Overview

The Automation uses an automation configuration to determine the desired state of a MongoDB deployment and to effect changes as needed. If you modify the deployment through the Ops Manager web interface, you never need manipulate this configuration.

If you are using the Automation without Ops Manager, you can construct and distribute the configuration manually.

Optional fields are marked as such.

A field that takes a <number> as its value can take integers and floating point numbers.

Note

Ops Manager doesn't support configuration and management of the MongoDB server net.unixDomainSocket options such as net.unixDomainSocket.enabled, net.unixDomainSocket.pathPrefix, and net.unixDomainSocket.filePermissions using the Ops Manager automation configuration.

Ops Manager automation doesn't validate the following MongoDB settings. If you provide an incorrect value, it could result in issues, downtime, or both:

Configuration Version

This lists the version of the automation configuration.

"version" : "<integer>"

Name	Type	Necessity	Description
version	integer	Required	Revision of this automation configuration file.

Download Base

Ops Manager downloads automatic versions and runs starting scripts in the directory set in options.downloadBase.

"options" : {
  "downloadBase" : "<string>",
}

Name	Type	Necessity	Description
options	object	Required	Path for automatic downloads of new versions.
options.downloadBase	string	Required	Directory on Linux and UNIX platforms for automatic version downloads and startup scripts.

MongoDB Versions Specifications

36 }]

