Automatic resource dependency tracking and structure for maintenance of resource fault propagation

A method for providing automatic resource dependency tracking and maintenance of resource fault propagation, the method comprising:

• performing, by a resource dependency system in operative communication with a first system and the plurality of networked communication channels, a query configured to identify any application calls performed in a predetermined period of time;
• for each identified application call, building, by the resource dependency system, a corresponding transaction paragraph comprising a list of all sub-application calls performed in response to the application call;
• from each transaction paragraph, extracting, by the resource dependency system, a chronological sequence of sub-application calls found in the transaction paragraph;
• forming, by the resource dependency system, a tier pathway for each transaction paragraph, the tier pathway comprising the application call and each sub-application call, a timestamp indicating a date and time of discovery of the tier pathway and information indicating (i) the chronological sequence relating the application call and the sub-application calls, and (ii) one of a unilateral or bilateral dependency between each call in the tier pathway;
• periodically performing, by the resource dependency system, subsequent queries configured to identify application calls performed in a predetermined period of time;
• in response to each of the subsequent queries, updating the timestamp for each preexisting tier pathway in an accessible file, wherein the update of the timestamp indicates the date and time of the re-discovery of the tier pathway during a subsequent query;
• and
• in response to determining that one or more tier pathways stored in the accessible file is obsolete by examining the timestamp of tier pathway and determining that the timestamp is older than a predetermined threshold of time, purging the one or more tier pathway determined to be obsolete from the accessible file.

A computer program product for providing automatic resource dependency tracking and maintenance of resource fault propagation, the computer program product comprising:

• a non-transitory computer-readable medium comprising:
• a set of codes for causing a computer to perform a query configured to identify any application calls performed in a predetermined period of time;
• a set of codes for causing the computer to, for each identified application call, build a corresponding transaction paragraph comprising a list of all sub-application calls performed in response to the application call;
• a set of codes for causing the computer to, from each transaction paragraph, extract a chronological sequence of sub-application calls found in the transaction paragraph;
• a set of codes for causing the computer to, form a tier pathway for each transaction paragraph, the tier pathway comprising the application call and each sub-application call, a timestamp indicating a date and time of discovery of the tier pathway and information indicating (i) the chronological sequence relating the application call and the sub-application calls, and (ii) one of a unilateral or bilateral dependency between each call in the tier pathway;
• a set of codes for causing the computer to store each tier pathway in an accessible file;
• a set of codes for causing the computer to periodically perform subsequent queries configured to identify application calls performed in a predetermined period of time;
• a set of codes for causing the computer to, in response to each of the subsequent queries, update the timestamp for each preexisting tier pathway in the accessible file, wherein the update of the timestamp indicates the date and time of the re-discovery of the tier pathway during a subsequent query;
• and
• a set of codes for causing the computer to, in response to determining that one or more tier pathways stored in the accessible file is obsolete by examining the timestamp of tier pathway and determining that the timestamp is older than a predetermined threshold of time, purge the one or more tier pathway determined to be obsolete from the accessible file.
