I've been exploring if the REST API for the Storm UI could be used to extract detailed info about the topology configuration (locations of bolts). http://storm.apache.org/releases/1.0.1/STORM-UI-REST-API.html is the source doucmentation. We are running version 1.0.1 of Storm.
This shows the summary of the topology, as expected
http://0.0.0.0:9099/api/v1/topology/summary
Where "0.0.0.0" is a placeholder for our server.
In the above summary, the topology ID is given as "sdp-acs-cit-why-12500-why-12500-cit-why-cit-service-WHY_TOPOLOGY-1-1500659867".
That is what I would expect. However, this does not work well:
http://0.0.0.0:9099/api/v1/topology-workers:sdp-acs-cit-why-12500-why-12500-cit-why-cit-service-WHY_TOPOLOGY-1-1500659867
Nor does the route /topology:id with the above ID.
Anyone ever got these to work?
The error message says: NotAliveException(msg::sdp-acs-cit-why-12500-why-12500-cit-why-cit-service-WHY_TOPOLOGY-1-1500659867)
That makes me wonder if Storm is misconfigured somehow. Storm operates as expected as far as running the topology goes. It does what we want.
you should do like this
http://host:port/api/v1/topology/id
the id is sdp-acs-cit-why-12500-why-12500-cit-why-cit-service-WHY_TOPOLOGY-1-1500659867
