A method (200) and apparatus (150) for automatically monitoring a system (101) to detect malfunctions, wherein said system (101) generates messages (201) based upon selected data, comprising the steps of receiving messages (201) generated by said system (101), counting said messages (201) over statistically significant time periods (202) to form message subgroups (240) including selected numbers of messages, comparing the number of messages in each of said subgroups with predefined limits for that subgroup (260) to determine whether said number of messages in that subgroup (240) is statistically unusual, and generating an alert signal (270) whenever a statistically unusual number of messages is detected. |
