How to Monitor CPU and Memory on Ubiquiti Unifi Devices

Retune AB manages a variety of Ubiquiti devices -- wireless data communication products for enterprise and wireless broadband providers. Naturally, we wanted to bring these in under monitoring.

Why Shift-Right is Essential for SaaS Applications

Windows as a Service: Stay Ahead. Keep Control.

With technology’s unrelenting advance, the evolution of the digital workplace has unarguably entered the fast lane. Microsoft – which provides critical digital workplace solutions through their Windows OS – is no exception. Indeed, end users indispensably depend on Microsoft’s range of workplace services to achieve everyday tasks – from simple log-ins to advanced programming – putting them at the front lines of any new updates and modifications.

On the merits of pubsub & workflows (or, why Sensu over Nagios)

Not too long ago in the Sensu Community Slack, the question: “Why Sensu instead of Nagios?” arose. Specifically, “How do I convince my boss to choose Sensu over Nagios?” I responded to the thread, but decided it was worthwhile to share my response with the wider community. At Willis Towers Watson, we moved from Nagios to Sensu 1.2 almost a year ago (and now we’re upgrading to Sensu Go).
