Hi Team, I am trying to add the CPU Core details on the prometheus dashboard, i have got the sample json file from the link " [CPU Utilization Details (Cores) | Grafana Labs](https://grafana.com/grafana/dashboards/4151/revisions) " In that it is asking for $host – which value i have to provide in it could you please help me on this. Thanks, Vamshi. ---

Hi Vamshi, Can you try this one: [Grafana](https://pmmdemo.percona.com/graph/d/node-cpu/cpu-utilization-details?inspect=22&inspectTab=json)? The one in your link I believe is from PMM v1. If you’re using v2, it might not work. ---

Hi Vamshi, Variable $host is formed by values of parameter _instance_ for node\_cpu metrics. ![Screenshot_20210324_104524](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/8/8e63ac553edc327d6c3d917f169a506063095b30.png) You should check what parameters names are used in your installation. The easiest way is to use Explore page. e.g. Parameter node\_name is used in PMM2 ![Screenshot_20210324_121520](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/9/9c4b3c0b3941d4439dfbe78bcb05a92400bd2d24.png) ---

You may use a docker exporter and add it for PMM monitoring as an external service. e.g. ![Screenshot_20210324_152923](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/1/1db4f2732ef08ac606a81f0e37334d7268642b8c.png) ![Screenshot_20210324_151952](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/c/c40c0a931700f9636be11f89b6a442d0e7eeae8c.png) ---

No docker exporter is included into pmm2-client package. So you should use any available exporter that fetches docker metrics. Next exporter is used in the provided earlier example. > **[GitHub - prometheus-net/docker\_exporter: Exports metrics about a Docker...](https://github.com/prometheus-net/docker_exporter)** > > Exports metrics about a Docker installation.
