systemctl reload hidra_exporter

# Description of the sample
description: "This is a sample to test the HTTP plugin"
# Tags is a key-value list of tags that will be added to the sample. You can add here whatever you want.
tags:
  tenant: "hidra"
# Interval is the time between each execution of the sample.
interval: "1m"
# Timeout is the time that Hidra will wait for the sample to finish.
timeout: "10s"
# Steps is a list of steps that will be executed in order.
steps:
    # Plugin is the name of the plugin that will be used to execute the step.
  - plugin: http
    # Action is the action that will be executed by the plugin.
    action: request
    # Parameters is a key-value list of parameters that will be passed to the plugin.
    parameters:
      url: https://google.com/
  - plugin: http
    action: statusCodeShouldBe
    parameters:
      statusCode: 301
