<Api_GetStoragePoolListResp>
    <storagePoolList numberOfNodes="1" poolRetentionPeriodDays="365" cloudStorageClassNumber="-1" isArchiveStorage="0" libraryVendorType="0" totalFreeSpace="0" storagePoolType="2" storageSubType="0" totalCapacity="0" wormStoragePoolFlag="0" storageType="4" reserved1="1" status="Online" statusCode="0">
        [... text omited ...]
    </storagePoolList>
</Api_GetStoragePoolListResp>

How this pull request can be tested ?

Just executing the plugin against a CommServe API when StoragePools with totalCapacity property equal to "0".

Without the fix, the return string will be:

UNKNOWN: Illegal division by zero at /usr/lib/centreon/plugins//centreon_commvault_commserve_restapi.pl line 1547.
