NAME

snmpxperfmon − SNMP application for monitoring network interfaces

SYNOPSIS

snmpxperfmon agent [ qualifiers ] [options]

DESCRIPTION

snmpxperfmon is a tool that monitors network interfaces and displays the status of packets transferred through them as line graphs.  The agent that is monitored is specified on the command line.  snmpxperfmon monitors the number of bytes and packets input and output via all of the agent’s network interfaces.  The graphs show the average number of bytes and packets transferred per second.  If values exceed the graphs’ display range, snmpxperfmon automatically adjusts ranges to accommodate them. 

agentThe agent should be specified as an address in dot notation, such as 133.138.1.1, or as a hostname. 

qualifiers
The following qualifiers are used to specify the data to be monitored.

inputDisplays the number of packets and bytes of data input. 

outputDisplays the number of packets and bytes of data output. 

bytesDisplays only the number of bytes of data input and output. 

packetsDisplays only the number of packets of data input and output. 

Multiple qualifiers can be combined, as in input bytes.  If, for example, input bytes is specified, snmpxperfmon displays the number of bytes of data input to the agent’s network interfaces.  If bytes is specified for an agent for which it is not possible to monitor the number of bytes, snmpxperfmon will attempt to monitor the number of bytes and then automatically switch to displaying the number of packets instead.  If neither bytes nor packets is specified for such an agent, snmpxperfmon will attempt to monitor the number of bytes and packets and then automatically switch to displaying the number of packets only.  Menu bar in the snmpxperfmon window permits the user to change the operating conditions, display the online manual, etc.  The options available from the menu bar are as follows.  File

Control...
This item is used to pop up the control panel to change the polling interval. The polling interval specifies the number of seconds which must elapse between the sending of value queries to the agent. The default value for the polling interval is 60 seconds.

Exit
Exits snmpxperfmon.

OPTIONS

In addition to the standard X Toolkit options, snmpxperfmon also supports the following.  −interval seconds
−i seconds

The integer value seconds is used as the polling interval.  This value specifies the number of seconds which must elapse between the sending of value queries to the agent by snmpxperfmon.  The default value for the polling interval is 60 seconds. 

−community name
−c name

The community name used when snmpxperfmon accesses the agent is specified using name.  The default community name is “public”. 

−help

Displays a description of the options unique to snmpxperfmon. 

RESOURCES

snmpxperfmon supports all of the standard resource names and class names included in X Toolkit.  In addition, the following application resources may be used.  The default values are shown below. 

Snmpxperfmon.interval: 60
Snmpxperfmon.maxInterval: 600
Snmpxperfmon.community: public
Snmpxperfmon.width: 300
Snmpxperfmon.height: 100

BUGS

Usually, the initial points displayed on the graphs immediately after the tool is started are skewed either too high or too low and do not represent meaningful values.  Also, the points displayed right after the polling interval is changed do not represent meaningful values.  If the agent being monitored is connected to a large number of network interfaces, the number of graphs will be large and displaying them will constitute a significant processing load on the system.  There may be cases in which changes to the display may not be clear on monochrome displays.  The use of a color display is recommended.
