You see a 4x change in ram across those devices.
The process closely follows that of a previous note. The same Prometheus binary you can run on a Pi scales to millions of series and millions of samples per. This results in less code and better performance.įrom my perspective, there are a few pain points: The codebase of ns-3 is well-designed from a C++ programming perspective.īetter yet, ns-3 introduced a pattern named direct code execution (DCE), which reuses the existing linux network stack to perform simulation. However, a 2016 paper demonstrated that ns-3 won by a slight margin. For example, ```prometheus_http_request_total" | base64 -decode echoĪ strong contender of ns-3 is the celebrated OMNET++.
The **label** is used to identify different dimensions of the same time series. For instance, the ```http_requests_total``` metric aggregate the total number of HTTP requests received. of a network device, designed to filter packets sent to that network device. The **metric name** specifies the feature of a system that is measured. /rebates/&252fprometheus-64bit-devices. A story about understanding how eBF and Prometheus can play together to. Each value consists of three parts: metric, value and timestamp (in ms). Specifically, Prometheus stores value that belong to the same metric by time series. TSDB is a database optimized for handling time series data. Prometheus consists of a **TSDB** (time series database).
