Context pages
Context pages provide specific, focused performance or status data from a narrow context, such as a single router or server. These pages are available as drill-down links or tabs from Summary dashboards.
dashboards
Dashboards are report-building pages within the CA Performance Center user interface. They appear as menu items that are accessible from the Dashboards tab. Each dashboard is a collection of views that present data from registered data sources on a single web page. The layout, views, time interval, and group context of each dashboard can be customized.
data source synchronization
Data source synchronization occurs when a data source is first registered to CA Performance Center. It involves a full database replication. CA Performance Center receives information about all managed items in that data source. This type of synchronization does not recur automatically on an ongoing basis, but you can manually initiate it if necessary.
data sources
Data sources are the supported products that provide performance and configuration data to CA Performance Center. Data source products, which perform monitoring, data collection, and data aggregation, can often function independently. However, once they are registered to an instance of CA Performance Center, they are called data sources.
domain
IP domains are logical groupings that identify data collected from different devices and networks. Monitoring by domain means that IP addresses with associated interfaces or applications that belong to separate customer networks are monitored separately. When combined with appropriate permissions, IP domains are monitored from a single console, but users view data only for the domains that they monitor.
drill down
To drill down means to navigate from one data view or dashboard in CA Performance Center to another, more detailed data view or context page. The new page displays data from the same timeframe, for the same managed item or set of items.
Dynamic Views
Dynamic views are customizable views that let you combine data from multiple managed items, or from multiple groups of items, in a single view. You can compare the data from hundreds of managed items or groups of managed items in a single chart or in multiple charts. View settings let you select display units and determine how data is plotted.
global administrator
The global administrator administers product settings for all tenants. This user account, also called the "Default Tenant administrator" because of its association with the Default Tenant, creates tenants and performs tenant configuration.
global synchronization
Global synchronization refers to the automatic reception, processing, and application of information from the data sources. Synchronization occurs every 5 minutes and includes configuration and performance data from all registered data sources.
group
A group is a filter definition that functions as a container for managed items. Groups let you logically organize managed items in a tree structure, with each group containing subgroups or managed items. The structure is propagated to the data sources, where it enables drilldown from top-level groups into data from an increasingly narrow but related context.
menus
Menus are segments of the Dashboards tab that are used to organize dashboards by their content. By default, Administrators and Designers can customize menus and assign them to user account roles.
metric family
The metric family defines the set of values to collect and report for a given technology. The metric family selected for a view determines the values to retrieve from the database and display in that view. For a CA Infrastructure Management Data Aggregator, it determines the values to collect for devices that are associated with a monitoring profile.
MPLS
MPLS is a routing protocol designed to enhance network speed and reliability in an IP environment. MPLS edge routers place labels on packets to specify routes and packet priority. Once these routers assign the paths, less processing is required to route packets, and paths are more predictable.
Multitrend Views
Multitrend views are customizable views that let you combine trend data from multiple interfaces in a single line trend chart. You can compare the data from up to 12 interfaces in a single multitrend view.
Multiviews
Multiviews are customizable views that let you combine statistics from multiple interfaces in a single view. You can compare the data from up to 48 interfaces in a single multiview.
My Dashboards menu
The My Dashboards menu is a dashboard container that can be personalized for each operator who has a user account in CA Performance Center. Any dashboard that you customize—by moving items to different positions in the layout, for example—appears in your My Dashboards menu. Such modifications are not available to other users.
permission groups
Permission groups comprise the scope of the managed items that each user can monitor. Administrators can create custom groups of managed items, such as applications, servers, networks, routers, and interfaces, to reflect each user’s area of responsibility. When they are assigned to a user account as permissions, custom groups are called permission groups.
pingable device
A pingable device refers to a device that does not allow SNMP polling and is therefore contacted using ICMP ping tests for status and reachability statistics.
product privilege
The product privilege is a type of permission set associated with a user account. The product privilege grants user access to features in selected data sources and does not apply to CA Performance Center functionality.
projection
A projection plots the trend in future values for a selected metric, extrapolating from the metric data that is requested in the view. Projections are displayed as broken trend lines to indicate that they are based on estimated values.
reports
Reports describe the output from an exported dashboard page. Reports contain the same data and information as the associated dashboards, but they are formatted to meet the requirements of the export destination. You can print reports, send them by email, or export them in PDF format.
role
The role is a parameter assigned to a user account that controls user access to product features and dashboard pages. Based on user job functions, the role grants administrative access to product configuration. In a well-planned deployment, roles let users access dashboards that they require to perform their duties and restrict access to features that they do not require.
shared dashboard
A shared dashboard is a page that is included in a shared menu—any menu other than the My Dashboards menu, whose contents are specific to user accounts.
site groups
Site groups are custom groups that are based on physical locations, such as a city, region, office, or campus. Typically, they contain items and subgroups of items that are grouped by location. When you add site groups to the other custom groups in your tree structure, you can build reports that are organized both geographically and logically. Site groups enable business-hour filtering of dashboard views.
SNMP profiles
SNMP profiles are definitions that contain the information necessary to enable secure queries of device MIBs using SNMP.
standard deviation
The standard deviation shows how much variation there is from the average (mean, or expected value). A low standard deviation indicates that the data points tend to be very close to the mean. High standard deviation indicates that the data points are spread out over a large range of values.
statistical data
The statistical analysis data set includes minimum, maximum, mean (average), standard deviation, and other metrics that are recalculated hourly to include the most recently collected data. This data helps to characterize past performance for selected monitored parameters, and helps to assess present performance and estimate future performance. For example, comparing current CPU utilization to a known baseline average level helps to determine whether current utilization is within a typical range. A monitored parameter that exceeds a baseline can indicate additional load on the server from a new application process, an increase in the number of users or sessions, or an increase in the amount of data being processed.
Baseline averages and other statistical data are updated hourly, averaging up to 30 “same-hour” hourly roll-up samples for each one of the preceding 30 days.
Summary context
With the Summary context setting, the available views display summary data for the current group context of the dashboard. The Summary setting does not require you to select a specific group or item. Summary views dynamically update the context when you change the context of the page.
Summary pages
Summary pages provide high-level information, such as averages from groups of managed items. Summary dashboards often provide a drilldown path to more detailed, related pages from a selected context.
system groups
System groups organize managed items and maintain separation among items from data sources registered to the same CA Performance Center instance. They are created automatically to facilitate placement of items in custom groups, provide basic sets of user account permissions, and provide report context.
tab
Tabs are the prominent links across the top of the CA Performance Center interface that let you view dashboards and open administration tools. For example, the Dashboards tab lets you select a dashboard page to view from a menu.
tenant
A tenant represents a customer environment that a managed service provider administers. Each tenant environment is independent and effectively functions as a separate instance of CA Performance Center. Each instance can contain multiple users and roles that are not shared among tenants.
tenant administrator
A tenant administrator has permissions to view all data from a single tenant. The tenant administrator can also add configuration, such as group definitions, profiles, and user accounts, to this tenant. This administrator role does not have permission to view items associated with any other tenant.
view
Views, or data views, present statistical data, usually in a graph or table format. Each view represents a discrete set of collected data. Depending on your user account role rights, you can add and edit individual views or remove them from a dashboard page. In some cases, you can export the data to a file in CSV format.
