Cognitive analysis for healing an IT system

A computer program product for healing an Information Technology (IT) system, wherein said computer program product comprises a non-transitory computer readable storage medium having program code stored thereon, and wherein said program code is read and executed by a processor to perform a method comprising:

• receiving an error log from an IT system, wherein the error log comprises a record of one or more errors currently being detected by at least one sensor in the IT system;
• receiving an error history log, wherein the error history log describes a history of past errors that have occurred in the IT system;
• receiving a listing of alternative IT systems from a configuration management database (CMDB) server, wherein the alternative IT systems have been predetermined to have a same functionality as the IT system that is currently experiencing the one or more errors;
• receiving, by the cognitive computing hardware system, a list of incidents and changes that have occurred on the IT system;
• receiving a record of real-time events from at least one external event server, wherein the real-time events are external to the IT system, and wherein the real-time events impact a performance of the alternative IT systems;
• generating a prioritized set of solutions to heal the IT system, wherein solutions from the prioritized set of solutions are prioritized based on the error history log, the listing of alternative IT systems, and the record of real-time events;
• and
• transmitting, to the IT system via an implementer system, a highest prioritized solution from the prioritized set of solutions, wherein the highest prioritized solution has a greater probability of healing the one or more errors, that are in the error history log and that are detected by said at least one sensor in the IT system, than any other solution, from the prioritized set of solutions, based on the error history log, the listing of alternative IT systems, and the record of real-time events;
• and
• implementing the highest prioritized solution from the prioritized set of solutions in order to heal the one or more errors currently being detected by said at least one sensor in the IT system.

A system comprising:

• a hardware processor, a computer readable memory, and a computer readable storage media;
• first program instructions to receive an error log from an IT system, wherein the error log comprises a record of one or more errors currently being detected by at least one sensor in the IT system;
• second program instructions to receive an error history log, wherein the error history log describes a history of past errors that have occurred in the IT system;
• third program instructions to receive a listing of alternative IT systems from a configuration management database (CMDB) server, wherein the alternative IT systems have been predetermined to have a same functionality as the IT system that is currently experiencing the one or more errors;
• fourth program instructions to receive a list of incidents and changes that have occurred on the IT system;
• fifth program instructions to receive a record of real-time events from at least one external event server, wherein the real-time events are external to the IT system, and wherein the real-time events impact a performance of the alternative IT systems;
• sixth program instructions to generate a prioritized set of solutions to heal the IT system, wherein solutions from the prioritized set of solutions are prioritized based on the error history log, the listing of alternative IT systems, and the record of real-time events;
• and
• seventh program instructions to transmit, to the IT system via an implementer system, a highest prioritized solution from the prioritized set of solutions, wherein the highest prioritized solution has a greater probability of healing the one or more errors, that are in the error history log and that are detected by said at least one sensor in the IT system, than any other solution, from the prioritized set of solutions, based on the error history log, the listing of alternative IT systems, and the record of real-time events;
• and
• eighth program instructions to implement, by the implementer system, the highest prioritized solution from the prioritized set of solutions in order to heal the one or more errors currently being detected by said at least one sensor in the IT system;
• and wherein
• the first, second, third, fourth, fifth, sixth, seventh, and eighth program instructions are stored on the computer readable storage media for execution by the hardware processor via the computer readable memory.
