Abstract

A computing system includes a plurality of physical hosts; a first application of a first tenant and a second application of a second tenant distributed over the plurality of physical hosts; and a plurality of virtual switches with a plurality of ports, each switch associated with a corresponding one of the physical hosts. A first virtual network couples the plurality of first application components and a second virtual network, isolated from the first virtual network, couples the plurality of second application components. A cloud management dashboard coupled to a software defined network controller is configured to receive an application performance monitoring request from a tenant and instruct the software defined network controller to turn on port mirroring on at least a portion of those of the plurality of ports corresponding to the application of the requesting tenant, to mirror corresponding packets to a packet data repository.

First claim

What is claimed is:

1. A computing system comprising:
a packet data repository;
a plurality of physical hosts;
a first application of a first tenant, comprising a plurality of first application components, distributed over said plurality of physical hosts;
a second application of a second tenant, comprising a plurality of second application components, distributed over said plurality of physical hosts;
a plurality of virtual switches each associated with a corresponding one of said physical hosts, each of said virtual switches having a plurality of ports;
a first virtual network coupling said plurality of first application components;
a second virtual network, isolated from said first virtual network, coupling said plurality of second application components;
a software defined network controller coupled to said virtual switches;
a cloud management dashboard coupled to said software defined network controller and configured to receive an application performance monitoring request from at least one of said first tenant and said second tenant, and, responsive to said application performance monitoring request, instruct said software defined network controller to turn on port mirroring only for those of said plurality of ports which correspond to problematic ones of said first and second application components, said problematic ones of said first and second application components corresponding to said application of said at least one of said first tenant and said second tenant and exhibiting at least one software problem, to mirror corresponding packets to said packet data repository, wherein said cloud management dashboard is further configured to trace network communication among microservices and combine application layer logs and said network communication traces, wherein said port mirroring is controlled based on said combined application layer logs and network communication traces; and
one or more edge switches hosting individual ones of said microservices, wherein said port mirroring is implemented on said one or more edge switches.

2. The system of claim 1 , further comprising a decoding and analytics module which receives said mirrored corresponding packets from said port mirroring and outputs latency data to locate a bottleneck in said application of said at least one of said first tenant and said second tenant to permit allocation of computing resources to relieve said bottleneck.

3. The system of claim 2 , wherein said turning on port mirroring only for those of said plurality of ports which correspond to problematic ones of said first and second application components is in response to a first application performance monitoring request and wherein said cloud management dashboard is configured to instruct said software defined network controller to turn on, in response to a second application performance request, said port mirroring on all of those of said plurality of ports corresponding to said application of said at least one of said first tenant and said second tenant.

4. The system of claim 2 , wherein said turning on port mirroring only for those of said plurality of ports which correspond to problematic ones of said first and second application components is in response to a first application performance monitoring request and wherein said cloud management dashboard instructs said software defined network controller to turn on, in response to a second application performance request, said port mirroring immediately upon receipt of said application performance monitoring request.

5. The system of claim 2 , wherein said turning on port mirroring only for those of said plurality of ports which correspond to problematic ones of said first and second application components is in response to a first application performance monitoring request and wherein said cloud management dashboard instructs said software defined network controller to turn on, in response to a second application performance request, said port mirroring on demand, subsequent to receipt of said application performance monitoring request, to provide staged port mirroring.

6. A method of providing agentless application performance monitoring in a system, said method comprising:
distributing a first application of a first tenant, said first application comprising a plurality of first application components, over a plurality of physical hosts, said plurality of physical hosts coupled by a first virtual network;
distributing a second application of a second tenant, said second application comprising a plurality of second application components, over said plurality of physical hosts, said plurality of physical hosts coupled by a second virtual network, isolated from said first virtual network, said method further comprising:
receiving, at a cloud management dashboard, an application performance monitoring request from at least one of said first tenant and said second tenant;
tracing network communication among microservices and combining application layer logs and said network communication traces, wherein port mirroring is controlled based on said combined application layer logs and network communication traces; and
responsive to said application performance monitoring request, said cloud management dashboard instructing a software defined network controller to turn on said port mirroring, said software defined network controller being coupled to:
said cloud management dashboard, and
a plurality of virtual switches each associated with a corresponding one of said physical hosts, each of said virtual switches having a plurality of ports, said cloud management dashboard instructing said software defined network controller to turn on port mirroring only for those of said plurality of ports which correspond to problematic ones of said first and second application components, said problematic ones of said first and second application components corresponding to said application of said at least one of said first tenant and said second tenant and exhibiting at least one software problem, to mirror corresponding packets to said packet data repository.

7. The method of claim 6 , wherein said turning on port mirroring only for those of said plurality of ports which correspond to problematic ones of said first and second application components is in response to a first application performance monitoring request and wherein said cloud management dashboard is configured to instruct said software defined network controller to turn on, in response to a second application performance request, said port mirroring on all of those of said plurality of ports corresponding to said application of said at least one of said first tenant and said second tenant.

8. The method of claim 6 , wherein said turning on port mirroring only for those of said plurality of ports which correspond to problematic ones of said first and second application components is in response to a first application performance monitoring request and wherein said cloud management dashboard instructs said software defined network controller to turn on, in response to a second application performance request, said port mirroring immediately upon receipt of said application performance monitoring request.

9. The method of claim 6 , wherein said turning on port mirroring only for those of said plurality of ports which correspond to problematic ones of said first and second application components is in response to a first application performance monitoring request and wherein said cloud management dashboard instructs said software defined network controller to turn on, in response to a second application performance request, said port mirroring on demand, subsequent to receipt of said application performance monitoring
