In the following example-driven tutorial we will learn how to use Prometheus metrics / OpenMetrics to instrument your code whether you are using Golang, Java, Python or Javascript. We will cover the different metric types and provide readily executable code snippets. Prometheus is an open source time series database for monitoring that was originally developed at SoundCloud before being released as an open source project.
The rest of the city may still have been in a post-Oscars haze, but over 350 monitoring mavens gathered in downtown L.A. bright and early on Feb. 25 to kick off GrafanaCon 2019. The next two days were filled with 40+ talks, including Grafana end user stories from companies like Bloomberg and Tinder.
Amazon DynamoDB is a key-value and document database that allows you to easily scale to huge numbers of records with single digit millisecond performance. However, since it’s a managed service, you have less visibility with traditional monitoring tools. As such, it becomes even more important to take advantage of the available monitoring tools in AWS. In this post, we’ll explain how to use CloudWatch to monitor DynamoDB and what is important to watch.
Recently, a new Kubernetes related vulnerability was announced that affected the kube-apiserver. This was a denial of service vulnerability where authorized users with write permissions could overload the API server as it is handling requests. The issue is categorized as a medium severity (CVSS score of 6.5) and can be resolved by upgrading the kube-apiserver to v1.11.8, v1.12.6, or v1.13.4.
This release provides fixes for the InfluxDB and Elasticsearch metric writers. If you’re using TLS connections, the latter were not closed correctly. In addition to these fixes, we’ve also backported fixes for delayed and one-time notifications. Special thanks to mdetrano for being patient and testing this one.
