| ========================================================== |
| |
| 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 |
