Register Data Sources
During the installation, you registered the Data Aggregator as a data source. Many implementations of 
CA Performance Management
 include other data sources, such as CA Spectrum and CA Network Flow Analysis. To import inventory from other data sources, register those data sources. If this installation includes only the Data Aggregator, skip this procedure.
For more information about data sources and synchronization, see Manage Data Sources.
 
Follow these steps:
 
  1. Log in to 
    Performance Center
     as an administrator user. Access 
    Performance Center
     at the following URL:
    PC_host:8181/pc/desktop/page
  2. Hover over 
    Administration
    , and click 
    Data Sources: Data Sources
    .
  3. Click 
    Add
    .
  4. Select the Source Type, specify the required information, and click 
    Save
    .
    CA Performance Management
     synchronizes with the data sources and adds the relevant devices.
Quickly Discover Devices
Discovery is the process that 
CA Performance Management
 uses to build an inventory of devices in your network. You can quickly discover devices without having to configure SNMP profiles and discovery profiles manually.
For more information, see Discovery.
 
Follow these steps:
 
  1. Hover over 
    Administration
    , and click 
    Monitored Items Management: Quick Device Discovery
    .
  2. Complete the following fields:
    •  
      IP Domain
      If you have multiple IP domains, select the IP domain for discovery.
       
    •  
      Community Name
      (SNMPv1/v2c Only) Specify a secure string that lets the data source query the MIB of the associated device. The community that you supply must provide read access to the device MIB.
    •  
      Verify Community Name
      Specify the Community Name again for verification.
    •  
      Port
      Specify the port that is used to make SNMP connections to your devices.
      Default
      : 161
      This port can also be used to send SNMP traps to trap receivers associated with this profile through notifications. In this scenario, use 162 by default. For more information, see Configure Notifications.
    •  
      IPs/Host
      Specify the IP address ranges that you want to discover for IPv4. Range discovery is not supported for IPv6 addresses.
  3. Click 
    Discover
    .
    CA Performance Management
     discovers the devices within the specified IP addresses and hostnames, and adds the devices to the system inventory.
Discover Devices
If you do not use quick discovery, you can configure SNMP profiles and discovery profiles manually.
The following video examines the detailed steps that are required to discover devices:
 

 
For more information, see Discovery.
Configure SNMP Profiles
SNMP profiles provide authentication credentials to communicate with devices in your network.
 
Follow these steps:
 
  1. Hover over 
    Administration
    , and click 
    Configuration
     
    Settings: SNMP Profiles
    .
  2. Click 
    New
    .
  3. Complete the fields, and change any default settings. Some fields apply only to SNMPv3.
    For complete details, see SNMP Profiles.
  4. Click 
    Save
    .
    The SNMP profile is added to the system and used for discovery and polling.
Create Discovery Profiles
Discovery profiles specify which devices 
CA Performance Management
 discovers. Create granular discovery profiles for devices with different SNMP credentials or different rediscovery schedule. Granular discovery profiles reduce unnecessary SNMP requests.
For more information, see Discovery Profiles.
 
Follow these steps:
 
  1. Hover over 
    Administration
    , and click 
    Monitored Items Management: Discovery Profiles List
    .
  2. Click 
    New
    .
  3. Specify a name for the profile.
  4. Specify the IP address, IP ranges, or hostnames to target for discovery.
  5. (Optional) Open the 
    SNMP
     tab, select 
    Use specific list of assigned SNMP profiles
    , and select the SNMP profiles to include in discovery.
    Using a specific list of SNMP profiles reduces unnecessary SNMP requests.
  6. (Optional) Open the Schedule tab, and define a schedule.
    During normal operation, discovery runs on a schedule basis to discover new devices in the target range.
  7. Click 
    Save
    .
    CA Performance Management
     uses the discovery profile to find devices in your network.
Run Discovery
To build your inventory, use the discovery profiles to run discovery.
 
