Grafana dashboards overview

The Grafana dashboards show metrics about the operation and efficiency of ObjectScale.

ObjectScale contains predefined dashboards that visualize the collected metrics. Some of the metrics are shown in the UI, on the main ObjectScale Dashboard and the object store Dashboard pages. Administrators can inspect the reported data in more detail on the Grafana dashboards. Administrators can identify developing storage and memory problems by monitoring the dashboards. The dashboards also help identify inefficiencies, and provide a way to diagnose problems.

ObjectScale metrics dashboards

NOTE:Cluster-Admin privilege is required to access ObjectScale metrics.

The predefined dashboards for an ObjectScale instance are:

Table 1. ObjectScale instance dashboards
Dashboard Description

Capacity - Overview

Monitors the current and past capacity of each object store in the ObjectScale instance.

Capacity Utilization: Space Reclamation

Monitors the total garbage collection and capacity reclaimed from garbage collection, current and historical.

Capacity Utilization: Used Capacity

Monitors the total, used, and offline capacity data, current and historical.

Capacity Utilization: User Data

Monitors the user data, current and historical.
