Terminology
The following terms explain the key concepts used with discovery:
- Discovery is the tool that automatically discovers devices in your network. You supply the discovery tool with a range or list of IP addresses, and the discovery tool determines if a device exists at each IP address. For each device the discovery tool "discovers", the discovery tool can collect a list of open ports, DNS information, SSL certificates, a list of network interfaces, device classes to align with the device, and basic SNMP information about the device. The discovery tool also determines which (if any) Dynamic Applications to align with the device. If the discovery tool finds Dynamic Applications to align with the device, the discovery tool triggers collection from the device, using each aligned Dynamic Application.
SL1 also uses discovery to update information about an already-discovered device and to add new information about an already-discovered device.
NOTE: Discovery collects a very specific set of information for each discovered device. Data that is not retrieved by discovery is retrieved by collection.
- Collection is the tool that retrieves policy-based information and Dynamic Application-based information from a device. After a device is discovered, you can define monitoring policies for that device in SL1. For example, if you define a policy to monitor a system process, the collection tool retrieves that information.
- Credentials are access profiles (usually username, password, and any additional information required for access) that allow SL1 to retrieve information from devices and from software applications on devices. Discovery uses SNMP credentials to retrieve SNMP information from each discovered device. Dynamic Applications use credentials to retrieve SNMP information, database information, SOAP information, XML information, and LDAP and AD information.SL1 also includes a type of credential called "Basic/Snippet" that is not bound to a specific authentication protocol. You can use this type of credential for Dynamic Applications of type "WMI", of type "snippet", and when defining system backups. Another type of credential allows Dynamic Applications of type "Snippet" to use SSH to communicate with a remote device.
