Episode notes
INSIGHT

Building Observability Without SNMP

  • It is possible to build network observability without SNMP using GNMI and modern tools.
  • The process is similar, involving subscription to data paths and capturing them in databases.
ADVICE

Leverage Existing SNMP Tools

  • Use existing SNMP tooling like LibreNMS for reliable, proven network monitoring while modern solutions mature.
  • A comprehensive open source telemetry platform for GNMI is still needed, especially outside service providers.
INSIGHT

Power of On-Change Telemetry

  • GNMI's on-change telemetry provides unique event-driven data not possible with SNMP polling.
  • On-change subscription minimizes storage by sending data only when changes occur, enhancing efficiency.