Name	Type	Necessity	Description
processes	array	Required	Contains objects that define the `mongos` and `mongod` instances that Ops Manager monitors. Each object defines a different instance.
processes[n].args2_6	object	Required	MongoDB configuration object for MongoDB versions 2.6 and later. The `processes.args2_6` object accepts most MongoDB settings and parameters for MongoDB versions 2.6 and later. To learn more, see MongoDB Settings and Automation Support.
processes[n].alias	string	Optional	Hostname alias (often a DNS CNAME) for the host on which the process runs. If an alias is specified, the MongoDB Agent prefers this alias over the hostname specified in processes.hostname when connecting to the host. You can also specify this alias in replicaSets.host and sharding.configServer.
processes[n].authSchemaVersion	integer	Required	Schema version of the user credentials for MongoDB database users. This should match all other elements of the processes array that belong to the same cluster. Ops Manager accepts 3 and 5 for this parameter. MongoDB 3.x and 4.x clusters default to 5. MongoDB 2.6 clusters default to 3. To learn more, see Upgrade to SCRAM-SHA-1 in the MongoDB 3.0 release notes.
processes[n].backupRestoreUrl	string	Optional	Delivery URL for the restore. Ops Manager sets this when creating a restore. To cancel an in-progress restore operation, set this option to `CANCEL`. To learn more, see Automate Backup Restoration through the API.
processes[n].cluster	string	Conditional	Name of the sharded cluster. Set this value to the same value in the sharding.name parameter in the sharding array for the `mongos`. Required for a `mongos`. Not needed for a `mongod`.
defaultRWConcern.defaultReadConcern.level	string	Optional	Consistency and isolation properties set for the data read from replica sets and replica set shards. MongoDB Atlas accepts the following values: "available" "local" "majority"
defaultRWConcern.defaultWriteConcern.j	boolean	Optional	Flag that indicates whether the write acknowledgement must be written to the on-disk journal.
defaultRWConcern.defaultWriteConcern.w	string	Optional	Desired number of mongod instances that must acknowledge a write operation in a replica sets and replica set shards. MongoDB Atlas accepts the following values: Any number 0 or greater "majority"
defaultRWConcern.defaultWriteConcern.wtimeout	number	Optional	Desired time limit for the write concern expressed in milliseconds. Set this value when you set defaultRWConcern.defaultWriteConcern.w to a value greater than 1.
processes[n].disabled	Boolean	Optional	Flag that indicates if this process should be shut down. Set to true to shut down the process.
processes[n].featureCompatibilityVersion	string	Required	Version of MongoDB with which this process has feature compatibility. Changing this value can enable or disable certain features that persist data incompatible with MongoDB versions earlier or later than the featureCompatibilityVersion you choose. Ops Manager accepts 5.0, 6.0, and 7.0 as parameter values. If you have an existing deployment, Ops Manager only accepts a featureCompatibilityVersion equal to or one release older than the MongoDB version you deployed. To learn which of these parameter values is supported for each MongoDB version, and which features each of these values enable or disable, see setFeatureCompatibilityVersion in the MongoDB Manual. Ops Manager sets this parameter to match the MongoDB version for new deployments. Ops Manager doesn't automatically increment this parameter when you upgrade a host from one MongoDB version to the next. To learn more, see setFeatureCompatibilityVersion.
processes[n].hostname	string	Required	Name of the host that serves this process. This defaults to localhost.
processes[n].lastCompact	string	Optional	Timestamp in ISO 8601 date and time format in UTC when Ops Manager last reclaimed free space on a cluster's disks. During certain operations, MongoDB might move or delete data but it doesn't free the currently unused space. Ops Manager reclaims the disk space in a rolling fashion across members of the replica set or shards. To reclaim this space: Immediately, set this value to the current time as an ISO 8601 timestamp. Later, set this value to a future ISO 8601 timestamp. Ops Manager reclaims the space after the current time passes the provided timestamp. To remove any ambiguity as to when you intend to reclaim the space on the cluster's disks, specify a time zone with your ISO 8601 timestamp. For example, to set processes.lastCompact to 28 January 2021 at 2:43:52 PM US Central Standard Time, use `"processes.lastCompact" : "2021-01-28T14:43:52-06:00"`
processes[n].lastRestart	string	Optional	Timestamp in ISO 8601 date and time format in UTC when Ops Manager last restarted this process. If you set this parameter to the current timestamp, Ops Manager forces a restart of this process after you upload this configuration. If you set this parameter for multiple processes in the same cluster, the Ops Manager restarts the selected processes in a rolling fashion across members of the replica set or shards.
processes[n].lastResync	string	Optional	Timestamp in ISO 8601 date and time format in UTC of the last initial sync process that Ops Manager performed on the node. To trigger the init sync process on the node immediately, set this value to the current time as an ISO 8601 timestamp. WARNING: Use this parameter with caution. During initial sync, Automation removes the entire contents of the node's `dbPath` directory. If you set this parameter: On the secondary node, the MongoDB Agent checks whether the specified timestamp is later than the time of the last resync, and if confirmed, starts init sync on this node. For example, to set `processes.lastResync` on the secondary node to 28 May 2021 at 2:43:52 PM US CentralStandard Time, use: `"processes.lastResync" : "2021-05-28T14:43:52-06:00"` If the MongoDB Agent confirms that this timestamp is later than the recorded time of the last resync, it starts init sync on the node. On the primary node, the MongoDB Agent waits until you ask the primary node to become the secondary with the `rs.stepDown()` method, and then starts init sync on this node. On all of the nodes in the same cluster, including the primary, the MongoDB Agent checks whether the specified timestamp is later than the time of the last resync, and if confirmed, starts init sync on the secondary nodes in a rolling fashion. The MongoDB Agent waits until you ask the primary node to become the secondary with the `rs.stepDown()` method, and then starts init sync on this node. To learn more, see Initial Sync.
processes[n].lastKmipMasterKeyRotation	string	Optional	Timestamp in ISO 8601 date and time format in UTC when Ops Manager last rotated the master KMIP key. If you set this parameter to the current timestamp, Ops Manager rotate the key after you upload this configuration.
processes[n].logRotate	object	Optional	MongoDB configuration object for rotating the MongoDB logs of a process.
processes[n].logRotate. numTotal	integer	Optional	Total number of log files that Ops Manager retains. If you don't set this value, the total number of log files defaults to 0. Ops Manager bases rotation on your other processes.logRotate settings.
processes[n].logRotate. numUncompressed	integer	Optional	Maximum number of total log files to leave uncompressed, including the current log file. The default is 5.
processes[n].logRotate. percentOfDiskspace	number	Optional	Maximum percentage of total disk space that Ops Manager can use to store the log files expressed as decimal. If this limit is exceeded, Ops Manager deletes compressed log files until it meets this limit. Ops Manager deletes the oldest log files first. The default is 0.02.
processes[n].logRotate. sizeThresholdMB	number	Required	Maximum size in MB for an individual log file before Ops Manager rotates it. Ops Manager rotates the log file immediately if it meets the value given in either this sizeThresholdMB or the processes.logRotate.timeThresholdHrs limit.
processes[n].logRotate. timeThresholdHrs	integer	Required	Maximum duration in hours for an individual log file before the next rotation. The time is since the last rotation. Ops Manager rotates the log file once the file meets either this timeThresholdHrs or the processes.logRotate.sizeThresholdMB limit.
processes[n].manualMode	Boolean	Optional	Flag that indicates if MongoDB Agent automates this process. This defaults to false. Set to true to disable Automation on this process. The MongoDB Agent takes no further actions on this process. Set to false to enable Automation on this process. The MongoDB Agent automates actions on this process.
processes[n].name	string	Required	Unique name to identify the instance.
processes[n].numCores	integer	Optional	Number of cores that Ops Manager should bind to this process. The MongoDB Agent distributes processes across the cores as evenly as possible.
processes[n].processType	string	Required	Type of MongoDB process being run. Ops Manager accepts `mongod` or `mongos` for this parameter.
processes[n].version	string	Required	Name of the mongoDbVersions specification used with this instance.

