   The tab shows the Select a Template for your Custom page window or the default page if a default page is already set.

8. When you are ready to save the page, complete these steps:
   1. In the Page Name field, enter name for the page.

The large number of data series can make the page readability or performance unusable. The advisable limit for this chart is 50 data series. Adding specific values helps to narrow the data within recommended limits and results in a better user experience.

   Option	Description
   Retrieve latest resource Metric Types	Click to refresh metric types. If there is change in the metric type or metric when any agent patch is applied, you need to refresh the metric types. The interval between two refreshes is restricted to 15 minutes. If you click Retrieve latest resource Metric Types within 15 minutes of previous refresh, then following message is displayed: Metadata cache was refreshed recently. Please wait for time_remaining minute(s) to reload it. When the metadata is loading a loading image is displayed. When the metadata is loaded, the following message is displayed: Metadata Cache reloaded successfully. If the metadata refresh takes more than 30 seconds, then the following message is displayed: Reloading of Metadata cache might take some more time. Do you want to wait until it is done? You can click Ok or Cancel.
   View Dashboard	Click to view the data in the dashboard. Important: The limit for the number of rows that are returned per data definition is 11,000 rows. By default, latest data is displayed when the limit is crossed. For high volume of data, entire data for selected time interval is not displayed. For example, if you select to view last 24 hours of data for high volume data source, then only last 6 hours of data might be displayed if the 11000 rows limit is reached. If in a chart data series exceed 50, then the following message displayed in the widget: This chart cannot be loaded because the number of data series (such as lines on a graph) exceeds 50. The number of data series is currently current_data_series. You can reduce the number by selecting fewer metrics or resources instances, or by refining the Conditions per Metric. For more information, see Defining widget properties: for Cloud APM - http://ibm.biz/widgetprops and for Cloud APM Private - http://ibm.biz/widgetprops-private If a chart is taking more than 30 seconds to load, then the following message is displayed in the widget: This chart took too long to load because of a large amount of data, long network latency, or connectivity issue. Reduce the number of Resource Instances or refine the Conditions per Metric to narrow down the data.
