You Should Know:
1. OpenTelemetry (OTel) Setup & Basic Commands
OpenTelemetry is a collection of tools for capturing and exporting telemetry data (metrics, logs, traces).
Installation (Linux):
<h1>Install OpenTelemetry Collector</h1> curl -L https://github.com/open-telemetry/opentelemetry-collector-releases/releases/download/v0.60.0/otelcol_0.60.0_linux_amd64.tar.gz | tar xz sudo mv otelcol /usr/local/bin/
Basic Configuration (`otel-config.yaml`):
receivers: otlp: protocols: grpc: http: exporters: logging: logLevel: debug service: pipelines: traces: receivers: [otlp] exporters: [logging]
Run the Collector:
otelcol --config=otel-config.yaml
2. Prometheus Monitoring Setup
Prometheus is a powerful metrics-based monitoring tool.
Installation:
wget https://github.com/prometheus/prometheus/releases/download/v2.47.0/prometheus-2.47.0.linux-amd64.tar.gz tar xvf prometheus-<em>.tar.gz cd prometheus-</em>/
Configure `prometheus.yml`:
global: scrape_interval: 15s scrape_configs: - job_name: 'node_exporter' static_configs: - targets: ['localhost:9100']
Start Prometheus:
./prometheus --config.file=prometheus.yml
3. Key Linux Commands for Observability
<h1>Check system metrics</h1> top htop vmstat 1 <h1>Network monitoring</h1> iftop nload netstat -tuln <h1>Log inspection</h1> journalctl -f tail -f /var/log/syslog
4. Windows Observability Commands
<h1>Check event logs</h1> Get-EventLog -LogName System -Newest 20 <h1>Monitor processes</h1> Get-Process | Sort-Object CPU -Descending <h1>Network stats</h1> Get-NetTCPConnection -State Established
What Undercode Say:
Observability is critical for modern IT infrastructure. Tools like OpenTelemetry and Prometheus provide deep insights into system performance. Always verify configurations, use secure protocols (HTTPS/gRPC), and automate alerts for anomalies. Combine logs, metrics, and traces for full-stack visibility.
Expected Output:
- OpenTelemetry Collector logs
- Prometheus metrics dashboard
- Real-time system monitoring via CLI
