ISSUE TYPE

• Bug Report

COMPONENT NAME

SSVM

CLOUDSTACK VERSION

4.18

CONFIGURATION

OS / ENVIRONMENT

SUMMARY

CloudStack provides a global configuration to control the Console proxy capacity scan interval, the same is expected for Secondary storage VM but it is currently hard coded.

STEPS TO REPRODUCE

EXPECTED RESULTS

A global configuration like 'secstorage.capacityscan.interval' should be present in global configurations/settings. 
The time interval(in millisecond) to scan whether or not system needs more Secondary Storage VM to ensure minimal standby capacity

ACTUAL RESULTS

Global configuration to control the secondary storage VM capacity scan interval is missing in global configurations/settings.

I did not see "secstorage.capacityscan.interval" definition in the git history too, but MS code is looking for this param and setting default value if not present. This could be an old bug and we are living with it. We can add this setting now, since for CPVM it is already there.
