The challenge
Throughout the years the volume of data collected and logged by IGSS for graph and reporting purposes has increased dramatically. In larger installations, this means that a simple operation as viewing a graph involves reading several Gigabytes of data. Luckily, the capacity of modern networks have grown almost just as fast as the volume of IGSS LOG data in typical LAN installations.
However, in multi-user systems where one or more operator stations are connected to the IGSS Server with a WAN connection, problems may arise. The response time for an IGSS graph in WAN solutions could be way too long.
The solution
To overcome the above problem, the IGSS Data Server was implemented. The IGSS Data Server optimizes the use of the bandwidth between the IGSS Server and the WAN operator station. These operator stations will see a significant improvement in the response times when opening LOG-based graphs.
Activating the IGSS Data Server
The IGSS Data Server must be activated on the IGSS Server. It will by default run in the background without any user interface. When an operator station connects to the IGSS Server, it will detect whether the Data Server is running. If so, it will automatically use the Data Server when fetching data for LOG-based graphs. If the Data Server is not activated, data fetching will be done as in earlier versions of IGSS.
Auto starting the IGSS Data Server
To auto start the Data Server, simply select the Data Server check box on the Startup tab for the IGSS Server.
Manually starting the IGSS Data Server
You can start the Data Server manually by typing the IGSSdataserver command in the Windows Command Prompt.
It shows the following information:
Server state (running, stopped)
Number of active clients (operator stations)
Various data statistics
You can run the Data Server in hidden mode. Simply right-click the icon in the upper left corner of the window and select Hide.
Port numbers used
Port number 12401 must be open on the IGSS Server to allow communication with the IGSS Data Server. If you are using a firewall, this port must be open.
