If your service has a server::handlers::InspectRequests configured, then you may inspect the active requests. The feature is useful for investigating a broken production service to find request parameters that lead to handle malfunction.
Commands
server::handlers::InspectRequests provides the following REST API:
GET /service/inspect-requests
GET /service/inspect-requests?body=1
Note that the server::handlers::InspectRequests handler lives at the separate components.server.listener-monitor address, so you have to request them using the listener-monitor credentials. See Production configs and best practices for more info on configuration and ideas on how to change the /service/inspect-requests handle path.
Examples:
Get the requests in flight
In this example there is one in-flight request that is being executed for more than 3 seconds.
bash
$ curl http://localhost:8085/internal/inspect-requests | jq
[
{
"method": "GET",
"url": "/hello",
"http_version": "1.1",
"request_path": "/hello",
"handling-duration-ms": 3865,
"start-handling-timestamp": "Thu, 02 Dec 2021 07:57:22 UTC",
"host": "localhost",
"args": {},
"headers": {
"User-Agent": "curl/7.58.0",
"Accept": "*/*",
"Host": "localhost"
}
}
]
Get the bodies of the in-flight requests
In this example there are multiple in-flight request that actually have no body.
bash
$ curl http://localhost:8085/internal/inspect-requests?body=1 | jq
[
{
"request-body": "",
"method": "GET",
"url": "/hello",
"http_version": "1.1",
