Email CPU de MySQL


6clop20

Recommended Posts

Bonjour,

Mon serveur n'arrete pas de m'envoyer des mail pour m'informer du changement de statut du CPU de Mysql (un max de chez max !!!).

Le CPU de Mysql est effectivement haut par moment (100%) (parfois meme sans que presque personne ne soit sur le site).

Je peux surement ameliorer les requetes mais ça me parait quand meme etrange que le CPU soit si haut alors que personne ou presque n'est sur le site.

J'ai activer le log pour les slow queries. le resultat depend evidement du parametre long_query_time. Pour une valeur par exemple de long_query_time = 3 le log est vide.

Je n'ai pas modifier les parametres par defaut de my.cnf. Puis je le soulager le CPU mysql en modifiant les parametres de base (key_buffer=16M, .....) ?

PS : Peut on modifier les parametres pour l'envoi des email ça commence a me gonfler !!!

Si dessous le dernier rapport par email, est-ce que vous voyez dessus qq chose d'anormal ?

MERCI

Le paramètre de santé du serveur "Services > Utilisation du CPU de MySQL" a changé son statut de "green" à "red".
