This document introduces the performance testing metrics that PTS supports outputting to Prometheus for users' reference during integration.

Tag

Default Tag

All performance testing metrics output by PTS include the following three tags:
Instance: The IP address of the stress machine.
Job: PTS stress testing task ID, such as job-xxx.
Region: The region where the stress testing task runs, such as ap-guangzhou.

Other Tags

Other tags included in some performance testing metrics:
Method: The name of the request method. For example, in the HTTP protocol, the method can be GET, POST, PUT, etc.
Proto: Protocol name. For example, in the HTTP protocol, proto can be HTTP/1.1, HTTP/2, etc.
Service: Service name. For example, in the HTTP protocol, the service is the request URL, such as http://httpbin.org/get, etc.
Status: Response status code. For example, in the HTTP protocol, the status codes include 200, 404, 500, etc.
Result: Response details. The request result or failure can be judged through result.
The request is normal, and the value of the result Tag is ok.
Request failure, the result Tag carries an error code and description.
Detailed error code manual: Error Code Manual.
check: Check name, with the Tag value being the checkpoint name set by the user.
Note:
In WebSocket, the event corresponds to the method Tag, including:
Uplink messages: sendPing, sendPong, sendMessage, sendBinaryMessage.
Downstream messages: ping, pong, message, binaryMessage, error, open, close.
