http://fractio.nl/2014/10/03/why-do-you-want-to-lead-people

Why do you want to lead people? Understanding your motivations for a career change into management is vitally important to understanding what kind of manager you want to be. When I made the transition into management, I didn’t have a clear idea of what my motivations were. I had vague feelings of wanting to explore the challenges of managing people. I also wanted to test myself and see if I could do as good a job as role models throughout my career. It is undeniable that there is a pay bump when moving t...

Data driven alerting with Flapjack Puppet Hiera. On Monday I gave a talk at Puppet Camp Sydney 2014. About managing Flapjack data (specifically: contacts, notification rules) with Puppet Hiera. There was a live demo of some new Puppet types I’ve written to manage the data within Flapjack. This is incredibly useful if you want to configure how your on-call are notified from within Puppet. The code is a little rough around the edges, but you can try it out at in the. He is the creator of Visage.

It's not a promotion - it's a career change. The biggest misconception engineers have when thinking about moving into management is they think it’s a promotion. Management is not a promotion. It is a career change. If you want to do your leadership job effectively, you will be exercising a vastly different set of skills on a daily basis to what you are exercising as an engineer. Skills you likely haven’t developed and are unaware of. You exist to listen to people (not just hear them! There are two main c...

Applying cardiac alarm management techniques to your on-call. If alarms are more often false than true, a culture emerges on the unit in that staff may delay response to alarms, especially when staff are engaged in other patient care activities, and more important critical alarms may be missed. In an on-call scenario, I posit two main factors contribute to alert fatigue:. The accuracy of the alert. The volume of alerts received by the operator. Alert fatigue can manifest itself in many ways:. When rollin...

Flapjack, heartbeating, and one off events | Fractional by Lindsay Holmwood

http://fractio.nl/2014/05/09/flapjack-heartbeating

Flapjack, heartbeating, and one off events. Flapjack assumes a constant stream of events from upstream event producers, and this is fundamental to Flapjack’s design. Flapjack asks a fundamentally different question to other notification and alerting systems: How long has a check been failing for? Flapjack cares about the elapsed time, not the number of observed failures. Take this scenario with a LAMP stack running in a large cluster:. Gives us a lot of practical tools for modelling scenarios like these,...
