Fireship: Learn to instrument, collect, and visualize telemetry data using OpenTelemetry and the LGTM stack for better software observability.
Fireship - Grafana is the goat... Let's deploy the LGTM stack
The discussion focuses on using OpenTelemetry and the LGTM stack (Grafana, Prometheus, Tempo, Loki) to improve software observability by collecting and visualizing telemetry data. OpenTelemetry is a framework that gathers metrics, logs, and traces from software, working with any programming language. The LGTM stack provides the backend to store and visualize this data. Grafana serves as the UI for data visualization, Prometheus stores metrics, Tempo stores traces, and Loki stores logs. The video explains how to set up a telemetry framework using a Linux VPS from Hostinger, which offers a significant discount. The setup involves using Docker to deploy the LGTM stack, making it accessible via Grafana. The video also highlights the importance of connecting Grafana to data sources like Loki, Prometheus, and Tempo to populate them with data, using a Dino application as an example. This setup allows for real-time monitoring and analysis of software performance, helping to quickly identify and address issues.
Key Points:
- Use OpenTelemetry to collect metrics, logs, and traces from software.
- Deploy the LGTM stack (Grafana, Prometheus, Tempo, Loki) for data visualization and storage.
- Host the telemetry framework on a Linux VPS using Docker for easy setup.
- Connect Grafana to data sources to populate with real-time data for analysis.
- Monitor software performance and detect anomalies efficiently.

1. 🐞 The Fragility of Software and Bugs
- Experienced programmers often feel indifferent towards bugs because fixing one can lead to the creation of additional bugs, complicating the process. To improve software robustness, developers should implement comprehensive testing and debugging protocols.
- Critical bugs, such as those that caused the Apollo 13 oxygen tank explosion, cannot be ignored and require immediate attention to prevent catastrophic outcomes. Utilizing risk assessment tools and prioritizing high-impact bugs can mitigate such risks.
- Server downtime can result in significant financial losses, highlighting the importance of addressing production server issues promptly. Implementing automated monitoring and alert systems can reduce downtime and financial impacts.

3. 📚 Demystifying the Open Telemetry and LGTM Stack
- OpenTelemetry is a vendor-agnostic framework that collects telemetry data such as metrics, logs, and traces from software across any programming language.
- The LGTM stack involves Grafana for data visualization, Prometheus for storing metrics, Tempo for storing traces, and Loki for storing logs.
- Metrics, traces, and logs are collectively known as the 'Holy Trinity of software observability.'
- Grafana allows users to visualize data, set up alerts, and create dashboards.
- Prometheus is utilized as a time-series database specifically for metrics storage.
- Tempo is a database dedicated to storing traces, useful for tracking request flows and pinpointing bottlenecks.
- Loki serves as a database for log storage.
- The stack forms the 'otel lgtm' stack, integrating data collection via OpenTelemetry and visualization through Grafana.
- In practice, this stack allows for comprehensive monitoring and observability across systems, enabling quick identification and resolution of issues.
4. 🌐 Server Setup Made Easy with Hostinger
- Hostinger offers a Linux virtual private server plan, KVM 2, at $5.99 per month for 24 months, reflecting a 67% discount.
- The KVM 2 plan includes two CPUs and 8GB of RAM, providing significant computing power for hosting projects.
- Hostinger's biggest sale of the year is available until February 15th, offering substantial savings for early adopters.
- Fireship viewers can receive an additional 10% discount by using the code 'fireship'.
- The KVM 2 plan is ideal for developers looking for cost-effective and powerful server solutions, with features supporting high-performance applications and scalability.
5. 🚀 Deploying and Running the LGTM Backend with Docker
- Use the Docker image from Graphon to streamline deployment, eliminating the need for individual component installation.
- Set up a server with Docker pre-installed using Hostinger to simplify initial deployment steps.
- Establish SSH Key security for enhanced access control, though a root password can be used initially.
- Gain admin access by SSH into the server with root credentials and server IP address.
- Confirm Docker daemon operation using Docker commands; address potential issues with troubleshooting steps if needed.
- Initially, pull the Otel LGTM Docker image from the cloud, which takes about a minute.
- Access Grafana at Local Host via server IP on Port 3000 post-deployment for monitoring purposes.
- Note: Intended for educational and experimental use; not suitable for production environments.
- Include additional security practices for production scenarios and detailed SSH key setup instructions.
