How to simplify SNMP implementation

The following is a guest post from Jean Tunis, the principal consultant and founder of RootPerformance. You want implementations to be simple. Who doesn’t? But often, that’s not the case. SNMP is one of the oldest used protocols to manage a network. SNMP stands for simple network management protocol, but it might not have been all that simple for you. Maybe it was simple back in the late 1980s, when SNMP became a standard protocol for network monitoring.

TLS monitoring

Uh oh, the site’s certificate has expired. How do we generate a new one? Where’s the private key? Which servers need the new cert? What even goes in the cert? If this sounds all too familiar, rest assured you’re not alone. Outages due to expired certs are far too common and it happens to sites of all sizes (one recent example includes Microsoft Teams going down for several hours due to an expired cert). Disruptions like this are entirely preventable with proper monitoring in place.

Monitoring event pipelines: Why you need one, and why you should stop rolling your own

Over the last 10 years, the landscape that we manage, maintain, and control as operators and developers has changed dramatically. We’ve shifted from monolith to microservices, from bare metal to VMs to containers to function-based computing — and it’s changed how we need to approach monitoring and observability.

The best DevOps tools (according to the folks building Sensu)

Because Sensu is a tool made for (and by!) operators, I wanted to share our own favorite tools in the DevOps ecosystem (aside from Sensu, of course!). I surveyed the fine folks who work at Sensu on what their favorite DevOps tools are, and why. And while we don’t always agree on a specific tool (everyone has their own favorite text editor), it’s safe to say that open source is a constant theme. Read on to learn about our tools of choice for editors, programming, storage, IaC, and more.

Chaos engineering + monitoring, part 2: for starters

Oh man, did I get ahead of myself in my last post! I started chatting tools, and I realize now that I really should have been talking more about why I’m using Sensu and Gremlin. But it didn’t occur to me until last year at Monitorama. John Allspaw gave the keynote talk (Taking Human Performance Seriously). While you can watch the talk here, I’ll highlight a few points...
