Hi,

I’ve been looking at some random trend graphs in our system, and it seems that all have the same start time of 1 year ago.

Is this configureable?

We have this setting in Db.xml:

<Maintenance monthsToKeep=”36″ limitByMonths=”True” limitByNumber=”False”>

Doc: https://help.dataminer.services/dataminer/DataMinerUserGuide/part_7/SkylineDataminerFolder/DB_xml.htm?rhhlterm=db.xml&rhsyns=%20

I’m not sure if this setting should affect trending history?

Hi Jan-Terje,

You can define how long alarm and trend data should be kept in the system using the TTL overrides (more info here).

The Time To Live settings are available through the system settings page in system center.
