I have an elastic apm server version 7.17.1. There are only to Django application on the server. The APM service is using about 140MB of memory. When connecting new agents, I receive a timeout error.

sending data to APM server: Read timed out, response code is -1
If I use flask or Django or PHP, new apps are registered.
(I couldn't find logs from Go, but that APM agent failed as well.)
APM server logs did not appear relevant as the errors occurred in both instances
Check your IPS. In our env, we saw the IPS swatting down packets from Java and Go-based apps. I'm no developer, but once we got those sources white-listed, we saw the Agents information coming through :)
The pricing for Azure SignalR Service is based on Concurrent Connections.
However, I can't find the definition of a Concurrent connection.
I have an ASP.Net Core MVC Web Application. I understand that the server application connection to the Azure SignalR Service is one connection. Each client (browser) that connects to my web app is another connection. But are these considered concurrent connections? Or just open connections sitting there waiting for a message to be sent?
I'm hoping that the count of concurrent connections is a count of connections that are actively sending a message. Is that the case?
Ok so I figured out that a Concurrent connection is any connection to the SignalR Service!
I ran through the quickstart tutorial here
And then used the Azure Metric as I connected various clients to the chat room, and this is what I found:
After starting the app in debug mode, it seems the server immediately uses 5 connections. Then, as I open the url in various browser tabs, a new Client connection is established. As expected, the 16th browser tab does not establish a SignalR connection (Because I am on the Free SignalR Service tier, which has a limit of 20 connections.)
Our team is currently doing a proof of concept on Hyperledger which uses IBM Cloud Blockchain template and Cloud Foundry. We deployed our Hyperledger blockchain to https://console.bluemix.net/. We are running on Fabric 1.1 and we just followed this tutorial https://www.ibm.com/developerworks/cloud/library/cl-deploy-blockchain-starter-plan-network/index.htm to deploy our network.
We are currently encountering the following error after running the following command "cf start ": ERR Failed to make TCP connection to port 3000: connection refused ERR Timed out after 5m0s: health check never passed.
I've already set the health check timeout to 300 but still no luck. I've also checked the port 3000 it is already allowed / opened. Can someone help me with this issue? If you need more information just let me know and I'll try to provide it as much as I can. Thank you in advance.
can't communicate with my Hyperledger Fabric's First-Network...
I can query and invoke from inside CLI docker container. Works fine!
But if i want to use Postman and Json to invoke or query from a client PC, than i get an error message in the orderer log:
[grpc] Printf -> DEBU fc9 grpc: Server.Serve failed to complete security handshake from "10.xx.xx.xxx:56694": tls: oversized record received with length 21536
The docker containers are on Suse Linux Server and not on locally VM.
I can ping my server and the Orderer-Container Port is mapped as default config(7050:7050)
I don't really know where to find the right cert.pem and key.pem files on the linux server filesystem. Tried different one in Postman = Option client certificates.
Also tried to search a solution but can't find a working one.
Hyperledger Fabric Peer and Orderer nodes only support direct communication using gRPC (which is protocol buffers over HTTP/2) APIs. They do not offer an HTTP/REST interface. Postman only supports HTTP endpoints so it will not work with peer or orderer nodes. (the error you see if also likely due to the fact that postman was not using HTTPS).
If you want to attempt to use REST with the peer and orderer nodes, you might want to check out https://github.com/hyperledger/fabric-sdk-rest which aims to provide a REST server in front of Hyperledger Fabric nodes.
I have configured Bluemix Secure gateway client to connect to DB2 on AS 400 using a Windows machine. I am able to run the Db2 connection successfully from the application on Windows machine where Secure gateway client is running. But when I run the same application on Bluemix with modifying the code to depict Secure Gateway client destination details, I get 'Connection Refused' error.
I had gone through how to connect a bluemix app to on-premise db/as400? , which mentions about Secure gateway client for OS 400.
Wanted to understand how to fix the issue for 'Connection Refused' ? Do we have to use different DB2Driver/ DB2 Connect string from Bluemix? or Any other settings to be done on AS400 server?
Given that the Connection refused error is occurring between your BlueMix application and the SG Servers and no logs are being generated on the SG Client, it sounds like the issue is with a listener not being opened on the SG Servers rather than an issue between the SG Client and DB2. All listeners should come up when the SG Client initially connects to the SG Servers.
Are you able to cURL or telnet the cloud host:port provided with this particular destination? Or is this connection refusal specific to your BlueMix app? In either case, this answer will provide more direction on where to investigate further.
