BASE: Getting Started with Arduino

by Steve Stegmann and Chuck Doolittle

We briefly discuss the major differences between Arduino and a Raspberry Pi. Then we select a simple project and document the building and operation of it. We also document a simple getting started kit we purchased. We will have the completed project with us at the presentation.

This session might show factors common with both personal and enterprise computing.

MAIN: How to Configure syslog-ng for High Performance

by Mo Hassan of Splunk

Tips and tricks to get more events per second (EPS) from your syslog-ng. I will be discussing how I built syslog-ng environment that handled 30k-40k eps front-ending large Splunk installation.

From Wikipedia:

syslog-ng is a free and open-source implementation of the syslog protocol for Unix and Unix-like systems. It extends the original syslogd model with content-based filtering, rich filtering capabilities, flexible configuration options and adds important features to syslog, like using TCP for transport. As of today syslog-ng is developed by Balabit IT Security Ltd. It has two editions with a common codebase. The first is called syslog-ng Open Source Edition (OSE) with the license LGPL. The second is called Premium Edition (PE) and has additional plugins (modules) under a proprietary license.

syslog-ng uses the standard BSD syslog protocol, specified in RFC 3164. As the text of RFC 3164 is an informational description and not a standard, some incompatible extensions of it emerged. Since version 3.0 syslog-ng also supports the syslog protocol specified in RFC 5424. syslog-ng interoperates with a variety of devices, and the format of relayed messages can be customized.

Mo presented to the SLUUG general mtng in Feb 2017..

>>TOPIC Comparing Docker Containers in Linux vs MacOS
>>Mo used Docker to make containers for specific apps and implemented them in both MacOS and in Linux. He found the effort significantly different. Stricter POSIX compliance in MacOS BASH?

Mo Hassan is a field engineer/tech rep for the company's ~"SQL" inquiry language. (Not open src but free for individual, non-commercial user.)

This should be an excellent talk, both for those working on large, busy systems or on smaller, more personal systems who's syslog is recording LOTS of detail.

Monthly Meetings

We start the general meeting at 6:30 PM with our BASE session (usually focused on personal computing); which may include either amazing graphical packages, blinking lights, command line wonders, demonstrations of useful applications, displays of newly discovered web sites, major resolution of long standing anomalies, quantum discoveries, superb tutorials, or shifts in both time and space.

Sometime after 7:00 PM we get to a quick welcome, introductions, announcements, current events of interest, and a general CALL FOR HELP (Questions and Answers) segment.

Sometime after 7:30 PM, we may take a short break before our MAIN topic (usually focused on enterprise computing),

All of our meetings are free and open to the public. There is no individual membership fee.
