Prerequisites​

To control your Dell OS10 equipment, the SNMP v2 must be configured. For more information, please refer to the official user documentation : https://www.dell.com/support/manuals/fr/fr/frbsdt1/networking-z9100/os10-enterprise-user-guide-10_4_2-pub/configure-snmp?guid=guid-cf75b1b6-5c24-4237-af0c-b9ed1f491b75&lang=en-us

Setup​

  1. Install the Centreon Plugin on every Poller monitoring Dell OS10 resources:
yum install centreon-plugin-Network-Dell-Os10-Snmp.noarch
  1. On the Centreon Web interface in "Configuration > Plugin packs > Manager", install the Dell OS10 SNMP Plugin-Pack

Host configuration​

  • Add a new Host and apply the Net-Dell-Os10-SNMP-custom Host Template
  • Fill the SNMP Version and Community fields according to the device's configuration

FAQ​

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/centreon_dell_os10_snmp.pl \
--plugin=network::dell::os10::snmp::plugin \
--mode=cpu \
--hostname=10.30.2.114 \
--snmp-version='2c' \
--snmp-community='dell_os10_ro' \
--warning-average='60' \
--critical-average='75' \
--verbose

Expected command output is shown below:

OK: CPU(s) average usage is 15.29 % - CPU '0' usage : 15.29 % 
| 'total_cpu_avg'=15.29%;0:60;0:75;0;100 'cpu'=15.29%;;;0;100

The command above monitors a Dell OS10 cpu usage (--plugin=network::dell::os10::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='dell_os10_ro').

This command would trigger a WARNING alarm if the CPU average used to raise over 60% of the CPU capacity (--warning-average='60') and a CRITICAL alarm over 75% (--critical-average='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_dell_os10_snmp.pl 
--plugin=network::dell::os10::snmp::plugin \
--mode=cpu \
--help

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 Dell 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 Dell: 1.3.6.1.4.1.674.
