MMS Server Changelog

On-Prem MongoDB Management Service Server 1.5.5

Released 2015-03-26

  • Security Update: resolved an issue where users removed from LDAP groups were not always removed from corresponding Ops Manager groups. This upgrade is highly recommended for anyone using LDAP authentication.

On-Prem MongoDB Management Service Server 1.5.4

Released 2015-03-18

  • Fixed race condition that could cause the Backup Daemon to hang when the MongoDB process for a HEAD DB fails to start.
  • Fixed issue where a rollback occurring shortly after a terminate could step on the terminate.
  • The time before an unreachable mongos process is deactivated is now configurable on a per group basis. See Admin Only Group Settings.
  • The time before a standby Monitoring Agent takes over after the primary Monitoring Agent stops responding is now configurable to a minimum of 90 seconds. See the mms.monitoring.agent.session.timeoutMillis setting in Configuration.
  • For Backup HTTP pull restore, the link expiration and the number of allowed uses of a link are now configurable. See Advanced Backup Restore Settings.

On-Prem MongoDB Management Service Server 1.5.3

Released 2014-12-17

Significant improvements in performance for the processing of MMS Monitoring data for MMS Groups with a large number of hosts

On-Prem MongoDB Management Service Server 1.5.2

Released 2014-11-18

  • Added Support for archive restores (.tar.gz) for databases whose filenames exceed 100 characters.
  • API: Skip missed points in metrics data, instead of returning empty data.
  • API: Return correct number of data points when querying metric data with the period option.
  • Backup Agent update to 2.3.3.209-1

On-Prem MongoDB Management Service Server 1.5.1

Released 2014-09-26

  • Fix cases where replica set member alerts (e.g. no primary, number of healthy members) could send false positives.
  • Skip backup-daemon rootDirectory and mongo.backupdb.mongoUri overlap check when the mongo.backupdb.mongoUri is on a different host.
  • mms-gen-key script handles user’s effective group being different then the username.
  • Security enhancements.

On-Prem MongoDB Management Service Server 1.5.0

Released 2014-09-02

Considerations for Upgrade

  • MMS only supports direct upgrades 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.

  • The default LDAP group separator became ;;. Previously the separator was ,. See the LDAP configuration documentation for more information.

  • Suppressed hosts will only remain suppressed for 30 minutes.

    Previously, if after deleting a host, from MMS Monitoring the hostname and port combination would be added to a suppression list with an infinite lifetime. The suppression list prevented a race condition where host in a cluster would be auto-discovered by another member of a deployment before the host could was fully removed. Now, hostname and port combinations remain on the suppression list for only 30 minutes.

  • Set the mms.remoteIp.header in the conf-mms.properties file if clients access the MMS Application via a load balancer.

  • mongo.backupdb.mongoUri is no longer in conf-mms.properties. This was previously a required field in this file. It remains in the backup daemons’s conf-daemon.properties.

  • Stored MongoDB profile data is not transferred between OnPrem 1.4 and OnPrem 1.5 during the upgrade process.

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 are now available with one second granularity.

New Features

  • MMS Public API.
  • Explicit support for multiple MMS Backup Blockstore Databases and the ability to pin MMS Groups to specific backup daemons and databases. See Configure Multiple Blockstores in Multiple Data Centers for more information.
  • MMS can authenticate using LDAP to both the database backing MMS and the monitored and backed up MongoDB deployments. See LDAP.
  • Enhanced auditing. See Audit Events for more information.
  • Ability to acknowledge alerts.
  • New cluster page that shows individual, sum or average metrics for all shards in a cluster.

On-Prem MongoDB Management Service Server 1.4.3

Released 2014-07-22

  • Addressed issues related to Backup Job assignment for 2.6.x clusters that used the clusterMonitor role to support MMS Monitoring.
  • Fixed problem importing email addresses for users for deployments that use LDAP integration.
  • Fixed rare race condition caused high CPU usage in the MMS HTTP Service if the application cannot connect to one of the backing databases.
  • Additional security enhancements.

On-Prem MongoDB Management Service Server 1.4.2

Released 2014-05-29

  • Critical bug fix for backing up MongoDB 2.6 deployments that include user or custom role definitions:

    • The system.version collection in the admin database will be included in all future snapshots.
    • The system.roles collection in the admin database will be included after a new initial sync is performed.

    Users capturing backups of MongoDB 2.6 replica sets or clusters with MMS that include custom role definitions should perform a new initial sync. Taking a new initial sync will ensure that the role definitions are included in the backup.

  • Disable MongoDB usePowerOf2Sizes for insert-only MMS Backup collections.

  • Speed optimization for MMS Backup HTTP pull restores.

  • Fix for LDAP integration, MMS now passes full dn correctly when authenticating the user.

On-Prem MongoDB Management Service Server 1.4.1

Released 2014-04-28

  • Ability to Backup replica sets or clusters using Kerberos authentication
  • Ability to Backup replica sets or clusters running specific custom MongoDB builds provided by MongoDB, Inc.
  • Fix validation issue preventing Backup of MongoDB 2.6.0 clusters
  • Reduced log noise from Monitoring Agent when monitoring MongoDB 2.0 or unreachable mongods

On-Prem MongoDB Management Service Server 1.4.0

Released 2014-04-08

  • Includes MMS Backup: continuous backup with point-in-time recovery of replica sets and cluster-wide snapshots of sharded clusters.
  • Finer-grained roles and permissions.
  • Improved user interface for alerts.
  • Enhanced Activity Feed for auditing of all activity.
  • Monitoring Agent distributed as OS-specific binary. Python dependency removed.
  • LDAP integration for managing users and groups.
