Description: Provides NFS protocol statistics including RPC call rates and error counts via Sun Management Center.

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 NFSSTAT-SUNMANAGEMENTCENTER-MIB2?

This MIB, delivered via Sun Management Center, exposes NFS and underlying RPC protocol statistics for both server and client roles on Sun/Solaris systems. It provides counters for total RPC calls, bad/failed RPC calls and their percentage, and RPC call rate, mirrored by equivalent NFS-specific call counters, separately for the server side and the client side of the host. Its monitoring value is software/service performance status: a rising nfssServPcntBadRPCCalls or nfssServPcntBadNFSCalls indicates NFS service degradation such as version mismatches, timeouts, or server overload, while nfssServRPCCallRate/nfssServNFSCallRate and their client counterparts show load trends useful for capacity planning and detecting stalled NFS mounts. It is built as an NFS/RPC statistics extension within the Sun Management Center (sunsymon) private enterprise MIB tree, layered over the standard NFS/RPC protocol stack rather than another SNMP MIB. It is deployed on Sun/Solaris servers and clients managed by Sun Management Center in environments relying on NFS file sharing. Engineers can download the NFSSTAT-SUNMANAGEMENTCENTER-MIB2 file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NFSSTAT-SUNMANAGEMENTCENTER-MIB2. 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

Sun/Solaris NFS server
Sun/Solaris NFS client

Monitoring Examples

An admin monitoring an NFS file server would watch nfssTotServRPCCalls and nfssServBadRPCCalls together with nfssServPcntBadRPCCalls to detect a rising error rate, and nfssServRPCCallRate to see if the server is experiencing an unusual load spike. On the client side, nfssCliTotRPCCalls, nfssCliBadRPCCalls, and nfssCliPcntBadRPCCalls would be checked when a client application reports slow file access, since a high client-side bad-call percentage points to a server-side or network problem rather than a client misconfiguration. nfssServTotNFSCalls versus nfssServBadNFSCalls specifically isolates NFS-level errors from generic RPC transport errors.

What Can Be Monitored

server-side RPC call counts and error rate
server-side NFS call counts and error rate
client-side RPC call counts and error rate
RPC/NFS call rate (server and client)

How to Use in IPNetwork Monitor

Example using nfssTotServRPCCalls OID:

Select a Sun/Solaris NFS server/client (Sun Management Center) 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 nfssTotServRPCCalls into the Find box to locate it in the OID tree, then select it and click OK. It reports the total number of RPC server calls received by the host since last init. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
