Howto integrate to prometheus/grafana

1. Download prometheus

mkdir prometheus
sudo mv prometheus /opt/
cd /opt/prometheus

curl -L https://github.com/prometheus/prometheus/releases/download/v2.3.2/prometheus-2.3.2.linux-amd64.tar.gz | tar xvzp --strip-components=1
curl -L https://github.com/phuslu/remote_node_exporter/releases/download/v0.12.0/remote_node_exporter-0.12.0.linux-amd64.tar.gz | tar xvzp --strip-components=1

2. Configure prometheus.yml

global:
  scrape_interval:     15s
  evaluation_interval: 15s

scrape_configs:
  - job_name: 'remote_node_exporter'
    scheme: 'http'
    static_configs:
      - targets: ['192.168.2.2:10001']
        labels:
          instance: lab.phus.lu

3. Create systemd services

cat <<EOF >prometheus.service
[Unit]
Description=prometheus

[Service]
WorkingDirectory=/opt/prometheus
ExecStart=/opt/prometheus/prometheus --config.file=/opt/prometheus/prometheus.yml
ExecReload=/bin/kill -HUP \$MAINPID
Restart=always
LimitNOFILE=100000
LimitNPROC=100000

[Install]
WantedBy=multi-user.target
EOF

cat <<EOF >remote-node-exporter.service
[Unit]
Description=prometheus remote node exporter

[Service]
ExecStart=/opt/prometheus/remote_node_exporter --config.file=/opt/prometheus/remote_node_exporter.yml
Restart=always
LimitNOFILE=100000
LimitNPROC=100000

[Install]
WantedBy=multi-user.target
EOF

4. start monitoring services

sudo systemctl enable $(pwd)/*.service
sudo systemctl start remote-node-exporter
sudo systemctl start prometheus

5. Install grafana

mkdir grafana
sudo mv grafana /opt/
cd /opt/grafana

curl -L https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.2.2.linux-x64.tar.gz | tar xvzp --strip-components=1

cat <<EOF >grafana.service
[Unit]
Description=grafana

[Service]
WorkingDirectory=/opt/grafana
ExecStart=/opt/grafana/bin/grafana-server
ExecReload=/bin/kill -HUP \$MAINPID
Restart=always
LimitNOFILE=100000
LimitNPROC=100000

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl enable $(pwd)/grafana.service
sudo systemctl start grafana.service

6. Impport to grafana dashboard

• Visit http://<your_ip>:9090 to verify prometheus api
• Import http://<your_ip>:9090 as datasource to grafana server
• Import grafana_dashboard.json as dashboard to grafana server

Error index out of range

Hi There,
Thanks for your exporter, it's very useful for me.
But I met an error as below:

ARM release

Hello phuslu!

Is it possible to compile this for ARM devices?
I would like to target some *Pi-s with it.

Broken dependencies while building Dockerfile

Hi,

building your image yields error:

Step 5/11 : RUN go get -d -v github.com/prometheus/common/log
 ---> Running in 79f55f7ea349
go: downloading github.com/prometheus/common v0.32.1
go get: module github.com/prometheus/common@upgrade found (v0.32.1), but does not contain package github.com/prometheus/common/log
The command '/bin/sh -c go get -d -v github.com/prometheus/common/log' returned a non-zero code: 1

Do you plan on updating dependencies?

will you add support for mdadm status from /proc/mdstat?

can we change scrape interval

I am running remote node exporter and node exporter simultaneously but output making difference
In Prometheus is use scrape interval 15s .

Release is not compressed

It seems the file remote_node_exporter-0.12.0.linux-amd64.tar.gz is not compressed with gzip.

You must be missing the z in tar czf ...
