Description
Considerations for Upgrade
- Direct upgrades are supported only from 1.3 and 1.4.
- Change in configurations and policy for 2FA
- Two-factor authentication must now be explicitly enabled using the mms.multiFactorAuth.require setting. See [LINK TO DOCS]
- The default LDAP group separator was changed from , to ;; . See [LINK TO DOCS]
- Suppressed hosts will only remain suppressed for 30 minutes
- Previously, if a host was deleted from MMS Monitoring the hostname/port would be added to a suppression list with an infinite lifetime. This was meant to prevent a race condition in which a host in a cluster would be auto-discovered by another member of a cluster before the cluster could fully be removed.
- Suppressed hosts are now kept on this list for only 30 minutes.
- mms.remoteIp.header in conf-mms.properties should be set if MMS is behind a load balancer
- mongo.backupdb.mongoUri is no longer in conf-mms.properties. This was previously a required field in this file. It is still in the backup daemons's conf-daemon.properties.
- Stored MongoDB profile data is not transferred between OnPrem 1.4 and OnPrem 1.5
- If the optional feature to collect and store MongoDB profile data in MMS was enabled, this data will not be transferred between OnPrem 1.4 and OnPrem 1.5.
Improvements
- When an MMS Backup job fails to bind, the system will periodically and automatically retry
- All MMS Backup jobs will retry indefinitely
- Point in Time restores can be selected with one second granularity
New Features
- Public API http://mms.mongodb.com/help/reference/api/ currently, need to be visible on help-hosted

- MMS can authenticate using LDAP to both the database backing MMS and the databases being monitored/backed up [LINK TO DOCS]

- Ability to acknowledge alerts
- New cluster page - shows individual, sum or average metrics for all shards in a cluster
