Implementing heartbeat in stomp.py

I am seeing behavior in our stomp.py client (listener only) where after some idle time of not receiving messages the AMQ broker seems to drop the client i.e. looking at the AMQ management console shows zero consumers. The odd thing is the on_disconnected handler of the client never gets called and we have a health check on the client service that checks the connection is_connected(), however it still returns true.

Based on my understanding/research (please correct if any of this is false) this is due to the broker trying to clean-up resources it perceives as inactive. Also based on my research "heartbeating" can be used to avoid this perception on the broker.

I know how to send the heartbeat header from the client and how to check the response from the server/broker (as far as what it expects) in on_connected but my question is how do I send the actual heartbeat from the client to the server/broker? Do I need to send a message on the queue I am listening to? If so how do I send a "heartbeat message" and not have to adjust message handling code in my listeners? Do I send it without a body? Also does the broker need to be configured to accept heartbeats? and If it is not configured would declaring and sending them from the client still result in the broker disconnecting the client?

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
