| ========================================================== | |
| This example demonstrates basics of Micrometer Jersey integration | |
| Contents | |
| -------- | |
| The mapping of the URI path space is presented in the following table: | |
| URI path | Resource class | HTTP methods | |
| ------------------------------------------ | ------------------------- | -------------- | |
| **_/micro/timed_** | MeasuredTimedResource | GET | |
| **_/micro/metrics_** | MetricsResource | GET | |
| **_/micro/summary_** | SummaryResource | GET | |
| Sample Response | |
| --------------- | |
| ```html | |
| --- (micro/timed) | |
| Requests to this method are measured. Use /init to see more | |
| ---- (micro/metrics) | |
| Static meters are initialized, try summary. If you want more measurements just refresh this page several times. | |
| ---- (micro/summary) | |
| Listing available meters | |
| Many occurrences of the same name means that there are more meters which could be used with different tags, but this is actually a challenge to handle all available metrics : | |
| http.timers; | |
| http.shared.metrics; | |
| Counts to the init page: 2, time spent on requests to the init page (millis): 2.759025 | |
| Requests to 'measure/timed' counts: 2, total time (millis): 40.110161 | |
| ``` | |
| Running the Example | |
| ------------------- | |
| Run the example using [Grizzly](https://javaee.github.io/grizzly/) container as follows: | |
| > mvn clean compile exec:java | |
| - <http://localhost:8080/micro/metrics> | |
| - after few request to the main page go to the url | |
| - <http://localhost:8080/micro/timed> | |
| - and see the responses from available resource pages | |
| - then go to the | |
| - <http://localhost:8080/micro/summary> | |
| - and see statistics for the micro/meter page |
