This table shows the visualizations that you can add to your dashboards. For each visualization, the table shows:
- The series that the visualization contains.
- Which of the source's signals gives the information displayed by the visualization.
- Which premade dashboards contain the visualization.
- What filtering options are available for the visualization.
- Some visualizations can be filtered to show information for a single node a time. Try adding multiple copies of these aggregations to your dashboards, filtering each one to show information about a different HCP node. For example, this dashboard includes multiple HTTP Connections visualizations, one for each node in an 8-node HCP system:
- Some pie chart visualizations, such as Objects By Tenant, show data for the most-recent point in time. Others, such as Operations Breakdown, show cumulative data.
- The filtering options for some visualizations are determined by the data that HCM has collected. For example, if no DELETE requests have occurred on your HCP system, you cannot filter the Operations Breakdown visualization to show information about such requests.
- For visualizations with median series, the median values presented are approximations that are calculated using the t-Digest algorithm each time the visualization is loaded. As a result, median values might differ slightly each time you view a visualization.

| Back-end Network I/O | Shows data transfer rate over the HCP system's back-end network in bytes per second and the back-end limit.
