The Resource Center displays two types of resources: an instance list and a process list.
Prerequisites
You have enabled ECS Insight for your application.
Try in Playground
Alibaba Cloud Playground provides a demo environment where you can experience the main features of Cloud Monitor 2.0.
Go to the Playground Demo environment. The default workspace is
o11y-demo-cn-hangzhou.In the navigation bar, click ECS Insight. Or, in the Application Center, click ECS Insight.
In the ECS Insight navigation bar, click Overview.
Choose . Click an Instance ID and then click Instance Overview or Associated Topology. The instance overview and associated topology pages are displayed.
Instance list
In ECS Insight, go to Resource Center > Instance List to view the list of ECS instances.
Query conditions
You can set query conditions to filter the information. This example uses two conditions:
domain = acs
type = acs.ecs.instance
Page layout
The page includes the following columns:
ECS Instance ID: The ID of the instance from which logs are collected.
ECS Instance IP: The IP address of the instance from which logs are collected.
Region: The region where the ECS instance is located.
Instance Status: The running status of the ECS instance.
Security Group: The security group to which the ECS instance belongs.
VPC: The virtual private cloud (VPC) associated with the ECS instance.
Instance overview
Click an ECS instance name to view its overview. The instance overview provides observability for a single instance. After you enable agentless metrics (CloudMonitor metrics), the system displays the infrastructure monitoring dashboard for the Elastic Compute Service (ECS) instance. This dashboard includes:
Basic resource consumption monitoring, system load monitoring, and basic network monitoring.
The GPU infrastructure monitoring section displays data only if the instance is a GPU host. Otherwise, this section is empty.
Associated topology
This section displays the upstream and downstream topology of the instance. For an ECS instance, the topology shows its relationships with upstream resources, such as the VPC, and internal components, such as network interface cards, disks, and security groups.
Dashboards
This section lists all dashboards related to the instance, such as the instance audit dashboard and the instance metric dashboard.
The instance audit dashboard displays statistics and details from system logs.
The instance metric dashboard displays advanced dashboards for host processes, host networks, and GPU monitoring.
Logstores
This section lists all Logstores in the workspace, such as those for ECS system logs, ECS host events, and security alert events. The data scope includes all ECS instances that are connected to the workspace.
Metric stores
This section lists all metric stores in the workspace, including those for ECS host infrastructure metrics, ECS host process metrics, ECS host node metrics, and GPU host infrastructure metrics. The data scope includes all ECS instances that are connected to the workspace.
Entity topology
This section displays the Alibaba Cloud observability entity topology graph. You can set multiple viewing methods and view multiple levels.
Process list
In ECS Insight, go to Resource Center > Process List to view the process list for an ECS instance. This page provides a global view for process insight and analysis on ECS instances and includes the following information:
An overview of the resource consumption of processes on an instance, including real-time comparisons and time-series analysis of CPU, memory, disk, and network usage.
A detailed list of processes on the instance, including PID, runtime, start command, and resource consumption.
Network insights for processes on the instance, including inbound and outbound network rates, inbound and outbound packet counts, and the number of connections.
Statistics on the number and status distribution of child processes and subthreads for processes on the instance.
System calls for processes on the instance, including I/O read and write rates and the number of file descriptors.
