Come join our live training webinar every other Wednesday at 11am PST and hear LogicMonitor experts explain best practices and answer common questions. We understand these are uncertain times, and we are here to help!
Cisco UCS (Unified Computing System) is a data center product line composed of computing hardware, virtualization support, switching fabric, and management software. LogicMonitor gathers metrics for the system via the UCS Manager SOAP API. For more information on the metrics exposed via the API, see your API documentation, which is available at http://<your UCS Manager IP address>/docs.

UCS Manager is tied to a virtual IP address and the management database is replicated on the secondary Fabric Interconnect so failure of a single interconnect should not affect data collection.
As of early 2020, LogicMonitor’s Cisco UCS package is confirmed to be compatible with all current versions of Cisco UCS. As Cisco releases newer versions of UCS, LogicMonitor will test and extend coverage as necessary.
For each Cisco UCS system you are monitoring, you must add the following three resources into monitoring from within the LogicMonitor interface:
For more information on adding resources into monitoring, see Adding Devices.
LogicMonitor must provide credentials when accessing the UCS Manager API. These credentials should belong to an API user account that is assigned the read-only role. For security purposes, it is strongly recommended that the user account does not have privileges above read-only as the majority of other available roles can make configuration changes using the API. For more information on creating UCS user accounts, see the Cisco UCS Manager GUI Configuration Guide.
The following custom properties must be set on the Cisco UCS resources within LogicMonitor. For more information on setting properties, see Resource and Instance Properties.
From the LogicMonitor repository, import all Cisco UCS LogicModules, which are listed in the LogicModules in Package section of this support article. If you were previously running the now-deprecated SNMP-based Cisco UCS LogicModules, see the Migration from Legacy Cisco UCS DataSources section of this support article for details on how to safely migrate to the new Cisco UCS DataSources.
Once the LogicModules are imported (assuming all previous setup requirements have been met), the PropertySource will automatically assign the appropriate values to the system.categories property for your Cisco UCS resources. This, in turn, will automatically associate the DataSources and data collection will begin.
In June of 2020, LogicMonitor finalized a new suite of Cisco UCS DataSources. The new DataSources query the UCS Manager API for data, whereas the prior suite relied on an SNMP collection method. Gathering metrics via the API offers many advantages, including:
The release of the new API-based suite services to deprecate the legacy SNMP-based DataSources. The following table lists the deprecated SNMP modules and maps their functionality to the new API module(s).
If you are currently monitoring Cisco UCS devices using any of these legacy DataSources, you will not experience data loss upon importing the new DataSources. This is because DataSource names have been changed to eliminate module overwriting.
However, you will collect duplicate data and receive duplicate alerts for as long as both sets of DataSources are active. For this reason, we recommend that you disable the above-listed DataSources after importing the new set of DataSources and confirming that they are working as intended in your environment.
When a DataSource is disabled, it stops querying the host and generating alerts, but maintains all historical data. At some point in time, you may want to delete the legacy DataSources altogether, but consider this move carefully as all historical data will be lost upon deletion. For more information on disabling DataSources, see Disabling Monitoring for a DataSource or Instance.
LogicMonitor’s package for Cisco UCS consists of the following LogicModules. For full coverage, please ensure that all of these LogicModules are imported into your LogicMonitor platform.
When setting static datapoint thresholds on the various metrics tracked by this package’s DataSources, LogicMonitor follows the technology owner’s best practice KPI recommendations. If necessary, we encourage you to adjust these predefined thresholds to meet the unique needs of your environment. For more information on tuning datapoint thresholds, see Tuning Static Thresholds for Datapoints.
