Charts and graphs summarize the values of specific StorageGRID metrics and attributes.
The Grid Manager Dashboard includes pie (doughnut) charts to summarize available storage for the grid and each site.
The Tenant Manager Dashboard includes a pie chart to show which S3 buckets or Swift containers are consuming the most storage and a pie chart to show how much of the tenant's quota has been used.
In addition, graphs that show how StorageGRID metrics and attributes change over time are available from the Nodes page and from the page.
There are four types of graphs:
- Grafana charts: Shown on the Nodes page, Grafana charts are used to plot the values of Prometheus metrics over time. For example, the tab for an Admin Node includes four Grafana charts.
Note: Grafana charts are also included on the pre-constructed dashboards available from the page. - Line graphs: Available from the Nodes page and from the page (click the chart icon
after a data value), line graphs are used to plot the values of StorageGRID attributes that have a unit value (such as NTP Frequency Offset, in ppm). The changes in the value are plotted in regular data intervals (bins) over time.
- Area graphs: Available from the Nodes page and from the page (click the chart icon after a data value), area graphs are used to plot volumetric attribute quantities, such as object counts or service load values. Area graphs are similar to line graphs, but include a light brown shading below the line. The changes in the value are plotted in regular data intervals (bins) over time.
- State graph: Available from the page (click the chart icon after a data value), state graphs are used to plot attribute values that represent distinct states such as a service state that can be online, standby, or offline. State graphs are similar to line graphs, but the transition is discontinuous; that is, the value jumps from one state value to another.
