Why should I check my bandwidth?


Looking to optimize the performance of your network? If so, sufficient bandwidth is a must.
A “bandwidth check” will immediately show you how much bandwidth is available in your network.
Such a check is especially important to rapidly growing businesses. These companies have more
and more end devices and eventually reach their capacity limits. A bandwidth check lets them
determine if it’s time to upgrade their networks. Not to mention avoid costly crashes and the
losses in sales that come with them.

Where’s all the bandwidth going?

PRTG monitors bandwidth usage directly on the router and displays all incoming and outgoing data traffic. You’ll see which applications, servers, and users are consuming the most bandwidth. You might also learn that your router is configured incorrectly.

Bandwidth usage test

statistics.png


The PRTG Bandwidth Monitoring Tool checks your bandwidth around the clock and provides detailed statistics on bandwidth consumption. Do peak loads occur at certain times? Could these loads be avoided via the efficient use of automated processes? Are unnecessary services or processes consuming unreasonable amounts of bandwidth?

PRTG displays bandwidth usage in easy-to-read lists and charts. Our Packet Sniffer and Flow sensors filter results by port number, IP address, protocol, and more.

PRTG comes with a user-defined alert function, allowing you to be informed of bandwidth bottlenecks by SMS, email, or push notification. You can therefore quickly take action and eliminate most problems before they become severe – and cost your company money.

3 situations where bandwidth checks come in handy

Scheduling backups

Most backups or database synchronization processes require lots of bandwidth. PRTG shows you the time of day when the least amount of bandwidth is consumed. By scheduling backups during low peak periods, you'll optimize your capacities and prevent important business processes from coming to a halt.

Verifying the terms of contracts

Is your ISP really providing the amount of bandwidth that was promised? PRTG will show you exactly how much bandwidth is being delivered to your network. Comprehensive statistics can help you prove that the terms of a service level agreement (SLA) are not being met.

Expanding your network

Getting ready to install new ERP software that requires 5 Mbps of bandwidth? PRTG will let you know if you have enough bandwidth to run the software on a sustained basis or if you’ll need to upgrade.

 

Sensors to help you check your bandwidth

Packet Sniffer

Monitors the headers of data packets that pass a local network using a built-in packet sniffer. It can show the following traffic types (analyzes only header traffic!):

  • Chat (IRC, AIM)
  • Citrix
  • FTP/P2P
  • Mail, WWW
  • Remote control (RDP, SSH, Telnet, VNC)

Packet Sniffer Sensor

SNMP

Uses a MIB library file to create sensors that monitor a device via SNMP and provides custom monitoring beyond the standard SNMP sensors of PRTG.
