Description
The topology visualization api end point ( /api/v1/topology/TOPOLOGY-ID/visualization ) does not return correct "stats" values for "system" components __system and __acker.
See the following example correct response for a spout or bolt within a topology, shorten for brevity. Under the stats key it lists all of the instances of that component that is deployed.
{
"spout": {
...
":stats": [{
":host": "e54bb273-2a8a-4320-b23f-7c7ace52c961-10.153.0.30",
":port": 6700,
":uptime_secs": 0,
":transferred": {
...
}
}],
...
},
See the following response for the __system and __acker components. They do not correctly list any entries under the stats key.
{
"__system": {
":type": "spout",
":capacity": 0,
":latency": null,
":transferred": null,
":stats": [],
":link": "\/component.html?id=__system&topology_id=test-1-1495630798",
":inputs": []
},
"__acker": {
":type": "spout",
":capacity": 0,
":latency": null,
":transferred": null,
":stats": [],
":link": "\/component.html?id=__acker&topology_id=test-1-1495630798",
":inputs": [...]
}
