HeartBeats Failed

[Ashok]

@rajanprabu Very similar to what happened to me today.

-> Login (Generate session) @ 7AM - OK
-> When the cron started Websocket at 9.15 AM, the token got expired
-> Then I generated new token at 11:12 and started websocket streaming again - OK
-> But the streaming ended at 14:09 got stopped - I did not check the heartbeat, but probably that is the reason

Looks like the token i getting expired after sometime. say 2.5 hrs by estimate.

I raised this with @Bhaveshsjain @admin today morning . lets wait for the analysis.

PS: All my jobs are scheduled in a scheduler

Hi @Ashok @rajanprabu , we are reviewing this.

[admin]

@rajanprabu @Ashok We have connected the websocket today morning and till now it's working fine. If we get a disconnection before 3.30, will identify and resolve the issue.

I have tested today and I had the same error. Please find the test script below. Im using threaded=True

from smartapi import WebSocket 
import json
import datetime
import time

with open('AB/ab_user.json') as f:
    data = json.load(f)
client_code = data['client_code']

with open('AB/ab_tokens.json') as f:
    data = json.load(f)
feed_token = str(data['feedToken'])

token = "nse_cm|3456&nse_cm|7229&nse_cm|1594&nse_cm|3787&nse_cm|1330&nse_cm|10999&nse_cm|4717&nse_cm|13538&nse_cm|694&nse_cm|2031&nse_cm|2475&nse_cm|1394&nse_cm|11536&nse_cm|20374&nse_cm|1333&nse_cm|881&nse_cm|467&nse_cm|1348&nse_cm|10604&nse_cm|547&nse_cm|3506&nse_cm|4963&nse_cm|1660&nse_cm|17963&nse_cm|910&nse_cm|11532&nse_cm|526&nse_cm|3351&nse_cm|236&nse_cm|14977&nse_cm|21808&nse_cm|1232&nse_cm|1624&nse_cm|11723&nse_cm|5900&nse_cm|10940&nse_cm|3045&nse_cm|11287&nse_cm|11630&nse_cm|5258&nse_cm|11483&nse_cm|1922&nse_cm|3103&nse_cm|1363&nse_cm|2885&nse_cm|16675&nse_cm|317&nse_cm|15083&nse_cm|3499"

ss = WebSocket(feed_token, client_code)

def on_tick(ws, tick):
    print("Ticks: {}".format(tick))
   
def on_connect(ws, response):
    ws.send_request(token)

def on_close(ws, code, reason):
    ws.stop()

# Assign the callbacks.
ss.on_ticks = on_tick
ss.on_connect = on_connect
ss.on_close = on_close

ss.connect(threaded=True)

while True:
    pass

@Ashok was it running ok for you today ?? No HeartBeats Failed message ?

[Ashok]

@rajanprabu my websocket worked just fine today no failures. I was seeing tick data till 15.30.
But I forgot to log the heartbeat message to see if there are any failures.
PS: I am not using threaded ticker

[rajanprabu]

@Ashok Im also wondering if that is the root cause of the problem. But in my code I have a streamer class which emits the ticks. This I run in one thread and other things that I do in parallel using threads. This functionality is crucial.

I hope @admin and team had a look at it.

[admin]

Hi @rajanprabu , Hope your issue is resolved. If not, please share your contact details on api@angelbroking.com

@admin

I have tested without running them on threads separate threads. It went well today.

all my troubles appear when I use

ss.connect(threaded=True)

I also think this is the limitation on in unix based systems. I have modified the websocket.py to have reactor.run(installSignalHandlers=False) even one doesnt use the threaded=True.

In case if this helps anyone.

@rajanprabu hi i want data like this can you give me code?

[rajanprabu]

@gkmeena

Which code ?

@rajanprabu @admin
I am getting the heartbeat failed message.
I am wondering how do you re-establish the connection?
Also even after the program has ended the heartbeat failed message keeps popping up.

[admin]

Hi @PandaTrade we will soon our web socket code we will keep you updated on this.

[rajanprabu]

@PandaTrade said in HeartBeats Failed:

Also even after the program has ended the heartbeat failed message keeps popping up.

Thats mainly because Heartbeart connection is running in separate thread. I have a parallel script running to check if there is any HB failure message. Once it find it will stop and restart the script. Of course this can be a issue if you use indicators using past data.

[PandaTrade]

hi @admin
have you fixed your Tickdata web socket code?
To me it looks like working. Just want to confirm what are the fixes that you have done?

[rajanprabu]

@PandaTrade

They released a new SDK.. But yet to try it.. will try in the evening with MCX data.

[PandaTrade]

@rajanprabu btw how do you update your sdk that you had downloaded already..
Could you point me to it.

[PandaTrade]

@PandaTrade pip install websocket-client
i guess this should do it

[admin]

HI @PandaTrade uninstall and install again.
