Sis-Check

Checks the dedup operations (stale fingerprint, running time).

Usage

$ check_netapp_pro.pl Sis -H <host> [--metric=...] [ ... ] [--help]

Description

This plugin checks a volumes stale-fingerprint-percentage and the run-time of the last successfull operation.

(Advanced) Single-Instance Storage - short name (A)SIS - is the original name for NetApps deduplication technology. A high stale-fingerprint-percentage may indicate an issue with the background-processes responsible for deduplication.

Consider using -v for inspection, if you are not satisfied with the result.

Simple Examples

[S1] ./check_netapp_pro.pl Sis -H filer

Check the stale-fingerprint-percentage on all volumes using the default thresholds.

[S2] ./check_netapp_pro.pl Sis -H filer --metric=stale-fingerprint-percentage

Same as above, but explicitly naming the metric.

[S3] ./check_netapp_pro.pl Sis -H filer -w 20 -c 80

Check the stale-fingerprint-percentage on all volumes, warn if over 20% and send a critical alarm if over 80%.

[S4] ./check_netapp_pro.pl Sis -H filer --metric=run-time

Check the run-time if the last successful operation on all volumes using the default thresholds.
