What is Prometheus Node Exporter A Prometheus Exporter can fetch statistics from an application in the format used by that system (i.e. XML), convert those statistics into metrics that Prometheus can utilize, and then expose them on a Prometheus-friendly URL.These exporters collect particular metrics from the target systems and deliver them in a Prometheus-readable way. A variety of metrics, including CPU, memory, disk I/O, network statistics, and custom application-specific metrics, can be included.HTTP port 9100
The node_exporter listens on HTTP port 9100 by default.
How do I know if Prometheus exporter is running : To verify that node_exporter is running, open your browser and navigate to http://<IP of Node exporter host>:9100/metrics. All the metrics collected will be displayed; these are the same metrics Prometheus will scrape.
What is the difference between Prometheus node exporter and Pushgateway
For machine-level metrics, the textfile collector of the Node exporter is usually more appropriate. The Pushgateway is intended for service-level metrics. The Pushgateway is not an event store.
How does Prometheus pull data : 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.
Machine where we haven't installed anything before so we will first install prometheus server then we are going to install node exporter. And then we are going to install grafana server. So these are Node Exporter Setup on Linux Nodes
Create a node_exporter user to run the node exporter service. sudo useradd -rs /bin/false node_exporter.
Create a node_exporter service file under systemd.
Reload the system daemon and start the node exporter service.
What is the difference between Prometheus and node exporter
The Node Exporter is an agent that gathers system metrics and exposes them in a format which can be ingested by Prometheus. The Node Exporter is a project that is maintained through the Prometheus project. This is a completely optional step and can be skipped if you do not wish to gather system metrics.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.Grafana supports pushing metrics to Graphite or exposing them to be scraped by Prometheus. The Prometheus pull model requires your Prometheus system to know all the targets. This is achieved through Prometheus Service Discovery. Prometheus Service Discovery allows you to automatically discover and monitor services in your environment.
What is Pushgateway in Prometheus : A Prometheus Pushgateway acts as a kind of intermediate service or “gateway” (hence the name), storing these pushed metrics until the next scrape interval. Since Prometheus is an open-source project, you can view the Pushgateway source code on github.com.
What is the difference between collector and exporter in Prometheus : A collector is a part of an exporter that represents a set of metrics. It may be a single metric if it is part of direct instrumentation, or many metrics if it is pulling metrics from another system.
What is the difference between push and pull observability
The Pull-based monitoring system, as the name implies, is a monitoring system that actively obtains indicators, and the objects that require monitoring need to have the capability to be accessed remotely. Push-based monitoring systems do not actively obtain data, but the monitored objects actively push indicators. To send metrics to Pushgateway from batch jobs, you can use web requests or client libraries in languages like Powershell or Bash. Pushgateway labels, such as job and instance, are used for grouping metrics and can be added via the URL to make metrics discoverable by Prometheus.The Prometheus pull model requires your Prometheus system to know all the targets. This is achieved through Prometheus Service Discovery. Prometheus Service Discovery allows you to automatically discover and monitor services in your environment.
Does Grafana pull from Prometheus : Grafana dashboards consist of visualizations populated by data queried from the Prometheus data source.
