FAQ: What are exporters in Prometheus?

A Prometheus Exporter is a piece of software that. Can fetch statistics from another, non-Prometheus system. Can turn those statistics into Prometheus metrics, using a client library. Starts a web server that exposes a /metrics URL, and have that URL display the system metrics.

How do Prometheus exporters work?

An exporter is comprised of software features that produce metrics data, and an HTTP server that exposes the generated metrics available via a given endpoint. Metrics are exposed according to a specific format that the Prometheus server can read and ingest (scraping).

What is the use of node exporter in Prometheus?

The node exporter enables you to measure various machine resources such as memory, disk and CPU utilization. For installations from source you must install and configure it yourself. To enable the node exporter: Enable Prometheus.

How do I export data from Prometheus?

There is no export and especially no import feature for Prometheus. If you need to keep data collected by prometheus for some reason, consider using the remote write interface to write it somewhere suitable for archival, such as InfluxDB (configured as a time-series database).

What are Prometheus metrics?

Prometheus is a metrics collection and alerting tool developed and released to open source by SoundCloud. Prometheus is similar in design to Google’s Borgmon monitoring system, and a relatively modest system can handle collecting hundreds of thousands of metrics every second.

What is the difference between Prometheus and Grafana?

Grafana and Prometheus, both help us in tackling issues related to complex data in a simplified manner. Grafana is an open-source visualization software, which helps the users to understand the complex data with the help of data metrics. Prometheus is an open-source event monitoring and alerting tool.

What is the node exporter?

Node Exporter is a Prometheus exporter for server level and OS level metrics with configurable metric collectors. It helps us in measuring various server resources such as RAM, disk space, and CPU utilization.

What is WMI exporter?

The WMI exporter is an awesome exporter for Windows Servers. It will export metrics such as the CPU usage, the memory and the disk I/O usage. The WMI exporter can also be used to monitor IIS sites and applications, the network interfaces, the services and even the local temperature!

How do I create a node exporter service?

Create a Custom Node Exporter Service Step 1: Create a node_exporter user to run the node exporter service. Step 2: Create a node_exporter service file under systemd. Step 3: Add the following service file content to the service file and save it. Step 4: Reload the system daemon and star the node exporter service.

What is Process exporter?

Prometheus exporter that mines /proc to report on selected processes. Some apps are impractical to instrument directly, either because you don’t control the code or they’re written in a language that isn’t easy to instrument with Prometheus.

What exporter means?

How do I create a custom exporter for Prometheus?

Exporter will convert the result payload into Metrics.

  1. Setup GO and Package Dependencies. Follow the steps on https://golang.org/doc/install.
  2. Create Entry-point and Import Dependencies.
  3. Put in Entry-point function main()
  4. Add prometheus metrics endpoint and listen on the server port.
  5. Explore External Services API with curl.

Is Prometheus better than Zabbix?

Zabbix is written in C and PHP, it’s more classic-monitoring. Prometheus is written in Go, it’s recommended for Cloud, SaaS/openstack monitoring. BUT you can use both, Prometheus is faster because of the database zabbix has a smaller footprint(because its written in c).

What is scraping in Prometheus?

Metrics collection with Prometheus relies on the pull model, meaning that Prometheus is responsible for getting metrics (scraping) from the services that it monitors. This is diametrically opposed from other tools like Graphite, which are passively waiting on clients to push their metrics to a known server.

Is Prometheus push or pull?

Prometheus by design implements a pull-based approach for collecting metrics. For most of us, this is a departure from the push-based monitoring systems we’ve been using for the past decade.
