SELF-DIAGNOSING PROCESSES USING QR-CODE

Systems, methods and computer program products for diagnosing consistency of a software cluster are provided herein. The system includes a deployment manager configured to function as a master node of the software cluster, a plurality of nodes connected to the deployment manager, and an electronic device or devices registered with the deployment manager. The deployment manager ban be configured to generate a master quick response (QR) code and each of the plurality of nodes can be configured to generate a node QR code. The electronic device(s) may be associated with a system administrator and may also be installed with application software. Embodiments may allow the system administrator to encode, manage and analyze diagnostic information of the nodes in the software cluster utilizing the master QR code and the node QR code in an efficient manner.
