The following Grafana dashboard image shows a Disk I/O graph of raw data from Prometheus derived from a laptop.
#PROMETHEUS MONITORING POSTGRESQL SOFTWARE#
Prometheus and similar software provide tools to compact and optimize time series data. You can store time series data in any relational database, however, these systems are not developed to store and query large volumes of time series data. a set of labels called dimensions, for example, job and device.metrics that consist of a timestamp and a sample, which is the numeric value, such as how many disk bytes have been read or a stock price.Time series are fundamental to Prometheus its data model is arranged into: Prometheus is a technology that collects and stores time series data. This data is simply some measurement (such as a company stock price or Disk I/O) through a series of time instants. This type of time series data appears everywhere in systems monitoring, as well as in places such as seasonal temperature charts and stock prices. The X-axis is a moment in time and the Y-axis is a number or measurement for example, 5 megabytes per second. Disk I/O dashboardĭata like these form time series. The green line represents disk reads, and the yellow line represents writes.
#PROMETHEUS MONITORING POSTGRESQL MAC#
The following panel in a Grafana dashboard shows how much disk bandwidth on a Mac laptop is being used. In 2018, Prometheus graduated from Cloud Native Computing Foundation (CNCF) incubation, and today has a thriving community. Prometheus offers both a robust data model and a query language. Prometheus began in 2012 at SoundCloud because existing technologies were insufficient for their observability needs. Understanding Prometheus basics, why it’s valuable for system observability, and how users use it in practice will both help you better understand it and help you use Grafana. Prometheus is a core technology for monitoring and observability of systems, but the term “Prometheus” can be confusing because it is used in different contexts. Observability focuses on understanding the internal state of your systems based on the data they produce, which helps determine if your infrastructure is healthy.
