lokitee

lokitee

lokitee streams lines of text from stdin, forwarding it to stdout and to Grafana Loki.

Credentials to Loki can be set via flag or environment variable:

• -addr or $LOKI_ADDR: Base URL of Loki to connect to (i.e., http://localhost:8080)
• -username or $LOKI_USERNAME: Basic auth username to use for requests. Optional.
• -password or $LOKI_PASSWORD: Basic auth password to use for requests. Optional.

By default, sent logs are written with the label set {job="lokitee"}. This can be changed with the -labels flag.

Installing

Use Go to install:

go install github.com/rfratto/lokitee@main

Examples

Write Hello, world to Loki:

echo "Hello, world!" | lokitee

Gotchas

lokitee currently splits lines from stdin and sends each line to Loki, preventing you from having one log entry that spans multiple lines.
