Dans un cluster PowerHA, il peut être utile de suivre l'activité Heartbeat des différents réseaux.
Pour cela, on utilise la commande 'lssrc -ls topsvcs' qui interroge le sous-système associé.
Cela retourne un rapport avec des indications sur les trames manquées( Missed beats)
Un exemple est donné ci-dessous :
# lssrc -ls topsvcs
