Once the services are identified and the targets are ready then we can pull metrics from it and can scrape the target. Through Service discovery we monitor the entities and can also locate its targets. To Pull metrics, identification of services and finding the targets are compulsory needed. With the help of Service discovery the services are identified which are need to scraped. Next and very important component of Prometheus Server is the Service Discovery. PromQL allows the user to select and aggregate the data. PromQL which is very powerful querying language. Prometheus uses its own query language i.e. Prometheus has many interfaces that allow integrating with remote storage systems. Storage in Prometheus server has a local on disk storage. In Prometheus server data is scraped from the target nodes and then stored int the database. Prometheus server is a core of Prometheus architecture which is divided into several parts like Storage, PromQL, HTTP server, etc. Prometheus server is a first component of Prometheus architecture. Now lets understand the Prometheus components one-by-one Prometheus Components 1. We made a basic design to understand it easily for you people. As above we can see an architecture of Prometheus monitoring tool. Prometheus use multiple modes used for graphing and dashboarding support. In Prometheus tabs are on and handles hundreds of services and microservices. Prometheus uses a powerful query language i.e. Prometheus has changed the way of monitoring systems and that is why it has become the Top-Level project of Cloud Native Computing Foundation (CNCF). Prometheus is a open source Linux Server Monitoring tool mainly used for metrics monitoring, event monitoring, alert management, etc. Creating Grafana Dashboard to Monitor Linux Server Configure the Node Exporter as a Prometheus target #GRAFANA NODE EXPORTER INSTALL#
Install Node Exporter on Linux (CentOS, RedHat, Amazon Linux 2) Configure Prometheus as Grafana DataSource
#13.Install Grafana on Linux (CentOS, RedHat, Amazon Linux 2). #GRAFANA NODE EXPORTER UPDATE#
Update Prometheus ownership on Directories Update Prometheus user ownership on Binaries
#4.Install Prometheus and Grafana on Linux. Creating Prometheus System Users and Directory Now, let’s check if the Prometheus instance is up and running and in particular if it is able to connect successfully to the Node Exporter running process. Now, let’s create the prometheus.yml file containing the Prometheus configuration, into the same folder of docker-compose.yml: global: scrape_interval: 10s scrape_configs: - job_name: myvm metrics_path: /metrics static_configs: - targets: 
# TYPE go_gc_duration_seconds summary go_gc_duration_seconds/prometheus.yml:/etc/prometheus/prometheus.yml grafana: image: grafana/grafana:8.4.4-ubuntu container_name: grafana networks: - mynetwork ports: - "3000:3000" Verify that the Node Exporter script is monitoring correctly the Virtual Machine executing the following command from inside the VM: curl You should see an output like this: # HELP go_gc_duration_seconds A summary of the GC invocation durations. Node exporter setupĭownload and execute Node Exporter: wget tar xvfz node_exporter-1.3.1. The metrics generated by Node Exporter are sampled by the Prometheus time-series database.įinally, Grafana is able to queries the Prometheus database thanks to its native Prometheus data source.

It only needs to download and execute it into the VM and it starts to collect many useful metrics about the machine, like CPU load, RAM load, Network I/O, etc. The monitoring of a linux virtual machine (VM) is made easy thanks to a ready-to-use script in Go language named “Node exporter”. Grafana is an open-source platform for monitoring and observability that allows you to query, visualize, alert on and understand your metrics no matter where they are stored.
#GRAFANA NODE EXPORTER SERIES#
Prometheus is an open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach. Node exporter is a Prometheus exporter script that is able to monitor the virtual machine on which it is running. Infrastructure overview What is “Node Exporter”?
