SnapVault Monitoring in Cluster Mode

Summary

This article is about an enhancement for the following two monitoring-plugins:

• SnapMirrorMetrics-Check (Documentation for SnapMirrorMetrics )
• SnapMirrorState-Check (Documentation for SnapMirrorState )

In DataONTAP Cluster Mode the specific engine for SnapVaults has been removed and therefore, there no longer is an API. Thus, SnapVaults are nothing more than SnapMirrors of the type _vault. _In principle, this is quite practical, since numerous features have been added to the **SnapMirror **checks, which can now be used for SnapVaults as well. Maybe it would make sense to include a type based filter option. Currently, there is the option to filter by name – this can be done quite flexibly with any number of ‑‑include and ‑‑exclude switches, each of which evaluates a regular expression. Purposeful evaluation of SnapVaults, or rather SnapMirror relations of thetype vault, would require a naming convention where it is possible to unambiguously deduce the type from the name. An additional filter that is independent from the name might be useful. Relationship-type would have to be evaluated. It can be described as follows:

Specifies the type of the SnapMirror relationship. Possible values: “data_protection” , “load_sharing” , “vault” , “restore” , “transition_data_protection”

A filter such as in this example would be conceivable:

• ‑‑type=vault to check relations of the type vault only.
• ‑‑type=data_protection ‑‑type=transition_data_protection to check relations of the type data_protection or transition_data_protection only.

We value your opinion on this subject. Please write to: developer[ a t ]netapp-monitoring.info Pro Tip: In Version 3.0.13 relationship-type is already stored by cm-Getter and can be viewed with ‑‑explore: e.g. $ ./get_netapp_cm.pl -H sim -o snap-mirror ‑‑explore Existing data for object 'snap-mirror' Node:sim Instance: cluster1://hansi/snapdst (uuid n/a) current-transfer-error = n/a destination-cluster = cluster1 destination-location = cluster1://hansi/snapdst is-healthy = true lag-time = n/a last-transfer-duration = n/a last-transfer-error = n/a last-transfer-size = n/a mirror-state = snapmirrored relationship-id = n/a **relationship-type = data_protection** source-cluster = cluster1 source-location = cluster1://hansi/snapsrc unhealthy-reason = n/a Explore done - now configure your nagios ...
