Of course, these are theoretical calculations, and you should not expect your internet to always (or ever) achieve these maximums. Cable internet can run as fast as 50 Mbps, while fiber optic speeds take the cake, clocking in at up to 1,000 Mbps. Digital Subscriber Line (DSL) internet relies on telephone lines and offers lower bandwidth capabilities, ranging from around 1.5 Mbps to 15 Mbps. If you’ve ever attempted to use the internet in a public space, like a coffee shop or library, then you know the connection is generally slower during peak usage time, when many users are trying to get online.īandwidth capacity is typically determined by the connection type. If there are too many users performing high-data activities, like watching videos or downloading files, your network speed will lag. But with too many vehicles and too few lanes, everything moves more slowly. With enough lanes and a reasonable number of cars on the road, traffic can move quickly. To understand how this all works, it helps to imagine the network as a highway, and bandwidth as the number of the lanes. A network with greater bandwidth also allows more devices to connect at once. Higher bandwidth allows data to be transferred at a faster rate (although the term “bandwidth” itself is not a synonym for internet speed). What is bandwidth usage?īandwidth refers to a network’s capacity to transfer data between devices or the internet within a particular span of time. Doing so helps managed services providers (MSPs) tailor effective solutions for those enterprises that still struggle with low bandwidth. To make insufficient bandwidth a thing of the past, companies should invest in proven bandwidth usage monitoring tools that provide both a granular and a big-picture view of enterprise data usage. This trap is sent when the aggregate bandwidth usage of the system returns to normal.However, plenty of businesses are still plagued by poor network configurations that lead to bottlenecks and slowdowns, which in turn impact worker productivity and cut into profits. To receive this trap, enable the following SNMP alarm: INTERFACE-BW-USAGE Varbinds sent in the trap message: alarmHighThreshold, alarmCurrentValue, platformLicensedThroughput, sysIpAddress This trap is sent when the aggregate bandwidth usage of the system exceeds the threshold value (configured in Mbits/second) I might try again but I did configure the following traps to at least alert when the licensed limit was near and this worked quite well: However, I've tried again this morning and it now seems to be OK (after a reboot over the weekend). However, on sampling the data manually, I still got nonsensical values out from these too (e.g. recording throughput to provide a graph showing usage), I thought that it might be better than nothing as we could reset counters at the start of the working day to at least get an impression of the figures. Although those counters don't really give what I need (i.e. 1 gbps) rather than throughput but I think that this is represented by the following:Īn estimate of the interface's current bandwidth in unitsĪny got any ideas? I just want to monitor the throughput of the device (in a similar fashion to the 'Throughput' figure on the 'Dashboard'. Now, to me that looks like a figure which shows the speed rating of the interface (i.e. across different VPXs in different locations) I always get the following result even though one of the NetScalers is a test device with only 5 mbps licence: However, no matter when or where I query the value (i.e. I'm setting up monitoring of some NetScaler VPXs and wish to capture the throughput for various network interfaces (I've managed to set up CPU and memory usage successfully).Īnd added the unique identifier for the interface (e.g.
