Opendigitalradio has reserved a Private Entreprise Number for SNMP: 51436
OID: iso.org.dod.internet.private.enterprise.opendigitalradio (1.3.6.1.4.1.51436)
The goal of the Project SNMP is to make the monitoring statistics available through SNMP.
Steps
- Understand how to represent our monitoring values in a MIB
- Define a MIB structure and write a MIB
- Understand how to interface with snmpd and write scripts to connect the mmbTools with snmpd
Things to monitor
Things to monitor for the ODR-mmbTools:
- ODR-PadEnc
- Nothing
- ODR-AudioEnc
- Nothing. Audio levels are available through ODR-DabMux
- ODR-DabMux
- Seconds until expiry of TAI bulletin
- For each ZMQ input:
- state (0 Unknown, 1 NoData, 2 Unstable, 3 Silent, 4 Streaming)
- min buffer
- max buffer
- number of ZMQ underruns
- number of ZMQ overruns
- audio level peak, left channel
- audio level peak, right channel
- We could add the number of frames encoded, to detect a stuck multiplexer (To be discussed)
- ODR-DabMod
- one set of values for CFR
- Percentage of samples clipped
- Percentage of errors clipped
- MER after CFR
- PAPR before CFR
- PAPR after CFR
- The configured TIST offset
- The current TIST value
- To be added: The TIST value of the frame FCT=0
- one set of values for SDR device
- Number of underruns
- Number of late packets
- Number of frames transmitted
- one set of values for CFR
