alert command

Purpose

Sets, removes, and lists all the alerts for a cluster and storage pool.

Syntax

To set the alert:

alert -set [-clustername ClusterName] [-spname StoragePool] [-type {threshold | overcommit}] -value Value

To unset the alert:

alert -unset [-clustername ClusterName] [-spname StoragePool] [-type {threshold | overcommit}]

To list all the alerts:

alert -list [-clustername ClusterName] [-spname StoragePool] [-type {threshold | overcommit}] [-fmt Delimiter [-header]]

Description

The alert command sets, removes, and lists all alerts for a cluster and storage pool. If the -type flag is included, this command performs the action based on the specified type of alert. The value of the -type flag can be either threshold for free space or overcommit for the overcommit space. On set or unset operations, the default value for the -type flag is threshold. If the -type flag is not specified, all the alerts are listed. The -value flag is specified in percentages.

Flags

Flag name	Description
-clustername	Specifies the cluster name.
-fmt	Separates the output with a user-specified delimiter character.
-header	Specifies the display field names in the formatted listing output.
-list	Lists alerts.
-set	Sets an alert.
-spname	Specifies the storage pool name.
-type	Specifies the type of alert. The type of alert is either threshold for pool free space or overcommit for pool overcommit space. For set or unset operations, the default value is threshold. If the type of alert is not specified when you perform the list operation, all the alerts are listed.
-unset	Removes an alert.
-value	Specifies the value of the alert in percentage.

Examples

To list alerts within the storage pool, type the following command:

alert -list -clustername newcluster -spname sp

The system displays the following output:

PoolName:          sp
PoolID:            00000000097E5568000000004FC89343
ThresholdPercent:  80
OvercommitPercent: 20

To set an alert on free space within the storage pool, type the following command:
```
alert -set -clustername newcluster -spname sp -type threshold -value 70 
```
To set an alert on overcommit space within the storage pool, type the following command:
```
alert -set -clustername newcluster -spname sp -type overcommit -value 20 
```
