how do i add data to prometheus

Can you push data to Prometheus?

The Prometheus Pushgateway allows you to push time series from short-lived service-level batch jobs to an intermediary job which Prometheus can scrape. Combined with Prometheus's simple text-based exposition format, this makes it easy to instrument even shell scripts without a client library.

Where does Prometheus get data from?

Prometheus gathers metrics from different systems by scraping data from HTTP endpoints. It uses this information to identify issues, such as when an endpoint is missing or should not exist or when a time-series pattern indicates a problem.

What is endpoint in Prometheus?

In Prometheus terms, an endpoint you can scrape is called an instance, usually corresponding to a single process. A collection of instances with the same purpose, a process replicated for scalability or reliability for example, is called a job.

You can access the Prometheus UI in your browser at the URL http://localhost:9090 . If you are using Cloud Shell for this step, you can get access by using the Web Preview button.

How long is data stored in Prometheus?

By default the retention is configured to 15 days. The amounts of data stored on disk depends on retention — higher retention means more data on disk. The lowest supported retention in Prometheus is 2 hours (2h). Such a retention could be useful when configuring remote storage for Prometheus.

What is database of Prometheus?

Prometheus is a free software application used for event monitoring and alerting. It records real-time metrics in a time series database (allowing for high dimensionality) built using a HTTP pull model, with flexible queries and real-time alerting.

In what data format does Prometheus store data?

Prometheus fundamentally stores all data as time series: streams of timestamped values belonging to the same metric and the same set of labeled dimensions. Besides stored time series, Prometheus may generate temporary derived time series as the result of queries.

How do I import data into Grafana?

Import a Grafana dashboardOn the create tab, select Import.Paste the ID of the dashboard you want to import and click Load.Select the Data Source as Prometheus and click Import. Note. Prometheus is an open source systems monitoring system for which Grafana provides out-of-the-box support.

What is the difference between Grafana and Prometheus?

Prometheus collects rich metrics and provides a powerful querying language; Grafana transforms metrics into meaningful visualizations. Both are compatible with many, if not most, data source types. In fact, it is very common for DevOps teams to run Grafana on top of Prometheus.

How do I import a CSV file into Grafana?

Installing on a local Grafana:Install the Data Source. Use the grafana-cli tool to install CSV from the commandline: grafana-cli plugins install.Configure the Data Source. Accessed from the Grafana main menu, newly installed data sources can be added immediately within the Data Sources section.

How does Prometheus scrape data?

Configuring Prometheus to monitor itself Prometheus collects metrics from targets by scraping metrics HTTP endpoints. Since Prometheus exposes data in the same manner about itself, it can also scrape and monitor its own health. For a complete specification of configuration options, see the configuration documentation.

How does Prometheus monitoring work?

Prometheus scrapes metrics from instrumented jobs, either directly or via an intermediary push gateway for short-lived jobs. It stores all scraped samples locally and runs rules over this data to either aggregate and record new time series from existing data or generate alerts.

In what data format does Prometheus store data?

Prometheus fundamentally stores all data as time series: streams of timestamped values belonging to the same metric and the same set of labeled dimensions. Besides stored time series, Prometheus may generate temporary derived time series as the result of queries.

What is the method that Prometheus uses to acquire metrics and info?

Prometheus uses a pull model to collect these metrics; that is, Prometheus scrapes HTTP endpoints that expose metrics. Those endpoints can be natively exposed by the component being monitored or exposed via one of the hundreds of Prometheus exporters built by the community.

What is Grafana dashboard?

Grafana is the leading graph and dashboard builder for visualizing time series infrastructure and application metrics, but many use it in other domains including industrial sensors, home automation, weather, and process control. It provides a powerful and elegant way to create, explore, and share dashboards and data with your team and the world.
