Prerequisites

Dell Xseries Device configuration

The SNMP v2 agent has to be configured on the Dell Xseries device.

Network flow

The Centreon Poller should be able to reach the UDP/161 SNMP port of the Dell Xseries device.

Installation

Online IMP Licence & IT-100 Editions
Offline IMP License
  1. Install the Plugin on every poller expected to monitor Dell Xseries resources:
yum install centreon-plugin-Network-Switch-Dell-Xseries-Snmp
  1. Install the Dell Xseries Centreon Plugin-Pack from the "Configuration > Plugin packs > Manager" page
  1. Install the Plugin on every poller expected to monitor Dell Xseries resources:
yum install centreon-plugin-Network-Switch-Dell-Xseries-Snmp
  1. Install the Centreon Plugin-Pack RPM on the Centreon Central server:
yum install centreon-pack-network-switch-dell-xseries-snmp
  1. Install the Dell Xseries Centreon Plugin-Pack from the "Configuration > Plugin packs > Manager" page

Configuration

  • In the Centreon Web interface, add a new Host from the "Configuration > Hosts" page.
  • Set the values of the SNMP community and SNMP version fields then apply the Net-Switch-Dell-Xseries-SNMP-custom Host template.

If you're using the version 3 of the SNMP protocol, select the related SNMP version in the Host configuration form and set the SNMP v3 specific settings in the SNMPEXTRAOPTIONS Macro:

MandatoryNameDescription
SNMPEXTRAOPTIONSExtra options SNMP of Dell Xseries

FAQ

How can I test the Plugin in the CLI and what do the main options mean?

Once the Plugin is installed, you can test it directly from the command line interface of the Centreon Poller with the centreon-engine user:

/usr/lib/centreon/plugins/centreon_dell_xseries_snmp.pl \
    --plugin=network::dell::xseries::snmp::plugin \
    --hostname=10.0.0.1 \
    --snmp-version='2c' \
    --snmp-community='public' \
    --mode=cpu \
    --warning-average-1s='80' \
    --critical-average-1s='90' \
    --warning-average-1m='80' \ 
    --critical-average-1m='90' \
    --verbose

The expected result should output something similar to:

OK: cpu total: 15 % average-1s: 18.00% average-1m: 25.00% average-5m: 15.00%|
'cpu.utilization.1s.percentage'=18%;80;90;0;100; 'cpu.utilization.1m.percentage'=25%;80;90;0;100; 'cpu.utilization.1s.percentage'=15%;;;0;100

The above command checks a Dell Xseries switch using the SNMP protocol (--plugin=network::dell::xseries::snmp::plugin) with the public community (--snmp-community='public') and the 2c SNMP version (--snmp-version='2c'). This command checks the current CPU average of the switch (--mode='cpu').

This command will trigger a WARNING alarm if the average usage on a 1s period increases over 80% (--warning-average-1s='80')

and a CRITICAL alarm over 90% (--critical-average-1s=90).

Alert thresholds can be defined for all metrics collected using the options --warning-* and --critical-*, for example: --warning-average-1m='80'' --critical-average-1m='90''.

The syntax of the different options of the thresholds as well as the list of the options and their usage are detailed in the help of the mode by adding the parameter --help to the command:

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

You can display all of the modes that come with the Plugin with the command below:

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

UNKNOWN: SNMP GET Request : Timeout

If you get this message, it means that the Centreon poller is unable to contact the Dell Xseries device on UDP port 161 or that the configured SNMP community is not correct. It is also possible that a firewall is blocking the flows.

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

This error message often refers to the following problems:

  • The Dell Xseries device does not support the MIB used by the Plugin.
  • The targeted SNMP OID cannot be recovered due to insufficient device privileges. The SNMP agent must be able to access the Dell enterprise branch: .1.3.6.1.4.1.674.
