## 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]) 

```
