@@ -95,10 +95,10 @@ Some background:
 
 - `isReady` (added in v7.2.0 and v6.8.4) is a way for a usage collector to announce that some async process must finish first before it can return data in the `fetch` method (e.g. a client needs to ne initialized, or the task manager needs to run a task first). If any collector reports that it is not ready when we call its `fetch` method, we reset a flag to try again and, after a set amount of time, collect data from those collectors that are ready and skip any that are not. This means that if a collector returns `true` for `isReady` and it actually isn't ready to return data, there won't be telemetry data from that collector in that telemetry report (usually once per day). You should consider what it means if your collector doesn't return data in the first few documents when Kibana starts or, if we should wait for any other reason (e.g. the task manager needs to run your task first). If you need to tell telemetry collection to wait, you should implement this function with custom logic. If your `fetch` method can run without the need of any previous dependencies, then you can return true for `isReady` as shown in the example below.
 
-- The `fetch` method needs to support multiple contexts in which it is called. For example, when a user requests the example of what we collect in the **Kibana>Advanced Settings>Usage data** section, the clients provided in the context of the function (`CollectorFetchContext`) are scoped to that user's privileges. The reason is to avoid exposing via telemetry any data that user should not have access to (i.e.: if the user does not have access to certain indices, they shouldn't be allowed to see the number of documents that exists in it). In this case, the `fetch` method receives the clients `callCluster`, `esClient` and `soClient` scoped to the user who performed the HTTP API request. Alternatively, when requesting the usage data to be reported to the Remote Telemetry Service, the clients are scoped to the internal Kibana user (`kibana_system`). Please, mind it might have lower-level access than the default super-admin `elastic` test user.

Please, mind it might have lower-level access than the default super-admin `elastic` test user.   
 In some scenarios, your collector might need to maintain its own client. An example of that is the `monitoring` plugin, that maintains a connection to the Remote Monitoring Cluster to push its monitoring data. If that's the case, your plugin can opt-in to receive the additional `kibanaRequest` parameter by adding `extendFetchContext.kibanaRequest: true` to the collector's config: it will be appended to the context of the `fetch` method only if the request needs to be scoped to a user other than Kibana Internal, so beware that your collector will need to work for both scenarios (especially for the scenario when `kibanaRequest` is missing).
 
-Note: there will be many cases where you won't need to use the `callCluster`, `esClient` or `soClient` function that gets passed in to your `fetch` method at all. Your feature might have an accumulating value in server memory, or read something from the OS.

 In the case of using a custom SavedObjects client, it is up to the plugin to initialize the client to save the data and it is strongly recommended to scope that client to the `kibana_system` user.

 There are a few ways you can test that your usage collector is working properly.
 
-1. The `/api/stats?extended=true&legacy=true` HTTP API in Kibana (added in 6.4.0) will call the fetch methods of all the registered collectors, and add them to a stats object you can see in a browser or in curl. To test that your usage collector has been registered correctly and that it has the model of data you expected it to have, call that HTTP API manually and you should see a key in the `usage` object of the response named after your usage collector's `type` field. This method tests the Metricbeat scenario described above where `callCluster` wraps `callWithRequest`.

This method tests the Metricbeat scenario described above where the elasticsearch client wraps the call with the request.
 2. There is a dev script in x-pack that will give a sample of a payload of data that gets sent up to the telemetry cluster for the sending phase of telemetry. Collected data comes from:
     - The `.monitoring-*` indices, when Monitoring is enabled. Monitoring enhances the sent payload of telemetry by producing usage data potentially of multiple clusters that exist in the monitoring data. Monitoring data is time-based, and the time frame of collection is the last 15 minutes.
     - Live-pulled from ES API endpoints. This will get just real-time stats without context of historical data.
