The host monitoring feature is used to monitor the metrics of CPU, memory, disk, load, network traffic, and network packets. This topic describes the host monitoring feature and how to view host monitoring metrics.
The host monitoring feature can monitor the following metrics:
- Total CPU usage
- System CPU usage
- User CPU usage
- Usage of CPU waiting for I/O
- Total memory
- Free memory
- Used memory
- Memory in PageCache
- Memory in BufferCache
- Total disk space (bytes)
- Free disk space (bytes)
- Used disk space (bytes)
- Network traffic
- Received network traffic (bytes)
- Sent network traffic (bytes)
- Network packets
- Received packets per minute
- Sent packets per minute
- Received errors per minute
- Discarded packets per minute
- Log on to the EDAS console.
- In the left-side navigation pane, click Applications.

View host monitoring metrics
On the HOST Monitoring tab, you can view the time curves of CPU, Memory, Disk, Load, Network Traffic, and Network Packets.
- You can click the name of a metric such as cpu_sys on each monitoring panel to enable
or disable the visibility of this metric.
Note Each chart must contain at least one visible metric. Therefore, if only one metric is displayed on a monitoring panel, the metric cannot be set to invisible.
- You can click the line chart icon in the upper-right corner to view the metrics by range or compare the metrics.
- You can click the View API icon in the upper-right corner to view the detailed information about the API operations that are related to the metric.
