SSH is nearly ubiquitous in today’s enterprises, and is the predominant tool for managing unix and linux servers, and the applications and data that they host. Poor practices around the deployment and management of the SSH infrastructure could easily leave your enterprise vulnerable to a breach. Are you in control? SSH, Secure Shell protocol, is now nineteen years old and broadly deployed across...

In this online article Dr. Gunther digs down into the UNIX kernel to find out how load averages (the “LA Triplets”) are calculated and how appropriate they are as capacity planning metrics.

This is the second in a two part-series where we explore the use of UNIX load averages in performance analysis and capacity planning.

This is an unexpected Part 3 to the discussion about the UNIX load average metric answering the question of where the weight factor comes from.

This article is about delusions that arise from incorrect interpretation of load test measurements.

This paper discusses avoiding calculation results that are more precise than is justified by precision of corresponding measurement input data.

This is the final online article concerning the concept of application scalability. Here, you will learn how to determine value of the parameters that control scalability.

This is a little quiz to test your understanding of the triplet of numbers that appear in the UNIX® load average (LA) performance metric.
