  • Ops Manager Configuration Settings

Ops Manager Configuration Settings

Ops Manager stores configuration settings both globally in the Ops Manager Application Database and locally on each server. Global settings apply to all your Ops Manager servers. Local settings apply to the server on which they are configured. Any local settings on a server override the global settings.

You configure local settings through a server’s conf-mms.properties file. Each server’s conf-mms.properties must contain the connection string and authentication settings for accessing the Ops Manager Application Database. The conf-mms.properties file also contains any overrides of global settings specific to that server.

The location of the conf-mms.properties file depends on how you installed Ops Manager, as described in the table below.

Install method conf-mms.properties location
rpm or deb package /opt/mongodb/mms/conf/
tar.gz archive <install-directory>/conf/
msi file (Windows)

<install-folder>\Server\Config

By default, this is: C:\MMSData\Server\Config.

Bypass Initial Configuration via the User Interface

If you would like to skip the initial setup wizard after creating the first account and either edit the conf-mms.properties file or use the API to configure Ops Manager, change the following settings. This setting can help if you are automating the deployment of Ops Manager instances.

mms.ignoreInitialUiSetup

Type: boolean

Set this to true to allow full use of Ops Manager without requiring the first user account to complete the initial setup wizard.

Warning

Ops Manager performs its regular pre-flight check to verify that it has all of the required settings. If one or more of those settings are not included in conf-mms.properties, Ops Manager refuses to start and lists which fields are missing in the log file.

Before starting Ops Manager, add the following required settings to conf-mms.properties to enable basic Ops Manager functionality:

UI Setting conf-mms.properties Setting Required
URL to Access Ops Manager mms.centralUrl Required
None mongo.mongoUri Required
Client Certificate Mode mms.https.ClientCertificateMode Required
"From" Email Address mms.fromEmailAddr Required
"Reply To" Email Address mms.replyToEmailAddr Required
Admin Email Address mms.adminEmailAddr Required
Email Delivery Method Configuration mms.emailDaoClass Required
Transport mms.mail.transport Required
SMTP Server Hostname mms.mail.hostname Required
SMTP Server Port mms.mail.port Required
User Authentication Method mms.userSvcClass Optional
Snapshot Interval brs.snapshotSchedule.interval Optional
Base Retention of Snapshots brs.snapshotSchedule.retention.base Optional
Daily Retention of Snapshots brs.snapshotSchedule.retention.daily Optional
Weekly Retention of Snapshots brs.snapshotSchedule.retention.weekly Optional
Monthly Retention of Snapshots brs.snapshotSchedule.retention.monthly Optional
Versions Directory automation.versions.directory Optional

Note

Fields marked as Optional have default values. If you want to change them, you can provide the setting and a new value.

Example

The following values are examples. Substitute values appropriate to your Ops Manager installation. You may add any of the other settings specified in this reference.

To configure an Ops Manager installation with the minimum functionality, add the following settings to conf-mms.properties:

mms.ignoreInitialUiSetup=true
mongo.mongoUri=mongodb://db1.example.com:27017,db2.example.com:27017,db3.example.com:27017
mms.centralUrl=http://localhost:8080
mms.fromEmailAddr=example@example.com
mms.replyToEmailAddr=example@example.com
mms.adminEmailAddr=example@example.com
mms.mail.transport=smtps
mms.mail.hostname=mail.example.com
mms.mail.port=465

All Clusters View

mms.allclusters.onlyMembership

Type: boolean

Default: False

Determines whether the View All Clusters displays only the deployments to which an Ops Manager administrator belongs (set the value to true) or the deployments to which the administrator has access (set the value to false).

Application Database Connection Settings

The following settings configure the Ops Manager connection to the Ops Manager Application Database. You must configure this setting in the conf-mms.properties file on each Ops Manager server. To encrypt authentication information, see Encrypt User Credentials.

mongo.mongoUri

Type: string

connection string used to access the Ops Manager Application Database. The connection string must include the following if applicable:

  • All members of the replica set, if the Ops Manager Application database is a replica set.
  • Authentication credentials for the authentication mechanism used on the Ops Manager Application database.

