Discovery multiprobes and multisensors

Discovery multiprobes and multisensors

Multiprobes contain one or more simple probes configured to extract specific information from manageable devices by executing multiple queries with a single authentication.

About this task

You can schedule multiprobes to run any time in the discovery process to make exploration more efficient. One common use for multiprobes is as identity probes. Identity probes ask a device for information such as its name and serial number, and then use the results of those queries to update existing CIs in the CMDB.

To process the data returned from a multiprobe, you must create multisensors, which run scripts that process the data returned by the multiprobes. Multisensors typically use the same name as their corresponding multiprobes.

Procedure

  1. Navigate to Discovery > Discovery Definition > Probes.
  2. Click New.
  3. Complete the form using the following settings:
    • Probe type: Multiprobe.
    • ECC queue topic: MultiProbe.
  4. In the Includes probes related list, add the probes you want to include in the multiprobe.
  5. Click Save.

Multiprobes included with Discovery

The following multiprobes are included with the base system.

The corresponding multisensors have the same names.

Note: † This probe requires the installation of a command line tool from Oracle called SNEEP. To download and install this tool, log in to the Oracle website. After this tool is installed, the Solaris - Serial Number probe runs automatically when Discovery detects a Solaris device. For Fujitsu PRIMEPOWER devices, you must run this probe with root credentials.

Add a simple probe to a multiprobe

You can add simple probes to your multiprobe in the Includes Probes related list.

Before you begin

Role required: admin

About this task

You can add simple probes of any type to a multiprobe and mix probe types if necessary.
Warning: Do not add a multiprobe to the Includes Probes related list.

Procedure

  1. Navigate to Discovery Definitions > Probes.
  2. Open a multiprobe from the list.
    You can see the MultiProbe designation in the ECC queue topic column.

  5. Click Save.

Create Discovery multisensors

Create multi sensors to process data returned from multiprobes.

About this task

Figure 3. Discovery Multisensor and Script

Procedure

  1. Navigate to Discovery > Discovery Definition > Sensors.
  2. Click New.
  3. Complete the form using the following settings:
    • Sensor type: MultiSensor.
    • ECC queue topic: MultiSensor.
    • Reacts to probe: Select the probe whose payload this sensor must process.
    • Sensor type: Select one of these options.
      • Javascript: Returned data from the probe is processed in the sensor itself, outside the application, and is visible to the user. This is the most common sensor type.
      • XML: The XML data from the probe is broken into pieces. Some pieces can be used to launch other probes that the original sensor needs to complete all the necessary information about a device.
  4. Right-click the form header, and click Save.
  5. In the Responds to Probes related list, click New.
  6. Complete the form using the following settings:
    • Reacts to probe: Select the probe within the multiprobe that this sensor reacts to. The sensor must be linked to the probe by function, such as network identification or serial number.
    • Script: Enter a script to run before the script in the multisensor. This script defines how the data returned from each probe should be processed.
