I started to explore multicast network technology and talk about it from previous post. Mostly working with WowzaStreamingEngine, I wish to show principles and milestones configuration there.
We’re familiar with ABR stream playback, where we pick between multiple video bitrates. But what about streams with different audio tracks and different video pictures? Sometimes channel can be switched to different languages or different comments.
Sometimes NVIDIA users faced with driver problem trying to successfully setup Linux on workstations. Linux kernel includes open source driver, but sometimes it isn’t fully eligible for videocards. The old ones in particular. Some days ago I felt the same thing trying to step up to Fedora 24 & 4.6 kernel. I guess it could happen with any rpm-based distro like CentOS, ROSA etc..
There is a myriad of webpages about this question. But here is just my way of look at it. Multicast customization is not too tricky, but I’d like to explain how and why it works.
Many people think that the problem of application performance, security and networking lies in supported services. Like Nginx is proxying too slow or remote DBMS cannot see my network. Frequently the problem in OS. Default values of system settings can restrict our environment to make the service jobs quick and simple. The best way to change your system configuration – change the system variables.
With contemporary monitoring systems you can monitor whatever you wish. All you need – understand technology of data gathering and visualizing. 2016 year serves thousands of ways to perform it. At this post I’ll show up one of the most popular ways to do it – monitoring customization with Zabbix.
