LogScreen

Loglines can be messy, read it better on a browser.

Usage

After installation, you can use LogScreen to view command outputs in a browser:

command | npx logscreen

Replace command with the actual command you want to execute. LogScreen will start a local server and open the logs in your default web browser.

Here are some examples:

Example 1: Viewing Docker Logs

  docker-compose up | npx logscreen

This example pipes the logs from a Docker Compose service into LogScreen, providing a more readable and interactive log view.

Example 2: Monitoring NPM Start Script

  npm start | npx logscreen

If you have a Node.js project with an `npm start` script, you can use LogScreen to monitor and navigate through the logs as your application runs.

Example 3: Tail Command Output

  tail -f /var/log/syslog | npx logscreen

For Linux users, you can use LogScreen with the `tail` command to follow and visualize real-time updates in system logs.

Monitoring Remote Server Logs

ssh user@remote-server 'tail -f /path/to/logs' | npx logscreen

SSH into a remote server and tail logs in real-time using logscreen for diagnosing issues on a production server.

Monitoring Nginx Access Logs

tail -f /var/log/nginx/access.log | npx logscreen

Tail Nginx access logs to observe incoming requests, response codes, and other relevant information.

Tail Apache Error Logs

tail -f /var/log/apache2/error.log | npx logscreen

Monitor Apache error logs to identify issues with your web server.

Google Cloud Functions Logging:

Use logscreen to monitor logs from Google Cloud Functions, gaining insights into function executions, errors, and overall performance.

gcloud functions logs read <function-name> | npx logscreen

Kubernetes Logs

kubectl logs -f <pod-name> | npx logscreen

AWS lambda

aws logs tail /aws/lambda/<function-name> | npx logscreen

EC2 Instance

ssh -i <private-key.pem> ec2-user@<instance-ip> 'tail -f /var/log/<your-log-file>' | npx logscreen

Monitoring Heroku Postgres Queries:

Tail logs related to database queries on a Heroku Postgres database for performance analysis and optimization.

heroku pg:psql --app <your-app-name> -c "tail -f /var/log/postgresql/postgresql.log" | npx logscreen

Replace the commands above with your specific use case to leverage the benefits of LogScreen's web-based log viewer.
