Note

Groups and projects are synonymous terms. Your {PROJECT-ID} is the same as your project id. For existing groups, your group/project id remains the same. This page uses the more familiar term group when referring to descriptions. The endpoint remains as stated in the document.

Start monitoring a new MongoDB process. The Monitoring starts monitoring the MongoDB process on the hostname and port you specify. Ops Manager knows only the information that you provide. The response document includes blank values until Ops Manager completes discovery of the MongoDB processes configuration.

Request Path Parameters¶

`Parameter`	Type	Necessity	Description
`PROJECT-ID`	string	Required	Unique identifier of the project that owns this MongoDB process.

Request Query Parameters¶

The following query parameters are optional:

Name Type Necessity Description Default

pretty boolean Optional Flag indicating whether the response body should be in a prettyprint format. false

envelope

boolean

Optional

Flag that indicates whether or not to wrap the response in an envelope.

Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query.

For endpoints that return one result, the response body includes:

Name	Description
status	HTTP response code
envelope	Expected response body

false

Request Body Parameters¶

`Name`	Type	Necessity	Description
`alertsEnabled`	boolean	Optional	Set to `true` if alerts should be enabled for this MongoDB process.
`authMechanismName`	string	Optional	Specify which authentication mechanism should be used to connect to this MongoDB process. Possible values are: `MONGODB_CR` (This covers SCRAM-SHA-1, SCRAM-SHA-256, and MONGODB-CR.) `GSSAPI` `PLAIN` `MONGODB_X509` `NONE`
`hostname`	string	Required	Set the primary hostname Ops Manager should use to connect to this MongoDB instance.
`logsEnabled`	boolean	Optional	Set to `true` if Ops Manager should collect logs for this MongoDB process.
`password`	string	Optional	Password associated with `username` for connecting to this MongoDB process. Set this parameter if `"authMechanismName" : "MONGODB_CR"` Ops Manager doesn’t include this parameter in any Host \|\| response.
`port`	number	Required	Port on which MongoDB process listens.
`profilerEnabled`	boolean	Optional	Flag indicating whether Ops Manager collects profile information from this MongoDB process.
`sslEnabled`	boolean	Conditional	Flag indicating whether TLS should be enabled for this MongoDB process. Set to `true` if `"authMechanismName" : "MONGODB_X509"`.
`username`	string	Conditional	Username needed to connect to this MongoDB process. Required if `"authMechanismName" : "MONGODB_CR"`

Response¶

Name	Type	Description
`aliases`	array of strings	Array of alternate hostname and port combinations that Ops Manager discovered for the MongoDB process. These combinations can include hostnames, FQDNs, IPv4 addresses, and IPv6 addresses.
`alertsEnabled`	boolean	`true` if this MongoDB process has alerts enabled.
`authMechanismName`	string	Authentication mechanism used to connect to this MongoDB process. This displays only one of the following values: `MONGODB_CR` (This covers SCRAM-SHA-1, SCRAM-SHA-256, and MONGODB-CR.) `GSSAPI` `PLAIN` `MONGODB_X509` `NONE`
`clusterId`	string	Unique identifier of the cluster to which the MongoDB process belongs.
`created`	date	Date Ops Manager created or first discovered this MongoDB process.
`groupId`	string	Unique identifier of the group that owns this host.
`hasStartupWarnings`	boolean	`true` if this MongoDB process had startup warnings.
`hidden`	boolean	`true` if host is displayed in the Ops Manager UI. Hosts set to `true` are omitted from API responses.
`hiddenSecondary`	boolean	`true` if this host is a hidden secondary.
`hostEnabled`	boolean	`true` if the MongoDB process currently enabled.
`hostname`	string	Primary hostname as Ops Manager can best determine. This can be a hostname, an FQDN, an IPv4 address, or an IPv6 address.
`id`	string	Unique identifier.
`ipAddress`	string	IPv4 or IPv6 address associated with the `hostname` of this MongoDB process. Additional accessible IPv4 or IPv6 addresses may be displayed in the `aliases` array.
`journalingEnabled`	boolean	`true` if journaling is enabled for this MongoDB process.
`lastDataSizeBytes`	number	Uncompressed size of the host’s databases on disk in bytes excluding indexes. `lastDataSizeBytes` does not include the data in the local database.
`lastIndexSizeBytes`	number	Uncompressed size of the host’s database indexes on disk in bytes. This number does not include the size of the index for the local database.
`lastPing`	date	Timestamp in ISO 8601 date and time format in UTC when the last ping for this MongoDB process was received.
`lastRestart`	date	Timestamp in ISO 8601 date and time format in UTC when this process last restarted. If the MongoDB process has never been restarted, the `lastRestart` field is omitted.
`links`	array	Array that includes one or more links to sub-resources and/or related resources. The relations between URLs are explained in the Web Linking Specification. At minimum, a `links` array contains one link called `self`.
`logsEnabled`	boolean	`true` if Ops Manager is collecting logs for this MongoDB process.
`lowUlimit`	boolean	`true` if this MongoDB process’s host has a low `ulimit` setting.
`port`	number	Port on which the MongoDB process listens.
`profilerEnabled`	boolean	`true` if Ops Manager collects profile information from this MongoDB process.
`replicaSetName`	string	Name of the replica set this process belongs to. Only present if this process is part of a replica set.
`replicaStateName`	string	Current state of this MongoDB process within a replica set. Only present if this process is part of a replica set. See Replica Set Member States for possible values.
`shardName`	string	Name of the shard to which this process belongs. Only present if the process is part of a sharded cluster.
`slaveDelaySec`	number	Number of seconds this replica set member’s data trails the primary. If this value is set to `0`, the member is not configured as a delayed member. For additional details on slave delays, see Delayed Replica Set Members
`sslEnabled`	boolean	`true` if TLS/SSL and is enabled for this MongoDB process.
`systemInfo`	object	Object that contains RAM and CPU information for this MongoDB process’ server as reported by the operating system or container.
`systemInfo` `.memSizeMB`	number	Amount of RAM in megabytes.
`systemInfo` `.numCores`	number	Number of CPU cores.
`typeName`	string	Type for this MongoDB process. Possible values are: `STANDALONE` `REPLICA_PRIMARY` `REPLICA_SECONDARY` `REPLICA_ARBITER` `RECOVERING` `MASTER` `SLAVE` `SHARD_MONGOS` `SHARD_CONFIG` `SHARD_STANDALONE` `SHARD_PRIMARY` `SHARD_SECONDARY` `NO_DATA` The type for new hosts added to Ops Manager will be `NO_DATA` until the Monitoring receives its first ping.
`uptimeMsec`	number	Number of milliseconds since this process last restarted.
`version`	string	Version of MongoDB running for this process.
