Hi Bruno,
The so-called average trending (minute, hour, daily records) will always store the average, min and max value of that window. Percentile is something which is calculated and added by the client application, this is not stored in the database.

Hi Bruno,

In a Trend template, you indeed have two checkboxes, ‘real-time’ and ‘average’. You can select one or the other, or both (or none).

If you activate ‘real-time’, then DataMiner will store each change we detect in the value of that parameter into the database (and this will stay in the database for the configure TTL, which is by default 24h).

If you activate ‘average’, then DataMiner will store the minute, hour and daily records into the database. So, with one checkbox, all those average records are being stored. The minute records are, by default, 5 minute slots during one month. The hour records are, by default, one hour slots during one year. Daily is not enabled by default. In other words, DataMiner will keep track of the min, max and average values and each 5 minutes it will store a record in the database for the last 5 minutes, and each hour it will store a record in the database for the last hour.

So, to answer your questions:
1. Indeed, when you only activate the ‘average’ checkbox in the Trend template, only the average values will be stored (together with min and mix). But, not only for the minute records, also for the hour records.
2. Indeed, activating the ‘real-time’ checkbox, will store those real-time records only. And you can combine both checkboxes if you wish.

Let me know if something would not be completely clear yet.
