Prometheus does one thing and it does it well. It has a simple yet powerful data model and a query language that lets you analyse how your applications and infrastructure are performing. It does not try to solve problems outside of the metrics space, leaving those to other more appropriate ...
As for the avg_over_time function, it is usually used for gauge metrics. P.s. Prometheus may return unexpected fractional results from increase() function applied to integer counter. This is because of extrapolation - see this issue for details. If you want obtaining the exact...
To answer these questions, you need to continuously monitor elements in the system for anomalies, issues, or alerts for maintenance activities, in order to ensure that the services operate and can be consumed as per agreed performance levels. Metrics are the sources of raw measurement data that ...
Before we explore how to build infrastructure designed to run applications in the cloud, we need to understand how we got where we are. First, we’ll discuss the benefits of adopting cloud native practices. Next, we’ll look at a brief history of infrastructure and then discuss features of...
kubectl get --raw "/apis/custom.metrics.k8s.io/v1beta1" | jq . The exposed metrics that also exists in Prometheus are shown below. For example, the "application_httprequests_active" metric is exposed by our API. Also, this can be used with HPA like this. ...
Metrics collect CPU load, storage utilized, response rate, etc. These data types provide a statistical report for improving and maintaining the system and its operations. Distributed context propagation: In more complex systems, it is essential to have a comprehensive understanding of the flow of ...

However, the affectedsitemust be carefully protected to eliminate the slightest chance of infection. In some cases, there are chances of a permanent scare or hypo/hyper-pigmentat...
ManualReader is used in the test on metrics in tracing-opentelemetry 👍 1 Member jtescher commented Nov 2, 2023 ManualReader is useful for creating exporters that have to be manually queried (pull vs push). Prometheus would be a good example if that, can see the impl in this file fo...
Gatling and Locust are two popular open source load testing solutions. In this post we compare them according to multiple capabilities, like protocol support, script execution capabilities, and monitoring.
