Semantic Conventions for Redis

Status: Experimental

The Semantic Conventions for Redis extend and override the Database Semantic Conventions that describe common database operations attributes in addition to the Semantic Conventions described on this page.

db.system MUST be set to "redis".

Attributes

Attribute	Type	Description	Examples	Requirement Level	Stability
db.redis.database_index	int	The index of the database being accessed as used in the SELECT command, provided as an integer. To be used instead of the generic db.name attribute.	0; 1; 15	Conditionally Required If other than the default database (0).
db.query.text	string	The full syntax of the Redis CLI command. [1]	HMSET myhash field1 'Hello' field2 'World'	Recommended [2]
network.peer.address	string	Peer address of the database node where the operation was performed. [3]	10.1.2.80; /tmp/my.sock	Recommended
network.peer.port	int	Peer port number of the network connection.	65123	Recommended if and only if network.peer.address is set.

[1]: For Redis, the value provided for db.query.text SHOULD correspond to the syntax of the Redis CLI. If, for example, the HMSET command is invoked, "HMSET myhash field1 'Hello' field2 'World'" would be a suitable value for db.query.text.

[2]: Should be collected by default only if there is sanitization that excludes sensitive information.

[3]: If a database operation involved multiple network calls (for example retries), the address of the last contacted node SHOULD be used.

Example

In this example, Redis is connected using a unix domain socket and therefore the connection string is left out. Furthermore, db.name is not specified as there is no database name in Redis and db.redis.database_index is set instead.
