Correcting invalid zero value for data monitoring

A computer system for data monitoring management, the computer system comprising:

• one or more processors, one or more computer-readable memories, and program instructions stored on at least one of the one or more computer-readable memories for execution by at least one of the one or more processors to cause the computer system to:
• receive a first invalid zero value candidate from a data stream;
• receive a memory location for the first invalid zero value candidate;
• establish at a first time an access connection to the memory location;
• check at a second time subsequent to the first time the access connection to the memory location;
• and
• determine whether the first invalid zero value candidate contains an invalid zero value based on the checking.

A computer program product for data monitoring management, the computer program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• receive a first invalid zero value candidate from a data stream;
• receive a memory location for the first invalid zero value candidate;
• establish at a first time an access connection to the memory location;
• check at a second time subsequent to the first time the access connection to the memory location;
• and
• determine whether the first invalid zero value candidate contains an invalid zero value based on the checking.
