A method ( 300 ) for delivering monitoring data is proposed. The monitoring data is collected on a central server from selected managed computers, in order to be provided to multiple clients (in response to periodic requests). In the method of the invention, for each managed computer the central server estimates ( 336;351 - 354 ) an expected duration of a next collection of the monitoring data (according to the duration of one or more preceding collections). A trigger delay of the next collection is then calculated by subtracting ( 366 ) a time advance to the expected time of the next request (defined by the corresponding period); the time advance is based ( 339 - 348;357;363 ) on the expected duration of the next collection, suitably incremented by a safety margin (so as to prevent receiving the next request before the corresponding collection has completed). The monitoring data is then pre-fetched ( 315 - 324 ) from the managed computer when the trigger delay expires.
