Implement Grafana with Prometheus in Docker

-

 

  1. Pull all the packages
    docker pull prom/prometheus:latest
    docker pull prom/node-exporter:latest
    docker pull grafana/grafana:latest
    docker pull influxdb:latest
  2. Configure Prometheus

    mkdir -p /etc/prometheus
    vi prometheus.yml # Paste below Lines in prometheus.yml
    # scrape configuration scraping a Node Exporter and the Prometheus # # # #server itself
    scrape_configs:
    # Scrape Prometheus itself every 5 seconds.
    - job_name: ‘prometheus’
    scrape_interval: 5s
    static_configs:
    - targets: [‘10.x.x.x:9090’]
  3. Run promrtheus
    docker run -d -p 9090:9090 --name prometheus -v /etc/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus:latest --config.file=/etc/prometheus/prometheus.yml
  4. Run Grafana
    docker run -d -p 3000:3000 --name grafana -e “GF_SECURITY_ADMIN_PASSWORD=admin_password” -v ~/grafana_db:/var/lib/grafana grafana/grafana:latest
  5. Run influxdb (optional): If want to store data
    docker run -d --name=influxdb --restart on-failure -p 8086:8086 -v influxdb_data:/var/lib/influxdb influxdb:latest -config /etc/influxdb/influxdb.conf
  6. Now let them provide the permission to access DB
    $docker exec -it influxdb bash
    $influx
    $CREATE DATABASE prometheus
    $use prometheus
    $CREATE RETENTION POLICY “30_days” ON “prometheus” DURATION 30d REPLICATION 1 DEFAULT
    $show RETENTION POLICIES
  7. To enable read/write in remote influxdb (add below configuration parameters)
    remote_write:
    - url: “http://10.x.x.x:8086/api/v1/prom/write?db=prometheus"
    remote_read:
    - url: “http://10.x.x.x:8086/api/v1/prom/read?db=prometheus"
  8. Run node-exporter on evrey node to monitor
    docker run -d -p 9100:9100 --name node-exporter -v “/proc:/host/proc” -v “/sys:/host/sys” -v “/:/rootfs” --net=”host” prom/node-exporter:latest --path.procfs /host/proc --path.sysfs /host/proc --collector.filesystem.ignored-mount-points “^/(sys|proc|dev|host|etc )($|/)”
  9. To Add nodes to prometheus (add below configuration parameters)
    vi prometheus.yml # Copy line of code given below
    # Scrape the Node Exporter every 5 seconds.
    - job_name: ‘node’
    scrape_interval: 5s
    static_configs:
    #Add target which u want to Monitor
    - targets: [‘10.x.x.x:9100’, ‘10.x.x.x:9100’, ‘10.x.x.x:9100’, ‘10.x.x.x:9100’, ‘10.x.x.x:9100’]
  10. For docker-compose and correct formatting please follow the below link
    https://gitlab.com/vineetkumar03/grafana
  11. To check Prometheus target : http://<IP>:9090
  12. Now to set up grafana:
    a. Login to grafana and go to “create a datasource ” link and then choose prometheus -> fill prometheus URL and port (other fill bydefault value)and save it.
    b. Go to + -> choose import and fill dashboard id or JSON file take it from below link
    c. Go to https://grafana.com/grafana/dashboards/ and choose any dashboard type , i choose two https://grafana.com/grafana/dashboards/405 (id will be 405)and https://grafana.com/grafana/dashboards/1860 (id will be 1860)after that save that dashboard

  Procedure to convert .iso image to .qcow2 images is as beow No any direct command avai lable to convert .iso to .qcow2 image so first convert it into raw image then raw image can be convert into qcow2 form. First Create a VDI image using VirtualBox:  Create VM (In Virtual Box) using .iso image with VDI Hard disk file type as shown in below Choose Hard disk Fie type 3.  Convert .vdi to raw format:  Now you can convert .vdi format to raw format using the  VBoxManage  command-line tool that ships with VirtualBox. In Linux, VirtualBox stores images by default in the  ~/VirtualBox VMs/  directory. The following example creates a raw image in the current directory from a VirtualBox VDI image $ VBoxManage clonehd ~/VirtualBox\ VMs/image.vdi image.img --format raw 4.  Convert Raw image to .qcow2 Format: $ qemu-img convert -f raw -O qcow2 image.img image.qcow2 5. Now you ca n  use .qcow2 image . If you have image in vmdk format then it ...
