Storage Monitoring

Top  Previous  Next

This article refers to two distinct types of computer data storage facilities: memory (RAM, etc.) and persistent storage (hard disk drives, optical discs, etc.).

Storage monitoring data is obtained using SNMP and WMI.

Via SNMP, hrStorageTable SNMP table is utilized to get detailed information about logical storage volumes on the host, including their types, descriptions, total and free sizes, allocation units, etc.

Via WMI, AggreGate Network Manager uses the following classes:

Win32_PerfFormattedData_PerfOS_Memory to monitor memory
Win32_LogicalDisk to monitor persistent storage.

AggreGate Network Manager comprises the following storage monitoring tools:

Storage Space (SNMP) alert
