In this post we will cover how to monitor the Java Runtime Environment (JRE). You will learn how to assess the performance of your Java application by profiling its memory usage, the garbage collector metrics, monitoring Java daemon and user threads and other fundamental JRE metrics. We will finish with a real Java JRE troubleshooting example using opensource Sysdig and Docker.

Today we announced the launch of enterprise-grade Prometheus monitoring with Sysdig Monitor 3.0. We’ve added new Prometheus capabilities like PromQL, a Grafana plugin and new enhancements for our already rich Kubernetes monitoring. If you love Prometheus like we do, and especially if your cloud environment is growing quickly, read on to learn more about what we’re doing with Prometheus, Kubernetes and more.

Here at Sysdig we follow Kubernetes development pretty closely. Next Tuesday the next release of our favourite orchestration tool will get out of the oven freshly baked, so this is a summary of what’s new in Kubernetes 1.12!

More groups are progressing from just talking about Event-Driven Automation to actually doing it in practice. StackStorm helps make this easy. When organizations start offloading business-critical tasks and automating for real it becomes essential to ensure that the Automation engine itself is not a single point of failure when it is responsible for recovering a fleet of servers, managing datacenters, and automating remediations.

Cloud-native development and microservices enable development teams to work more efficiently and innovate faster. Operators appreciate the container environment because it increases infrastructure utilization, enabling them to accomplish more with less while managing critical applications at unprecedented scale. Kubernetes and containers adoption growing fast in the last few years.

When there’s an incident, Grafana is often the starting point for figuring out a response. Users look at a time series panel and form a hypothesis. And in many situations, they’d like to dive deeper. To help make that easier, Grafana Labs has created the Explore UI, which allows you to iterate quickly through Prometheus queries, while leaving your dashboards intact.

We covered how to install a complete ‘Kubernetes monitoring with Prometheus’ stack in the previous chapters of this guide. But using the Prometheus Operator framework and its Custom Resource Definitions has significant advantages over manually adding metric targets and service providers, which can become cumbersome for large deployments and doesn’t fully utilize Kubernetes’ orchestrator capabilities.

Ready to deploy an AppD application agent to OpenShift? These detailed examples show you how. There are several ways to instrument an application on OpenShift with an AppDynamics application agent. The most straightforward way is to embed the agent into the main application image.
