The exporter collects such metrics as: This database-agnostic exporter collects and exposes metrics for SQL-based database management systems. An exporter is considered essential in any cloud-native ecosystem that includes applications that don't expose Prometheus-supported metrics by default. Create a prometheus folder and add the configuration file prometheus.yml as seen below: global: scrape_interval: 10s # By default, scrape targets every 15 seconds. and does not time out. Your review is pending approval, you can still make changes to it. Although manual scaling using federation is one option, the approach typically introduces manual overhead in configuration and maintenance. Prometheus offers a few free alternatives for visualizing time-series data in a user interface. In this section, well discuss how to build a basic exporter for a Kubernetes cluster using a Python script. On Windows targets, you would install the wmi_exporter rather than node_exporter. Test it by doing a manual scrape: You can filter the output to look at just a subset of metrics, like this: (-s = silent, stops curl showing the progress information). Exposes system information as provided by the uname system call. The exporter reports metrics that are useful in monitoring node (host and server) performance, such as: This exporter collects metrics from Windows hosts (both PCs and servers) and exposes them to the Prometheus server. Are you sure you want to create this branch?
