laymanstake / PrometheusGrafanaSetup.ps1
Last active October 24, 2022 16:40
PowerShell script, which can download almost all the latest packages (except nssm, which is not github hosted) and then proceed to configure them on the same machine. Functions to download and create services are created in a way that select set of package can be downloaded or installed as putting everything on the same server may not be good idea.
