title: Node exporter and prometheus

---



# Monitoring

apt-install seh bhi kr skte h .  But all the modules that are download cannot be stopped like we can do them manually as in step 2 of prometheus.

## Node exporter
- Make sure port 9100 is not in use. 
`netstat -tulnp | grep 9100`
- Download node exporter to /tmp: 
`wget https://github.com/prometheus/node_exporter/releases/download/v1.5.0/node_exporter-1.5.0.linux-arm64.tar.gz -P /tmp`
- Make a directory: 
`mkdir -p /var/lib/prometheus`
- Extract binary:
 `tar xf /tmp/node_exporter-1.5.0.linux-arm64.tar.gz -C /var/lib/prometheus/ --strip-components=1`
- Create symlink to /usr/bin: 
`cp -s /var/lib/prometheus/node_exporter /usr/bin/`
- Create systemd service: 
`nano /usr/lib/systemd/system/prometheus-node-exporter.service`
- Paste these contents in the above file:
```
[Unit]
Description=Prometheus Node Exporter
Wants=network-online.target
After=network-online.target

[Service]
ExecStart=/usr/bin/node_exporter --no-collector.nfs --no-collector.mdadm --no-collector.arp --no-collector.bcache --no-collector.btrfs --no-collector.entropy --no-collector.infiniband --no-collector.nfsd --no-collector.nvme --no-collector.powersupplyclass --no-collector.rapl --no-collector.softnet --no-collector.tapestats --no-collector.thermal_zone
Restart=always
RestartSec=30s
KillMode=process

[Install]
WantedBy=multi-user.target

```
- enable the service: 
`systemctl enable --now prometheus-node-exporter.service`

- check if its running
`systemctl status prometheus-node-exporter.service`

- **Runs on port 9100**

# Prometheus

1. Make a directory
2. nano docker-compose.yml

```
#paste these contents in the compose file

version: '3.9'

services:
  prometheus:
    image: prom/prometheus:v2.40.2
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'
      - '--web.console.libraries=/usr/share/prometheus/console_libraries'
      - '--web.console.templates=/usr/share/prometheus/consoles'
      - '--storage.tsdb.retention.time=30d'
      - '--storage.tsdb.retention.size=150GB'
      - '--log.level=warn'
      - '--log.format=logfmt'
    network_mode: "host"
    expose:
      - 9090

```

3. nano prometheus.yml

```
global:
  scrape_interval:     15s
  evaluation_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']

  - job_name: 'node_exporter'
    static_configs:
      - targets: ['localhost:9100']
```

- **Runs on port 9090**

# Prometheus with alertmanager

1. Since we know that prometheus is used to store and analyze the metrics sent by the node manager . Now we'll integrate alertmanager which will handle the alert from the Prometheus and send the alerts to the respective source like email , slack  , telegram.
2. Make **rules.yml** to define the rules , for starting lets make a rule like for eg if the node exporter goes down the alert should come .
```
groups:
  - name: example
    rules:
      - alert: NodeExporterDown
        expr: up{job="node_exporter"} == 0
        for: 1m
        labels:
          severity: critical
        annotations:
          summary: "Node Exporter is down"
          description: "The Node Exporter job is reporting no uptime, indicating that the exporter is down."
```

3. Now add rules file in **prometheus.yml**

```
global:
  scrape_interval:     15s
  evaluation_interval: 15s

  external_labels:
      monitor: 'example'

alerting:
  alertmanagers:
    - static_configs:
        - targets: ['localhost:9093']


rule_files:
  - "/etc/prometheus/rules/rules.yml"

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['localhost:9090']

  - job_name: 'node_exporter'
    static_configs:
      - targets: ['localhost:9100']
```
```
1. The alerting section is where you configure how Prometheus handles alerts.
Within this section, you define the alertmanagers, which are responsible 
for receiving and managing alerts.

2. /etc/prometheus/rules/rules.yml specifies 
the path to the rule file that Prometheus should load.
```

