====== Graphite ======


//à compléter//


D'après les articles suivants, il problème viendrait de la configuration de la rétention ou de la fréquence à laquelle Centreon envoie les données à Graphite.\\

===== Rétention =====

2020-04-27 : J'ai ajusté la rétention (fichier /etc/carbon/storage-schemas.conf) en reprenant les paramètres du serveur de prod snc1ssupt002.

<code>
# edit 20200427 by d.loussouarn according to prod server snc1ssupt002 parameters
#[default_1min_for_1day]
#pattern = .*
#retentions = 60s:1d

# edit 20200427 by d.loussouarn according to prod server snc1ssupt002 parameters
[default_5min_for_30days_and archive]
pattern = .*
retentions = 300s:30d,30m:1y
