Abstract
Synchronous replication end to end latency reporting is disclosed. In various embodiments, performance data associated with processing and replicating synchronously file system operation requests from a primary storage system to a secondary storage system is received from a data storage system via a communication interface. Performance data associated with an application-level workload is aggregated. A representation of the aggregated performance data for the application-level workload is provided via a user interface.
Claims16
A data storage system, comprising:
- a communication interface configured to receive, from a data storage system, performance data associated with processing and synchronously replicating file system operation requests;
- and
- a processor coupled to the communication interface and configured to:
- aggregate performance data associated with an application-level workload, wherein the performance data includes a first set of data associated with a primary storage system associated with the application-level workload and a secondary storage system associated with the application-level workload;
- and
- provide, via a user interface, a representation of the aggregated performance data for the application-level workload, wherein:
- the representation of the aggregated performance data includes a representation of a latency associated with the primary storage system and a representation of a latency associated with the secondary storage system, each representation of latency including factors contributing to each latency;
- and
- at least one of the latency associated with the primary storage system and the latency associated with the secondary storage system includes a measured barrier latency corresponding to an amount of time that it takes to decide whether a given operation is to be replicated synchronously;
- wherein the application-level workload comprises a virtual machine;
- wherein the processor is further configured to:
- create a mapping between the virtual machine and a set of one or more files, by tracking, at a storage system level, data indicating which files are associated with which virtual machines;
- use said mapping to aggregate performance data associated with the one or more files;
- store the aggregated performance data associated with the one or more files in a manner that associates the aggregated performance data associated with the one or more files with the virtual machine;
- and
- wherein the stored aggregated performance data associated with the one or more files is used to provide at least said first set of data on a per virtual machine basis.
