Want to try Hazelcast 5.0?

We’ve combined the in-memory storage of IMDG with the stream processing power of Jet to bring you an all new Hazelcast platform.

Management Center

Hazelcast Management Center enables you to monitor and manage your cluster members running Hazelcast. In addition to monitoring the overall state of your clusters, you can also analyze and browse your data structures in detail, update map configurations and take thread dumps from members. You can run scripts (JavaScript, Groovy, etc.) and commands on your members with its scripting and console modules.

See the Management Center documentation for its usage details.

Toggle Scripting Support

The support for script execution is disabled by default. The reason is security. Script engines allow to access the underlying system on the members (files and other resources). Scripts access the system, on which the member runs, with permissions of the running user.

Scripting can be allowed or prevented by specifying the scripting-enabled attribute of the management-center element within the Hazelcast member configuration file, as shown below:

  • XML

  • YAML

<hazelcast>
    ...
    <management-center scripting-enabled="false" />
    ...
</hazelcast>
hazelcast:
  management-center:
    scripting-enabled: false

Note that the JSR 223 API is used in Hazelcast IMDG to support scripting.

Limiting Source Addresses

It’s possible to restrict the source IP addresses from which Management Center operations are allowed. By default all source connections are allowed.

Defining these source addresses is possible through the trusted-interfaces configuration element. The wildcard (*) and ranges can be used. See the following example:

  • XML

  • YAML

<hazelcast>
    ...
    <management-center>
        <trusted-interfaces>
            <interface>192.168.1.*</interface>
        </trusted-interfaces>
    </management-center>
    ...
</hazelcast>
hazelcast:
  management-center:
    trusted-interfaces:
      - 192.168.1.*
