Setting the default sliding window size for real-time trending

It is possible to configure the default size of the sliding window for real-time trending for a particular DMA. All elements on that DMA will then inherit this default value, unless it is overridden on element level.

Note

The user permission Configure trend templates is required to modify this setting.

To configure the default size:

1. Go to System Center > System settings > time to live

   Note

   If your DMS uses Storage as a Service, TTL settings are automatically configured and may not be available for manual adjustment on the System settings > time to live tab in System Center, depending on your DataMiner version.

2. Under Trending, in the Real-time box, specify the new window size.

   Note

   At present, trending information is not saved in the indexing database. As such, if your DMS uses an indexing database, only the settings in the Local column of the time to live page will be taken into account for trending.

3. Click the Apply button.

Note

For more information on the TTL configuration, including how to specify an override for a specific protocol or protocol version, see Specifying TTL overrides.
