D-Link standard SNMP

Plugin-Pack Assets​

Monitored Objects​

D-Link standard including CPU, Hardware, Interfaces, Memory, Stack.

The pack had been tested on following models: DGS-1510, DGS 3130, DGS-3630.

To control your D-Link equipment, the SNMP v2 must be configured.


  1. Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Network-Dlink-Standard-Snmp.noarch
  1. On the Centreon Web interface in "Configuration > Plugin packs > Manager", install the D-Link Network Plugin-Pack

Host configuration​

  • Add a new Host and apply the Net-Dlink-Standard-SNMP-custom Host Template
  • Fill the SNMP Version and Community fields according to the device's configuration

When using SNMP v3, use the SNMPEXTRAOPTIONS Host Macro to add specific authentication parameters

How to test the Plugin and what are the main options for ?​

Once the Plugin installed, log into your Centreon Poller CLI using the centreon-engine user account and test the Plugin by running the following command:

/usr/lib/centreon/plugins/ \
--plugin=network::dlink::standard::snmp::plugin \
--mode=cpu \
--hostname= \
--snmp-version='2c' \
--snmp-community='dlink_ro' \
--warning-average-5m='60' \
--critical-average-5m='75' \

Expected command output is shown below:

OK: 1 CPU(s) average usage is 16.00 % (5s) 14.00 % (1m) 14.00 % (5m) - CPU 'unit1~1' usage 16.00 % (5s) 14.00 % (1m) 14.00 % (5m) | 'cpu.utilization.5s.percentage'=16.00%;;;0;100 'cpu.utilization.1m.percentage'=14.00%;;;0;100 'cpu.utilization.5m.percentage'=14.00%;0:60;0:75;0;100 'unit1~1#core.cpu.utilization.5s.percentage'=16.00%;;;0;100 'unit1~1#core.cpu.utilization.1m.percentage'=14.00%;;;0;100 'unit1~1#core.cpu.utilization.5m.percentage'=14.00%;;;0;100

The command above monitors a D-Link cpu usage (--plugin=network::dlink::standard::snmp::plugin --mode=cpu) identified

by the IP address (--hostname= As the Plugin is using the SNMP protocol to request the device, the related community and version are specified (--snmp-version='2c' --snmp-community='dlink_ro').

This command would trigger a WARNING alarm if the CPU 5min average used to raise over 60% of the CPU capacity (--warning-average-5m='60') and a CRITICAL alarm over 75% (--critical-average-5m='75').

For each Plugin mode, all the options as well as all the available thresholds can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins/ \
--plugin=network::dlink::standard::snmp::plugin \
--mode=cpu \

UNKNOWN: SNMP GET Request : Timeout​

If you get this message, you're probably facing one of these issues:

  • The SNMP agent of the device isn't started or is misconfigured
  • An external device is blocking the request (firewall, ...)

UNKNOWN: SNMP GET Request : Cant get a single value.​

This error message often refers to the following issues:

  • The D-Link device doesn't support the MIB used by the plugin
  • The targeted SNMP OID cannot be fetched because of insufficient privileges on the device. SNMP Agent must be capable of accessing to the enterprise branch D-Link: .
