💡 Hint

Common Mistakes

Using 'SystemCause' for user maintenance is incorrect.

Setting 'online' to true marks the agent online.

Use OfflineCause.UserCause to specify a user-defined offline reason, then set offline to true.

5fill in blank

hard

Fill all three blanks to create a map of agent names to their offline status if they are offline.

Jenkins

def offlineAgents = agents.collectEntries { agent ->
    [(agent.[1]()): agent.is[2]() [3] true]
}

💡 Hint

Common Mistakes

Using 'isOnline' instead of 'Offline' reverses the logic.

Using '=' instead of '==' causes syntax errors.

Use getName() to get the agent's name, check if it is Offline with isOffline(), and compare with == true.
