Get Started with LogFlux in 5 Minutes

1. Get an API Key

Sign in to dashboard.logflux.io and go to Settings > API Keys. Create a new key – it will look like eu-lf_abc123....

2. Install the Agent

Quick install (Linux/macOS):

1

curl -fsSL https://download.logflux.io/agent/install.sh | sudo bash

Other methods:

See Agent Installation for all options including RPM and Kubernetes.

3. Configure

Set your API key in the agent config:

1

sudo nano /etc/logflux-agent/agent.yaml

1

api_key: eu-lf_your_api_key_here

That’s the only required field. Start the agent:

1

sudo systemctl enable --now logflux-agent

4. Send Your First Log

1

logflux -message "Hello from LogFlux!"

With severity levels:

1
2
3

logflux -message "Application started" -level info
logflux -message "Connection slow" -level warn
logflux -message "Request failed" -level error

5. Verify

1
2

logflux -health     # Check agent status
logflux -version    # Check version

Your logs are now encrypted client-side (AES-256-GCM) and flowing to LogFlux. Encryption keys are negotiated automatically during the handshake – no manual key setup required. See Security & Encryption for the full protocol.

Use an SDK Instead

Send logs directly from your application code – no agent needed:

All SDKs handle encryption and key negotiation automatically. Initialize with your API key and start logging:

// Go example
logflux.Init(logflux.Options{
    APIKey: "eu-lf_your_api_key_here",
    Node:   "my-service",
})
defer logflux.Close()

logflux.Info("Application started")
logflux.Error("Something broke", logflux.WithStack())
