Le site suivant est une très bonne approche de création de templates : http://wiki.monitoring-fr.org/nagios/addons/pnp/creation-template-graph

affichage de graphs cpu, mémoire et nombre de process

L'exemple suivant correspond à un des exemples de scripts perls de ce wiki. Le script renvoie, pour trois processus, la consommation mémoire, cpu et le nombre de process trouvé. Voici un exemple de ce qui est renvoyé à nagios :

Status Ok|cpu_sasexe=11 mem_sasexe=5545918464 nb_proc_sasexe=40 cpu_sasauth=0 mem_sasauth=13516800 nb_proc_sasauth=3 cpu_elssrv=0 mem_elssrv=107380736 nb_proc_elssrv=37

Le template va afficher un graphe cpu, un mémoire et un nombre de process. Sur chaque graphe, on va afficher une ligne par process (screenshot à la fin).
