![]() b, -baseurl The Solr base URL (such as when Solr is running in Standalone mode. It can be any port not already in use on your server. This port will be used to configure Prometheus. p, -port The port where Prometheus will listen for new data. H, -help Displays command line help and usage. This graphic provides a more detailed view: Figure 1. If you use Prometheus and Grafana for metrics storage and data visualization, Solr includes a Prometheus exporter to collect metrics and other data.Ī Prometheus exporter ( solr-exporter) allows users to monitor not only Solr metrics which come from Metrics API, but also facet counts which come from Searching and responses to Collections API commands and PingRequestHandler requests.

It supports dynamic querying, alerting, and interactive exploration of data. Grafana provides a rich set of visualization options, such as graphs, charts, and tables, to represent the collected metrics in a user-friendly manner. It allows users to create customizable dashboards that display metrics and logs from various data sources, including Prometheus. Grafana is an open-source data visualization and analytics platform. Prometheus can scrape Node Exporter endpoints to collect and store these metrics for monitoring and analysis. These metrics provide insights into the overall health and performance of the cluster nodes. Node Exporter collects a wide range of metrics, including CPU usage, memory usage, disk usage, network statistics, and more. It runs as a daemonset in Kubernetes, deploying an instance o3n each node. Node Exporter is a Prometheus exporter specifically designed to gather metrics from the host operating system and hardware. It supports alerting based on user-defined rules and integrates well with visualization tools like Grafana. Prometheus also provides a flexible query language called PromQL for retrieving and aggregating metrics. The scraped data is stored in a time-series database, which allows for querying and analysis. Prometheus uses a pull-based model, where it regularly scrapes metrics from various targets, such as applications, services, and infrastructure components. It is designed to monitor highly dynamic environments like Kubernetes. Prometheus is an open-source monitoring and alerting system that collects and stores time-series data. Here's a brief definition and overview of each tool: Prometheus, Node Exporter, and Grafana are popular tools used for monitoring and observability in Kubernetes clusters.
