I care a lot about instrumentation and telemetry and OpenTelemetry, so I was thinking of joining the observability engineering team at my company… but it seems like they spend all their time managing Prometheus and Grafana. I guess I was expecting something very different?

Here at Grafana Labs, we’re always looking for ways to provide our customers with a choice of platforms where they can run Grafana Enterprise Metrics (GEM). As part of that mission, we’re pleased to announce that we’ve added Red Hat OpenShift 4.x support to GEM. GEM, as you may know, is a leading enterprise metrics solution.

Datadog has made a name for itself as a popular cloud-native application performance monitoring tool, measuring a system’s health and status based on the telemetry data it generates. This telemetry includes machine-generated data, such as logs, metrics and traces. Cloud based applications and infrastructure generate millions (even billions) of logs – and analyzing them can generate a wealth of insights for DevOps, security, product teams and more.

The idea of a VLAN, or Virtual Local Area Network, is simple enough, right? It’s hard to imagine any work in a modern networking/IT space without having encountered, set up, or managed a VLAN. Well if that’s all you needed to know about VLANs, we’d be done here, but there’s a bit more to it. To cover our bases: In most modern networks the primary purpose of the LAN is to provide connectivity to a wider network, most notably the internet.

We need to remove a vmstorage node from VictoriaMetrics cluster gracefully. Every vmstorage node contains its own portion of data and removing the vmstorage node from the cluster creates gaps in the graph (because replication is out of scope).
