## How to find out the modules needed by jlink
Uncomment the `maven-dependency-plugin` plugin in `pom.xml`:
```xml
org.apache.maven.plugins
maven-dependency-plugin
${maven.dependency.plugin.version}
copy-dependencies
package
copy-dependencies
${project.build.directory}/libs
false
false
true
```
Then run the following commands in a terminal window:
```shell
mvn verify
jdeps --ignore-missing-deps -q -recursive --multi-release 21 \
--print-module-deps --class-path 'target/libs/*' target/spring-todo-app.jar
```
## How to start the setup
Place yourself in the root directory and run :
```shell
docker-compose up --build
```
You can access the following endpoints:
| Application | Local Endpoint |
|-------------|-----------------------|
| Todo App | http://localhost:8080 |
| Prometheus | http://localhost:9090 |
| Grafana | http://localhost:300 |
Now create some requests by running:
```shell
sh scripts/load.sh
```
### How to detect missing JVM NativeMemoryTracking flag
Please take a look at /scripts/flag.sh and:
```shell
sh scripts/flag.sh
```
### How to track Native Memory Used
Run
```shell
sh scripts/track.sh
```
### How to query stats
Run
```shell
sh scripts/query.sh
```
## Prometheus
### Look at CPU Load Machine Total vs HTTP server requests
```shell
rate(jdk_CPULoadmachineTotal[1m])
or rate(http_server_requests_seconds_sum{method="POST", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="GET", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="PUT", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="DELETE"}[1m])
```
### Look at Garbage Collection Longest Pause vs HTTP server requests
```shell
rate(jdk_GarbageCollectionlongestPause[1m])
or rate(http_server_requests_seconds_sum{method="POST", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="GET", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="PUT", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="DELETE"}[1m])
```
### Look at Garbage Collection Sum of Pauses vs HTTP server requests
```shell
rate(jdk_GarbageCollectionsumOfPauses[1m])
or rate(http_server_requests_seconds_sum{method="POST", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="GET", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="PUT", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="DELETE"}[1m])
```
### Look at GCHeapSummary Heap Used
```shell
rate(jdk_GCHeapSummaryheapUsed[1m])
or rate(http_server_requests_seconds_sum{method="POST", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="GET", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="PUT", uri="/api/todo"}[1m])
or rate(http_server_requests_seconds_sum{method="DELETE"}[1m])
```
