Viewing Component Monitoring

Component monitoring displays some component metrics. You can determine the health status of your services based on these metrics. You can customize monitoring metrics. For details, see Configuring Custom Metric.

Configure performance management probes to collect more service metrics.
If you have configured performance management, click go to Application Performance Management (APM) to view more service metrics.

Prerequisites

You have created an application. For details, see Creating an Application.
You have created a component. For details, see Creating a Component.

Procedure

Log in to CAE.
Choose Component Monitoring.
Use the three drop-down lists to select components, instances, and monitoring metrics to view component monitoring information.

You can select multiple components from the drop-down list to view their statuses at the same time. If multiple components are selected, you cannot view the statuses by instance or custom metric.
Figure 1 Multi-component monitoring

You can view uplink and downlink speeds, uplink and downlink rates, CPU and memory usage, and custom metrics. For details, see Table 1.

**Table 1** Component monitoring information
Parameter	Description
Uplink Speeds (BPS)	Outbound traffic speed of a measured object
Downlink Speeds (BPS)	Inbound traffic speed of a measured object
Uplink rate (PPS)	Number of data packets sent by a NIC per second
Downlink rate (PPS)	Number of data packets received by a NIC per second
CPU usage	CPU usage of an instance
Memory usage	Memory usage of an instance
File system read rate	Number of bytes read from the file system per unit time
File system write rate	Number of bytes written to the file system per unit time
Custom metric	Monitoring dimension configured in Configuring Custom Metric

By default, Uplink Speeds (BPS), Downlink Speeds (BPS), CPU usage, and Memory usage are displayed. Select or deselect metrics from the drop-down list as required.
