Use this dialog to configure a Network Statistics Active Monitor Threshold. This monitor uses SNMP to query a device to determine the rate-of-change for an OID, or the difference between the current poll value and the last poll value for an OID. With the exception of the tcpCurrEstab threshold, all of the thresholds used in the Network Statistics Monitor are rate-of-change monitors.
There are three types of thresholds you can configure:
When configuring a threshold, it is helpful to copy the OID from the parameter description listed on this dialog after you select a parameter. Paste this OID into the Object ID box on the SNMP MIB Walker (Tools > SNMP MIB Walker), then click Walk. After the walk scan is complete, note the value listed. Perform several more walk scans, noting the value after each scan completes. These values illustrate how much this particular value may change over the course of several queries. Use these values as guidelines when configuring a threshold for the Network Statistics Monitor.
Note: You can only configure one threshold at a time
Received datagrams cannot exceed___. Enter a numerical value for the threshold. If the number of received datagrams is greater than this number, the monitor alerts you.
Received datagrams cannot exceed___. Enter a numerical value for the threshold. If the number of received datagram errors is greater than this number, the monitor alerts you.
Received datagrams cannot exceed___. Enter a numerical value for the threshold. If the number of discarded received datagrams is greater than this number, the monitor alerts you.
Datagrams delivered cannot exceed___. Enter a numerical value for the threshold. If the number of delivered datagrams greater than this number, the monitor alerts you.
Datagram requests cannot exceed___. Enter a numerical value for the threshold. If the number of datagram requests is greater than this number, the monitor alerts you.
Transmits discarded cannot exceed___. Enter a numerical value for the threshold. If the the number of transmits discarded is greater than this number, the monitor alerts you.
Attempt connection failures cannot exceed___. Enter a numerical value for the threshold. If the number of attempted connection failures is greater than this number, the monitor alerts you.
Established connections cannot exceed___. Enter a numerical value for the threshold. If the number of established connections is greater than this number, the monitor alerts you.
Received segments cannot exceed___. Enter a numerical value for the threshold. If the number of received segments is greater than this number, the monitor alerts you.
Transmitted segments cannot exceed___. Enter a numerical value for the threshold. If the number of transmitted segments is greater than this number, the monitor alerts you.
Datagram deliveries cannot exceed___. Enter a numerical value for the threshold. If the number of delivered datagrams is greater than this number, the monitor alerts you.
Application port errors cannot exceed___. Enter a numerical value for the threshold. If the number of application port errors is greater than this number, the monitor alerts you.
Received errors cannot exceed___. Enter a numerical value for the threshold. If the number of UDP errors is greater than this number, the monitor alerts you.
Transmitted datagrams cannot exceed. Enter a numerical value for the threshold. If the number of transmitted datagrams is greater than this number, the monitor alerts you.
