List of Slaves connected to master - Hudson

Question

Is there a way to find it programatically? I need this as part of an automated run; So this would be very helpful if there is an existing remote API call which can give this.

Answer 1

You don't need to parse the HTML - most of the Hudson pages can be turned into API calls by adding URL suffix, e.g. make GET calls to:

http://hudson:8080/computer/api/json

Switch the JSON for either XML or Python if you prefer these over JSON.

If you use just the API suffix, you'll get a short generic help page on the API.

Good, +1! I thought there was something like this, but never got around searching for it. – Kresic

1 Was looking for something like that. But under terms like "jenkins environmental variables" but with no luck. – Cyanogen

Answer 2

Groovy script to get all computers:

def jenkins = Jenkins.instance
def computers = jenkins.computers

computers.each{ 
  println "${it.displayName} ${it.hostName}"
}

Cohin

looks nice! but where to get info what is "Jenkins" and why there is "instance"? Isn't it possible to write just: Jenkins.instance.computers.each{println "${it.displayName} ${it.hostName}"} ? – Preempt

yes, you can write that. it's a matter of taste / coding style. – Cohin

Answer 3

Look at http://hudson:8080/computer/

Thanks. I saw that. I can parse it and get it as part of my automated run. But wanted to know if there is more specific API for this. – Abeyta

@Aviator: Look at openjey's answer. I kept this open in a browser windows because I seemed to remember that there is an API, but never got around digging for that info. Now openjey has answered that. – Kresic

Where is the link in the UI to this? How was I suppose to know this – Goiter
