Performance Metrics of Network Monitor

You can view the device performance snapshot under monitor details page. Inside the home page, click on the respective network device to access the monitor details page. Displays the system's details such as the IP address, operating system, time stamp of previous and next polls and a description on the system hardware details. System description is seen on the SNMP-enabled devices. Get to know how to add a network monitor and set thresholds and be alerted when the configured value exceeds.

Various reports can be viewed by navigating across the following tabs:

Device Performance:

Parameters Description
Response Time Shows the current response time of the device. Clicking on the chart displays the response time history
Packet Loss Shows the packet loss percentage for the device on that day
Device Details Shows general details of the device including DNS, vendor name, IP address, category of the device
Hardware Details Gives the manufacturer and model name, along with the serial number 
CPU Utilization Shows the CPU utilized by the device
Memory Utilization Shows the memory utilized by the device

Network device performance

Performance Counters:

This section lists the custom performance counters associated with the device and displays the hardware specific metrics like temperature stats, memory and CPU utilization.

Performance counters

Tabular Performance Counters:

Monitor the tabular SNMP OIDs of your network devices. With these, you can monitor multiple instances of the same attribute (such as in the memory, disk, or interfaces) in a single network device.

tabular performance counters

Router Performance:

Track and monitor the availability and response time of routers configured on your network. Get deep visibility into key performance indicators like buffer hit statistics, buffer miss statistics, CPU utilization, Memory utilization and more.

Parameters Description
Buffer Hit Statistics Shows the average of the number of buffer hits for a period of time, along with the size of the buffer. There are four types of buffers: huge, large, big, medium 
Buffer Miss Statistics Shows the average of the number of buffer misses for a period of time, along with the size of the buffer. There are four types of misses: big, small, medium, large
CPU Usage The amount of CPU utilized by the router for a period of time 
Cisco Memory Utilization Shows the memory consumption of Cisco routers for a period of time 

Interfaces:

Displays the list of interfaces in the selected device with their status and other details. Click the interface name link to view its availability and graphs on traffic and bandwidth utilization.

Toggle between the licensed interfaces that are being monitored (Active interfaces) and the unlicensed interfaces that are not being monitored (Suspended interfaces).

Parameters Description
Interface Name Name of the interface obtained from RFC-1213
Type Type of the interface like ethernet, VLAN etc
In Traffic  Amount of traffic received by the interface in bits/sec
Rx Utilized (%) Amount of received traffic utilized  by the interface in percentage
Out Traffic  Amount of traffic transmitted by the interface in bits/sec
Tx Utilized (%) Amount of transmitted traffic utilized by the interface in percentage
Errors (%) Percentage of error packets received by the interface
Discards (%) Percentage of packets discarded by the interface from the total number of packets 
Status Shows whether the interface is up, down or in the trouble state 

Network interface details

Clicking on an interface provides the following details:

Parameters Description
Admin State Tells whether the admin state of the interface is up or down
Operational State Tells whether the operational state of the interface is up, trouble or down
Receive Utilization Amount of received traffic utilized  by the interface 
Transmit Utilization Amount of transmitted traffic utilized by the interface 
Utilization Average of the received and transmitted traffic utilized
In Traffic Amount of traffic received by the interface 
Out Traffic Amount of traffic transmitted by the interface 
Traffic Average of the in traffic and out traffic
Packets Received The number of error packets received to the interface
Packets Sent The number of error packets sent by the interface
Packets The total number of packets handled by the interface
Errors (%) Percentage of error packets received by the interface in percentage 
Discards (%) Percentage of packets discarded by the interface from the total number of packets in percentage

Bandwidth details are also captured along with other metrics.

Parameters Description
Bandwidth Received (bps) The amount of bandwidth that can be received by the interface. This is a constant value from the SNMP response of that interface
Bandwidth Transmitted (bps) The amount of bandwidth transmitted by the interface. This is a constant value from the SNMP response of that interface
In Traffic (bps) Amount of traffic received by the interface  
Out Traffic (bps) Amount of traffic transmitted by the interface 
Rx Utilized Amount of received traffic utilized  by the interface 
Tx Utilized Amount of transmitted traffic utilized by the interface 
Avg Rx Packet Size (bytes) The average packet size received for a period of time
Avg Tx Packet Size (bytes) The average packet size transmitted for a period of time 
Received Packets The number of error packets received to the interface 
Transmitted Packets  The number of error packets sent by the interface
