There are times when you will want to get a summary of your graph to, for instance, see all the labels or get a count of nodes and relationships. The Cypher below will return that information.  As you'll see below, it returns the labels, relationship types and property keys. It also gives you a count of the nodes and relationships. 

CALL db.labels() YIELD label
RETURN {name:'labels', data:COLLECT(label)[..1000]} AS result
UNION ALL
CALL db.relationshipTypes() YIELD relationshipType
RETURN {name:'relationshipTypes', data:COLLECT(relationshipType)[..1000]} AS result
UNION ALL
CALL db.propertyKeys() YIELD propertyKey
RETURN {name:'propertyKeys', data:COLLECT(propertyKey)[..1000]} AS result
UNION ALL
CALL {
  MATCH () RETURN count(*) AS nodeCount
}
RETURN { name:'nodes', data: nodeCount } AS result
UNION ALL
CALL {
  MATCH ()-[]->() RETURN count(*) AS relCount
}
RETURN { name:'relationships', data: relCount } AS result

 

This will yield results like the following:

 

Use the following procedure to see your schema:

CALL db.schema.visualization()

You can view the property types for nodes in your graph by executing this query:

CALL db.schema.nodeTypeProperties()

You can view the property types for relationships in your graph by executing this query:

CALL db.schema.relTypeProperties()

To see all your indexes:

SHOW INDEXES

To get the 'Store Size', Node and Relationship 'Id Allocation' (allocated vs in use), and Transaction Metrics:

:SYSINFO
