On Thursday, February 23rd, I will present at the WirelessLAN Professional Conference on how to Turn your Odroids or Raspberry Pis into Remote WiFi Monitoring Sensors. This is part of the WLPC TEN talk series, in which presenters have ten minutes for their talks. It takes less than ten minutes for me to set up and connect an Odroid or a Raspberry Pi to the NetBeez dashboard, and this post will help all you WLPC attendees follow along more easily. [···]
What differentiates good Internet Service Providers (ISP) from bad ones? Whether or not they meet their service level agreements (SLA). An SLA is a contract between a service provider and a subscriber that defines what level of performance is expected from the service provider. An ISP that doesn’t respect their SLA will deal with angry customers, have subscribers switch to other competitors, or, worse, deal with lawsuits. [···]
The WirelessLAN Professional Conference is taking place from February 21st to 23rd in Phoenix, AZ. This event brings together WiFi professionals so that they can get to know each other, and, more importantly, to learn from each other. This is reflected by the format of the conference. There are no vendor booths and all speakers take time from their busy schedules to put together presentations on a wide variety of topics. [···]
Virtual Private Networks are encrypted and authenticated connections established between two hosts across an insecure and public network, namely the Internet. These connections enable remote workers and frequent travelers to access private and internal company resources from an external location such as a home environment, or coffee shop. In this scenario, one end of the tunnel is the user’s computer running a VPN client, while on the other end there’s a VPN server (or VPN concentrator) located at a corporate site.
Ookla SpeedTest and Iperf are two very useful utilities for testing your pipes in terms of how much bandwidth they can pass. Their feature lists overlap, but there are also some differences. You are can read this post for a complete rundown on them, but in a nutshell:
SpeedTest: pushes traffic to an Internet server and measures latency, and upload and download speed.
Iperf: pushes TCP or UDP traffic between two hosts under your management and can measure bandwidth, jitter, and packet loss. Mostly used in WAN testing.
Through my discussions with fellow network engineers, I have learned that SpeedTest and Iperf are used in two main cases: [···]
The public dashboard, or more formally, the Network Status Dashboard, is one of the features we rolled out with our most recent release. This dashboard, which you can easily deploy on a web host or intranet alongside your NetBeez installation, gives you a way to share network status data with colleagues, your customers, or even the public. We think this will be a handy addition to the overall NetBeez monitoring solution.
2016 was another good year for NetBeez. If you regularly follow our blog, you are familiar with the company announcements as well as new features and functionalities that were introduced.
As you may or may not already know, we have recently released our NetBeez RESTful API. This initial version of the API provides read-only access to all the data which are accessible through NetBeez dashboard visualizations. From agents’ statuses and targets’ statuses to test statistics and alerts.
I’m taking this opportunity to go through some of the endpoints which provide the data you see on the dashboard. You can then put your creativity and interoperability skills to work and either create your own dashboards that server your very specific needs, or you can integrate your Beez data with your goto tools.
This week we’ve pushed a new software release of the BeezKeeper, which introduces two major features our users have long awaited:
- The NetBeez API: a way for users to create their own dashboard or integrations
- The NetBeez public dashboard: a status page that can be hosted on a public intranet or Internet site that shows information about the network locations and applications monitored by the sensors.
Wireless networks are dynamic by nature. A few people between you and your access point (AP) may cause signal degradation, which you may or may not notice depending on what you are doing on your device. A more common issue I’ve encountered a lot at crowded places (coffee shops, big auditoriums, concert halls) is the complete inability to connect to the network, despite having had no issues connecting during previous visits. This causes even more frustration because I expect the WiFi to be working since it worked before. [···]
