Quick groovy script to check disk-space on a subset of integration machines via the script console.

diskspace.groovy

import hudson.util.RemotingDiagnostics

def groovyScript = 'println "df -h /srv".execute().text'

def computerNamePrefix = 'integration-slave-'

for (slave in hudson.model.Hudson.instance.slaves) {
    def computer = slave.computer
    def computerName = computer.getName()

    // Only check nodes that are named like integration-agents
    if (!computerName.startsWith(computerNamePrefix)) {
        continue
    }

    println "Checking ${computerName}..."

    if (computer.isOffline()) {
        println "${computerName} Offline..."
        continue
    }

    println RemotingDiagnostics.executeGroovy(
        groovyScript,
        computer.getChannel()
    )
}
