Configure AWS Integration — MongoDB Cloud Manager

Configure AWS Integration¶

On this page

  • Considerations
  • Rolling Resync onto New EC2 Instances
  • Update a Replica Set’s Hostnames

Important

The ability to provision MongoDB servers in AWS using Cloud Manager was retired in October 2017.

  • Any existing clusters continue as they are.
  • This retirement impacts DNS entries in the following ways:
    • Entries for existing servers continue to resolve to the same IP address to which they currently resolve until at least January 1, 2023.
    • Servers that undergo a change of IP address due to maintenance or an instance stop/restart will no longer be resolvable via their mongodbdns.com hostname.
    • All existing mongodbdns.com hostnames will stop working in May 2023.
  • Cloud Manager can manage hosts provisioned directly through AWS . See Provision Servers for Automation .
  • If you are interested in fully managed provisioning on AWS , evaluate MongoDB Atlas.

If you want to continue using Cloud Manager to manage these deployments, update the hostname for each host using one of the following methods for a replica set:

  • Rolling Resync onto New EC2 Instances
  • Update a Replica Set’s Hostnames

Considerations¶

These procedures involve stepping down the old primary and triggering at least one election for a new primary. All writes to the primary fail during the period starting when the rs.stepDown() method is received until either a new primary is elected, or if there are no electable secondaries, the original primary resumes normal operation. For MongoDB versions 4.0 and earlier, all client connections are closed.

Consider performing this procedure during a maintenance window during which applications stop all write operations to the cluster.

To learn more about elections, see rs.stepDown() behavior and Replica Set Elections .

Rolling Resync onto New EC2 Instances¶

1

Create a new EC2 instance for each member of the replica set.¶

2

Replace each non-primary replica set member with a new EC2 instance.¶

  1. Add a new instance to the replica set using its EC2 hostname. To learn more, see Add Members to a Replica Set.
  2. Wait for the initial sync to complete. To learn how to get the status of an initial sync, see the MongoDB manual.
  3. Remove one old replica set member with a mongodbdns.com hostname. To learn more, see Remove Members from Replica Set.

Repeat for each non-primary replica set member.

3

Change your application connection string to use the AWS EC2 hostnames.¶

4

Replace the primary with a new EC2 instance.¶

  1. Add the last new instance to the replica set using its EC2 hostname. To learn more, see Add Members to a Replica Set.

  2. Wait for the initial sync to complete. To learn how to get the status of an initial sync, see the MongoDB manual.

  3. Connect to the primary and step it down. To learn more, see rs.stepDown() .

    Note

    Stepping down the primary triggers at least one election for a new primary. To learn more about elections, see Replica Set Elections .

  4. Remove the old primary with the mongodbdns.com hostname from the replica set. To learn more, see Remove Members from Replica Set.

Update a Replica Set’s Hostnames¶

Follow the Change Hostnames while Maintaining Replica Set Availability procedure in the MongoDB manual.

An overview of the linked procedure is as follows:

1

Connect to the primary.¶

2

Remove a secondary member from the replica set and re-add it using its EC2 hostname.¶

Repeat for each non-primary member of the replica set.

3

Change your application connection string to use the AWS EC2 hostnames.¶

4

Reconnect to the primary and step it down.¶

Note

Stepping down the primary triggers at least one election for a new primary. To learn more about elections, see Replica Set Elections .

5

Connect to the new primary.¶

6

Remove the old primary from the replica set and re-add it using its EC2 hostname.¶

Cloud Manager collects log information for both MongoDB processes and its agents. For MongoDB processes, you can access both real-time logs and on-disk logs.

  • The MongoDB logs provide the diagnostic logging information for your mongod and mongos processes.
  • The Agent logs provide insight into the behavior of your Cloud Manager agents.

MongoDB Real-Time Logs¶

The MongoDB Agent issues the getLog command with every monitoring ping. This command collects log entries from RAM cache of each MongoDB process.

