A method is provided for determining whether the immediate state of a telecommunications switch ( ) is adequate for a software upgrade or retrofit. A report stream of text messages relating to the state of, and events occurring on, the telecommunications switch is received ( ) by a server ( ). Predetermined messages are detected in the report stream, including messages indicating hardware errors, alarms and other errors ( ). The predetermined messages have a numerical value associated therewith ( ). The numerical value reflects a probability of failure of a retrofit if the message is detected. As the predetermined messages are detected, their numerical values are accumulated into an accumulated value ( ). If the accumulated value exceeds a threshold, the switch is not fit for the retrofit ( ). The time spent receiving the report stream is determined and compared against an expected time ( ). If the time spent receiving the report stream does not exceed an expected time, then a determination regarding suitability for upgrade may not be reliable ( ). A visual portion ( ) of a user interface on a client ( ) is updated to reflect whether the switch is in an adequate state for a software upgrade. Hierarchical views of a user interface permit a user to view a failing subsystem, failure type, and associated detected messages in an organized manner.

A method is provided for determining whether the state of a telecommunications switch ( ) is adequate for a software upgrade or retrofit. A report stream of text messages relating to the state of, and events occurring on, the telecommunications switch is stored ( ) by a server ( ). Predetermined messages are detected in the report stream, including messages indicating hardware errors, alarms and other errors ( ). The predetermined messages have a numerical value associated therewith ( ). The numerical value reflects a probability of failure of a retrofit if the message is detected. As the predetermined messages are detected, their numerical values are accumulated into an accumulated value ( ). The time period the report stream covers is determined and compared against an expected time ( ). If the time period covered by the report stream does not exceed an expected time, then a determination regarding suitability for upgrade may not be reliable ( ). If the accumulated value exceeds a threshold, the switch may not be fit for the retrofit ( ). A visual portion ( ) of a user interface on a client ( ) is updated to reflect whether the switch is in an adequate state for a software upgrade. Hierarchical views of a user interface permit a user to view a failing subsystem, failure type, and associated detected messages in an organized manner.
