Cisco UCS


Cisco Unified Computing System (UCS) is a system of servers, a network, storage and a storage network in a single platform.

The Centreon Monitoring Connector Cisco UCS relies on the SNMP protocol to query and collect status and metrics of the UCS server.

Collected metrics​

Metric nameDescriptionUnit of audit logscount
audit.cleared.countNumber of cleared audit logscount of info audit logscount
audit.condition.countNumber of condition audit logscount
audit.warning.countNumber of warning audit logscount
audit.minor.countNumber of minor audit logscount
audit.critical.countNumber of critical audit logscount


Device Configuration​

The SNMP agent must be configured and running on the UCS server. Please refer to the manufacturer documentation to achieve this.

Network flows​

The Centreon Poller must be able to reach the UDP/161 SNMP port of the UCS server.


  1. Install the Centreon package on every Centreon Poller expected to monitor UCS servers:
yum install centreon-plugin-Hardware-Servers-Cisco-Ucs-Snmp
  1. On the Centreon Web interface, install the Cisco UCS Monitoring Connector through Configuration > Monitoring Connector Manager page.

Host configuration​

Create your Host and apply the HW-Server-Cisco-Ucs-custom Host Template. You must set SNMP Community and Version in the dedicated fields of the Host Form.

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

How to test my plugin and what do the main parameters stand for ?​

Once the plugin is installed, you can test it logging into the CLI with the centreon-engine user.

/usr/lib/centreon/plugins// \
--plugin=hardware::server::cisco::ucs::plugin \
--mode=faults \
--hostname= \
--snmp-version='2c' \
--snmp-community='cisco_ucs' \
--filter-severity='critical|major=critical' \
--filter-severity='warning|minor=warning' \

The above command checks for faults on a UCS server (--mode=faults). Mandatory options are the IP/FQDN of the device

(--hostname= and the SNMP version you have set on your appliance (--snmp-community='cisco_ucs').

This command would trigger a WARNING alarm if a problem with the severity WARNING or MINOR is detected on a UCS server resource (--filter-severity='warning|minor=warning') and

a CRITICAL alarm if a problem is detected with the severity CRITICAL or MAJOR (--filter-severity='critical|major=critical').

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

/usr/lib/centreon/plugins// \
--plugin=hardware::server::cisco::ucs::plugin \
--mode=faults \

All plugin modes can be listed with the following command:

/usr/lib/centreon/plugins// \
--plugin=hardware::server::cisco::ucs::plugin \


UNKNOWN: SNMP GET Request : Timeout​

If you get this error, it may indicate that some flows are blocked between the Centreon Poller and the UCS server.

It can also mean that the Centreon Host Configuration doesn't reflect the SNMP configuration on UCS side (version, community).

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

You may get this error when SNMP privileges are not wide enough. You can check that the SNMP community used in your command line has enough rights to walk the Cisco UCS SNMP branch: .

You can use the snmpwalk utilities which is provided through net-snmp package.