Cloud Manager enables real-time log collection by default. You can disable log collection for either all MongoDB deployments in a Cloud Manager project or for individual MongoDB deployments . If you disable log collection, Cloud Manager continues to display previously collected log entries.

1

Click Settings , then Project Settings

2

Toggle the Collect Logs For All Hosts option to Yes or No , as desired.¶

MongoDB On-Disk Logs¶

Cloud Manager collects on-disk logs even if the MongoDB instance is not running. The MongoDB Agent collects the logs from the location you specified in the MongoDB systemLog.path configuration option. The MongoDB on-disk logs are a subset of the real-time logs and therefore less verbose.

Note

This option isn’t available for deployed MongoDB processes if the systemLog.destination property is set to syslog .

You can configure log rotation for the on-disk logs. Cloud Manager rotates logs by default.

This procedure rotates both system and audit logs for Cloud Manager.

Configure Log Rotation¶

Cloud Manager can rotate and compress logs for clusters that the MongoDB Agent manages. If the MongoDB Agent only monitors a cluster, it ignores that cluster’s logs.

Important

If you’re running MongoDB Enterprise version 5.0 or later and MongoDB Agent 11.11.0.7355 or later, you can:

  • Set separate rules for rotating server logs and audit logs.
  • Compress and delete audit logs using Cloud Manager. For security reasons, we recommend managing your audit log compression and deletion outside of Cloud Manager.

If you’re running earlier versions of MongoDB Enterprise or the MongoDB Agent, Cloud Manager:

  • Uses your System Log Rotation settings to rotate both the server logs and the audit logs.
  • Doesn’t compress or delete audit logs. If you configure compression and deletion, Cloud Manager applies these settings to the server logs only.

MongoDB Community users can rotate, compress, and delete the server logs only.

Note

When using this feature, disable any platform-based log-rotation services like logrotate . If the MongoDB Agent only monitors the cluster, that cluster may use platform-based services.

1

Open the MongoDB Log Settings

  1. Click Deployment .
  2. In the More drop-down list, click MongoDB Log Settings .
2

Enable log rotation.¶

Toggle System Log Rotation to ON to rotate server logs.

MongoDB Enterprise users running MongoDB Enterprise version 5.0 or later and MongoDB Agent 11.11.0.7355 and later can also toggle Audit Log Rotation to ON to rotate audit logs and configure audit log rotation separately.

If you’re running earlier versions of MongoDB Enterprise or the MongoDB Agent, setting System Log Rotation to ON also rotates audit logs.

Set log rotation to OFF if you don’t want Cloud Manager to rotate its logs. Log rotation is OFF by default.

After you enable log rotation, Cloud Manager displays additional log rotation settings.

3

Configure the log rotation settings.¶

Cloud Manager rotates the logs on your MongoDB hosts per the following settings:

Field Necessity Action Default
Size Threshold (MB) Required Cloud Manager rotates log files that exceed this maximum log file size. 1000
Time Threshold (Hours) Required Cloud Manager rotates logs that exceed this duration. 24
Max Uncompressed Files Optional

Log files can remain uncompressed until they exceed this number of files. Cloud Manager compresses the oldest log files first.

If you leave this setting empty, Cloud Manager will use the default of 5 .

5
Max Percent of Disk Optional

Log files can take up to this percent of disk space on your MongoDB host’s log volume. Cloud Manager deletes the oldest log files once they exceed this disk threshold.

If you leave this setting empty, Cloud Manager will use the default of 2% .

2%
Total Number of Files Optional Total number of log files. If a number is not specified, the total number of log files defaults to 0 and is determined by other Rotate Logs settings. 0

When you are done, click Save to review your changes.

Click Confirm & Deploy to deploy your changes.¶

Otherwise, click Cancel and you can make additional changes.

Agent Logs¶

Cloud Manager collects logs for all your MongoDB Agents.

View Agent Logs¶

1

Click Deployment , then the Agents tab, then Agent Logs

The page displays logs for the type of agent selected in the View drop-down list. The page filters logs according to any filters selected in through the gear icon.
