-## High Level Overview
-
-Free Monitoring is a way for MongoDB Community users to enable Cloud Monitoring on their database.
-To use Free Monitoring, a customer must first register by issuing the command
-`db.enableFreeMonitoring()`.
-
-The entire Free Monitoring subsystem is controlled by an object of type
-[`FreeMonController`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_controller.h#L53).
-The `FreeMonController` lives as a decoration on the `ServiceContext`. The `FreeMonController` has a
-two collections of collectors - the
-[`_registrationCollectors`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_controller.h#L197)
-which collect data at registration time, and the
-[`_metricCollectors`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_controller.h#L200)
-which collect data periodically. It also owns a
-[`FreeMonProcessor`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.h#L304)
-which under the hood contains a multi-producer priority queue, and a
-[`FreeMonNetworkInterface`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_network.h#L40)
-which is a way for the subsystem to send and receive packets to the cloud endpoint.
-
-When the server first starts, if Free Monitoring is enabled (using a command line parameter
-`enableFreeMonitoring`), the FreeMonController is initialized on server startup through the mongod
-main function which calls
-[`startFreeMonitoring`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_mongod.cpp#L310).
-This function creates the
-[`FreeMonNetworkInterface`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_mongod.cpp#L322),
-initializes the controller, determines the Registration type, and calls
-[`start`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_mongod.cpp#L346-L348)
-on the controller. The
-[`start`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_controller.h#L59-L65)
-function initializes the processor, creates a thread for it to run on, and performs registration if
-the user has performed registration.
-
-If the user has not performed registration, the metrics collector begins collecting data. It stores
-this data in a MetricsBuffer, capable of holding up to 10 data points. When the user performs
-registration, a call to
-[`registerServerStartup`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_controller.cpp#L79-L84)
-is made, placing a
-[`FreeMonMessageWithPayload`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_message.h#L255)
-object in the processor's queue. A `FreeMonMessageWithPayload` is an expanded subclass of
-[`FreeMonMessage`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_message.h#L146),
-which represents a message sent to the
-[`FreeMonProcessor`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.h#L304)
-actor to process and make a decision. For more reading on the actor model that the Free Monitoring
-system is based on, see [here](https://en.wikipedia.org/wiki/Actor_model). A `FreeMonMessage` has
-two significant properties, a type and a deadline. The type determines how the queue responds when
-processing the message. The code for how the queue processes messages can be found
-[here](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L156-L269).
-The deadline determines the priority of the message in the queue. The deadline represents both the
-waiting period the queue must take to process a message and a priority the queue uses to determine
-the order in which messages are processed. For example, a message with a deadline of now can be
-processed before something with a deadline of an hour from now.
-
-In the call to
-[`registerServerStartup`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_controller.cpp#L79-L84),
-a message of type `RegisterServer` is sent to the queue. Included with the message is a payload of
-the registration type that the server should perform. The queue processes this message and calls
-[`doServerRegister`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L324)
-with the message object. The function processes the `RegistrationType` and if it is
-`RegisterOnStart`, sends a `RegisterCommand` message to the queue. If the `RegistrationType` is
-something else, we try to determine whether we are a primary or secondary in a replica set and send
-a message depending on the state of free monitoring in the set. The full logic with comments is
-[here](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L330-L367),
-but know that it may create a `RegisterCommand` message to the queue in certain cases. The function
-[`doServerRegister`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L328)
-also creates a message of type `MetricsCollect` in the queue.
-
-When the queue processes the
-[`RegisterCommand`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L173-L175)
-message, it calls
-[`doCommandRegister`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L406)
-which uses the
-[`FreeMonNetworkInterface`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_mongod.cpp#L322)
-to send a message over the wire to the cloud endpoint. It also writes the registration state
-(`FreeMonRegistrationStatus::kPending`) and registration information out to disk, calling
-[`writeState`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L299),
-which invokes functions on the
-[`FreeMonStorage`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_storage.h#L43)
-class. The job of the `FreeMonStorage` class is to provide an interface for different functions to
-interact with the storage subsystem. Whenever a change is made to the registration state -
-registration completes or registration is cancelled because of an endpoint error - the processor
-writes this information out to disk.
-
-The queue also processes the first `MetricsCollect` command around this time. The queue reads the
-Metrics collect method and calls
-[`doMetricsCollect`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L714-L726)
-which fires the `_metrics` collectors to collect and stores the data in a
-[`MetricsBuffer`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.h#L185-L225).
-The buffer can hold 10 data points at a time, so if the data has not been synced to the cloud
-endpoint by the time the 11th data point is collected, then the buffer will remove the last item
-from the queue. The function
-[`doMetricsCollect`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L724-L725)
-creates another message of type `MetricsCollect` with a deadline of the specified
-`_metricsGatherInterval` for collection.
-
-The way for a queue to trigger sending new metrics to the server is by sending a message of type
-`MetricsSend`. This occurs on a few occasions - when registration information has been successfully
-[sent to the cloud
-endpoint](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L666),
-when metrics information has [successfully been sent to the cloud
-endpoint](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L865-L866),
-and when metrics information has [failed to send to the
-endpoint](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.cpp#L886-L888).
-In the first case, a message is created with a deadline of now. In the second case the message is
-sent with a deadline that is tracked by the
-[`MetricsRetryCounter`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_processor.h#L153-L183)
-object. The retry object is used to track any failures the processor encountered when sending
-metrics; if enough failures have occured in a row, then the processor stops sending the metrics. In
-the third case, the `MetricsRetryCounter` object is incremented to indicate failure. If it has not
-exceeded the retry limit, then the message is again sent with a deadline tracked by the retry
-object.
-
-The last notable part of `FreeMonitoring` is the
-[`FreeMonOpObserver`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_op_observer.h#L40).
-This `OpObserver` watches the namespace where the free monitoring registration information is stored
-(the `admin` database and the `system.version` collection) and sends a message to the processor if
-there is a change to the document for the registration information. For example, if someone updates
-the document, the OpObserver calls
-[`notifyOnUpsert`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_controller.h#L133-L138)
-in the controller, the controller queues a
-[`NotifyOnUpsert`](https://github.com/mongodb/mongo/blob/r4.4.0/src/mongo/db/free_mon/free_mon_controller.cpp#L111)
-command in the processor. When the processor reads that message, it reads the updated registration
-state from disk and updates the free monitoring subsystem based on the new information.