Follow these steps:
 
  1. Select the discovery profile.
  2. Click 
    Run
    . You can run discovery only if the State is Ready.
    CA Performance Management
     discovers the devices within the specified IP addresses and hostnames, and adds the devices to the system inventory.
    To view a list of the discovered devices, select the discovery profile, and click History.
Configure Monitoring Profiles
Monitoring profiles control how often to poll devices and which information to collect. Metric families are related sets of metrics that are collected across several technologies. The metric definitions determine how to report the values for the metrics. Metric families normalize performance data from different devices and device types. Assigned metric families determine which metrics the system collects. Collections are system groups that group devices for monitoring. Associating a collection with a monitoring profile causes 
CA Performance Management
 to monitor the devices according to the parameters in that profile.
For more information, see Configure Monitoring Profiles.
Configure a Collection
Consider the following best practices for organizing devices into collections for monitoring:
  • Create custom collections that match the monitoring requirements in the environment.
    • Consider the different layers of the network, access, distribution, and core. Devices in different layers might require different levels of monitoring. 
    • Consider which technologies and metric families are required. Metric families that would be applied to all devices, such as CPU and memory, apply to broad collections. Targeted monitoring, such as QoS and IPSLA, apply to limited collections.
  • Create collections that enable the flexibility to break out monitoring.
    • Some devices are included in multiple collections so that specific metric families are polled at different rates.
    • Devices in different collections have different filtering criteria.
    • Different monitoring requirements depending on importance of device
 
Follow these steps:
 
  1. Hover over 
    Administration
    , and click 
    Group Settings: Groups
    .
  2. Select the 
    Collections
     folder in the left pane.
  3. Click 
    Add Group
    .
  4. Specify a name, and click 
    Save
    .
    The collection is created. To add devices to the collection, add rules.
  5. Click the 
    Rules
     tab, and click 
    + Add Rule
    .
  6. Specify a rule name, select devices for the item type, add conditions as required, and click 
    OK
    .
  7. Click 
    Save and Run Rules
    .
    CA Performance Management
     adds the items to the collection.
Create a Monitoring Profile
Consider the following best practices for creating monitoring profiles:
  • Copy default monitoring profiles to create customer-specific monitoring profiles. Remove the collections that are applied to the default monitoring profiles. This model makes it easier to customize and manage device polling.
    Do not modify the DA Health Fast, Normal, and Slow monitoring profiles. These profiles are used for self-monitoring of the 
    CA Performance Management
     components.
  • For monitoring flexibility, use multiple monitoring profiles. Do not add all metric families that you monitor in your network to a single monitoring profile.
  • Some metric families, such as CPU and Memory, apply broadly to all devices. You can apply a monitoring profile with these metric families to all-encompassing collections, such as All Routers or All Managed Devices.
  • Monitoring profiles control the poll rate. To poll the same metric family on different devices at different rates, create monitoring profiles with different poll rates. Apply the faster poll rate to a collection that includes only the devices that require fast polling.
  • Monitoring profiles control filtering. If different filtering criteria is required for different sets of devices, create a monitoring profile for each set of requirements.
  • Apply only metric families that are applicable to the items in the associated collections. For example, do not apply a monitoring profile that contains the VMWare metric families to a collection of routers. Unnecessary metrics add processing to the Data Aggregator at every change detection period.
 
Follow these steps:
 
  1. Hover over 
    Administration
    , and click 
    Monitored Items Management: Monitoring Profiles
    .
  2. Click 
    New
    , or select an existing profile and click 
    Copy
    .
  3. Specify a unique profile name and description.
  4. Select a poll rate.
     Five minutes is the standard poll rate for most devices in most networks. One-minute polling adds strain to the system and increases SNMP traffic.
  5. To assign the metrics that the system collects for your devices, select metric families.
    Example:
     To report and view port information for your devices, select the Interface metric family.
  6. Click 
    Save
    .
Assign the Collection to the Monitoring Profile
 
Follow these steps:
 
  1. Select your monitoring profile from the list.
  2. Click the 
    Collections
     tab.
  3. Click 
    Manage
    .
  4. Select your collection, and click 
    Save
    .
    CA Performance Management
     uses the metric families in the monitoring profile to poll the items in the collection.
After you configure monitoring, configure reporting. For more information, see Configure Reporting in a New Environment.
