Feature request - Display worker names in the Dask web UI #4878
Description
@mrocklin recommended I raise this here. I asked on stackoverflow whether it is possible to display the worker names in the Dask web UI. As of right now, the workers are only listed by their IP addresses, not the names given to them, despite assigning names during their creation. Copied from my stackoverflow question (https://stackoverflow.com/questions/56299817/possible-to-display-worker-names-in-dask-web-ui/56418241#56418241):
When I create the workers (in a Python script), I do set the name:
import dask
import dask.dataframe as dd
from dask.distributed import Client as Dask_Client
from distributed import Worker
dask_client = Dask_Client('192.168.0.162:8786')
loop = IOLoop.current()
t = threading.Thread(target=loop.start, daemon=True)
t.start()
w = Worker('tcp://192.168.0.162:8786', loop=loop, name=socket.gethostname())
w.start()
And the worker name does appear when I run print(json.dumps(dask_client.scheduler_info(), sort_keys=True, indent=4)) -- excerpt below:
"tcp://192.168.0.198:39619": {
"host": "192.168.0.198",
"id": "alana1",
"last_seen": 1558707665.9223647,
"local_directory": "[omitted]",
"memory_limit": 8243511296,
"metrics": {
"cpu": 4.0,
"executing": 0,
"in_flight": 0,
"in_memory": 330,
"memory": 245129216,
"num_fds": 26,
"read_bytes": 3020.000227124918,
"ready": 0,
"time": 1558707665.9237077,
"write_bytes": 3484.3077504469734
},
"name": "alana1",
"ncores": 4,
"resources": {},
"services": {
"bokeh": 37993,
"nanny": 35817
},
"type": "Worker"
In the above example, I was hoping the name "alana1" would appear in the Dask web UI instead of what does appear: "tcp://192.168.0.198:39619"
