Description: Monitors NFS server and client statistics including mount points, operations, and error counts.

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 TUBS-IBR-NFS-MIB?

TUBS-IBR-NFS-MIB is an experimental, vendor-neutral research MIB from TU Braunschweig's Institute of Operating Systems (IBR) for monitoring NFS (Network File System) servers and clients. It exposes operation-level counters for both server and client roles, breaking down calls by NFS procedure type such as getattr, setattr, lookup, read, write, and create, plus bad/error and null call counts. Its primary monitoring value is software/service status: it lets an administrator see whether the NFS service on a host is actively serving requests, which operation types dominate load, and whether error rates (nfsServerBad) signal client misconfiguration or server trouble. As an experimental MIB it has no formal dependency chain beyond standard SNMPv2 conventions, though it conceptually mirrors the data in the classic NFS/RPC statistics exposed by rpc.nfsstat. It was used in academic/research network monitoring contexts to profile NFS traffic and troubleshoot file-sharing performance. Engineers can download the TUBS-IBR-NFS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TUBS-IBR-NFS-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 MIB, not tied to a specific manufacturer
  • NFS server or NFS client host

Monitoring Examples

An administrator would poll nfsServerCalls alongside nfsServerRead and nfsServerWrite to see the total request volume and read/write mix on an NFS server, and compare that to nfsServerBad to spot a rising error rate indicating stale file handles or permission issues. Watching nfsServerLookup and nfsServerGetattr helps reveal whether clients are hammering the server with metadata operations rather than actual data transfer, a common sign of an inefficient client cache. The nfsClient subtree provides the mirrored per-operation counters for the client side of the same host.

What Can Be Monitored

  • total NFS server calls
  • NFS read/write operation counts
  • NFS error (bad call) counts
  • lookup and getattr operation rates
  • NFS client operation statistics

How to Use in IPNetwork Monitor

Example using nfsServerCalls OID:

Select a device implementing TUBS-IBR-NFS-MIB 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 nfsServerCalls into the Find box to locate it in the OID tree, then select it and click OK. The number of nfs calls received by the server. 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 Counter32-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, 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.
