zabbix-arris-sb6190

Zabbix template for monitoring ARRIS SB6190 SURFBoard Cable Modems Additionally may support SB6183 although not tested by me

The default trigger values and graph limits are based on:

• ARRIS SB6190: CABLE SIGNAL LEVELS
• DSLReports Modems FAQ

Dependencies

• curl
• gawk
• html-xml-utils (for hxnormalize & hxselect)
• sed
• xmlstarlet

Installation

• Copy the scripts to your Zabbix ExternalScripts location (default: /usr/lib/zabbix/externalscripts)
• Make sure the script permissions allow the zabbix server to execute them
• Import the template file into the Zabbix UI

Setup and Configuration

• Create a new host "Cable Modem"
• Link the new host to the template
• If modem is not using 192.168.100.1 create a host macro {$MODEM_ADDRESS} to set a custom IP address
• In Monitoring->Latest Data validate that the "Check Status" item has valid results

What is Provided

Out of the box the template has a number of items, triggers, and graphs as well as discovery rules to provide individual channel details

Template Items

• Check Status (5min refresh, text of status results)

  • Boot (last value from config screen)
  • Configuration (last value from config screen)
  • Connectivity (last value from config screen)
  • Downsteam Channels (count)
  • Downstream Power (min/avg/max)
  • Downstream SNR (min/avg/max)
  • Downstream Corrected Errors (total accross all channels)
  • Downstream Uncorrectable Errors (total accross all channels)
  • Upstream Channels (count)
  • Upstream Power (min/avg/max)
  • Upstream Symbol Rate (min/avg/max)

• Ping (30sec refresh)

  • Simple up/down check
  • Response time

Template Triggers

Trigger values are based on template macros so they can be overriden locally

• Downstream Channel MISSING
• Downstream Power(avg) LOW
• Downstream Power(avg) HIGH
• Downstream SNR(avg) LOW
• Downstream Corrected Errors large increase
• Downstream Uncorrectable Errors large increase
• Upstream Channel MISSING
• Upstream Power(avg) LOW
• Upstream Power(avg) HIGH
• Ping HIGH LATENCY
• Ping offline

Template Graphs

• Downstream Channels (count)
• Downstream Power
• Downstream SNR
• Corrected Errors
• Uncorrectable Errors
• Upstream Channels (count)
• Upstream Power
• Upstream Symbol Rate
• Ping Response Time

All 9 graphs are included on a monitoring screen as well

Downstream Channel Discovery

Downstream channel discovery is run once a day and parses the status page information to create a list of channels. Each channel has items, triggers and graphs created.

Downstream Channel Items

• Status
• Modulation (64QAM, 256QAM, etc)
• Frequency (MHz)
• Power (dBmV)
• SNR (dB)
• Corrected Errors
• Uncorrectable Errors

Downstream Channel Triggers

Trigger values are based on template macros so they can be overriden locally

• Power LOW
• Power HIGH
• SNR LOW

Downstream Channel Graphs

• Power
• SNR

Upstream Channel Discovery

Upstream channel discovery is run once a day and parses the status page information to create a list of channels. Each channel has items, triggers and graphs created.

Upstream Channel Items

• Status
• Channel Type (ATDMA, etc)
• Frequency (MHz)
• Power (dBmV)
• Symbol Rate (kSym/s)

Upstream Channel Triggers

Trigger values are based on template macros so they can be overriden locally

• Power LOW
• Power HIGH

Upstream Channel Graphs

• Power
• Symbol Rate
