What's the minimum time frame of data that requires to be saved in the database to benefit from the AI capabilities?
Dear Bruno,
Thanks for your question. Let me go over the main features to give you an idea of how much time is required for them:
Alarm focus: In principle no alarm history is required, but it will need approximately one week of learning before it will give good results. If a week of alarm history is available the first time it is activated, it will use this week for its initial learning
Alarm grouping: the current version uses metadata in the system to group together focussed alarms. It is up and running as soon as alarm focus is up and running.
Anomaly detection: You should have at least one full week of data before expecting any suggestions / anomalies in your alarm console, but the trend graph will start showing behavioral changes earlier on (the most obvious ones after 4 hours, other more subtle ones will pop up over time)
Forecasting: Forecasting is done on several aggregated levels: the real time level, the 5' averages, the hourly averages and daily averages. A forecast will be displayed on the trend graph for each level. More long term predictions (ie further into the future) will use averaged data, whether short term predictions use real time data. In order to predict, we need at least 50 points, so after 50 days you will start seeing the long term prediction in cube, after 50 hours the mid term,... The more data we have, the longer our predictions.
Proactive cap detection: this algorithm relies on the above mentioned forecasting algorithm to proactively detect issues. This means that the longer ahead you want to be able to predict issues, the more historical data you need. As a rule of thumb, if you want to start predicting issues n hours in advance, you need 10*n hours of history. In particular, you'll need about 10 days of data if you want to predict an issue 1 day ahead of time.
State icons: State icons reflect the behavior of a parameter in a recent time window. The duration of this time window is configurable, but it is set to 1 hour by default. In this case, the latest you should see state icons is after 1 hour, but typically you will see them earlier on due to a data prefetching routine.
Pattern matching: pattern matching works as soon as you have enough data to select your pattern.
