The Index

What do you want to check?

The Index is an alphabetical ordered list of keywords which should give you an answer to the question: How can I check <keyword>?

active-iq

Active IQ, formerly known as ASUP

see ASUP

aggregate

Usage checks the used space in volumes and aggregates. Thresholds can be set in GB or percent.

AggregateState checks the aggregates-state. Alarms if they are not online (configurable).

check_netapp_scrub.pl sends an alarm if the last scrubs timestamp of an aggregate is over a certain age.

OvercommitAggr returns a list of aggregates together with their overcommitment in percent. Overcommitment is the relation between the aggregates size and the total of all its (thin provisioned) volumes sizes.

Raidstatus alarms if one of the RAIDs is degraded.

UsageTrend checks the time how long ist would last until an aggregate or volume is full, if the trend of the last 48h (configurable) would continue. Checks both bytes and inodes.

PerfAggregate checks the 'latency', 'transfer-rate' and other performance counters per aggregate. Shows details for total, read, write and other. Also averages and totals over all aggregates of the filer can be measured and monitored, which allows the monitoring of the aggregate-latency and aggretate-transfer-rate on the filer level.

SyncMirror checks the mirror-status on Metro Cluster aggregates.
