What is Prometheus?

Prometheus is an open-sourced software application aimed at monitoring and alerting. It is used for recording real-time numeric metrics in a time series database. It was developed by SoundCloud in 2012, while Prometheus 1.0 was released in May 2016 and Prometheus 2.0 in November 2017. This toolkit is very popular and has a huge user community. Nowadays, it is open-sourced and maintained independently by several companies. It follows a multilayered data model with scalable data collection and a user-friendly query language. It has multiple features and aspects to alert the client-side instrumentation.

Features of Prometheus?

What are metrics?The numeric measurement of time is Metrics. These measurements have been recorded a plentiful of times. Any database, website, or application must be monitored for how much time it takes for interactions. Metrics have an important role in determining the flexibility of any application.

Multidimensional data model

PromQL (query language)

Time series collection over HTTP

Single and autonomous database storage

Multiple modes for graphing and dashboarding

How Does It Work?

The data used in Prometheus have time stamps in a series called metrics. These time series are built in a pool model. Each metric has a different name for querying and referencing, while labeling is also possible with Prometheus. Each data source can have an added label, such as HTTP server code and other software application descriptions. Prometheus is also known as a multi-dimensional model for this ability, for its server aggregates the data to the data sources. Prometheus can store data in local disks, making queries and alerts even faster. It can store the data in remote storage too.

Benefits of Prometheus

The Prometheus server controls data scraping and storing metrics by scheduling the monitoring jobs. These jobs are configured by one or more scrap-config directives, making them quicker than other metrics recording software. Prometheus allows fast outage discovery which can be very speedily achieved in case of system failure.
