Description: Monitors NFS file system mount status, RPC call statistics, and server performance counters.

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-NFS-MIB?

TUBS-NFS-MIB is an experimental MIB from TU Braunschweig's IBR institute for monitoring an NFS (Network File System) server's request-handling behavior. It exposes RPC call statistics broken out by NFS operation type, such as attribute lookups, reads, writes, and file creation, along with total and failed-call counts. Its monitoring value is software/service status: administrators use it to gauge NFS server load by operation mix and to catch a rising rate of bad or failed calls, which signals client-facing errors such as permission problems or stale file handles. It conceptually parallels the standard `nfsstat` statistics model and is part of the same TUBS-IBR experimental MIB series as TUBS-PROC-MIB and TUBS-IBR-LINUX-NETFILTER-MIB. It is deployed on Unix/Linux NFS servers in academic and enterprise file-sharing environments, where TUBS-NFS-MIB SNMP monitoring highlights operation mix and rising failed-call rates.

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

Unix/Linux NFS server

Monitoring Examples

nfsServerCalls reports the total NFS RPC call count while nfsServerBad tracks failed calls; per-operation counters such as nfsServerRead, nfsServerWrite, nfsServerLookup, and nfsServerCreate let an admin see which NFS operations dominate server load. A rising nfsServerBad count relative to nfsServerCalls would indicate client requests failing against an export, worth investigating for permission errors or stale file handles.

What Can Be Monitored

total NFS RPC calls
failed/bad call count
per-operation call counters (read, write, lookup, create, etc.)
client vs. server call statistics

How to Use in IPNetwork Monitor

Example using nfsServerCalls OID:

Select an Unix/Linux NFS server (per-operation RPC call/failed-call counter status) 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.
