].

Prerequisitesβ
To control your D-Link equipment, the SNMP v2 must be configured.
Setupβ
- Online License
- Offline License
- Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Network-Dlink-Standard-Snmp.noarch
- On the Centreon Web interface in "Configuration > Plugin packs > Manager", install the D-Link Network Plugin-Pack
- Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Network-Dlink-Standard-Snmp.noarch
- On the Centreon Central server, install the Centreon Plugin-Pack from the RPM:
yum install network-dlink-standard-snmp.noarch
- On the Centreon Web interface in "Configuration > Plugin packs > Manager", install the D-Link Network Plugin-Pack
Host configurationβ
- 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
Mandatory | Name | Description |
---|---|---|
SNMPEXTRAOPTIONS | Configure your own SNMPv3 credentials combo |
FAQβ
How to test the Plugin and what are the main options for ?β
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/centreon_dlink_standard_snmp.pl \
--plugin=network::dlink::standard::snmp::plugin \
--mode=cpu \
--hostname=10.30.2.114 \
--snmp-version='2c' \
--snmp-community='dlink_ro' \
--warning-average-5m='60' \
--critical-average-5m='75' \
--verbose
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 10.30.2.114 (--hostname=10.30.2.114
). 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/centreon_dlink_standard_snmp.pl \
--plugin=network::dlink::standard::snmp::plugin \
--mode=cpu \
--help
UNKNOWN: SNMP GET Request : Timeoutβ
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.β
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: .1.3.6.1.4.1.171.
