GET /Trends using RESTfull EWS Gateway

[petri_greenwave]

Hi All,

We have successfully pulled data from some logs in a test environment but now need to go into this a bit deeper.

I know the GET/Trends is not supported in SoapEwsRestProvider but this is exactly what we need to do next. We want to get a list of trend logs in the system.

Apart from the GET/Trends which is not supported, is there any other way we can do this? Currently we run a query in SQL to get all the trends but then manually have to add them to the code.

Also will future versions support this? Where is the limitation?

Petri,

The RESTful EWS Gateway API was designed in a provider agnostic manner.  As a result, it was known that not all Providers would be able to support all methods.

The limitation for the SoapEwsRestProvider is that it uses EWS under the covers and EWS doesn't allow a way to "get all Trend Logs in a system" in one call.  The only workaround is to browse the object tree yourself.  As you can imagine this could be a very chatty endeavor and that is why it wasn't considered as a workaround for the provider.  In contrast, the MongooseEWsRestProvider has direct DB access to its data source so it can easily support this method.

Current development on a native SBO provider should alleviate this restriction.  This will of course be a different provider, but it will use the exact same API.
