Up until now aggregates and volumes could be monitored in order to determine their disk usage. The Usage
check was designed for this purpose and can be easily configured to fit your needs. However, there was no way of predicting when an aggregate would reach a critical level, or in other words, how many days it would take for an aggregate to reach a maximum usage of 100%. This feature is now available with the new check UsageTrend
. This check uses two thresholds (typically number of days) and sends warnings should they be exceeded. ./check_netapp_pro.pl UsageTrend ... ‑‑lookbehind=48h ‑w 7d ‑c 3d
For instance, the configuration above sends a warning message if the trend calculated using data from the last 48 hours indicates that the aggregate reaches full usage with then next 7 days.
