Nightwatch Bandwidth Monitoring is done by measuring the network traffic on a systems network interfaces and comparing
that traffic (measured in bits per second) to the interface's maximum speed. Information for the systems network interfaces
is retrieved with SNMP.
Setup variables for bandwidth monitor
System Name
Enter or select the name or IP address
of the system on which bandwidth monitoring will be executed. Click the ... button
to select from a list of known SNMP systems on your network.
Community
Enter the community
name to use on the SNMP queries.
Scan Button
One the system name and community have
been entered, click the Scan Button to read the target system's network interfaces. These interfaces will be listed in
the Interface list box. Click on an Interface to display It's detailed information and monitoring status.
Type
This is an interface type description as retrieved from the interface.
MTU
This is the
media size or maximum packet size set for the interface.
Speed
This is the speed of the
interface in bits per second.
Phy Addr
This is the physical hardware address of the interface. Only interfaces
with a physical address can be monitored.
Status
This is the current operational status of the
interface and will be UP or DOWN.
Monitor this Interface
Select this box to enable monitoring of the selected interface.
Alarm on Errors/Discards
Generate an alarm if the number of errors or discards on an interface changes from one scan
to the next.
Input Threshold
This is the input bandwidth alarm threshold for the interface.
It can be a specific bits per second value or it can be a percent of the interface speed. Enter a number for specific bits
per second or enter a number followed by a % sign for a percent of interface speed.
Output Threshold
This
is the output bandwidth alarm threshold for the interface. It can be a specific bits per second value or it can be a percent
of the interface speed. Enter a number for specific bits per second or enter a number followed by a % sign for a percent of
interface speed.
Aggregate Threshold
This is the combined (input+output) bandwidth alarm
threshold for the interface. It can be a specific bits per second value or it can be a percent of the interface speed. Enter
a number for specific bits per second or enter a number followed by a % sign for a percent of interface speed.
