 |
Value exceeding a critical threshold: the separate analysis of each performance indicator makes it possible to detect the most frequent problems (load, CRC errors, congestion, unavailability) |
 |
Health of the network: the simultaneous analysis of all the performance indicators makes it possible to determine the general health of the network and to warn the user while it is still time to act. |
 |
Abnormal Differential (going up): the daily calculation of the values awaited for each indicator and the comparison with the result of measurements makes it possible to detect " abnormal " values and thus to announce the " unusual " behaviors of the network. |
 |
Idem with a Differential going down |
 |
Short-term tendency: the analysis of the variations of the indicators day after day, makes it possible to emphasize the tendencies, to foresee the evolution of the performances of equipments and thus to warn the user before the appearance of a problem. |
 |
Idem with Medium-term Tendency |

The critical time ranges detected by FastExpert are symbolized by color codes. In the following sample, yellow, orange and red stickers highlight an excessive load (IN). |
