addVANTAGE Pro 6.4 Administrator Guide APPENDIX

Public Trends

addVANTAGE Pro and select one of the RAS profiles you just created from the

dial-up connection dropdown shown in Figure 59 on page 51.

Figure 117. RAS Advanced TCP/IP Settings in Windows 2000 and XP

Note: The dial-up feature is currently implemented and works only under Windows

2000 and XP. For these operating systems, note that the option “Use default

gateway on remote network” must be unselected. To find this option, open the

Properties dialog of the RAS profile. Select the Networking tab, select Internet

Protocol (TCP/IP) and click Properties, then click Advanced and select the

General tab (see also Figure 117). In addition, if the addVANTAGE Pro server is

started as a service, both the service and the RAS profiles must belong to the

same Windows user/group (for example, Administrator). Otherwise, the server

will not be able to use the RAS profiles. By default a service under Windows is

installed and run as user System, so you will need to explicitly change this.

Public Trends

If a Trend is set as being publicly available (see page 36), you must use these

parameters to access it:

mandatory: http://localhost:8080/trend/graph?panel=YOUR_PANEL_ID

mandatory: &public=true

optional: &width=500

optional: &height=500

optional: &beginDate=20070101T00:00:00

optional: &hours=168

optional: &tagIndex=1

optional: &showLegend=true

• The panel is the node ID of the panel you'd like to view. You cannot view a

panel that has not been saved.

• The public parameter helps you avoid mixing up the logged-in user and

accessing a trend publicly. Since it is mandatory, you will probably get an

Exception if you don’t include the parameter.

• The width and height are the width/height of the requested picture in

pixels. The default values are a width of 700 and a height of 350.

• The beginDate is the date the trend should start with when it is accessed. If

you leave this parameter out, the Trend picture will be set to the date it

would use when opening it within addVANTAGE. The beginDate must be in

UTC (also known as coordinated universal time). There are two formats

used for beginDate:

• The number of seconds since 01.01.1970 can be 1203897600 to

represent today's date. Java/JavaScript programmers can easily

access this number by standard methods.

• The format that is already used in addUPI: yyyymmddThh:mm:ss,

such as 20080101T00:00:00.
