Maximum CPU Usage | Maximum CPU utilization of the AI gateway within the selected time granularity. It is used to discover CPU load peak fluctuations and locate performance surges caused by compute-intensive operations (such as complex authentication and protocol conversion). |
Number of Running Nodes | Number of normally running nodes in the AI gateway within the selected time granularity. It reflects the deployment scale and available node status. An abnormal decrease in the number of nodes may indicate a fault or scaling operation. |
New Connections from Client to Gateway Process | Number of newly established TCP connections between the client and the gateway process within the selected time granularity. It is used to observe the frequency of connection establishment over a short period and determine the activity level of client connections. |
Active Connections from Client to Gateway Process | Number of TCP connections in an active communication state between the client and the gateway process within the selected time granularity. It reflects the effective connection load currently borne by the gateway. |
Inactive Connections from Client to Gateway Process | Number of TCP connections that are established but have no active communication between the client and the gateway process within the selected time granularity. It assists in judging the idle status of connection resources. An excessive number may indicate that the connection reclamation / management mechanism needs optimization. |
Concurrent Connections from Client to Gateway Process | Total number of TCP connections that exist simultaneously between the client and the gateway process within the selected time granularity (including active and inactive). It directly reflects the concurrent connection pressure on the gateway and is a key metric for evaluating the connection capacity of the gateway. |
Inbound Traffic from Client to Gateway Process | Total data volume sent from the client to the gateway process within the selected time granularity. |
Outbound Traffic from Gateway Process to Client | Total data volume sent from the gateway process to the client within the selected time granularity. |
Inbound Bandwidth from Client to Gateway Process | Average bandwidth usage from the client to the gateway process within the selected time granularity (traffic transmission rate per unit time). It is used to evaluate the bandwidth pressure from the client to the gateway and avoid connection / transmission delays caused by bandwidth bottlenecks. |
Outbound Bandwidth from Gateway Process to Client | Average bandwidth usage from the gateway process to the client within the selected time granularity (traffic transmission rate per unit time). It is used in conjunction with "inbound bandwidth" to analyze the outbound bandwidth load of the gateway and prevent bandwidth bottlenecks from affecting response transmission. |
