Prerequisites

SNMP Configuration

To use this Pack, the SNMP service must be properly configured on your device.

Network flow

The target equipment must be reachable from the Centreon Poller on the UDP/161 SNMP port.

Setup

Online License
Offline License

Install the Centreon plugin package on every Centreon poller expected to monitor Dell N-series SNMP resources:

yum install centreon-plugin-Network-Dell-Nseries-Snmp

On the Centreon web interface, install the Dell N-series SNMP Centreon Pack on the Configuration > Plugin Packs page.

Install the Centreon plugin package on every Centreon poller expected to monitor Dell N-series SNMP resources:

yum install centreon-plugin-Network-Dell-Nseries-Snmp

Install the Dell N-series SNMP Centreon Pack RPM on the Centreon Central server:

yum install centreon-pack-network-dell-nseries-snmp

On the Centreon web interface, install the Dell N-series SNMP Centreon Pack on the Configuration > Plugin Packs page.

Configuration

Host

Log into Centreon and add a new host through Configuration > Hosts.
Fill the Name, Alias & IP Address / DNS fields according to your Dell N-series SNMP equipment settings.
Apply the Net-Dell-Nseries-SNMP-custom template to the host.
Once the template is applied, fill in the corresponding macros. Some macros are mandatory.

When using SNMP v3, use the SNMPEXTRAOPTIONS Macro to add specific authentication parameters More information in the Troubleshooting SNMP section.

Mandatory	Name	Description
	SNMPEXTRAOPTIONS	(Default: 'Configure your own SNMPv3 credentials combo')

How to check in the CLI that the configuration is OK and what are the main options for?

Once the plugin is installed, log into your Centreon poller's CLI using the centreon-engine user account (su - centreon-engine) and test the plugin by running the following command:

/usr/lib/centreon/plugins/centreon_dell_nseries_snmp.pl \
    --plugin=network::dell::nseries::snmp::plugin \
    --mode=cpu \
    --hostname=10.0.0.1 \
    --snmp-version='2c' \
    --snmp-community='my-snmp-community' \
    --warning='' \
    --critical=''

The expected command output is shown below:

OK: CPU Usage: 44.13%% (5sec), 34.23%% (1min), 24.10% (5min) | 'cpu.utilization.5s.percentage'=44.13%;;;0;100 'cpu.utilization.1m.percentage'=34.23%;;;0;100 'cpu.utilization.5m.percentage'=24.10%;;;0;100 

All available options for a given mode can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins/centreon_dell_nseries_snmp.pl \
    --plugin=network::dell::nseries::snmp::plugin \
    --mode=cpu \
    --help

All available modes can be displayed by adding the --list-mode parameter to the command:

/usr/lib/centreon/plugins/centreon_dell_nseries_snmp.pl \
    --plugin=network::dell::nseries::snmp::plugin \
    --list-mode
