Machine List

Install and Deploy Categraf

Execute the following command to complete the deployment of Categraf. Note that you need to set the value of N9E_ADDR to the actual IP and port where the Nightingale service is deployed.

N9E_GID=32 N9E_ADDR="127.0.0.1:17000" bash -c "$(curl -L https://download.flashcat.cloud/uPic/install_categraf.sh)"

Note: For enterprise edition Categraf deployment solutions, please refer to the enterprise deployment manual.

Machine List Display

The machine list extracts machine ident information from monitoring data and displays it on the machine list page. If the collector is Categraf and the heartbeat switch is enabled, the machine list will display the machine’s metadata (memory, CPU, time offset, core count, operating system, CPU architecture, heartbeat time, source IP, etc.), essentially functioning as a simple CMDB page.

The page can be scrolled horizontally for viewing and can display a visible table header as needed.

Machine Tags

Tags essentially add a labelname and labelvalue. In the machine list, you can filter servers across business groups using tags. The tags applied to machines will also be automatically appended to the time-series metrics collected from the machines.

Binding Tags

Machine List —> Select Server —> Click “Bind Tags” at the top right

In the Bind Tags popup, enter tags in the format key=value. Use spaces or Enter to separate multiple tags, and tag keys cannot be the same.

After binding tags, a labelname and labelvalue will be added to the server. You can also filter servers across business groups using these tags in the machine list.

Tags will be automatically appended to the time-series metrics collected from the machine.

Unbinding Tags

Machine List —> Select Server —> Click “Unbind Tags” at the top right

In the Unbind Tags popup, select the tags to unbind

Tags will be automatically deleted after unbinding

Assigning Machines to Business Groups

Assign business groups to machines on the page

Infrastructure —> Machine List —> Business Groups, check the servers to modify the business group (multiple selections are allowed), and select “Modify Business Group” at the top right to assign machines to a business group.

You can also use the “Modify Business Group” option in the monitoring objects section to batch assign business groups.

Assign business groups during Categraf deployment

If you know which business group to assign the machine to during Categraf deployment, you can set a parameter to automatically assign the machine to a specific business group. This eliminates the need to assign the business group again on the page. Use the N9E_GID parameter, where N9E_GID is the business group ID in Nightingale, which can be obtained from the business group management page.

For example, if you want to assign the machine deployed with Categraf directly to the “0_Demo” business group, set N9E_GID to 32 and execute the following command.

N9E_GID=32 N9E_ADDR="127.0.0.1:17000" bash -c "$(curl -L https://download.flashcat.cloud/uPic/install_categraf.sh)"
