Why is long-term monitoring important?
Permanently running monitoring software should provide an information basis of long-term statistical data. A hierarchic fragmentation of the data by years, months, and days is useful. Many errors can be avoided, if the net is permanently monitored and the network parameters are controlled. You can often intervene before an error becomes visible for the users. Even if you do not watch the recordings on a regularly basis, you can track back if necessary.
