<hr />
<div>Opendigitalradio has reserved a Private Entreprise Number for SNMP: '''51436'''<br />
<br />
OID: <code>iso.org.dod.internet.private.enterprise.opendigitalradio</code> (1.3.6.1.4.1.51436)<br />
<br />
The '''goal of the Project SNMP''' is to make the monitoring statistics available through SNMP.<br />
<br />
==Steps==<br />
<br />
; Understand how to represent our monitoring values in a MIB<br />
: List what by whan to monitor and define keyword<br />
<br />
; Define a MIB structure and write a MIB<br />
: The best pratice seem to have 1 MIB by product/software and reserve one sub-level for each<br />
: 51436.1 for ODR-DabMux<br />
: 51436.2 for ODR-DabMod<br />
: 51436.3 for ODR-AudioEnc<br />
: 51436.4 for ODR-PasEnc<br />
<br />
; Understand how to interface with snmpd and write scripts to connect the mmbTools with snmpd<br />
<br />
==Things to monitor==<br />
<br />
Things to monitor for the ODR-mmbTools:<br />
<br />
* ODR-PadEnc<br />
** Nothing<br />
* ODR-AudioEnc<br />
** Nothing. Audio levels are available through ODR-DabMux<br />
* ODR-DabMux<br />
** Seconds until expiry of TAI bulletin<br />
** For each ZMQ input:<br />
*** state (0 Unknown, 1 NoData, 2 Unstable, 3 Silent, 4 Streaming)<br />
*** min buffer<br />
*** max buffer<br />
*** number of ZMQ underruns (overflows at 2^32 - 1)<br />
*** number of ZMQ overruns (overflows at 2^32 - 1)<br />
*** audio level peak, left channel<br />
*** audio level peak, right channel<br />
** We could add the number of frames encoded, to detect a stuck multiplexer (To be discussed)<br />
* ODR-DabMod<br />
** one set of values for CFR<br />
*** Percentage of samples clipped<br />
*** Percentage of errors clipped<br />
*** MER after CFR<br />
*** PAPR before CFR<br />
*** PAPR after CFR<br />
** The configured TIST offset<br />
** The current TIST value<br />
** To be added: The TIST value of the frame FCT=0<br />
** one set of values for SDR device<br />
*** Number of underruns<br />
*** Number of late packets<br />
*** Number of frames transmitted</div>Yoannhttps://wiki.opendigitalradio.org/index.php?title=User:Yoann&diff=1433User:Yoann2018-02-19T21:55:10Z<p>Yoann: Created page with "Yoann QUERET yoann@queret.net"</p>
