Is there a RESTAPI available to access OAC charts?
Summary:
Hello,
Is there a RESTApi available to access OAC charts?
Content (required):
I have a requirement to automate the health status of OAC charts (if any of the charts are broken we would like to trigger an alert). I want to develop an automation script for this using Canaries.
This would require access to the API. Is there an API that is be available for the current OAC, that I could access?
Version (include the version you are using, if applicable):
OAC v6.1
Code Snippet (add any code snippets that support your topic, if applicable):

To my knowledge there isn't a native API to check the status of a visualization. By broken I'm assuming you mean there is a Query Error.
If that is the case you could build a solution leveraging the Usage Tracking features - if you're using ADW as a source you could then build an API against the Usage Tracking table to get the status of a query.

You are right. By broken I mean a Query Error. Would the Usage Tracking feature enable me to detect the text 'Query Error' when occurs? Would this text be part of the query_blob field?

There is a field that is used to define when a query error occurs. I believe the field is on the Logical Query table, identified as SUCCESS_FLG.
To my knowledge a query error would result in SUCCESS_FLG = '3'.
As far as identifying what Project/Canvas this error occurs on I would look to the SAW_SRC_PATH field on the Logical Query table.

The field SAW_SRC_PATH in utlogical table returns null, when SUCCESS_FLG = '3'
Is there a way to find the Project/Canvas name where the error has occurred?
Thanks in advance,

That is unexpected behavior...
It may depend on how your underlying data model is being created. Are you leveraging an RPD based approach?

Yes, we are leveraging RPD based approach and seeing this. Any recommendations to correct this?

I would have to poke around your environment. My only other suggestion is to try and parse the canvas information from the Query Text/Blob.

Okay. I've actually tried parsing this info from Query Text/Blob. It does'nt seem to give the right info. I am unable to find Canvas name in these fields.
Also, what is the recommended procedure to generate the RPD ? Does it need to be re-generated when we connect to a new ADW? (in our case we have used an existing RPD with a new ADW and tenancy).
Apparently, the query, "select saw_src_path,query_blob,query_text from utlogical where success_flg=3 and saw_src_path like '%canvas%'" gives me desired results with old ADW - I have issues when connected to new ADW using same RPD.
Thanks, Chethana
