Background Instana is the fully-automated Application Performance Management (APM) solution designed specifically for the challenges of managing microservices and cloud-native applications. It supports self-hosted installation which can be deployed on Kubernetes. In this post, I will...
This is a tutorial for how to install and run Instana on KIND Cluster. Prerequisites Two Ubuntu VMs with 16 Core, 64G Memory and 250G Disk VM should have network access to the internet One VM for Instana DB and another VM for Instana runnin on KIND The version for different...
Previously we looked at what metrics and statistics make up memory measurements and the importance of each. This understanding was critical to properly analyzing the real world examples shown. But how should this knowledge be applied toward our end goal? Ultimately everyone always asks: how...
Previously we detailed what memory statistics you can view in a Kubernetes, along with the importance of each metric. Of particular note is the (file) cache, using “available” memory to optimize IO. To demonstrate these container memory metric interactions, lets take a look at a Kafka broker...
Previously we looked at memory usage by the system as a whole, focusing on the buffers and cache usage that can grow and shrink as needed to optimize file IO. But how much cache do we really need? And how can we tell who is using it? For this deeper dive we’re going to focus on the usage...
Memory Measurements Complexities and Considerations Part 1: Buffers and (File Page) Cache System caches use all available memory to optimize disk IO. Knowing which memory metrics count this usage in their stat is therefore crucial to proper memory analysis. ...
