prometheus-net SystemMetrics

NuGet version  Build Status

prometheus-net SystemMetrics allows you to export various system metrics (such as CPU usage, disk usage, etc) from your .NET application to Prometheus. It is designed to be a very lightweight alternative to node_exporter, only containing essential metrics. This is useful on systems with limited RAM or where it is easier to add this library to your app instead of deploying a totally separate service.


Install the prometheus-net.SystemMetrics library using NuGet.

Add the services to your Startup.cs:

using Prometheus.SystemMetrics;

public void ConfigureServices(IServiceCollection services)
    // ...

If you have not already done so, you will also need to expose the Prometheus metrics endpoint by calling MapMetrics in Configure:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    // ...
    app.UseEndpoints(endpoints =>
        // ...

After doing this, going to /metrics should return the new metrics.


By default, this will add all the collectors. To only add some collectors, you can instead only render the collectors you want to use:

services.AddSystemMetrics(registerDefaultCollectors: false);


Where possible, metrics have the same name and format as node_exporter.


The number of seconds the CPU has spent in each mode (system, user, idle, etc). Available on Linux and Windows. Example data:

node_cpu_seconds_total{cpu="0",mode="system"} 172.35
node_cpu_seconds_total{cpu="0",mode="user"} 292.27
node_cpu_seconds_total{cpu="0",mode="idle"} 30760.4


The amount of free disk space on all mounts. Available on all platforms. Example data:

# Linux
node_filesystem_avail_bytes{mountpoint="/",fstype="ext4"} 57061916672

# Windows
node_filesystem_avail_bytes{mountpoint="C:\\",fstype="NTFS"} 101531594752

Load Average

Available on Linux. Example data:

node_load1 0.06
node_load5 0.03
node_load15 0.26


Stats such as available RAM, RAM used by caches, etc. Available on Linux and Windows. Example data:

node_memory_MemAvailable_bytes 1527701504
node_memory_Cached_bytes 572964864
node_memory_MemFree_bytes 961966080
node_memory_MemTotal_bytes 2085904384


Total amount of data sent and received over the network. Available on all platforms. Example data:

node_network_transmit_bytes_total{device="eth0"} 3053723
node_network_receive_bytes_total{device="eth0"} 5822231


2.0.0 - 8th October 2021

  • Added memory and CPU collectors for Windows (thanks to @masterworgen for the initial implementation in PR #3)
  • Added .NET Framework 4.6.2 builds, since prometheus-net itself supports this framework version.

1.0.1 - 17th May 2020

  • Added memory stats for Linux
  • Added total file size to disk collector
