Agentless distributed monitoring of microservices through a virtual switch

A system comprising:

• a centralized controller;
• a first microservice and a second microservice, the first and second microservices associated with a distributed application;
• a first virtual switch running on a first host associated with the first microservice and a second virtual switch running on a second host associated with the second microservice;
• and
• a gateway interposed between the centralized controller and the first and second microservices,
• wherein the centralized controller is operable to configure a monitoring policy to apply to the first microservice and the second microservice,
• wherein the first virtual switch gathers first information from the first microservice in accord with the monitoring policy and send the first information to the gateway,
• wherein the second virtual switch gathers second information from the second microservice in accord with the monitoring policy and send the first information to the gateway,
• wherein the gateway sends the first information and second information to the centralized controller, and
• wherein the centralized controller aggregates the first information and the second information and reports the aggregated information via a user interface.

One or more non-transitory computer-readable storage media containing instructions that, when executed by one or more processors within a system for monitoring a distributed application, cause the system to perform operations comprising:

• at a centralized controller, configuring a monitoring policy to apply to a first microservice on a first host and a second microservice on a second host, wherein the first and second microservices are associated with a distributed application;
• gathering first information from the first microservice, by a first virtual switch, in accord with the monitoring policy;
• gathering second information from the second microservice, by a second virtual switch, in accord with the monitoring policy;
• sending the first information from the first virtual switch to the centralized controller through a first gateway;
• sending the second information from the second virtual switch to the centralized controller through a second gateway;
• aggregating the first information and the second information at the centralized controller;
• and
• reporting the aggregated information via a user interface.
