Automation Configuration

Overview

The Automation Agent 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 Agent 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.

Configuration Version

This lists the version of the automation configuration.

"version" : <integer>
Name Type Description
version integer The version of the configuration.

Download Base

The download base is the path to the directory where automatic version downloads will be targeted and scripts for starting processes will be created.

"options" : {
    "downloadBase" : <string>,
    "downloadBaseWindows" : <string>
}
Name Type Description
options object The options object is required and must contain both the downloadBase and downloadBaseWindows fields.
options.downloadBase string The directory on Linux and Unix (including Mac OS X) platforms for automatic version downloads and startup scripts.
options.downloadBaseWindows string The directory on Windows platforms for automatic version downloads and startup scripts.

processes.name string A unique name to identify the instance.
processes.processType string Either mongod or mongos.
processes.version string The name of the mongoDbVersions specification used with this instance.
processes.<args> object This field is named either args2_6, for MongoDB versions 2.6 and higher (including 3.0 and higher), or args2_4, for versions 2.4 and earlier. The field contains a MongoDB configuration object in the format appropriate to the version. For information on format and supported MongoDB options, see supported configuration options.
processes.disabled Boolean Optional. Set to true to shut down the process.
processes.manualMode Boolean Optional. Set to true to operate this process in manual mode. The Automation Agent will take no actions on the process.
processes.hostname string The name of the host this process should run on. This defaults to localhost.
processes.authSchemaVersion integer The 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. The possible values are 3 and 5. The default is 5 for MongodDB 3.x clusters and 3 for MongoDB 2.6 clusters. See Upgrade to SCRAM-SHA-1 in the MongoDB 3.0 release notes for more information.
processes.featureCompatibilityVersion string Enables MongoDB 3.4 features that are not backwards compatible with MongDB 3.2. Valid values are “3.2” and “3.4”. New deployments of MongoDB 3.4 automatically set the value of this field to “3.4”. However, upgrading a host from 3.2 to 3.4 does not automatically add the field with a value of 3.4. See the setFeatureCompatibilityVersion reference for more information about behavior and affected features.
processes.cluster string Optional. Required for a mongos. The name of the cluster. This must correspond to the sharding.name field in the sharding array for the mongos.
processes.numCores integer Optional. The number of cores the process should be bound to. The Automation Agent will spread processes out across the cores as evenly as possible.
processes.logRotate object Optional. Enables log rotation for the MongoDB logs for a process.
processes.logRotate.sizeThresholdMB number The maximum size in MB for an individual log file before rotation. The file rotates immediately if the file meets either this sizeThresholdMB or the processes.logRotate.timeThresholdHrs limit.
processes.logRotate.timeThresholdHrs integer

The maximum time in hours for an individual log file before the next rotation. The time is since the last rotation.

The log file rotates immediately if the file meets either this timeThresholdHrs or the processes.logRotate.sizeThresholdMB limit.

processes.logRotate.numUncompressed integer Optional. The maximum number of total log files to leave uncompressed, including the current log file. The default is 5.
processes.logRotate.percentOfDiskspace number

Optional. The maximum percentage of total disk space that can be used to store the log files. If this limit is exceeded, the compressed log files are deleted to meet this limit, starting with the oldest log files first.

The default is .02.

processes.alias string Optional. A hostname alias (often a DNS CNAME) for the server on which the process runs. If an alias is specified, the Automation Agent prefers the alias over the host specified in processes.hostname when connecting to the server. You can also specify this alias in replicaSets.host and sharding.configServer.
processes.backupRestoreUrl string Optional. This is used only when creating a restore and specifies the delivery url for the restore. See Automate Backup Restoration through the API.

Replica Sets

The replicaSets array defines each replica set’s configuration. This field is required for deployments with replica sets.