Name	Type	Necessity	Description
sharding	array of objects	Optional	Objects that define the configuration of each sharded cluster. Each object in the array contains the specifications for one cluster. The MongoDB Agent regularly checks each cluster's state against the specifications. If the specification and cluster don't match, the agent will change the configuration of the cluster, which might cause the balancer to migrate chunks.
sharding.managedSharding	boolean	Optional	Flag that indicates whether Ops Manager Automation manages all sharded collections and tags in the deployment. Starting in Ops Manager version 7.0, this can be set only to `false`.
sharding.name	string	Conditional	Name of the cluster. This must correspond with the value in processes.cluster for a `mongos`.
sharding.configServerReplica	string	Conditional	Name of the config server replica set. You can add this array parameter if your config server runs as a replica set. If you run legacy mirrored config servers that don't run as a replica set, use sharding.configServer.
sharding.configServer	array of strings	Conditional	Names of the config server hosts. The host names match the names used in each host's processes.name parameter. IMPORTANT: MongoDB 3.4 removes support for mirrored config servers. If your sharded cluster runs MongoDB 3.4 or later, use sharding.configServerReplica.
sharding.shards	array of objects	Conditional	Cluster's shards.
sharding.shards._id	string	Conditional	Name of the shard.
sharding.shards.rs	string	Conditional	Name of the shard's replica set. This is specified in the replicaSets._id parameter.
sharding.shards.tags	array of strings	Conditional	Zones assigned to this shard. You can add this array parameter if you use zoned sharding.

Required if you enable authentication and "auth.disabled" : false.

If you change the auth.key value, you must change the auth.keyfile value.

auth.keyfile

string

Conditional

Path and name of the key file that Ops Manager uses to authenticate to the MongoDB processes.

Required if you enable authentication and "auth.disabled" : false.

If you change the auth.keyfile value, you must change the auth.key value.

auth

.newAutoPwd

string

Optional

New password that the Automation uses when connecting to an instance. To rotate passwords without losing the connection:

Set auth.newAutoPwd and leave auth.autoPwd with its current password.
Wait for the goal state.
auth.newAutoPwd copies over the auth.autoPwd password automatically.

