[selenium-users] Node is disconnected with Hub

[anemuday]

Meta -

OS:
Windows 7
Selenium Version:
Selenium 3.12
Browser:
Chrome 3.12


Steps to reproduce -

All my project source code is in BitBucket and project is setup in Jenkins.
Goal is to run entire suite on a schedule time daily from Jenkins.


Hub(Linux) is running on the same Jenkins Server and Node(Windows) is
getting connected to the Hub.


But the problem is, Node is disconnected with the Hub after 1-2 days,
because of this, my scheduled jobs in Jenkins are failing most of the time.


How can i make sure the Hub and Node stay connected for longer days(say 30
/ 50 days)?


Following is the command i am using to connect Node with Hub:
java -jar -Dwebdriver.chrome.driver=chromedriver.exe
-Dwebdriver.gecko.driver=geckodriver.exe
selenium-server-standalone-3.12.0.jar -role node -nodeConfig node1.json

and following is nod1.json file content:

{
"capabilities":
[
{
"browserName": "firefox",
"maxInstances": 5,
"seleniumProtocol": "WebDriver"
},
{
"browserName": "chrome",
"maxInstances": 5,
"seleniumProtocol": "WebDriver"
},
{
"browserName": "internet explorer",
"maxInstances": 1,
"seleniumProtocol": "WebDriver"
}
],
"proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
"port": 17946,
"register": true,
"registerCycle": 5000,
"timeout":432000,
"hub": "http://jenkins.abc.com:4444",
"nodePolling": 5000,
"role": "node"
}

Can someone help me what i am missing? How can i make the Node and Hub
connected?

Have you ruled out network flakiness between the Hub and the node machines ?
If there's a network glitch then the connection could be severed.

How can i make the Node and Hub connected?

The easiest way of doing this would be to build a self healing mechanism
within the Grid.

Sometime back I created a blog post that shows how to go about doing this:

Please see if that helps.

Thanks Krishnan for your reply.

I am hoping there is no network glitch in this. Is there a way we can
monitor this network flakiness between hub and node?

Is there any other ways or configurations i am missing in my case? I yet to
understand the info you shared in the thread.

Thanks & Regards,
Uday

Not sure what additional information you are looking for. I have shared
what I have as info, in terms of how to ensure that the Hub and the node
stay always connected by building a self healing mechanism. There are no
out of the box configurations etc., AFAIK, that can do this.


Thanks & Regards
