Self-reporting remote copy performance on a consistency group

A computer system for collecting performance data of a two-site data replication program, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• positioning at least one software application at a first site into idle mode;
• starting a consistency group corresponding to the at least one software application, wherein the starting is based on a command from a master system of the two-site data replication program, wherein the master system is at the first site;
• collecting, at the first site, primary performance data associated with the started consistency group;
• removing remaining data associated with the collected primary performance data;
• ending the collecting of the primary performance data;
• replicating the consistency group at the first site to form a copy of the consistency group;
• transmitting the copy of the consistency group to a second site for storage of the copy of the consistency group at the second site, the second site being remote from the first site;
• collecting, at the second site, secondary performance data associated with the started consistency group;
• transmitting the collected primary and secondary performance data to the master system as part of a response to a request for a snapshot copy of a logical volume of data, wherein the logical volume of data that is requested is from the at least one software application;
• bundling the collected secondary performance data to the collected primary performance data to form a bundle;
• and
• storing the bundle in a database at the first site;
• wherein the collected primary performance data relates to first aspects of the two-site data replication and the collected secondary performance data relates to second aspects of the two-site data replication, the second aspects being different than the first aspects.

A computer program product for collecting performance data of a two-site, data replication program, the computer program product comprising:

• one or more computer-readable storage media and program instructions stored on at least one of the one or more tangible storage media, the program instructions executable by a processor to cause the processor to perform a method comprising:
• positioning at least one software application at a first site into idle mode;
• starting a consistency group corresponding to the at least one software application, wherein the starting is based on a command from a master system of the two-site data replication program, wherein the master system is at the first site;
• collecting, at the first site, primary performance data associated with the started consistency group;
• removing remaining data associated with the collected primary performance data;
• ending the collecting of the primary performance data;
• replicating the consistency group at the first site to form a copy of the consistency group;
• transmitting the copy of the consistency group to a second site for storage of the copy of the consistency group at the second site, the second site being remote from the first site;
• collecting, at the second site, secondary performance data associated with the started consistency group;
• transmitting the collected primary and secondary performance data to the master system as part of a response to a request for a snapshot copy of a logical volume of data, wherein the logical volume of data that is requested is from the at least one software application;
• bundling the collected secondary performance data to the collected primary performance data to form a bundle;
• and
• storing the bundle in a database at the first site;
• wherein the collected primary performance data relates to first aspects of the two-site data replication and the collected secondary performance data relates to second aspects of the two-site data replication, the second aspects being different than the first aspects.
