As AgentME mentioned in their comment, if peterwwillis had seen a server without a designated owner whose metrics were teetering into an unhealthy state, and jumped in to stabilize it, wouldn't that be praiseworthy – and clearly work, not a "hobby"? There's nothing silly or unproductive about stabilizing social/emotional situations in a work context. Indeed, your own response underscores how complicated and difficult, and often underappreciated, such work can be.
