The System tab differentiates between Memory and Storage data based on the
MetricType field retrieved from the device.
- Memory metrics typically represent volatile memory (RAM) utilization.
- Storage metrics represent non-volatile disk or filesystem usage (e.g., flash, SSD, HDD).
Accurate separation of memory and storage resources allows better visibility into device performance.
Important:
- Storage data is identified by the condition
isMetricType == hrStorageFixedDisk. - If a device does not return the
MetricTypevalue, its metrics cannot be correctly classified — these entries will default to the Memory table, even if they actually represent storage. - This behavior is by design, ensuring that all available data is displayed, but it may cause storage devices to appear under the Memory tab for certain models or SNMP implementations.
