Abstract: The method of some embodiments allocates a secondary network interface for a pod, which has a primary network interface, in a container network operating on an underlying logical network. The method receives an ND that designates a network segment. The method receives the pod, wherein the pod includes an identifier of the ND. The method then creates a secondary network interface for the pod and connects the secondary network interface to the network segment. In some embodiments, the pods include multiple ND identifiers that each identify a network segment. The method of such embodiments creates multiple secondary network interfaces and attaches the multiple network segments to the multiple secondary network interfaces.

Abstract: Techniques for measuring the memory usage of Java programs are provided. In one set of embodiments, a Java agent can detect that a Java Virtual Machine (JVM) is loading a Java class used by a Java program. The Java agent can further determine a class name of the Java class and determine that the class name matches an entry in a first list included in a user-defined configuration file. The Java agent can then dynamically insert bytecode into a constructor of the Java class, where the inserted bytecode includes logic for registering a memory reference to an object created via the constructor.

Abstract: Example methods and systems for intent-based network virtualization design are disclosed. One example may comprise: obtaining configuration information and traffic information associated with multiple virtualized computing instances, processing the configuration information and traffic information to identify network connectivity intents and mapping the network connectivity intents to a logical network topology template. Based on a first switching intent, a first group may be assigned to a first logical network domain and the logical network topology template configured to include a first logical switching element. Based on a second switching intent, a second group may be assigned to a second logical network domain and the logical network topology template configured to include a second logical switching element. Based on a routing intent, the logical network topology template may be configured to include a logical routing element.

One example may comprise: obtaining configuration information and traffic information associated with multiple virtualized computing instances, processing the configuration information and traffic information to identify network connectivity intents and mapping the network connectivity intents to a logical network topology template. Based on a switching intent, a first group may be assigned to a logical network domain and the logical network topology template modified to include a logical switching element. Based on a routing intent, the logical network topology template may be modified to include a logical routing element. A logical network may be configured based on the modified logical network topology template to satisfy the switching intent and routing intent.

Abstract: Some embodiments provide a method of tracking errors in a container cluster network overlaying a software defined network (SDN), sometimes referred to as a virtual network. The method sends a request to instantiate a container cluster network object to an SDN manager of the SDN. The method then receives an identifier of a network resource of the SDN for instantiating the container cluster network object. The method associates the identified network resource with the container cluster network object. The method then receives an error message regarding the network resource from the SDN manager. The method identifies the error message as applying to the container cluster network object. The error message, in some embodiments, indicates a failure to initialize the network resource. The container cluster network object may be a namespace, a pod of containers, or a service.
