  3. 3. Other Parameters

1. Database #

PostgreSQL database contains many parameters that affect performance. An automatic procedure will be run for optimizing them during installation, but you may also tweak them manually. The exact procedure of how to do this is out of the scope of this manual.

2. General Properties #

Some general application parameters of Qosium Storage are found in the file <path>/QosiumStorage/html/application.properties. It uses the format:

<parameter.name>=<parameter_value>

Next, we go through some typically used parameters.

2.1. qosiumstorage.port #

Defines the port (TCP) to which the results reception server is bound.

  • Values: <TCP port> – Your specified port at range 1 - 65534
  • Default: 8888
If Storage is behind a firewall and you wish to have access from outside, you have to open this port to the firewall.

2.2. qosiumstorage.averaging.qoe.selection #

This parameter is used to define which QoE method is used in the general statistic calculation.

  • Values:
    • 0 – PSQA is used
    • 1 – GQoSM is used
  • Default: 1

2.3. qosiumstorage.performance.report.interval #

The Status tab in the Qosium Storage’s UI shows internal status of the system. This parameter defines its reporting interval.

  • Values: 1000 – 2147483647
  • Default: 10000
  • Unit: milliseconds

2.4. qosiumstorage.heatmap.area.left #

This parameter is one of the four parameters defining the heatmap maximum visualization area. The parameter here defines the left side limit of the longitude axis.

  • Values: -180 – 180
  • Default: 20.61
  • Unit: degrees

2.5. qosiumstorage.heatmap.area.right #

Defines the right side limit of the longitude axis.

  • Values: -180 – 180
  • Default: 31.65
  • Unit: degrees

2.6. qosiumstorage.heatmap.area.top #

Defines the top side limit of the latitude axis.

  • Values: -90 – 90
  • Default: 70.22
  • Unit: degrees

2.7. qosiumstorage.heatmap.area.bottom #

Defines the bottom side limit of the latitude axis.

  • Values: -90 – 90
  • Default: 59.65
  • Unit: degrees

3. Other Parameters #

In addition to the ones presented above, there are many more parameters of Qosium Storage found in the file <path>/QosiumStorage/html/application.properties. Most of them, however, are such that you don’t need to modify them. Reach out to Kaitotek support for more information on the parameters.
