What are the phases on the Discovery?

Hello All, 

Can you help me to know what are the phases on the Discovery, please?

Thanks a lot

Hi @1__MiguelAngeR ,

Horizontal discovery phases

The phases of horizontal discovery are:

Discovery follows these phases: Scanning Discovery sends a probe called Shazzam to the network to see if commonly used ports are open and if these ports can respond to queries. For example, if Shazzam finds a device that responds on port 135, Discovery knows that it’s a Windows server. Classification If Discovery finds devices or computers, it sends additional probes to find the type of device or the operating system on the device. For example, Discovery sends the WMI probe to a Windows machine to detect the Windows 2012 operating system. Then Discovery uses records called classifiers, which specify the trigger probe or probes that run during the next two phases. If you’re using patterns, the classifier specifies a trigger probe that in turn launches a pattern. Identification Discovery tries to gather more information about the device and then tries to determine if a CI for the device exists in the CMDB. Discovery then uses additional probes, sensors, and identifiers to update existing CIs in the CMDB or create new ones. Identifiers, also known as identification rules, specify the attributes that the probes look at when reconciling data with the CIs in the CMDB. If you’re using patterns, Discovery uses the appropriate identification rule for the CI type specified in the pattern. Exploration The identifier launches additional probes configured in the classifier. These probes are especially designed as exploration probes to gather additional information about the device, like the applications running it, and additional attributes, such as memory, network cards, and drivers. Discovery then creates relationships between applications and devices and between applications. If you’re using patterns, the operations in the pattern perform the exploration of the CI.

Hi,

Below are the phases - 

1) Scanning: Focus on categorizing the discovered device. Using a shazzam probe, port scans check for open ports in the network.
2) Classification: This phase attempts to classify the device precisely.
3) Identification: In this phase, CMDB records are examined to check if there are any identical devices found.
4) Exploration: Patterns are used to gather more detailed information to populate CI attributes.

Thanks.