See the following example connection strings:

Replica Sets

If you use a replica set for the database’s backing instance, specify all members of the replica set, as shown in the following example. If you omit the port number, Ops Manager uses the default 27017 port for all hosts.

mongo.mongoUri=mongodb://db1.example.com:40000,db2.example.com:40000,db3.example.com:40000

Note

Ops Manager does not require the replicaSet option in the URI.

Default MongoDB Authentication

For a MongoDB instance using the MongoDB SCRAM-SHA-1 or MONGODB-CR challenge-response mechanisms, the connection string must include authentication credentials. The Ops Manager Application must authenticate as a MongoDB user with the following roles:

Prefix the hostname with the MongoDB username and password in the form <username>:<password>@

mongo.mongoUri=mongodb://mongodbuser1:password@mydb1.example.com:40000
x.509 Certificate Authentication

For a MongoDB instance using MONGODB-X509 authentication, you must first add the value of the subject from the client certificate as a MongoDB user, as described in Use x.509 Certificates to Authenticate Clients in the MongoDB manual. The client certificate is contained in the PEM file you specify in the mongodb.ssl.PEMKeyFile setting. Once you have created the user, prefix the host specified in mongo.mongoUri with the name of the new user and append authMechanism=MONGODB-X509 after the specified port:

mongo.mongoUri=mongodb://<new_mongodb_user>@mydb1.example.com:40000/?authMechanism=MONGODB-X509
LDAP Authentication

For a MongoDB instance using LDAP, prefix the hostname with the MongoDB username and password in the form <username>:<password>@, and append the authMechanism=PLAIN&authSource=$external options after the port:

mongo.mongoUri=mongodb://mongodbuser1:password@mydb1.example.com:40000/?authMechanism=PLAIN&authSource=$external
Kerberos Authentication

For a MongoDB instance using Kerberos, prefix the hostname with the Kerberos user principal and specify the authentication mechanism, authMechanism=GSSAPI, after the port.

Kerberos user principal names have the form <username>@<KERBEROS REALM>. You must escape the user principal, replacing symbols with the URL encoded representation. A Kerberos user principal of username@REALM.EXAMPLE.COM would therefore become username%40REALM.EXAMPLE.COM.

mongo.mongoUri=mongodb://username%40REALM.EXAMPLE.COM@mydb1.example.com:40000/?authMechanism=GSSAPI

To enable Kerberos authentication between the Ops Manager Application and the Snapshot Storage, review the following settings:

See also

authMechanism and authSource in the MongoDB manual.

mongo.encryptedCredentials

Type: boolean

To use encrypted credentials in mongo.mongoUri, encrypt the credentials using the Ops Manager credentialstool, enter them in the mongo.mongoUri setting, and set this to true:

Type: string

Required if using Kerberos. This is the default realm for Kerberos. It is being used for JVM’s java.security.krb5.realm.

jvm.java.security.krb5.realm=EXAMPLE.COM

TLS/SSL Connection to the Application Database

mongo.ssl

Type: boolean

Enables TLS/SSL connection to the Ops Manager Application Database when set to true.

mongodb.ssl.CAFile

Type: string

Name of the PEM file that contains the root certificate chain from the Certificate Authority that signed the MongoDB server certificate.

mongodb.ssl.PEMKeyFile

Type: string

Name of the PEM file that contains the X509 certificate and private key. Required if the MongoDB instance is running with the --sslCAFile option or net.ssl.CAFile setting.

If you authenticate using the MONGODB-X509 authentication mechanism, you also enter this as the name of the user in the mongoUri connection string.

Backup

mms.alerts.BackupAgentConfCallFailure.maximumFailedConfCalls

Type: integer

Default: 10

If the Backup Agent experiences more than this number of consecutive failed conf calls, Ops Manager triggers the following global alert: Backup Agent has too many conf call failures

mms.alerts.OutsideSpaceUsedThreshold.maximumSpaceUsedPercent

Type: integer

Default: 85

If the blockstore uses at least this percentage of its total disk capacity, Ops Manager triggers the following system alert: Blockstore space used exceeds threshold.

Type: string

FQDN of the Ops Manager host to which the Monitoring Agents use to push data.

