Abstract

The invention comprises a method and system for monitoring the performance of a computer coupled to a computer network and, optionally, generating alerts when the performance of the computer has reached an alertable level. The method of monitoring the performance of the computer comprises repeatedly obtaining performance data using the computer wherein at least one performance value comprises a measure of the performance of the computer. The performance data is automatically sent over the computer network to a second computer coupled to the computer network. The performance data is then logged to a performance database using the second computer.
