# Windows Performance Counters plugin.
# These are the recommended method of monitoring system metrics on windows,
# as the regular system plugins (inputs.cpu, inputs.mem, etc.) rely on WMI,
# which utilize more system resources.
#
# See more configuration examples at:
#   https://github.com/influxdata/telegraf/tree/master/plugins/inputs/win_perf_counters
# If metrics are missing run `lodctr /r` as Administrator

Run/Test GitLab CI Pipeline jobs locally

• cd into your project directory

Hints

• You probably need to use exec docker --docker-privileged when you want to use docker-in-docker (service docker:dind)
  • see https://docs.gitlab.com/ee/ci/docker/using_docker_build.html#use-the-docker-executor-with-docker-in-docker
• If you have issues with the Docker daemon not being reachable, you have 2 options:
  • disable TLS: exec docker --env DOCKER_TLS_CERTDIR=""
  • mount the certs: exec docker --docker-volumes "/certs/client"
