Abstract
A method, system, and product for monitoring the availability of a data processing system are proposed. The system runs a management application involving the periodic transmission of blocks of data from multiple local computers to a central computer. Whenever a block of data must be transmitted by a generic local computer, an expected transmission delay of a next block of data (with respect to the current one) is estimated and attached to the block of data. The central computer receiving the updated block of data can calculate an expected receiving time of the next block of data accordingly. If the next block of data is not received in due time, the central computer determines a failure of the local computer. The central computer also scans a subset of ports of the local computer, to ascertain whether the problem is due to a temporary unavailability of the application.
