The improved Web Insight feature is augmented and provides visibility into detailed metrics for web applications, clients, and NetScaler instances. This improved Web Insight enables you to evaluate and visualize the complete application from the perspectives of performance and usage together. As an administrator, you can view Web Insight for:
In each metric, you can view the top 5 results. You can click to drill down further to analyze the issue and take troubleshooting actions faster.
In some scenarios, NetScaler might not be able to calculate the RTT values for some transactions. For such transactions, NetScaler ADM displays the RTT values as
-
NA – Displays when the ADC instance cannot calculate the RTT.
-
< 1ms – Displays when the ADC instance calculates the RTT in decimals between 0 ms and 1 ms. For example, 0.22 ms.
For example, consider that you want to analyze the server network latency for 1-month time duration and take decision whether to scale up or scale down the production environment. To analyze this:
-
Select Last 1 Month from the list and from the Applications tab, scroll down to Servers, and click a server.
The metrics details for the selected server are displayed.
-
Select the Server Network Latency tab to analyze the latency.
The average latency indicates 10.01 s and from the graph, you can analyze that the server network latency for the last 1 month seems to be high. As an administrator, you can take decision to scale up the production environment.
