Metrics collectors are +pre-installed with every Netdata Agent and usually require zero configuration. Netdata also collects and visualizes +resource utilization per application on Linux systems using `apps.plugin`. + +[**apps.plugin**](https://github.com/netdata/netdata/blob/master/collectors/apps.plugin/README.md) looks at the Linux process tree every second, much like `top` or +`ps fax`, and collects resource utilization information on every running process. By reading the process tree, Netdata +shows CPU, disk, networking, processes, and eBPF for every application or Linux user. Unlike `top` or `ps fax`, Netdata +adds a layer of meaningful visualization on top of the process tree metrics, such as grouping applications into useful +dimensions, and then creates per-application charts under the **Applications** section of a Netdata dashboard, per-user +charts under **Users**, and per-user group charts under **User Groups**. + +Our most popular application collectors: + +- [Prometheus endpoints](https://github.com/netdata/go.d.plugin/blob/master/modules/prometheus/README.md): Gathers + metrics from one or more Prometheus endpoints that use the OpenMetrics exposition format. Auto-detects more than 600 + endpoints. +- [Web server logs (Apache, NGINX)](https://github.com/netdata/go.d.plugin/blob/master/modules/weblog/README.md): + Tail access logs and provide very detailed web server performance statistics. This module is able to parse 200k+ + rows in less than half a second. +- [MySQL](https://github.com/netdata/go.d.plugin/blob/master/modules/mysql/README.md): Collect database global, + replication, and per-user statistics. +- [Redis](https://github.com/netdata/go.d.plugin/blob/master/modules/redis/README.md): Monitor database status by + reading the server's response to the `INFO` command. +- [Apache](https://github.com/netdata/go.d.plugin/blob/master/modules/apache/README.md): Collect Apache web server + performance metrics via the `server-status?auto` endpoint. +- [Nginx](https://github.com/netdata/go.d.plugin/blob/master/modules/nginx/README.md): Monitor web server status + information by gathering metrics via `ngx_http_stub_status_module`. +- [Postgres](https://github.com/netdata/go.d.plugin/blob/master/modules/postgres/README.md): Collect database health + and performance metrics. +- [ElasticSearch](https://github.com/netdata/go.d.plugin/blob/master/modules/elasticsearch/README.md): Collect search + engine performance and health statistics. Optionally collects per-index metrics. +- [PHP-FPM](https://github.com/netdata/go.d.plugin/blob/master/modules/phpfpm/README.md): Collect application summary + and processes health metrics by scraping the status page (`/status?full`). + +Our [supported collectors list](https://github.com/netdata/netdata/blob/master/collectors/COLLECTORS.md#service-and-application-collectors) shows all Netdata's +application metrics collectors, including those for containers/k8s clusters. + +## Collect metrics from applications running on Windows + +Netdata is fully capable of collecting and visualizing metrics from applications running on Windows systems. The only +caveat is that you must [install Netdata](https://github.com/netdata/netdata/blob/master/packaging/installer/README.md) on a separate system or a compatible VM because there +is no native Windows version of the Netdata Agent. + +Once you have Netdata running on that separate system, you can follow the [collectors configuration reference](https://github.com/netdata/netdata/blob/master/collectors/REFERENCE.md) documentation to tell the collector to look for exposed metrics on the Windows system's IP +address or hostname, plus the applicable port. + +For example, you have a MySQL database with a root password of `my-secret-pw` running on a Windows system with the IP +address 203.0.113.0. you can configure the [MySQL +collector](https://github.com/netdata/go.d.plugin/blob/master/modules/mysql/README.md) to look at `203.0.113.0:3306`: + +```yml +jobs: + - name: local + dsn: root:my-secret-pw@tcp(203.0.113.0:3306)/ +``` + +This same logic applies to any application in our [supported collectors +list](https://github.com/netdata/netdata/blob/master/collectors/COLLECTORS.md#service-and-application-collectors) that can run on Windows. + +## What's next? + +If you haven't yet seen the [supported collectors list](https://github.com/netdata/netdata/blob/master/collectors/COLLECTORS.md) give it a once-over for any +additional applications you may want to monitor using Netdata's native collectors, or the [generic Prometheus +collector](https://github.com/netdata/go.d.plugin/blob/master/modules/prometheus/README.md). + +Collecting all the available metrics on your nodes, and across your entire infrastructure, is just one piece of the +puzzle.
