## Management Zones configuration

### Excluding noisy services

*If you find services that are not relevant for the analysis, you can exclude them from the MZ.*

#### HealthResource, PingResource, PrometheusResource services

*After the deployment of the OneAgent, your services should appear under Transactions & Services. A good practice would be to exclude*
*the ones that are not relevant for monitoring. i.e. For some BMW's teams, HealthResource, PingResource, PrometheusResource have been excluded.* 

**How to exclude HealthResource?**
1. Open the file *default.json* configuration under the *CD_<app_name>/management-zone/* folder.
2. Copy the following rule template:
	```
	{
     "comparisonInfo": {
      "caseSensitive": true,
      "negate": true,
      "operator": "CONTAINS",
      "type": "STRING",
      "value": "HealthResource"
     },
     "key": {
      "attribute": "SERVICE_NAME"
     }
    }
	```
2. Add it under the `"type": "SERVICE"` rule's conditions. It should look like this:
  ```
  {
   "conditions": [
    {
     "comparisonInfo": {
      "negate": false,
      "operator": "EQUALS",
      "type": "TAG",
      "value": {
       "context": "CONTEXTLESS",
       "key": "Component",
       "value": "{{.tag}}"
      },
	  {
     "comparisonInfo": {
      "caseSensitive": true,
      "negate": true,
      "operator": "CONTAINS",
      "type": "STRING",
      "value": "HealthResource"
     },
     "key": {
      "attribute": "SERVICE_NAME"
     }
    }
     },
     "key": {
      "attribute": "SERVICE_TAGS"
     }
    }
   ],
   "enabled": true,
   "propagationTypes": [
    "SERVICE_TO_PROCESS_GROUP_LIKE",
    "SERVICE_TO_HOST_LIKE"
   ],
   "type": "SERVICE"
  }
	```
	
3. Commit and pull request to merge the branch to the master:
	```
    git add <changes>
    git commit -m "<app_name> configuration changes"
	git push -u origin <branch>
	```
Note: you can use the same logic to exclude (or include) any other entity to your Management Zone.
