Zabbix SNMPv2 Livewire monitoring

Monitoring of Telos Alliance Livewire devices via SNMPv2, such as the Axia xNodes.

There are low-level discovery rules for detecting and monitoring the available Livewire source and destination ports.

This template is part of RaBe's Zabbix template and helpers collection.

Usage

1. Download the MIB files for Axia xNodes
2. Place the MIB files into your default MIB directory (usually /usr/local/share/snmp/mibs) and make sure that the Zabbix server loads them (see Using and loading MIBs).
3. Restart your Zabbix server
4. Import the Template_SNMPv2_Livewire.xml into your Zabbix server.
5. Add the template to you host (or stack template)
6. Check if new data arrives

Notes

snmpwalk command

The following snmpwalk command might be helpful for debugging:

snmpwalk -v 2c -c public <HOST> TLS-SMI::livewire

Template SNMPv2 Livewire

Telos Alliance Livewire Audio over IP routing control based on TLS-LIVEWIRE-MIB.

Macros

• {$SNMP_COMMUNITY} (default: public)

Discovery

Livewire destinations (rabe.snmp.livewire.destinations.discovery)

Discovery of Livewire destinations.

Returns the following macros for each available Livewire destination

• {#DST_INDEX}
  • A unique value, greater than zero, for each destination (TLS-LIVEWIRE-MIB::dstIndex).
• {#DST_NAME}`
  • A textual string containing the label of the destination port (TLS-LIVEWIRE-MIB::dstName).

Item Prototypes

• Audio gain of destination port $1 (rabe.snmp.livewire.dstAudioGain[{#DST_INDEX}])
  Audio gain/attenuation trim [dB] of the destination port.
• Media address of destination port $1 (rabe.snmp.livewire.dstMediaAddress[{#DST_INDEX}])
  A textual string containing the destination media address (URI).
• Name of destination port $1 (rabe.snmp.livewire.dstName[{#DST_INDEX}])
  A textual string containing the label of the destination port.
• Number of audio channels of destination port $1 (rabe.snmp.livewire.dstNumberOfChannels[{#DST_INDEX}])
  The number of audio channels (0 - port not available, 1 - mono, 2 - stereo, 8 - 8-channel surround (5.1 + stereo)) of the destination port.
• Channel output mode of destination port $1 (rabe.snmp.livewire.dstOutputMode[{#DST_INDEX}])
  Channel output mode of destination port. Default mode is passing all channels. Mono destinations can be left-only, right-only or left+righ sum.

Livewire sources (rabe.snmp.livewire.sources.discovery)

Discovery of Livewire source ports.

Returns the following macros for each available Livewire source

• {#SRC_INDEX}
  • A unique value, greater than zero, for each source port (TLS-LIVEWIRE-MIB::srcIndex).
• {#SRC_NAME}`
  • A textual string containing the label of the source port (TLS-LIVEWIRE-MIB::srcName).

Item Prototypes

• Audio gain of source port $1 (rabe.snmp.livewire.srcAudioGain[{#SRC_INDEX}])
  Audio gain/attenuation trim [dB] of the source port.
• Enable status of source port $1 (rabe.snmp.livewire.srcEnable[{#SRC_INDEX}])
  Status of the source port, true(1) if the port is enabled, false(2) otherwise. A source port needs to be enabled in order to transmit multicast streams or accept unicast connections.
• Media address of source port $1 (rabe.snmp.livewire.srcMediaAddress[{#SRC_INDEX}])
  IPv4 multicast destination address for the RTP media stream, or empty (0.0.0.0) for unicast-only ports.
• Name of source port $1 (rabe.snmp.livewire.srcName[{#SRC_INDEX}])
  A textual string containing the label of the source port.
• Number of audio channels of source port $1 (rabe.snmp.livewire.srcNumberOfChannels[{#SRC_INDEX}])
  The number of audio channels (0 - port not available, 1 - mono, 2 - stereo, 8 - 8-channel surround (5.1 + stereo)) of the destination port.
• Packet size of source port $1 (rabe.snmp.livewire.srcPacketSize[{#SRC_INDEX}])
  The number of samples per each RTP media packet. Common values are:
• 12 - Livewire Livestreams (channels with mininum latency)
• 48 - AES67 1ms packet (low-latency, best interoperability)
• 240 - Livewire Standard Streams (least resource intensive)
