if the agent is a client or server,
+information about different sub-systems will be returned.
+
+Here is an example output:
+
+    agent:
+        check_monitors = 0
+        check_ttls = 0
+        checks = 0
+        services = 0
+    consul:
+        bootstrap = true
+        leader = true
+        server = true
+    raft:
+        applied_index = 45758
+        commit_index = 45758
+        fsm_pending = 0
+        last_log_index = 45758
+        last_log_term = 3
+        last_snapshot_index = 45713
+        last_snapshot_term = 1
+        num_peers = 0
+        state = Leader
+        term = 3
+    serf-lan:
+        members = 1
+    serf-wan:
+        datacenters = 1
+        members = 1
+
+There are currently the top-level keys for:
+
+* agent: Provides information about the agent
+* consul: Information about the consul library (client or server)
+* raft: Provides info about the Raft [consensus library](/docs/internals/consensus.html)
+* serf-lan: Provides info about the LAN [gossip pool](/docs/internals/gossip.html)
+* serf-wan: Provides info about the WAN [gossip pool](/docs/internals/gossip.html)
+
+## Usage
+
+Usage: `consul info`
+
+The command-line flags are all optional. The list of available flags are:
+
+* `-rpc-addr` - Address to the RPC server of the agent you want to contact
+  to send this command. If this isn't specified, the command will contact
+  "127.0.0.1:8400" which is the default RPC address of a Consul agent.
