The goal is to create a trend graph using Legacy Dashboard that displays more than one curve (see example below).
Instead of plotting data from regular parameters, I need to use data coming from enhanced service stand-alone parameters.
I want to know if this is feasible using the Legacy Dashboards, otherwise I will explore other methods available.
I have tried some options without success:
- Regular trend graph component
- it allows me to choose the enhanced service but cannot display parameters trend data
- Returns "No trend data available"
- it allows me to choose the enhanced service but cannot display parameters trend data
- Service trend parameter component
- cannot display more than 1 curve per graph.
- when using wildcard that matches the name of more than one parameter, it creates one graph per parameter.
Your use-case should be possible with the regular trend parameter component. If it shows "No Trend Data Available", then it is the DMA agent telling Dashboards that it doesn't have trend data available for this parameter in the selected time span for the configured type of trend data (average or real-time).
The service trend parameter component will use the configured parameter name (can be a wildcard) to look for parameters of the elements/services within the specified service. This will indeed show them in separate trend graphs. This component can be used for any service (doesn't have to be an enhanced service).
