15 APM tools compared by #Gartner. Chosen, evaluated and ranked for each capability, and scored on a five-point scale. The capabilities assessed for each use case included business analysis, service monitoring, anomaly detection, distributed profiling, application debugging, and workload planning. Which is the best for you?

There are several APM solutions in the market all grasping for a slice of the market share and claiming they’re the best tool for you. But are they?

Goran,

You're still not seeing what I see. What I see is a management problem, not a technical one.

To answer your questions, however:

A production critical system should have redundant servers behind a load balancer. If a server rolls over and dies, then the load balancer should detect the problem in anywhere from a few tens of seconds to a few minutes, and stop directing traffic to the dead server. I should get a mail message that I can deal with in the morning, but no need to be paged, the system has worked around the problem and everything is fine. It is a management decision to invest in a load balancer and invest in software that can recover a session that has migrated from one server to another.

If I am getting a DDOS attack, I'm not sure what I can do about it anyway other than add more resources until I out brute force the thing. There are services that will do that - akamai springs to mind - automatically. It is a management decision to purchase these services to protect you from a DDOS attack.



There is another way to address your concern. Suppose that management decides that this site requires human supervision 24/7. Then management should either staff it 24/7 or else contract with a service that will staff it 24/7. Again, that is a management decision. When making that decision, it is important to keep human frailties into consideration. Consider http://www.cnn.com/2011/TRAVEL/03/24/dc.air.traffic.suspension/ . The FAA just assumed that they change the guy's schedule around to meet their administrative requirements, and the human need for sleep all of a sudden became front page news.

I want you to look at our conversation and then tell me if there is anything in your responses that indicates any sort of empathy or consideration of a sysadmin as a human being.

The Linux Foundation’s New Training Bundle to Increase Career Mobility for SysAdmins

New course and certification bundle to accelerate opportunities for
advanced Linux learning among career technologists

SAN FRANCISCO, May 12, 2016 – The Linux Foundation, the nonprofit advancing professional open source management for mass collaboration, today announced the availability of its new course, LFS211 Advanced Linux System Administration and Networking. The course provides the knowledge and skills necessary to succeed as a senior Linux sysadmin, as well as to pass the Linux Foundation Certified Engineer (LFCE) exam, which comes bundled with the new course.

The 2016 Open Source Jobs Report, produced by The Linux Foundation and Dice, finds that 51 percent of hiring managers say hiring certified professionals is a priority for them, and 47 percent of open source professionals plan to take at least one certification exam this year. Certifications are increasingly becoming the best way for professionals to differentiate from other job candidates and to demonstrate their ability to perform critical technical functions.

“More individuals and more employers are seeing the tremendous value in certifications, but it can be time-consuming and cost-prohibitive to prepare for them,” said Linux Foundation General Manager for Training Clyde Seepersad. “The Linux Foundation strives to increase accessibility to quality training and certification for anyone, and offering advanced system administration training and certification that can be accessed anytime, anywhere, for a lower price than the industry standard helps to achieve that.”

With the tremendous growth in open source adoption across technology sectors, it is more important than ever for IT professionals to be proficient in Linux. With the recent embrace by Microsoft of Linux on Azure, every major cloud platform is now based on or, as is the case for Azure, runs Linux. Similarly, OpenStack - one of the leading cloud platforms, for which The Linux Foundation also offers a course to prepare for the new Certified OpenStack Administrator exam - is deployed on Linux. Sysadmins of all stripes today need to be familiar with Linux, and the type of training provided by this course confers the knowledge and skills necessary to manage these systems.

LFS211 serves as preparation for the advanced LFCE exam in the way LFS201 Essentials of System Administration serves as preparation for the Linux Foundation Certified SysAdmin (LFCS) exam. Students in the new course will have access to 40-50 hours of coursework, and over 50 hands-on labs, which includes practical experience that translates to real-world situations. Becoming LFCE certified provides individuals who are more established or advanced in their IT careers the opportunity to progress further and demonstrate their knowledge. Sysadmins who pass the LFCE exam have a wider range and greater depth of skill than the LFCS. Linux Foundation Certified Engineers are responsible for the design and implementation of system architecture and serve as subject matter experts and mentors for the next generation of system administration professionals.

Individuals interested in registering for LFS211 can do so at http://go.linuxfoundation.org/rd-lfs211-launch-pr for the introductory price of $349, including access to the course material for one year, and a voucher to take the LFCE exam up to two times. For more information on Linux Foundation training and certification programs, visit http://training.linuxfoundation.org.

Suggestions  - 
 
Which would you suggest... MySQL or MariaDB and why?
(explain below)

Reason I'm asking. I'm about to write a followup to the "My.cnf tuning – Avoid this common pitfall" article I posted last year and I would like to cover some of the differences, pros and cons between MariaDB and MySQL. Curious of the split.

MySQL was design for people with small projects and small databases. It is nearly ideal for such situations.
For large projects, databases, heavy SELECTs, complicated stored procedures - there is PostgreSQL.
Using MySQL or MariaDB in that case is possible, but painful.
Also, two MySQL forks are drifting apart as we speak.

With the Raspberry Pi 3 already being much faster than its predecessors. For a performance boost I've simply been using:

force_turbo=1
boot_delay=1

* force_turbo=1 Voids Warranty. boot_delay=1 helps to avoid sdcard corruption when force_turbo is enabled.
