Time to upgrade! NAM is scheduled for end of support. It's time to move to Dynatrace our all-in-one software intelligence platform.

Changing NAM Console configuration settings

After you install the NAM Console, you can modify the following configuration settings. Some of the settings are optional and should be changed only when necessary.

Change memory settings

(Optional) You can improve the performance of NAM Console by increasing its Java heap size. By default, the maximum heap size is 2048 MB.

  1. Stop Dynatrace Watchdog Service.
    This will also stop the NAM Console service.
  2. Open the Registry Editor.
    Select Start ► Run, and then type regedit and click OK.
  3. Browse to the following registry key: HKEY_LOCAL_MACHINE > Software > Adlex > Watchdog > Dynatrace NAM Console.
  4. Modify the javaParams value.
    It includes the heap size parameters in the following format: -Xms256m -Xmx2048m
    • Change the -Xms parameter to change the initial heap size (in megabytes).
      For example, to set the initial size to 1GB, use: -Xms1024m
    • Change the -Xmx parameter to change the maximum heap size (in megabytes).
      For example, to set the maximum size to 4GB, use: -Xmx4096m
  5. After changing the registry settings, start Dynatrace Watchdog Service. It will in turn start the NAM Console.

Update security certificate

The default certificate provided with the NAM Console server installation is unsigned. If your security policy requires that a signed certificate be used for the NAM Console server, you can provide your own certificate issued by a trusted authority.

New in NAM 2019

Applies to NAM 2019+ Starting with NAM 2019, we have a certificate management tool that takes care of the tasks handled by the keytool utility in earlier releases.

  • If you are running an earlier release (or you prefer to use a command line tool to manage your certificates), see the procedures below to create a keystore, create and submit a CSR, and import a certificate.
  • If you are running NAM 2019 or later, see How to configure SSL for NAM Console 2019 for instructions on using the new certificate management tool.

Creating a new keystore

Use the keytool utility to create a keystore.

Creating and submitting a certificate signing request (CSR)

Use the keytool command to create a CSR file. You are required to enter the password you defined earlier.

keytool –certreq –alias mykey –keyalg RSA –file certReq.csr –keystore keystore

Importing the certificates obtained from a certificate authority

Most end-user certificates are issued by intermediate certificate authorities, so you have to import not only the certificate reply, but also add a trusted certificate entry for each certificate in the chain: intermediate and root certificate. Use the keytool command for both types of input operations, noting that if the alias does not point to a key entry, then the keytool command assumes you are adding a trusted certificate entry – one of the certificates in the chain. If the alias points to a key entry, then the keytool command assumes you are importing a certificate reply.
