1/11/2024 0 Comments Node exporter prometheus config![]() ![]() To do this, we will create a configuration file containing our exporter’s encrypted credentials.įirst, log in to our node01, and install the apache2-utils package, which we will use to create a hash for the password. Change the Service Itself on the Host Change the Prometheus Configuration File. The idea is first to implement authentication and then TLS encryption. Let’s assume we have a configuration with a Prometheus server that monitors one server with the Node Exporter configured as a service with minimal configuration. I will dedicate a separate blog post for securing the Prometheus server accesses using a reverse proxy like NGINX. This blog post will focus on securing communications between exporters and the Prometheus server by implementing authentication and TLS encryption. What is Prometheus Windows Exporter A windows exporter is a tool used by windows servers to collect metrics like memory, CPU and disk usage and also can be used as a monitoring system for information systems, network interfaces and applications. When it comes to exporters, many of them do provide some security features such as authentication and/or TLS encryption, and we can set up your Prometheus server configuration to interact with those secure exporters. Connect and share knowledge within a single location that is structured and easy to search. to extend Prometheuss configuration to scrape the node exporter as well. We can implement this security layer with an Apache or Nginx server configured as a reverse proxy that implements TLS encryption, authentication and other security features. tools that are often used in conjunction with Prometheus, such as Grafana and. One solution would be to secure the Prometheus server accesses using a reverse proxy, encrypting the communications between clients and a server. Prometheus server, for instance, does not provide authentication or TLS encryption out of the box, meaning anyone accessing the server’s HTTP endpoints can access all of our time-series data. ![]() ![]() However, regarding security, there are some essential things to consider. Install and run a Prometheus instance that is configured to discover the Node Exporter using the targets.json file Installing and running the Node Exporter See this section of the Monitoring Linux host metrics with the Node Exporter guide. Prometheus is a popular open-source monitoring system that helps track and alert for various applications. ![]()
