Advanced Options for MongoDB Deployments

The following mongod and mongos configuration options are available through the Ops Manager Advanced Configuration Options field when you deploy MongoDB. You select advanced options when deploying:

The Ops Manager Advanced Configuration Options map to the MongoDB configuration options and parameters described as follows.

Limited to Listed Options

If a MongoDB option isn’t listed on this page, you may use setParameter to add the setting. Settings added in this way apply to MongoDB instances that Ops Manager manages when those instances start up.


To edit Advanced Options, complete the following steps.


Click MODIFY next to the deployment that you wish to edit.


Scroll to Advanced Configuration Options and click Add Option.


Select the desired option and click Add.

Audit Log

Ops Manager Interface MongoDB Option
auditEncryptionKeyIdentifier auditLog.auditEncryptionKeyIdentifier
compressionMode auditLog.compressionMode
auditDestination auditLog.destination
auditFilter auditLog.filter
auditFormat auditLog.format
localAuditKeyFile auditLog.localAuditKeyFile
auditPath auditLog.path

You can add these audit log parameters with a setParameter option in the Advanced Configuration Options section. To learn more, see the step about setting these parameters in the Deploy a Replica Set procedure.

To encrypt the audit log, before you start MongoDB instances that Ops Manager manages, add the auditEncryptKeyWithKMIPGet and auditEncryptionHeaderMetadataFile parameters in the Advanced Configuration Options section.

Set Parameter


Ops Manager does not check to see if the parameters you provide are valid. Check the MongoDB Server Manual for accepted parameters and values.

Ops Manager Interface MongoDB Option

You can add any value from Server Parameters as a setParameter.

For supported MongoDB versions and MongoDB Agent versions, you can set certain setParameter parameters without a rolling restart. To determine whether you can set a setParameter parameter during runtime or upon startup, retrieve details on that parameter. For complex setParameter parameters, you must set the parameter values in the same format as in the process configuration file or in the --setParameter command line option.


If you set the watchdogPeriodSeconds parameter, MongoDB Agent triggers a rolling restart.

If you delete or remove a parameter, MongoDB Agent keeps the parameter’s current value until you make another change to that parameter. To reset the parameter to its default value, you must manually set the value or trigger a rolling restart.

If you attempt to set a parameter that MongoDB Agent can’t set at startup, MongoDB Agent triggers a rolling restart and fails to start up a mongod instance.
