Our company is using Icinga for quite some time now to monitor our whole infrastructure and its customers infrastructure. We deploy many Icinga instances for different teams and customers (see this video for more information). To manage the configuration of these instances, we use the Icinga Director module. This gives us an easy way to deploy checks, services and hosts in Icinga. The teams do not have access to the configuration files of Icinga, so every change is done via the Director frontend.

What is bandwidth? Bandwidth refers to the amount of data that can be sent or received by a particular device in a stipulated period. This is measured in Mbps (Megabits per second). Very often, people use bandwidth to refer to the speed of the internet connection. However, that is not the case. Talking about bandwidth vs. speed, the former helps understand the quantity of data transferred per second. At the same time, the latter focuses on the rate of data transfer from the source to the destination.

Ubuntu and Launchpad use OpenPGP keys heavily. Each source package is signed with the uploader’s key, and binary and source package downloads from Ubuntu’s primary archives and from users’ Personal Package Archives (PPAs) are indirectly signed by the publisher process with per-archive keys of its own. Access to Launchpad’s bug-manipulation interface is also controlled by OpenPGP. As a result, Launchpad needs a reliable key-storage and synchronization mechanism.
