Trend Overview

Scrutinizer determines the total utilization on a link by compiling all NetFlow data received pertaining to all interfaces. In Bound and Out Bound are both compiled. NOTE: Because Scrutinizer does not use SNMP to poll in and out octets to gain knowledge of overall utilization the following must be considered.

NetFlow should be turned on all necessary interfaces in order for Scrutinizer to accurately represent Out Bound traffic per interface.
Overall utilization on the interface could be under stated if the hardware can't keep up with sending the NetFlow packets. A router or switch could drop NetFlows before they even leave the device. To check to see if this is the problem, login to the Cisco device and type in the following:
router-name>sh ip flow export
At the bottom of the export, look for something like:
"294503 export packets were dropped due to IPC rate limiting".
If this counter is incrementing, the hardware cannot keep up with the export demands.

Navigation Options

There are a several navigation options using the data displayed in this screen:

Click this icon to trend the data in percent utilization. Scrutinizer must know speed of the interface to calculate this. Click on the SNMP icon to configure the interface speed manually.
Click this icon to trend the data in bits per second in lieu of percent utilization.
Click this icon to launch a real time trend in a pop up window that tells Scrutinizer to start SNMP polling the interface and relay the actual bits/sec to the popup window (e.g. see below):

IMPORTANT: for Real Time to work, a valid SNMP community string must be specified for the router under Manage Devices
