💼 Key Projects & Contributions

Rack Monitoring System Development

  1. Monitoring Agent Design & Data Collection

    • #Golang, #IPMI, #SNMP, #ipmitool, #gosnmp, #pysnmp
    • Server Monitoring: Developed a Golang monitoring Agent to communicate directly with BMC via the IPMI (ipmitool) protocol, capturing server health status and sensor data in real-time.
    • Network & Power Monitoring: Conducted in-depth research on SNMP MIB (Management Information Base) files to implement data collectors for specific brands (Switch: Netgear, Cisco; PDU: Raritan). Utilized gosnmp and pysnmp packages to ensure cross-platform and cross-device compatibility.
    • Comprehensive Metrics:
      • Switch: Collected Network Traffic, Port On/Off Speed, Stacking Status, Max Speed, Health Status, Temperature, and Fan Speed.
      • PDU: Monitored environmental sensor data (Humidity, Temperature, Vibration, etc.) and Power Control (On/Off).

  2. Data Pipeline & Storage

    • #Prometheus, #TimeSeriesDB
    • Prometheus Integration: Formatted collected heterogeneous data into unified Prometheus Metrics, establishing a high-efficiency Time-series Pipeline to support high-frequency data ingestion and querying.

  3. Grafana Real-time Monitoring Dashboard

    • #Grafana, #Dashboard, #Visualization
    • War-Room Level Dashboard: Designed multi-dimensional Grafana Dashboards to display the real-time operational status of all equipment within the rack.
    • Anomaly Alerting: implemented threshold-based alerting. Visual indicators (color changes) and notifications allow the operations team to react immediately to critical events like overheating, fan failures, or network congestion.
