NFS / RPC Statistics Attributes

The NFS / RPC Statistics group attributes refer to Network File System and Remote Procedure Call call rates and errors. These attributes fall into four subgroups:


NFS Client Calls The number of calls made to a server during a monitoring interval. Valid entry is an integer in the range 0 to 9999. Use this attribute to show the amount of NFS traffic. If the value is high, it may mean a client is flooded with call requests.

NFS Client Calls-Rejected The number of calls rejected by a server during a monitoring interval. Valid entry is an integer in the range 0 to 200. Use this attribute in conjunction with the NFS Client Calls attribute to determine the proportion of calls rejected by the NFS server.

NFS Client File Creates The number of File Creates calls made to a server during the monitoring interval. Valid entry is an integer in the range 0 to 9999. Use this attribute with other Call-type attributes for analyzing NFS traffic and correcting problems on your network.

NFS Client File System Statistics Calls The number of file statistics calls made within the monitoring interval. Valid entry is an integer in the range 0 to 9999. Use this attribute with other Call-type attributes for analyzing NFS traffic and correcting problems on your network.

NFS Client Get Attribute Calls The number of calls made to determine what type of file is being called. For example, a text file or an executable file. Valid entry is an integer in the range 0 to 9999. Use this attribute with other Call-type attributes for analyzing NFS traffic and correcting problems on your network.

NFS Client Link Calls The number of hard link reports made by a server during a pre-defined time interval. Valid entry is an integer in the range 0 to 9999. Use this attribute with other Call-type attributes for analyzing NFS traffic and correcting problems on your network.

NFS Client Rejected Call Percentage The percentage of NFS calls rejected by a server during a monitoring interval. Valid entry is an integer in the range 0 to 100. Use this attribute to monitor unacceptable rates of NFS call rejection and to determine whether the server or a particular client is causing network problems. If the server is experiencing problems, all calls will be rejected. If a client is experiencing problems, it along will have its calls rejected. The rejection percentage may increase dramatically after reaching a critical threshold, since rejections require re-transmission.

RPC Client Calls Rejected by Server The number of calls made by a client to a server that the server rejected, during a monitoring interval. Valid entry is an integer in the range 0 to 200. Use this attribute in conjunction with the Calls attribute to determine the proportion of calls rejected by the RPC server. If the value is high, it may mean there is excessive noise on the network, which causes bad datagrams to occur, or a server may be flooded with call requests.

RPC Client Calls Retransmitted The number of RPC packets retransmitted to an RPC server during a monitoring interval. Valid entry is an integer in the range 0 to 200. Use this attribute to determine if a large number of calls are being retransmitted. If so, your server may be overworked or there may be a network problem.

RPC Client Calls Timed Out The number of times an RPC call from the managed system timed out before the RPC server replied. Valid entry is an integer in the range 0 to 200. Use this attribute to determine if the server is failing to acknowledge calls received. If the server is overworked, you may need to re-route network traffic.

RPC Client Replies Not Matching Calls The number of times the managed system received replies from an RPC server that did not match calls. Valid entry is an integer in the range 0 to 200. Use this attribute to determine if a reply or acknowledgment from the server matches a request made by a client. A failure to match the request may mean there is noise on the network.

RPC Client Times Authentication Refreshed The number of times the managed system had to resend the authentication information for an RPC call during the monitoring interval. Valid entry is an integer in the range 0 to 9999. Use this attribute to count the number of times an authorization is refreshed. This attribute helps you verify client authorization for making a request by periodically requesting an electronic handshake from the client.

RPC Client Times Call Wait On Busy The number of times the initial bind for an RPC call from the managed system had to wait because of a busy server. Valid entry is an integer in the range 0 to 200. Use this attribute to show the amount of NFS traffic. When a client sends a call request to a server, it gives the server a certain amount of time to respond before re-sending the call. The amount of time varies from system to system. If the Times Call Wait On Busy value is high, it may indicate that the server is overworked. You may want to re-route call requests to another server.

RPC Server Calls Rejected The number of RPC calls from the managed system that were rejected by a server during a monitoring interval. Valid entry is an integer in the range 0 to 200. Use this attribute to determine if the server is rejecting a large number of calls. If only a few calls are being rejected, it may be a client-specific problem. If many calls are being rejected, it may be a problem with your server.

RPC Server Packets Too Short The number of incomplete RPC packets that were too short in length received by a server during a monitoring interval. Valid entry is an integer in the range 0 to 200. Use this attribute to determine if the server is having problems processing packet data. If the packet size does not match the size stated in the packet header, there may be noise on the system.

RPC Server Packets with Malformed Header The number of RPC packets that had malformed headers and were received by the server during a monitoring interval. Valid entry is an integer in the range 0 to 9999. Use this attribute to determine if there is noise on the system. The server cannot validate a packet or where it came from if, due to a malformed header, it cannot acknowledge the sender. This decreases the efficiency of the network. Try checking server connections. Another cause may include extraneous network noise.

RPC Server Times RPC Packet Unavailable The number of times a server attempted to receive a packet when none was available, during a monitoring interval. Valid entry is an integer in the range 0 to 200.

System Name The name of the RPC system you are monitoring. Valid entry is a simple text string, alphanumeric with a maximum length 64 characters.

Timestamp The date and time the agent collects information as set on the monitored system. The timestamp format for SCAN and STR functions is CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:

C = Century (0 for 20th, 1 for 21st)

Y = Year

M = Month

D = Day

H = Hour

M = Minute

S = Second

m = millisecond