"replicaSets" : [
    {
        "_id" : <string>,

        }
    },
    ...
]
Name Type Description
replicaSets array of objects Optional. Objects that define the configuration of each replica set. The Automation Agent uses the values in this array to create valid replica set configuration documents. The agent regularly checks that replica sets are configured correctly. If a problem occurs, the agent reconfigures the replica set according to its configuration document. The array can contain the following top-level fields from a replica set configuration document: _id; version; and members. For more information on the configuration documents, see replSetGetConfig in the MongoDB manual.
replicaSets._id string The name of the replica set.
replicaSets.version integer The version of the replica set configuration.
replicaSets.members array of objects Objects that define each member of the replica set. The members.host field must specify the host’s name as listed in processes.name. The Automation Agent expands the host field to create a valid replica set configuration. For more information on members objects, see replSetGetConfig in the MongoDB manual.
replicaSets.force object Optional. An object that contains the currentVersion field set to a version number. Automation will force a reconfiguration of the replica set if and only if the value of currentVersion equals the current version of the replica set. You can use force to reconfigure a replica set that has lost members and can’t reach a majority of votes.

        "configServerReplicaSet" : <string>,
        // "configServerReplicaSet" applies if the config server is a replica set.
        // For legacy mirrored config servers, use "configServer", which takes a
        // string array.
        "collections" : [
            {
                "_id" : <string>,

                "tag" : <string>
            },
            ...
        ]
    },
    ...
]
Name Type 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 Automation 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 If true, Ops Manager Automation manages all sharded collections and tags (i.e., zones) in the deployment.
sharding.name string The name of the cluster. This must correspond with the value in processes.cluster for a mongos.
sharding.configServerReplica string

The name of the config server’s replica set.

Use this field only for a config server that is a replica set. If you use legacy mirrored config servers (config servers that are not a replica set), use sharding.configServer.

sharding.configServer array of strings

For legacy mirrored config servers, an array that contains the names of the config server hosts. The host names are the same names used in each host’s processes.name field.

Use this field only for legacy mirrored config servers (config servers that are not a replica set), which are available only with MongoDB 3.2 and earlier. Otherwise use sharding.configServerReplica.

Important

MongoDB 3.4 removes support for mirrored config servers.

Optional. If the index uses collation (available beginning with MongoDB 3.4), this specifies the language-specific rules to use when sorting and matching strings.

If you specify the indexConfigs.collation object, you must specify the indexConfigs.collation.locale field. All other fields are optional.

If you do not specify the indexConfigs.collation object, the index will not include collation.

indexConfigs.collation.locale string The ICU locale. For a list of supported locales, see Collation Locales and Default Parameters in the MongoDB manual. To specify simple binary comparison, specify a value of simple.
indexConfigs.collation.caseLevel boolean Optional. If set to true, the index uses case comparison. This field applies only if the strength level is set to 1 or 2. See Collation in the MongoDB manual for details.
indexConfigs.collation.caseFirst string Optional. Determines the sort order of case differences during tertiary level comparisons. For possible values, see Collation in the MongoDB manual.
indexConfigs.collation.strength number Optional. The level of comparison to perform. Corresponds to ICU Comparison Levels. For possible values, see Collation in the MongoDB manual.
indexConfigs.collation.numericOrdering boolean

Optional. If set to true, collation compares numeric strings as numbers; i.e. 10 is greater than 2. If false, collation compares numeric strings as strings; i.e. 10 is less than 2.

The default is false. See Collation in the MongoDB manual for more information.

indexConfigs.collation.alternate string Optional. Determines whether collation should consider whitespace and punctuation as base characters during comparisons. For possible values, see Collation in the MongoDB manual.
indexConfigs.collation.maxVariable string Optional. Determines which characters are are considered ignorable. This field applies only if indexConfigs.collation.alternate is set to shifted. For possible values, see Collation in the MongoDB manual.
indexConfigs.collation.normalization boolean

Optional. If true, collation checks if text requires normalization and performs normalization to compare text.

The default is false. See Collation in the MongoDB manual for more information.

indexConfigs.collation.backwards boolean

Optional. If true, strings with diacritics sort from the back to the front of the string.

The default is false. See Collation in the MongoDB manual for more information.

indexConfigs.options document The index options. Currently supports only those options supported by the mgo driver.