Uses the value of mms.centralUrl if not set.

Monitoring Agent Session Failover

Beginning with Monitoring Agent version 5.0.0, Ops Manager can distribute monitoring assignments among up to 100 running Monitoring Agents. One agent is the primary agent and the others share in monitoring responsibilities. If an agent fails, Ops Manager redistributes that agent’s monitoring assignments. If you run more than 100 Monitoring Agents, the additional agents run as standby agents that are completely idle, except to log their status as standby agents and to periodically ask Ops Manager whether they should receive monitoring assignments.

Note

Also beginning with version 5.0.0, the Monitoring Agent stores monitoring metrics at 10-second granularity.

Prior to Monitoring Agent 5.0.0, only the primary Monitoring Agent handles monitoring assignments. All additional running agents are standby agents.

The following settings tune the interval Ops Manager uses to determine if a Monitoring Agent is unaccessible and the frequency with which standby agents poll Ops Manager to determine if they should receive monitoring assignments.

mms.monitoring.agent.session.timeoutMillis

Type: integer

Default: 90000

Interval that Ops Manager uses to determine if a standby agent should start monitoring. If Ops Manager does not hear from a Monitoring Agent for the duration specified, Ops Manager promotes a standby agent. Configuring the timeout below 90000 (90 seconds) will cause Ops Manager to fail at startup with a configuration error.

mms.monitoring.agent.standbyCollectionFactor

Type: integer

Default: 4

Specifies how frequently a standby agent checks in with Ops Manager to see if it should start monitoring. The following values are permitted:

Value Standby Agents Check Frequency
1 Every 55 seconds
2 Every 27 seconds
3 Every 18 seconds
4 Every 14 seconds

Public API

mms.publicApi.whitelistEnabled

Type: boolean

Certain API calls require that requests originate from a whitelisted IP address. To turn off this requirement, add this setting and set its value to false.

Security Settings

mms.security.disableBrowserCaching

Type: boolean

Default: False

When true, Ops Manager makes all HTTP responses not cacheable.

mms.security.hstsMaxAgeSeconds

Type: integer

Default: 0 (Can use HTTP or HTTPS.)

How long (in seconds) Ops Manager limits browser connections to use HTTPS. This value must be a positive integer. A value of 0 means that it can use HTTP or HTTPS.

To learn how to deploy HSTS, see HTTP Strict Transport Security, RFC 6797 and hstspreload.org.

SNMP Heartbeat Settings

Ops Manager uses SNMP v2c. You can configure the Ops Manager Application to send a periodic heartbeat trap notification (v2c) that contains an internal health assessment of the Ops Manager Application. The Ops Manager Application can send traps to one or more endpoints on the standard SNMP UDP port 162.

To configure the Ops Manager Application to send trap notifications, first download the Management Information Base (MIB) file at http://downloads.mongodb.com/on-prem-monitoring/MMS-MONGODB-MIB.txt . Then add the following settings as custom settings. To do so, click the Admin link, then the General tab, then the Ops Manager Config page, and then the Custom section.

snmp.community

Type: string

Default: public

Snmp community for SNMP traps sent by Ops Manager.

snmp.default.heartbeat.interval

Type: number

Default: 300

Number of seconds between heartbeat notifications.

snmp.default.hosts

Type: string

Default: blank

Comma-separated list of hosts where ‘heartbeat’ traps will be sent on the standard UDP port 162. You must set snmp.default.hosts to enable the SNMP heartbeat functionality; otherwise, leaving the setting blank disables the SNMP heartbeat functionality.

snmp.listen.port

Type: number

Default: 11611

Listening UDP port for SNMP. Setting to a number less than 1024 will require running the Ops Manager Application with root privileges.

Non-Uniform Memory Access (NUMA) Settings

mongodb.disable.numa

Type: boolean

To disable NUMA for the head databases:

  1. Click the Admin link.
  2. Click the General tab.
  3. Click the Ops Manager Config page.
  4. Click the Custom section.
  5. Add mongodb.disable.numa as a Key and set its Value to true.
  6. Click Save.

See MongoDB and NUMA Hardware in the MongoDB Production Notes to learn more about NUMA.

Important
