Cara testing rabbitmq

setup docker

1.sudo nano /etc/docker/daemon.json (linux) atau ~/.docker/daemon.json kalo di macos
isi filenya:

{
   "metrics-addr": "0.0.0.0:9323",
   "experimental": true,
   "log-driver": "loki",
    "log-opts": {
        "loki-url": "http://localhost:3100/loki/api/v1/push",
        "loki-batch-size": "400"
    }

}
2. sudo systemctl restart docker
3. docker swarm init
4. firewall allow port 9323/tcp 
5. systemctl restart docker

1. docker pull lintangbirdas/go_log:v1 
2. docker pull lintangbirdas/monitor-service:v1
3. buat folder pb
4. buat .env isinya samain .env.example
5. generate protobuf code `make proto`

1.allow firewall port https://docs.docker.com/engine/swarm/swarm-tutorial/
2. docker stack ?

3.  buka grafana , tambah datasource prometheus (urlnya http://prometheus:9090).
4. buat service account & access tokennya, copy token ke .env monitor-service

insert data ke postgres

1. make migrate-up

2. insert data dummy ke masing masing table (lihat di migrations/.....up.sql)

jalanin docker swarm service

docker service create --name  go_container_log1  --publish 8231:8231 --replicas 2 --container-label  user_id=<user_id_di_table_container> --log-driver=loki \
    --log-opt loki-url="http://localhost:3100/loki/api/v1/push" \
    --log-opt loki-retries=5 \
    --log-opt loki-batch-size=400 \
    --log-opt loki-external-labels="job=docker,container_name=go_container_log1,userId=<user_id_di_table_container>" configs-go_container_log_user1:latest 


docker service create --name  go_container_log2  --publish 8232:8232 --replicas 2 --container-label  user_id=<user_id_di_table_container> --log-driver=loki \
    --log-opt loki-url="http://localhost:3100/loki/api/v1/push" \
    --log-opt loki-retries=5 \
    --log-opt loki-batch-size=400 \
    --log-opt loki-external-labels="job=docker,container_name=go_container_log2,userId=<user_id_di_table_container>" configs-go_container_log_user2:latest 



# harus localhost:3100/loki/api/v1/push biar bisa kedetect loki (pake loki:3100 gakbisa)

insert serviceID docker swarm ke setiap row

tambahin serviceID docker swarm ke setiap row di tabel container (harusnya container service yg namabahin)

buat dapetin serviceId: `docker service ls`
paling kiri id service ny.

rabbitmq

8. bikin queue & binding queuee

1. nama queue=monitor-billing, type: Quorum
2. queue binding utk monitor-billing:
exchangeName: monitor-billing
routingkey: monitor.billing.all_users
nama queue: monitor-billing

cron job dkron

9. buat cron di dkron

curl localhost:9911/v1/jobs -XPOST -d @scheduled_metrics_jobs.json

yang bawah ini gak usah dibaca & gak usah diikutin

query prome

1. buat dapetin metrics per swarm service:
sum(rate(container_cpu_usage_seconds_total{container_label_com_docker_swarm_service_id=~"swarmServiceId"}[1h])) * 100 * 7200 /3600
sum(avg_over_time(container_memory_usage_bytes{container_label_com_docker_swarm_service_id=~"swarmServiceId"}[1h])) * 30*24*3600 / 3600 / (1024^3)
sum(container_network_receive_bytes_total{container_label_com_docker_swarm_service_id=~"swarmServiceId"}) / 1024
sum(container_network_transmit_bytes_total{container_label_com_docker_swarm_service_id=~"swarmServiceId"}) / 1024

buat stop service docker swarm (semua replica container ): docker service scale go_container=0

Coba generate dashboard

-- get service account token

nama service account: adm
id serviceAcc: sa-adm
mending grafananya dipasangin volume biar gaperlu buat serviceAcc setiap setup grafana

harus masukin api key serviceAcc sa-adm ke config.yaml

genereate loki dashboard

curl localhost:3000/
