Alert Manager for Prometheus (AWS EC2)

By -

Configure Alert Manager:

Step1: Download the latest Alert manager package.

wget https://github.com/prometheus/alertmanager/releases/download/v0.16.2/alertmanager-0.16.2.linux-amd64.tar.gz

unpack it: tar -xvzf alertmanager-0.16.2.linux-amd64.tar.gz

Move binary to /usr/local/bin/ folder 

sudo su

mv alertmanager-0.16.2.linux-amd64/alertmanager /usr/local/bin/

Step 2: Create an Alert manager user to run the Alert manager service.

sudo vi /etc/systemd/system/alertmanager.service

[Unit]

Description=AlertManager Server Service

Wants=network-online.target

After=network-online.target

[Service]

User=root

Group=root

Type=Simple

ExecStart=/usr/local/bin/alertmanager \

    --config.file /etc/alertmanager/alertmanager.yml

[Install]

WantedBy=multi-user.target

Step 3: Log in to the Prometheus server and open the prometheus.yml file.

vi /etc/prometheus/prometheus.yml

configure alertmanager and rules file .

# Alertmanager configuration

alerting:

  alertmanagers:

  - static_configs:

    - targets:

      - 'Serverip:9093'

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.

rule_files:

  - "alert_rules.yml"

Step 4: Create Rule file on that basic we will get notification 

sudo vi /etc/prometheus/alert_rules.yml

add below code into the file :

groups:

 - name: example

   rules:

   - alert: InstanceDown

     expr: up == 0

     for: 1m

Step 5: Create required directly and move  alertmanager.yml file

sudo mkdir /etc/alertmanager

sudo mv alertmanager-0.16.2.linux-amd64/alertmanager.yml /etc/alertmanager/

vi /etc/alertmanager/alertmanager.yml

edit the code as per below :

global:

 resolve_timeout: 1m

route:

  group_by: ['alertname']

  group_wait: 30s

  group_interval: 5m

  repeat_interval: 1h

  receiver: 'email_me'

receivers:

- name: 'email_me'

  email_configs:

  - to: kanchanawsdemo@gmail@gmail.com

    from: kanchanawsdemo@gmail.com

    smarthost: smtp.gmail.com:587

    auth_username: kanchanawsdemo@gmail.com

    auth_identity: kanchanawsdemo@gmail.com

    auth_password: asgbshrptryplekm

    send_resolved: true

inhibit_rules:

  - source_match:

      severity: 'critical'

    target_match:

      severity: 'warning'

    equal: ['alertname', 'dev', 'instance']

Step 6: Reload the daemon and start the alertmanager service 

sudo systemctl daemon-reload

sudo systemctl start alertmanager

sudo systemctl status alertmanager

sudo systemctl restart prometheus

sudo systemctl status prometheus

sudo systemctl start node_exporter

sudo systemctl stop node_exporter

sudo systemctl status node_exporter

What is DevOps? Hey Folks, We live in an era where machines and their Intelengency rule over Human Efforts and make our day-to-day tasks easy. Where we are now completely dependent upon machines for any small or big task. So all the backend processes used in the working of any Machines, Applications, or Websites need to be real quick and fast. For example, you prepared an application or a machine but it's the hardware or just a view. What makes it run is its software (Soul of any Machines, Application, or Website). Now, what is Software? Software is nothing but a collection of data or instructions that tell the Application (Computer, Machines, Hardware, Website, etc...) how to work. Software Life Cycle..! Okay so now you know what is software, but every software is first needed to be developed according to the requirement, and then it goes for testing if testing is failed it again goes for the redevelopment once the testing process is tested successfully then i

Microservices in GraphQL Hey Family, As you already know with the title we are going to discuss, Trending topics of 2020 today. I promise today's Blog would change your thinking about how Projects are currently working and how they will work in the coming time. Hold it and stay tuned for the below-mentioned topics: What is Microservices Architecture? GraphQL with Microservice using Docker Construct an application as a set of services that are, Highly maintainable and testable. Loosely coupled.  Deployed, Maintained and Developed independently From the starting separated by service boundaries which make it more convenient to scale up the development effort if needed Making it more convenient to choose the technology stack (programming databases, languages, etc.) which is best suited for the required service Monolithic vs Microservices Monolithic Monolithic Architecture Single Code Base Often time-consuming and confusing Difficult deployment with maintenance windo
