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 turned an open-source instrument.
Prometheus is a time-series database for end-to-end monitoring of time-series information. Time-series metrics are a group of information that’s taken at common intervals resembling month-to-month gross sales information, or each day utility site visitors. Clear visibility into the sort of information presents 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 features that DevOps groups need to monitor.
Prometheus metrics present information factors that encompass the metric title, label, timestamp and worth through the use of a question language referred to as PromQL. PromQL permits builders and IT departments to mixture information metrics and switch them into histograms–graphs and dashboards for higher visualization. Prometheus can entry information from enterprise databases or from exporters. Exporters are software program that’s associated to functions that work to drag metrics from numerous apps and endpoints.
Prometheus collects 4 kinds 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 working processes or microservices.
Gauges: Gauges monitor numerical values that rise and fall relying on exterior elements. They will monitor CPU and reminiscence utilization, temperature, or the scale of a queue.
Histograms: Histograms measure the period of specified occasions resembling request period or response measurement. They then divide the vary of those measurements into intervals which can be referred to 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 in addition present a complete rely of all observations and a complete of all noticed values.