You can set this option only when you include SCRAM-SHA-1 or SCRAM-SHA-256 as one of the authentication mechanisms for the Automation in auth.autoAuthMechanisms.

auth.newKey

string

Optional

Contents of a new key file that you want Ops Manager to use to authenticate to the MongoDB processes.

When you set this option, Ops Manager rotates the key that the application uses to authenticate to the MongoDB processes in your deployment. When all MongoDB Agents use the new key, Ops Manager replaces the value of auth.key with the new key that you provided in auth.newKey and removes auth.newKey from the automation configuration.

auth.usersWanted[n].authenticationRestrictions

array of documents

Optional

Authentication restrictions that the host enforces on the user.

WARNING: If a user inherits multiple roles with incompatible authentications restrictions, that user becomes unusable. For example, if a user inherits one role in which the clientSource field is [198.51.100.0] and another role in which the clientSource field is [203.0.113.0], the server is unable to authenticate the user. For more information about authentication in MongoDB, see Authentication.

auth.usersWanted[n].authenticationRestrictions[k].clientSource

array of strings

Conditional

If present when authenticating a user, the host verifies that the given list contains the client's IP address CIDR range. If the client's IP address is not present, the host does not authenticate the user.

auth.usersWanted[n].authenticationRestrictions[k].serverAddress

array of strings

Conditional

Comma-separated array of IP addresses to which the client can connect. If present, the host verifies that Ops Manager accepted the client's connection from an IP address in the given array. If the connection was accepted from an unrecognized IP address, the host doesn't authenticate the user.

                     "<substition/ldapQuery>": "<DN-string/RFC4516-encoded-LDAP-query>"
             }
   ]
}

Name	Type	Necessity	Description
ldap	object	Optional	Object that contains the settings to enable and configure LDAP authorization.
ldap.servers	string	Conditional	Comma-separated string that contains one or more LDAP servers in `<host>:<port>` format to execute queries against. You can use `setParameter` to configure this setting on a running system. For LDAP authorization, you must specify this setting.
ldap.timeoutMS	long	Optional	Amount of time in milliseconds that MongoDB waits for an LDAP server to respond to a request before timing out. You can use `setParameter` to configure this setting on a running system. By default, MongoDB times out after ten seconds.
ldap.bindMethod	string	Optional	Human-readable string that indicates whether to use simple authentication or an SASL protocol to authenticate itself. You can specify `simple` or `sasl`. By default, MongoDB uses simple authentication.
ldap.bindSaslMechanisms	string	Optional	String that contains a comma-separated list of SASL mechanisms for MongoDB to attempt authentication against the LDAP server while binding. By default, MongoDB uses `DIGEST-MD5` to bind.
ldap.bindQueryUser	string	Conditional	LDAP entity domain name that MongoDB binds as when it connects to an LDAP server. You can use `setParameter` to configure this setting on a running system. For MongoDB to bind with authentication credentials, you must specify this setting.

ldap.userCacheInvalidationPeriod	integer	Optional	Interval that MongoDB waits between user cache flushes. When the external user cache is flushed, the next operation that an LDAP authorized user makes requires a reaquisition of roles. If you specify a high value, you might decrease the load on your LDAP servers and increase the amount of time needed to synchronize MongoDB roles with LDAP group membership. By default, MongoDB waits 30 seconds between cache flushes.
ldap.authzQueryTemplate	string	Conditional	RFC 4516 formatted URL of the LDAP query to execute to obtain LDAP groups relative to the `ldap.server` setting. In this URL, the placeholder token string `{USER}` is replaced with the acquired user domain name. You can use `setParameter` to configure this setting on a running system. For LDAP authorization, you must specify this setting.
ldap.userToDNMapping	array	Optional	JSON-formatted array that contains the ordered transformations that MongoDB applies to authenticate MongoDB user names to match their domain names. You can specify this setting if you use an alternate authentication method, or if the user name passed to MongoDB for authentication doesn't match the LDAP domain name. You can use `setParameter` to configure this setting on a running system. By default, MongoDB uses user names as the domain names for automatic LDAP authorization.
