time series data base
- sequence of data points collected at regular intervals over a period of time
how prometheus good for time series metrics
- Prometheus fundamentally stores all data as time series: streams of timestamped values belonging to the same metric and the same set of labeled dimensions
components of prometheus
- prometheus server
- client libraries
- push gateway
- exporters
- alert manager
How does prometheus work
- by pushgateway:-The Pushgateway is an intermediary service which allows you to push metrics from jobs which cannot be scraped
- by prebuilt exporters:- You can write your own exporter/custom collector or use the prebuilt exporters which will collect data from your infrastructure and send it to Prometheus
- by instrumenting:– is the use of a library in an application’s code base in order to expose and update metrics about it for a Prometheus instance to scrape.
