What’s Prometheus?
Prometheus is a toolkit for monitoring and alerting that was created to gather and manage utility metrics. The Prometheus server was initially developed at SoundCloud earlier than it grew to become an open-source software.
Prometheus is a time-series database for end-to-end monitoring of time-series information. Time-series metrics are a set of knowledge that’s taken at common intervals comparable to month-to-month gross sales information, or each day utility visitors. Clear visibility into this sort of information affords insights into patterns, developments and predictions for enterprise planning. As soon as built-in with a number, Prometheus gathers utility metrics which can be associated to devoted capabilities that DevOps groups wish to monitor.
Prometheus metrics present information factors that include the metric title, label, timestamp and worth through the use of a question language known as PromQL. PromQL permits builders and IT departments to combination information metrics and switch them into histograms–graphs and dashboards for larger visualization. Prometheus can entry information from enterprise databases or from exporters. Exporters are software program that’s associated to purposes that work to drag metrics from varied apps and endpoints.
Prometheus collects 4 sorts of metrics:
Counters: Countersmeasure cumulative numerical values that solely enhance. Counters are used to measure accomplished duties, the variety of errors that occurred throughout an outlined interval, or the variety of operating processes or microservices.
Gauges: Gauges monitor numerical values that rise and fall relying on exterior elements. They’ll monitor CPU and reminiscence utilization, temperature, or the scale of a queue.
Histograms: Histograms measure the length of specified occasions comparable to request length or response measurement. They then divide the vary of those measurements into intervals which can be known as buckets and decide what number of of those measurements fall into every respective bucket.
Summaries: Like histograms, summaries additionally measure request durations and response measurement, but additionally present a complete rely of all observations and a complete of all noticed values.
One other helpful facet of Prometheus is that it may possibly create accessible dashboards and graphs primarily based on the collected information.
