Description: Manages host OS image policies (type, composition, distribution) assigned to Cisco UCS service profiles for automated server provisioning
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is CISCO-UNIFIED-COMPUTING-HOSTIMG-MIB?
CISCO-UNIFIED-COMPUTING-HOSTIMG-MIB belongs to the Cisco UCS Manager SNMP MIB suite and models host image policies -- the OS distribution, image type, and composition settings that UCS Manager pushes to blade or rack servers via service profiles. It exposes configuration data describing which OS image/distro (via cucsHostimgPolicyDistro and cucsHostimgPolicyType) is bound to a policy, along with descriptive metadata and internal identifiers. Rather than hardware counters, its monitoring value lies in tracking software provisioning state -- verifying which OS image version a policy directs to a server, useful for auditing consistent software versions across a server fleet and catching drift from an intended golden image. As with other UCS MIBs it depends on the shared UCS Manager distinguished-name object model and is typically queried alongside service profile and boot policy MIBs. It is deployed in data centers using Cisco UCS Manager for bare-metal or automated OS provisioning of blade/rack servers, where CISCO-UNIFIED-COMPUTING-HOSTIMG-MIB SNMP monitoring helps confirm every profile still points to the intended golden image.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-UNIFIED-COMPUTING-HOSTIMG-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Cisco UCS Manager (blade and rack servers)
Monitoring Examples
Polling cucsHostimgPolicyTable/cucsHostimgPolicyEntry exposes cucsHostimgPolicyName, cucsHostimgPolicyDistro, and cucsHostimgPolicyType so an admin can confirm which OS image is configured for a given policy. cucsHostimgPolicyComp and cucsHostimgPolicyConf describe the image composition/configuration package assigned, letting an operator audit whether service profiles all reference the intended golden image version rather than an outdated one.
What Can Be Monitored
- assigned OS image/distro per policy
- image type and composition
- policy description and identifiers
- software version consistency across profiles
