Description: Provides managed objects for host resource monitoring (CPU, memory, storage, processes) on Juniper Networks routing platforms.

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 JUNIPER-HOSTRESOURCES-MIB?

JUNIPER-HOSTRESOURCES-MIB is a Juniper Networks enterprise MIB that extends the standard IETF HOST-RESOURCES-MIB (RFC 2790) to add Juniper-specific host-resource data for the Routing Engine or control-plane processor on Juniper platforms. It provides visibility into system resource consumption such as CPU utilization, memory usage, storage, and running processes on the device's internal host operating system. This is a core software/hardware health MIB: it is exactly the kind of module used to monitor CPU load, memory pressure, and process status on the routing engine, which are classic indicators of device stress, memory leaks, or a hung software process. Its explicit dependency is on the standard HOST-RESOURCES-MIB, which it augments rather than replaces, so it should be polled in conjunction with that base MIB. Typical deployment is any Juniper router or switch where administrators need OS-level resource monitoring of the control plane in addition to network-specific metrics. Engineers can download the JUNIPER-HOSTRESOURCES-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-HOSTRESOURCES-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

  • Juniper router
  • Juniper switch (Routing Engine/control plane)

Monitoring Examples

An administrator would poll the extended CPU and memory objects alongside the standard hrProcessorLoad and hrStorageTable from HOST-RESOURCES-MIB to detect a Routing Engine running low on memory or pegged at high CPU, which often precedes control-plane instability or slow BGP convergence. No sample objects were extracted for this specific extension module, so the exact Juniper-added object names are unconfirmed, but its stated purpose is to extend host-resource reporting beyond the base standard. This MIB is primarily used for control-plane resource-health monitoring rather than line-card or interface-level data.

What Can Be Monitored

  • CPU utilization
  • memory usage
  • storage usage
  • running processes

How to Use in IPNetwork Monitor

Example using jnxHrStoragePercentUsed OID:

Select a Juniper router/switch (Routing Engine/control-plane host resources) 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 jnxHrStoragePercentUsed 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. The amount of the storage represented by this entry that is allocated, as a percentage of the total amount available. 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 Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drifts significantly from its normal baseline, since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.
