Overview¶
On the Network > Overview page, the system combines time series distribution charts and network path lists to display detailed network traffic and data connection information between the server and client for four types of infrastructure: Host, Pod, Deployment, and Service.
- Time Series Chart: A graphical representation of trends in network metrics across different time intervals.
- Network Path List: Includes information such as client, server, TCP retransmission count, TCP connection count, TCP close count, TCP latency, sent bytes, received bytes, etc.
Network Path List¶
Displays data including client, server, send end, received bytes, TCP latency, TCP retransmission count, and more.
You can click the settings button on the right to customize the displayed columns.
Note
Changes to custom display fields need to be based on the user level and are not saved globally.
Quick Filtering¶
On the left side of the overview page, you can quickly filter data based on fields such as transmission direction, protocol, host, PID, server, and client.
Combination of Transmission Direction and Protocol
Currently supports network performance monitoring based on TCP and UDP protocols. Combined with incoming and outgoing directions, there are 6 possible combinations:
- incoming + protocol agnostic
- incoming + TCP protocol
- incoming + UDP protocol
- outgoing + protocol agnostic
- outgoing + TCP protocol
- outgoing + UDP protocol
Details Page¶
Clicking on a specific network entry in the list navigates to the details page, where you can view L4/L7 network performance monitoring data within the workspace, including the top section showing client-server transmission direction, key metric trends, and network connection analysis.
Warning
- Linux systems are currently supported only. In addition to CentOS 7.6+ and Ubuntu 16.04, other versions require a kernel version higher than 4.0.0;
- L4/L7 network viewing is supported only for infrastructure types: Pod, Deployment, and Service;
- Host network traffic data is saved by default for the last 48 hours (24 hours for Free Plan).
Network Connection Analysis¶
The Network Connection Analysis provides detailed visibility into key connection metrics such as client, server, connection direction, sent bytes, received bytes, TCP latency, and TCP retransmission count. To improve query efficiency and avoid failures due to excessive data volume, aggregation statistics by IP address are supported.
You can manage the list through the following actions:
-
Click the settings button to flexibly configure which fields are displayed in the list.
-
Keyword filtering is supported for all string-type fields.
