Description: Manages application-level attributes that typically require instrumentation within the managed application, extending the SYSAPPL-MIB with per-element channel and association details.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring APPLICATION-MIB with a free 30-day trial of IPNetwork Monitor.

What Is APPLICATION-MIB?

APPLICATION-MIB is an IETF standards-based MIB that models generic aspects of running applications for management purposes, complementing the System Application MIB (SYSAPPL-MIB) with objects requiring in-application instrumentation. It exposes mapping tables between application server names, service instances, and running application elements -- e.g., which server name corresponds to which service instance and which running element backs a given instance. It is used to monitor the software-level status of distributed application components -- confirming which application instances are actively bound to which named services, essentially a service/process discovery and status mechanism -- rather than hardware health. It explicitly extends SYSAPPL-MIB, from which it inherits the notion of "application elements," and is part of the broader IETF Application Management MIB family. It is typically deployed in enterprise systems-management platforms monitoring distributed, multi-tier application deployments for service discovery and health correlation, making this APPLICATION-MIB reference a standard companion to SYSAPPL-MIB in such platforms.

IPNetwork Monitor allows you to monitor SNMP objects defined in APPLICATION-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

  • vendor-neutral, standards-based IETF MIB, not tied to a specific manufacturer
  • servers running managed distributed applications

Monitoring Examples

An admin could walk applSrvNameToSrvInstTable/applSrvNameToSrvInstEntry to map a known service name to its applSrvInstance identifiers, then cross-reference applSrvInstToRunApplElmtTable to find which running application element backs that instance. If a service name in applSrvNameToSrvInstTable no longer resolves to any entry in applRunApplElmtToSrvInstTable, that indicates the backing application process has stopped or failed to register, a useful signal for detecting an application-level outage.

What Can Be Monitored

  • service name to service instance mapping
  • service instance to running application element mapping
  • application instance registration status
  • running application element identity

How to Use in IPNetwork Monitor

Example using applOpenChannelReadRequests OID:

Select a Servers running managed distributed application as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type applOpenChannelReadRequests into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This attribute reports the number of read requests for this channel. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline (in read requests), since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
