How to display the samplers with the sampling interval from a gateway?
This information can be obtained from the Gateway by using the Gateway-SQL plug-in. The query works by looking up the sample interval property value for each sampler on the gateway. An example of the dataview is shown below.
Depending on the estate of your gateway the sampler may be expensive in terms of performance and may take some time to run. Due to thid reason, the sampler is configured on purpose, not to sample on startup and does not run on its own. It has a 0 sampling interval. As a result, you will see 0 rows, Manual sampling in the dataview when the sampler is initialized.
To run the sampler manually, click on the Sample now or refresh button in the dataview.
For more information, see the Gateway-SQL section on the Gateway Plug-Ins documentation. The SQL statements are based on SQLite.
