Stability Monitor Jaeger

Install Jaeger

To install Jaeger version 1.42.0 on a Linux system, follow the steps below. Jaeger is an open-source distributed tracing system, and you can install it using pre-built binaries, Docker, or through package managers. This guide will cover the installation process using pre-built binaries.

Step 1: Download the Jaeger Binary

Go to the Jaeger GitHub releases page and find version 1.42.0. Or use wget to directly download the binary:

wget https://github.com/jaegertracing/jaeger/releases/download/v1.42.0/jaeger-linux-amd64.tar.gz

Once downloaded, extract the .tar.gz file:

tar -xvzf jaeger-linux-amd64.tar.gz

This will create a folder containing the Jaeger binaries (jaeger-agent, jaeger-collector, jaeger-query, etc.).

Step 2: Move Jaeger to a System Directory

Move the extracted binaries to a directory in your PATH (e.g., /usr/local/bin):

mv jaeger-linux-amd64 /usr/local/bin/jaeger

Ensure the binaries are executable:

chmod +x /usr/local/bin/jaeger

Step 3: Create a Configuration File (Optional)

Create a directory for Jaeger configuration and add the jaeger-config.yaml file:

mkdir -p /etc/jaeger
vim /etc/jaeger/jaeger-config.yaml

The content for jaeger-config.yaml:

collector:
  http-port: 5775
  grpc-port: 14250

agent:
  http-port: 5778

query:
  http-port: 16686

storage:
  type: cassandra
  cassandra:
    contact-points:
      - "localhost:9042"
    keyspace: jaeger
    timeout: 30s

Step 4: Configure Data Directories

Define storage directories for Jaeger:

mkdir -p /var/jaeger/cassandra /var/jaeger/storage
chown -R jaeger:jaeger /var/jaeger

Create the Jaeger systemd service file:

vim /etc/systemd/system/jaeger.service

Add the following content:

[Unit]
Description=Jaeger
Documentation=https://www.jaegertracing.io/docs/latest/
After=network.target

[Service]
ExecStart=/usr/local/bin/jaeger --config.file=/etc/jaeger/jaeger-config.yaml
Restart=on-failure
User=delian
Group=delian

[Install]
WantedBy=multi-user.target

Step 5: Start Jaeger Service

Reload systemd, enable and start the Jaeger service:

systemctl daemon-reload
systemctl enable jaeger
systemctl start jaeger
systemctl status jaeger

To monitor logs:

journalctl -u jaeger -f

Verify the Jaeger version:

jaeger --version

Conclusion

By following the above steps, you should have Jaeger installed and running with the necessary configurations for distributed tracing. You can now proceed to integrate Jaeger with other components like Prometheus, Grafana, etc., for a complete monitoring and tracing solution.
