Measures reported by NetCluAggrSpceTest
For an aggregate to perform effectively, there must be adequate free space in the aggregate. Periodical monitoring of the aggregates for the space usage of each of the aggregates is mandatory to identify probable space contentions which may indirectly slowdown the performance of the aggregates. This test auto-discovers the aggregates in the NetApp Cluster and reports the space utilization of each aggregate.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Total_space |
Indicates the total size of this aggregate. |
GB |
The size of this aggregate excludes the WAFL reserve and the aggregate snapshot reserve. This measure will report a value of 0 if the state of the aggregate is Restricted or Offline. |
| Available_space |
Indicates the amount of space that is currently available for use in this aggregate. |
GB |
A very low value for this measure indicates that the aggeragate is currently running out of space.
|
| Max_used_space |
Indicates the maximum amount of space that is used in this aggregate since the start of the NetApp Cluster. |
GB |
If the value of this measure is close to that of the Total space measure, it indicates potential space crunch in the aggregate. Administrators may increase the size of the aggregate so that the space utilization of the aggregate is optimal. |
| Per_max_used_space |
Indicates the maximum percentage of space that is used in this aggregate since the start of the NetApp Cluster. |
Percent |
A value close to 100 for this measure is a cause for concern. |