4. Configuring the **alertmanager.yml**

```
route:
  group_wait: 10s
  group_interval: 30s
  repeat_interval: 30m
  receiver: "email-receiver"

receivers:
- name: "email-receiver"
  email_configs:
  - to: "varindakhanna2002@gmail.com"
    from: "alertmanager@example.com"
    smarthost: "smtp.gmail.com:587"
    auth_username: "yourgmail@gmail.com"
    auth_password: "mygmailidpassword"
    auth_identity: "alertmanager@example.com"
    require_tls: true
```

5. Configuring the **docker-compose.yml**

```
version: '3.9'

services:
  prometheus:
    image: prom/prometheus:v2.40.2
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml

      - '--web.console.libraries=/usr/share/prometheus/console_libraries'
      - '--web.console.templates=/usr/share/prometheus/consoles'
      - '--storage.tsdb.retention.time=30d'
      - '--storage.tsdb.retention.size=150GB'
      - '--log.level=warn'
      - '--log.format=logfmt'
    network_mode: "host"
    expose:
      - 9090
    restart: unless-stopped

  alertmanager:
    image: prom/alertmanager:v0.24.0
    volumes:
      - ./alertmanager.yml:/etc/alertmanager/alertmanager.yml
      - ./data:/alertmanager
    command:
      - '--config.file=/etc/alertmanager/alertmanager.yml'
      - '--storage.path=/alertmanager'
    network_mode: "host"
    expose:
      - 9093
    restart: unless-stopped
```

# Nginx and Reverse proxy

Nginx is a **web server** that is going to serve content to our browser. 

Nginx:

Nginx is like a traffic cop for the internet. It's a software that runs on servers, helping to manage the flow of information between users (like you on your computer or phone) and websites. When you type a web address into your browser, Nginx helps make sure your request gets to the right place on the internet and brings back the web page you want to see. It's known for being fast and efficient, so it can handle lots of requests at once without slowing down.

Reverse Proxy:

A reverse proxy is like a middleman between you and the websites you visit. Imagine you want to visit a website, but instead of connecting directly to the website's server, you connect to a reverse proxy server first. This reverse proxy then forwards your request to the website's server on your behalf, receives the response from the website's server, and sends it back to you.
Reverse proxies are often used for security, load balancing, and caching. 

In summary, Nginx is like a traffic cop that helps manage internet traffic, and a reverse proxy is a middleman that forwards your web requests to the right place on the internet and brings back the web pages you want to see. Together, they help make the internet faster, more secure, and more reliable for everyone.

## Inside of nginx.conf


1. We generally see a key value pattern . They are known as directives and 
2. Blocks of code are called context for eg http context etc.
3. Within context we have directives.
4. **Nginx Location** - This helps us to define certain end points that we can hit and server different types of html . For eg default is ```http://server_ip/80``` , we want to the end point ```http://server_ip/80/fruits``` 

### Steps (nginx -s reload)

1. Made a directory
2. index.html
3. Then served it on the nginx port.
 ```
 http {
    server {
        listen 82;
        root /nginxprac;
    }
}

events {}
 ```
 
4. To add css we can use types as well but it is a long approach
```
types{
   text/css   css
   text/html  html
}
```

5. Instead of this , we use mime types
```
 include mine.types;
```
6. Using nginx location context
```
http {
    include mime.types;
    server {
        listen 82;
        root /nginxprac;

        location /fruits {
            root /nginxprac;
        }

    }
}

# location context , will automatically join the link /nginxprac/fruits .
Meaning the directory name should be same as the end point.
```

7. Now if I want to redirect to fruits only even if going to /carbs

```
 location /carbs {
            alias /nginxprac/fruits;
        }

```

8. If we have another file instead of index.html . Use try_files

```
location /carbs{
           try_files /carbs/carbs.html /index.html =404
           }
```

9. If you want to redirect

```
location /crops {
            return 307 /fruits;
        }
    
url hit = http://129.154.245.45:82/fruits/
```

### Nginx as a Load Balancer

1. It uses round - robin spproach to allocate ther server.
2. Redirect to some other server
```
http {
   upstream backendserver{

      server 150.230.238.61:8001;
 }
   server {
       listen 82;
       root /nginxprac;

       location / {
           proxy_pass http://backendserver/;
}
   }
}

events {}
```
