Description: IBM MIB for the Open Systems Adapter (OSA) network interface on IBM zSeries mainframes providing channel and interface statistics.

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 IBM-OSA-MIB?

This is an IBM enterprise MIB for the Open Systems Adapter (OSA) network interface feature on IBM zSeries/System z mainframes, which provides LAN connectivity (Ethernet/token ring) channel attachment for the mainframe. Its two top-level branches, ibmOSAMibObjects and ibmOSAMibConformance, indicate it defines OSA-Express card management objects alongside a conformance/compliance statement, though the sample list here doesn't expose the underlying data tables directly. Such adapter MIBs are used to monitor the hardware and channel status of OSA-Express feature cards—covering things like port/channel operational state, interface statistics, and adapter identification—so mainframe network staff can detect a failed or degraded OSA card without needing to be on the mainframe console. It is an IBM-specific extension that typically complements standard IF-MIB interface objects, since OSA ports appear as network interfaces to the host TCP/IP stack. It is deployed exclusively on IBM zSeries/System z mainframes using OSA-Express network adapters for LAN attachment, and administrators can download the IBM-OSA-MIB file to load into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in IBM-OSA-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

  • IBM zSeries/System z mainframes with OSA-Express adapters

Monitoring Examples

The visible object tree here is limited to the top-level ibmOSAMibObjects and ibmOSAMibConformance groupings, so this excerpt doesn't expose specific runtime tables; in practice under ibmOSAMibObjects one would expect per-adapter/port status and statistics objects, but no such table or column names are confirmed from the sample provided.

What Can Be Monitored

  • OSA adapter/channel operational status
  • adapter identification/inventory
