However, a period of several hours in which there was a total packet loss can be noticed. As it can be seen, there is hardly any packet loss usually, nor is there a repetitive trend. In the following graph we analyze the packet loss of a Wifi Access point from our office. When deploying packet loss monitoring you will see in Pandora FMS console a single module with the information the plugin has been collecting, seeing whether there are times of the day when these packet losses take place repeatedly. The operation consists of sending a network check (ping) to a remote computer, which can be an IP address, a host name or a website, and checking whether there is any packet loss in the information sent. With Pandora FMS and the help of the plugin packet_loss.sh you can get all the information to find out the necessary information and be able to monitor packet loss. If you are experiencing any of these problems you must identify the cause, starting with packet loss monitoring. Software that makes network devices work properly can present certain errors or bugs.Īs in all software development, it is common for updates to appear to solve possible problems that may exist, so it is advisable to keep the software of your devices updated in order to avoid possible bugs that generate an incorrect operation of the features of your machines. These types of wireless communications are affected by often uncontrollable elements, such as interference or “noise” in the wireless network, proximity to other wireless devices, distance, physical elements (walls), etc. It is normal for Wi-Fi networks to suffer, in a timely manner, packet loss. The difference with bottlenecks is that it does not imply a single bottleneck, but it can be a general problem. If one of these points is under full capacity, there will be a waiting queue in which the information will go through more slowly, becoming discarded after a certain time. Information travels across multiple devices and links. If one of the points traffic goes through, for example a switch, does not have the capacity to correctly assume and manage the volume of traffic it receives, an accumulation will occur at this point, producing the so-called “bottlenecks”. However, monitoring reports inform you that one of the devices is at 100% capacity for extended periods. Imagine that you hired more speed, increasing it from 1GB to 10GB. It is very common for you to have enough browsing speed and for the volume of data you transfer to be acceptable, but for there to be limitations at hardware level. Overloaded hardware capacity (bottlenecks) Problems such as damaged network cards, damaged wired ports or connections, router failures or poor wired installation in your area or building may be responsible for the loss. If there is a physical problem with the hardware that deals with this network traffic it is very possible that you will experience packet loss. Some common causes of packet loss are those discussed below. We explain everything about how to monitor for free your own: The web pages you access might not show all the elements, broken images would appear or even the web format could be totally out of place.ĭo you want to be the one who controls your network and not the other way around? For security reasons, in many places the connection will be shutdown if a certain time goes by and it was not completed successfully. close your connections by leaving the channel open for too long without a clean communication. The remote servers that you are trying to access, such as web pages, file downloads, online videos, etc. Another very visible effect is that you might not be able to send emails, especially if they have attachments or they are very big. It may get to the point that a website never finishes loading and is interrupted, or a file download does not finish. It is possible that, due to slowness, loads will be completely interrupted. If you’re browsing the Internet, you could notice an excessive loading time when accessing web pages or especially, when watching online multimedia content (social media, YouTube, live streaming…). Particularly visible in video games, we could be making decisions based on outdated information, with several seconds of delay, getting to the point of performing incoherent or even harmful actions. All of them can be very annoying, the ones we present here are some of the most frequent. There are many problems arising from packet loss. These pieces, these packets, contain the information necessary for the recipient to be able to sort and use that information.Īfter being aware of this, we can already understand that when we refer to packet loss we mean that one or more pieces of information have not reached their destination in the way it was expected. Information transmitted through networks circulates in the form of pieces of information.
