# Summary

Device>Monitor>Summary

To display a summary of device performance information, select Summary from the CATEGORY popup menu, if it is not already selected.

The following information is displayed:

Switch Load % (sysTraffic)

Traffic meter value. The traffic meter value is the percentage of bandwidth utilization for the previous polling interval.

Note: This field is not supported in VS Mode.

IP Traffic (ipInReceives + ipOutRequests + ipForwDatagrams)

IP traffic pattern for the device. The value below the display represents the current traffic level. IP traffic is measured as the sum of the following MIB variables:

# ICMP

Device>Monitor>ICMP

The Internet Control Message Protocol (ICMP) is an essential part of IP. When the IP protocol runs into a problem delivering a datagram, an ICMP message is sent back to the source. The CiscoView Monitor Device window displays information about incoming and outgoing ICMP messages.

To display ICMP information for a device, from the CiscoView Monitor Device window, select ICMP from the CATEGORY popup menu.

The CiscoView Monitor device window displays the following information:

In Src Quenchs (icmpInSrcQuenchs)

Trend in the number of outgoing Source Quench messages and the latest value.

Out Src Quenchs (icmpOutSrcQuenches)

Trend in the number of incoming Source Quench messages and the latest value.

In Redirects (icmpInRedirects)

Trend in the number of ICMP Redirect Messages. A host should update its routing table based on the Redirect information.

Out Redirects (icmpOutRedirects)

Pattern in the number of Redirect Messages sent by a router. A host does not send Redirect messages.

In Echos (icmpInEchos)

Pattern in the number of incoming ICMP Echo Request messages.

Out Echos (icmpOutEchos)

Pattern and latest number of outgoing ICMP Echo Request messages.

In Echo <- (icmpInEchoReps)

Pattern and latest number of ICMP Echo Reply messages received.

Out Echo <- (icmpOutEchoReps)

Pattern and latest number of ICMP Echo Reply messages sent.

Out Addr Mask <- (icmpOutAddrMaskReps)

Pattern and latest number of incoming ICMP Address Mask Reply messages sent.

In Parm Probs (icmpInParmProbs)

Pattern and latest number of incoming ICMP Parameter Problem messages. These messages usually relate to problems in optional IP header fields.

Out Parm Probs (icmpOutParmProbs)

Pattern and latest number of incoming ICMP messages sent to report a parameter problem.

In Dest Unreachs (icmpInDestUnreachs)

Pattern and latest number of incoming ICMP Destination Unreachable Messages.

# TCP

Device>Monitor>TCP

The Transmission Control Protocol (TCP) is an essential part of IP. When the IP protocol runs into a problem delivering a datagram, an ICMP message is sent back to the source. The CiscoView Monitor Device window displays information about incoming and outgoing ICMP messages.

Two categories of TCP information are monitored in the CiscoView Monitor Device window: information about connection statistics and information about traffic. Connection statistics count the outgoing and incoming connection attempts. TCP traffic counts indicate the network health of the host. For example, a large number of retransmissions indicates a problem.

To display TCP information for a device, from the CiscoView Monitor Device window, select TCP from the CATEGORY popup menu.

The CiscoView Monitor device window displays the following information:

Active Opens (tcpActiveOpens)

Pattern and latest number of outgoing connection requests from this system.

Passive Opens (tcpPassiveOpens)

Pattern and latest number of incoming connection requests from this system. The latest number is the number of connections that occurred during the last polling interval.

Attempt Fails (tcpAttemptFails)

Number of incoming and outgoing connection requests.

Estab Resets (tcpEstabResets)

Number of times the TCP connections have changed from the ESTABLISHED or CLOSE-WAIT state to the CLOSED state.

Curr Estab (tcpCurrEstab)

Pattern for and latest number of TCP connections that are in either ESTABLISHED or CLOSE-WAIT state.

Out Rsts (tcpOutRsts)

Pattern for and number of TCP segments with the reset flag (RST) set to 1.

Click Grapher to launch your network manager's graphing application (if appropriate).

To specify the refresh rate for this dialog box, select a value from the drop-down box. Click Start/Stop to begin/end device monitoring. Click Cancel to close the dialog box. Click Print to print the contents of the dialog box. Click Help to access online help.

# SNMP Traffic

Device>Monitor>SNMP Traffic

CiscoView allows you to monitor SNMP traffic activity. The overall traffic and each of the SNMP message types (get-request, get-next-request, set-request, get-response, and trap) are monitored.

Monitoring this activity can help you determine the SNMP performance of your management station, for example, if too many MIB variables are being requested.

To display SNMP information for a device, from the CiscoView Monitor Device window, select SNMP Traffic from the CATEGORY popup menu.

The following information is displayed:

In Req Vars (snmpInTotalReqVars)

Pattern for and latest total of local MIB objects that have been retrieved successfully as a result of incoming get-request and get-next-request messages.

In Set Vars (snmpInTotalSetVars)

Pattern and latest total of local MIB objects that have been updated successfully as a result of incoming set-requests.

In Get Reqs (snmpInGetRequests)

Pattern and current number of incoming get-request messages that have been accepted and processed.

Out Get Reqs (snmpOutGetRequests)

Pattern and current number of outgoing get-request messages generated.

In Get Nexts (snmpInGetNexts)

Pattern and current number of incoming get-next-request messages that have been accepted and processed.

Out Get Nexts (snmpOutGetNexts)

Pattern and current number of outgoing get-next requests generated.

In Set Reqs (snmpInSetRequests)

Pattern and current number of incoming set-request messages generated.

Out Set Reqs (snmpOutSetRequests)

Pattern and current number of outgoing set-request messages generated.

In Get Reps (snmpInGetResponses)

Pattern and current number of incoming get-response messages accepted and processed.

Out Get Reps (snmpOutGetResponses)

Pattern and current number of outgoing get-responses generated.

In Traps (snmpInTraps)

Pattern and current number of incoming traps accepted and processed.

Out Traps (snmpOutTraps)

Pattern and current number of outgoing traps generated.
