What are Query Limitations in the LGH File Inspector

What limitations, if any, exist in the LGH File Inspector once it is licensed?

A fully licensed LGH File Inspector installation is only limited in three ways:

  1. A single query cannot contain more than 1024 tags; larger queries must be split into multiple queries
  2. A single query cannot result in more than roughly 15,000,000 (~15 million) records being retrieved; larger queries must be split into multiple queries, or the interval at which data is queried must be reduced. (The exact record count limit can vary)
  3. InTouch does not store data in the LGH Files faster than 1 second (1000 ms). As a result the LGH File Inspector is not able to query data from the LGH File faster than, or at a greater granularity than, 1 second. 

The first two limitations mentioned above are to optimize the product, and prevent memory related issues associated with loading too much data at once.

For larger queries the Advanced Query can be used to easily modify start and end times, tag lists, as well as the polling frequency/interval. See the product documentation for more details.
