Discovery

Discovery is the process that capm uses to identify the devices on your network. Devices are identified using the IP domain, IP addresses, IP ranges, and hostnames that you specify in discovery profiles.
Discovery is the process that
DX NetOps Performance Management
uses to identify the devices on your network. Devices are identified using the IP domain, IP addresses, IP ranges, and hostnames that you specify in discovery profiles.
Attempts to discover devices are made through SNMP and ICMP protocols. If a device does not respond to SNMP but
does
respond to ICMP, a pingable device is created.
Inventory Discovery
Inventory discovery, or device discovery, identifies the following information about devices:
  • Which protocols the device responds to, SNMP or ICMP
  • The classification of the device, such as router or switch
  • The device vendor, such as Cisco or Juniper
  • The device type, such as 7700 or 8200
Discovered devices and monitored components take up to five minutes to begin synchronizing with
NetOps Portal
.
DX NetOps Performance Management
automatically adds them to device collections depending on the rules that control each device collection membership. During the first synchronization between the data aggregator and
NetOps Portal
after
DX NetOps Performance Management
discovers devices, it adds the devices to collections.
You can discover devices using the following methods:
The following workflow offers a best practice to use as a quick reference when performing a discovery of your inventory. Perform this process as either a user with the Administrator role or as the tenant administrator:
  1. To enable the data collector to perform queries of device MIB tables that use SNMP, create SNMP profiles.
    For more information, see SNMP Profiles.
  2. Create discovery profiles.
    For more information, see Discovery Profiles.
  3. Run discovery and view the results.
    For more information, see Run Discovery.
Metric Family Discovery
Metric family discovery, also known as component discovery, is a separate process that determines whether a specific metric family is supported for a device. A metric family defines the set of metrics to collect and report on for a given technology.
DX NetOps Performance Management
normalizes the values of the metrics so that reporting is uniform regardless of the data source.
Polling begins automatically after metric family discovery completes.
DX NetOps Performance Management
collects and retains operational metrics at regular polling intervals for reporting. Examples of operational metrics include error rate, utilization, and bytes in. Configuration data represents or identifies a component or the component configuration, such as port type or component index.
For more information, see Configure Monitoring Profiles.
Quickly Discover SNMP Devices
Discovery is the process that
DX NetOps Performance Management
uses to build an inventory of devices in your network. You can quickly discover devices, such as SNMP devices, without having to configure SNMP profiles and discovery profiles manually.
For more information, see Discovery.
Follow these steps:
  1. Hover over
    Administration
    ,
    Monitored Items Management
    , and then click
    Quick Device Discovery
    .
    The
    Quick Device Discovery
    page appears. By default,
    SNMP devices
    is selected, and the
    SNMPv1/SNMPv2C
    SNMP protocol is selected.
  2. Complete the following fields:
    • IP Addresses or Host Names
      Specify the IP address ranges that you want to discover for IPv4. Range discovery is not supported for IPv6 addresses.
    • 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.
    • Community Name
      (SNMPv1/SNMPv2C 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.
    • Re-enter Community Name
      Specify the Community Name again for verification.
  3. Click
    Discover
    .
    DX NetOps Performance Management
    discovers the devices within the specified IP addresses and hostnames, and adds the devices to the system inventory.
