Status: Experimental
The Semantic Conventions for JSON-RPC extend and override the RPC spans and RPC metrics Semantic Conventions that describe common RPC operations attributes in addition to the Semantic Conventions described on this page.
rpc.system MUST be set to "jsonrpc".
| Attribute | Type | Description | Examples | Requirement Level |
|---|---|---|---|---|
rpc.jsonrpc.error_code |
int | error.code property of response if it is an error response. |
-32700; 100 |
Conditionally Required: If response is not successful. |
rpc.jsonrpc.error_message |
string | error.message property of response if it is an error response. |
Parse error; User already exists |
Recommended |
rpc.jsonrpc.request_id |
string | id property of request or response. Since protocol allows id to be int, string, null or missing (for notifications), value is expected to be cast to string for simplicity. Use empty string in case of null value. Omit entirely if this is a notification. |
10; request-7; `` |
Recommended |
rpc.jsonrpc.version |
string | Protocol version as in jsonrpc property of request/response. Since JSON-RPC 1.0 does not specify this, the value can be omitted. |
2.0; 1.0 |
Conditionally Required: If other than the default version (1.0) |
rpc.method |
string | The name of the (logical) method being called, must be equal to the $method part in the span name. [1] | exampleMethod |
