PDFs
You can use the GetClusterFullThreshold method to view the stages set for cluster fullness levels. This method returns all fullness metrics for the cluster.
|
When a cluster reaches the Error stage of block cluster fullness, the maximum IOPS on all volumes are reduced linearly to the volume minimum IOPS as the cluster approaches the Critical stage. This helps prevent the cluster from reaching the Critical stage of block cluster fullness. |
Parameters
This method has no input parameters.
Return values
This method has the following return values:
| Name | Description | Type |
|---|---|---|
blockFullness |
The current computed level of block fullness of the cluster.
|
string |
fullness |
Reflects the highest level of fullness between "blockFullness" and "metadataFullness". |
string |
maxMetadataOverProvisionFactor |
A value representative of the number of times metadata space can be over provisioned relative to the amount of space available. For example, if there was enough metadata space to store 100 TiB of volumes and this number was set to 5, then 500 TiB worth of volumes could be created. |
integer |
metadataFullness |
The current computed level of metadata fullness of the cluster.
|
string |
sliceReserveUsedThresholdPct |
Error condition. A system alert is triggered if the reserved slice utilization is greater than this value. |
integer |
stage2AwareThreshold |
Awareness condition. The value that is set for the stage 2 cluster threshold level. |
integer |
stage2BlockThresholdBytes |
The number of bytes being used by the cluster at which a stage 2 condition will exist. |
integer |
stage2MetadataThresholdBytes |
The number of metadata bytes being used by the cluster at which a stage 2 fullness condition will exist. |
|
stage3BlockThresholdBytes |
The number of storage bytes being used by the cluster at which a stage 3 fullness condition will exist. |
integer |
stage3BlockThresholdPercent |
The percent value set for stage 3. At this percent full, a warning is posted in the Alerts log. |
integer |
stage3LowThreshold |
Error condition. The threshold at which a system alert is created due to low capacity on a cluster. |
integer |
stage3MetadataThresholdBytes |
The number of metadata bytes used by the cluster at which a stage 3 fullness condition will exist. |
integer |
stage3MetadataThresholdPercent |
The percent value set for stage3 of metadata fullness. At this percent full, a warning will be posted in the Alerts log. |
integer |
stage4BlockThresholdBytes |
The number of storage bytes being used by the cluster at which a stage 4 fullness condition will exist. |
integer |
stage4CriticalThreshold |
Error condition. The threshold at which a system alert is created to warn about critically low capacity on a cluster. |
integer |
stage4MetadataThresholdBytes |
The number of metadata bytes used by the cluster at which a stage 4 fullness condition will exist. |
integer |
stage5BlockThresholdBytes |
The number of storage bytes used by the cluster at which a stage 5 fullness condition will exist. |
integer |
stage5MetadataThresholdBytes |
The number of metadata bytes used by the cluster at which a stage 5 fullness condition will exist. |
integer |
sumTotalClusterBytes |
The physical capacity of the cluster, measured in bytes. |
integer |
sumTotalMetadataClusterBytes |
The total amount of space that can be used to store metadata. |
integer |
sumUsedClusterBytes |
The number of storage bytes used on the cluster. |
integer |
sumUsedMetadataClusterBytes |
The amount of space used on volume drives to store metadata. |
integer |
