Meeting ID: 876 0225 4357

If joining a meeting from a Windows PC, the Zoom client will automagically download and attempt to install. For those using Linux, you can download the free (not Free) Zoom client from this page. It’s available for a variety of distributions.

For those attending in person, we will most likely adjourn to Milano’s afterward for food and socializing.

Presentations/Topics:

Munin is a networked resource monitoring tool that can help analyze resource trends and “what just happened to kill our performance?” problems.

JMB has used Munin successfully for several years to track various systems’ parameters over a period of time. In this presentation, he will demonstrate the use (and possibly an installation) of Munin and what it can display.

As always, we’ll also have discussion time for Linux and Open Source news, projects you’re working on, and questions for the rest of the group.

We don’t have any specific topic for this month, so let’s just have an open discussion time.

If you have ideas for future programs or activities, we’ll have time to talk about those as well.
