Application usage and lean period analytics (Key metrics)
As an administrator, you must ensure how the application is getting utilized. The application key metrics can help you identify the application usage. Since the traffic range to the application is unpredictable, some unusual application performance deviations might occur for a specific duration. In such scenarios, as an administrator, you might want to view and analyze such sudden spikes, and ensure if any immediate troubleshoot is required. NetScaler App Delivery and Security service provides necessary details for a specific duration (1-hour, 1-day, 1-week, and 1-month).
Navigate to Analytics > Applications, click an application, and select the Key Metrics tab. You can view the following key metrics in a graphical format:
-
Response Time
-
5xx error
-
Requests per second
-
Throughput
-
Client connections
-
Server connections
-
Data Volume
Lean period analytics
As an administrator, you might want to schedule a downtime to the web application for a planned upgrade. A typical downtime for an application can be 1-hour, 2-hour, or 4-hour, depending upon the requirement. The Key Metrics tab analyzes the traffic pattern and provides suggestions to view the lean period for the application. You can select the time from the list (1-hour, 2-hour, or 4-hour) that you want to plan for the downtime. After you select the time from the list, you can analyze the traffic for metrics such as Total Requests, Throughput, and Data Volume. You can select the right time to schedule for a downtime when the application usage is less. The following example is to analyze the downtime for the 1-hour duration.
The heatmap view indicates the application usage for the selected time duration. The darker the color (blue), indicates the application usage is higher. The heatmap view also suggests the top 5 least period (1, 2, 3, 4, and 5) to plan for the application downtime.
1 – Indicates the first suggestion for Wednesday from 4 pm to 5 pm.
2 – Indicates the second suggestion for Thursday from 9 pm to 10 pm.
3 – Indicates the third suggestion for Sunday from 7 am to 8 pm.
4 – Indicates the fourth suggestion for Wednesday from 12 pm to 1 pm.
5 – Indicates the fifth suggestion for Monday from 7 am to 8 pm.
You can also select any other day and time to schedule a downtime, after analyzing the traffic for all other days.
Click See Details to view further detailed information. Click the Total Requests, Throughput, or Data Volume tab to view details for the top 5 least period and also for the other days.
