Bandwidth Monitor utility of OpUtils software provides a graphical view of real time traffic in a device. The Bandwidth Tool is ideal for identifying bottlenecks related to bandwidth within the network. You can monitor the network traffic utilization/ bandwidth usage both at the interface level and at the device level.
Click the Add Devices link
Specify the Device IP Address/Name and its SNMP community in the respective fields and click Get Interfaces.
This will list all the available interfaces of the device along with its status and speed. The auto-detected SNMP version is also shown. You also have an option to choose an interval to monitor the interface, the default being 1 year. Select the interfaces to be monitored and click Add Interface.
The selected interface gets added for monitoring network traffic.
Repeat steps 2 & 3 for adding more interfaces.
Note: Bandwidth Monitoring of all the interfaces will happen at an pre-defined interval of 5 minutes. The In and Out bandwidth utilization values in the summary view will appear in the next polling cycle, i.e., after 5 minutes, which will be the cumulative bandwidth utilization value in the past 5 minutes.
Summary ViewThe Summary View provides the details of the monitored interfaces along with their status, speed, and current in/out network bandwidth utilization details.
Clicking the interface link (ifName) will show the graphical representation of network bandwidth utilization for the last one hour, last one day, last one month, and last one year. A link to view the tabular data is also provided below each graphs.
To modify the Monitor Until period, click the Modify link corresponding to that interface and select a different period. Monitoring will continue till the selected period from the time of modification.
To delete an interface from being monitored, click Delete link corresponding to that interface.
Detailed ViewTo view the detailed network traffic for an interface:
Select the Volume, Speed, Utilization, and Packets tab to view the corresponding information. The details provides both the graphical and tabular data of the selected parameter for the last one hour, last one day, last one month, and last one year. You can choose the period from the combo box.
- Click a interface link from the Summary View.
- Select the Detail Traffic tab to view its complete details
Device-level ComparisonDevice-level network traffic comparison provides a graphical representation of the each of the interfaces of the selected device in a multi-line graph. This gives an immediate picture of the most bandwidth consuming interface of a device in the network. The comparison is provided for the following periods, each in separate tabs:
- Current - Comparison based on the current network traffic utilization values
- Daily Traffic - Based on the last one day network traffic utilization
- Monthly - Based on the last one month network traffic utilization
- Yearly - Based on the last one year network traffic utilization
The Bandwidth Monitor tool measures and generates alerts whenever the network bandwidth utilization criteria is exceeded. The Bandwidth Monitor tool can be configured to notify these alerts through email or by playing a sound. Given below are the steps to configure:
Click the Configure Alert link available in the Bandwidth Monitor tool.
Select the device for which you wish to configure alerts. To configure alerts for all the devices, select All from the list.
Specify the Alert Criteria. Alerts will be generated by the Bandwidth Monitor tool based on the defined criteria.
To be notified by email, select the Enable Email Alert check box and specify the recipient email addresses as comma separated. You can have different email recipients for different devices.
Note: To enable email notifications, you should configure the SMTP properties. Refer to Configuring SNMP Properties topic for details.
To enable sound alerts, select the Enable Sound Alerts check box available under Global Sound Alert Configuration, select the sound to be played for different severity levels, and Save. It may be noted that the sound alert configuration applies commonly for all the devices added in the Bandwidth Monitor tool and not device-specific. To play the selected sound, click the icon.
Alert Cleanup Policy: Specify the maximum number of Alerts to be stored in the database, the default being 2000. When you delete the older alerts, you have an option to save them as a csv file for future reference.
The Network Bandwidth Utilization Reports can be exported to PDF, XLS and CSV formats. To export the data, click the Export link from the top-right and select a format to export. This will export the data that is currently being viewed in the Bandwidth Monitor tool. The network traffic usage details from the Summary view, the details view, and the comparison view can be exported to the desired formats.
