Probleme de Mémoire et de iowait (pb configuration ?)

[wick]

Bonjour,

Je possède un serveur 4 go debian uniquement ssh.
Je monitor 2 vcenter qui me donne mes hôtes après.

Number of hosts (enabled/disabled/templates)	217	142 / 0 / 75
Number of items (enabled/disabled/not supported)	5922	5778 / 0 / 144
Number of triggers (enabled/disabled [problem/ok])	90	90 / 0 [2 / 88]
Number of users (online)	2	1

Voila les détails mais je me retrouve avec un problème ma mémoire se vide tout le temps très rapidement.
voir pièce jointe

Sachant que j'ai ces problèmes aussi qui apparaissent.
Less than 25% free in the history cache
Zabbix history syncer processes more than 75% busy
Zabbix server Zabbix agent on Zabbix server is unreachable for 5 minutes
Lack of available memory on server Zabbix server

Je pense avoir mal configurer mon serveur alors voila mon fichier de configuration de mon serveur:
