Methods and devices for monitoring of network performance for container virtualization

A method performed by a monitoring container, for executing a monitoring function monitoring performance metrics of data traffic of a first task container, the method comprising:

• receiving an instantiation message to instantiate the monitoring function;
• instantiating the monitoring function in the monitoring container;
• receiving data traffic, communicated between the first task container and a second task container, which data traffic is mirrored to the monitoring container, by a switch that is attached to the first task container;
• and
• executing the monitoring function monitoring the performance metrics of the mirrored data traffic.

A server node configured to establish a monitoring function monitoring performance metrics of data traffic of a first task container of the server node, the server node being adapted to:

• provide a first monitoring container adapted to execute the monitoring function, when a task of the first task container has started;
• instantiate the monitoring function in the first monitoring container;
• mirror data traffic addressed to, or originating within, the first task container, to the first monitoring container;
• and
• execute the monitoring function in the first monitoring container monitoring the performance metrics of the data traffic being mirrored.

A server node configured to establish a monitoring function to monitor performance metrics of data traffic of a first task container in a virtual environment, the server node comprising:

• a processor;
• and
• a memory storing a computer program comprising computer program code which when run in the processor, causes the server node to:
• provide a first monitoring container adapted to execute the monitoring function, when a task of the first task container has started;
• instantiate the monitoring function in the first monitoring container;
• mirror data traffic addressed to, or originated within, the first task container, to the first monitoring container;
• and
• execute the monitoring function in the first monitoring container monitoring the performance metrics of the data traffic being mirrored.

A virtual container adapted to execute a monitoring function monitoring performance metrics of data traffic of a first task container, where the virtual container is further adapted to:

• receive an instantiation message to instantiate the monitoring function;
• instantiate the monitoring function in the virtual container;
• receive data traffic communicated between the first task container and a second task container, which data traffic is mirrored to the virtual container by a switch that is attached to the first task container;
• and
• execute the monitoring function monitoring the performance metrics of the mirrored data traffic.
