Optimized chassis sensor support with JTI

You can use Junos telemetry interface (JTI) with remote procedure call (gRPC) services to export additional chassis sensors from an MX2010 or MX2020 router to an outside collector.

For network debugging, there are system-generated logs and SNMP traps available. However, some parameters, such as power entry module (PEM) voltage and PEM supply failure, have not been available in telemetry. We've now introduced these additional system parameters through chassis sensors that support messages logged as part of the SNMP traps for a field-replaceable unit (FRU), fan, PEM, or plane.

Use the resource path /components/component/properties/property in subscriptions for these additional chassis sensors:

• power-supply-failed
• chassisd-pem-breaker-trip
• chassisd-pem-voltage
• fan-blower-removed
• pem-not-powered
• chassisd-zone-blowers-speed-type
• chassisd-zone-blowers-speed
• temprature-back-to-normal
• over-temprature
• fru-failed
• plane-fru-check
• plane-online
