The application installs related ServiceNow Store applications and plugins if they are not already installed.") from ServiceNow Store. Role required: service_mapping_admin ## About this task Service Mapping performs an automatic scan of the following resources and configurations to give you the readiness status: * (Mandatory) There are MID Servers with correctly configured IP ranges and the applications and capabilities settings. For more information, see [MID Server configuration for Service Mapping](https://servicenow-prod.fluidtopics.net/zWlPCWfb7dE865TT7wtHHA "Configure Service Mapping and MID Servers to work together."). If this check does not recognize correctly configured MID Servers, you cannot perform the bulk discovery. * (Optional) There are credentials for operating systems and applications as described in [Prerequisites for performing top-down discovery using Service Mapping](https://servicenow-prod.fluidtopics.net/20BFFRIMDaojk1En5RNucg "Learn about credentials, users, and user permissions you must configure to let Service Mapping access and discover applications inside your organization private network."). * (Optional) There are at least three load balancers recently discovered during horizontal discovery. * (Optional) There are at least 100 hosts discovered by the horizontal discovery in the last 14 days. * (Optional) The data collection using Netflow or VPC Flow Logs is configured. This configuration is necessary to enhance the traffic-based discovery in Service Mapping. For more information, see [Data collection and discovery using Netflow](https://servicenow-prod.fluidtopics.net/YBbys5myQUEDZ6mfzThrYQ "Service Mapping can perform discovery based on data collected using the Netflow protocol. Netflow is a protocol that Service Mapping can use to collect data about CIs and their connections along with Netstat and lsof commands.") and [Data collection and discovery using VPC Flow Logs](https://servicenow-prod.fluidtopics.net/DK_4puB5aelFPZFGyXMZEw "Service Mapping can perform discovery based on data collected using VPC Flow Logs. Amazon VPC hosts Amazon Elastic Compute Cloud (EC2) instances that provide Amazon Web Services. VPC Flow Logs collect data on IP traffic going to and from network interfaces in the VPC."). * (Optional) Cloud Discovery is activated and configured. This setting is necessary to discover application service based on IaaS. {#check-service-mapping-readiness-for-mapping__ul_sln_sdr_l1b} If an optional resource or configuration is missing, you can still map application service, but it may result in partial discovery of some CIs and connections. In addition, Service Mapping performs the readiness check for mapping functionality based on Predictive Intelligence. ## Procedure 1. Navigate to AllService MappingHome. The Home page displays only information on service instances that Service Mapping can discover or already discovered. The Home page does not display information on service instances that are created manually or using the API. 2. Verify that Service Mapping is set up and ready for discovery. If some obligatory configurations are missing, the error displays at the top of the window. 1. Click the link in the error or click the Readiness Checklist icon (![Readiness Checklist icon]()). 2. In the Service Mapping Readiness Checklist window, click the link next to the setup category with the error icon (![Error icon]()). You cannot perform discovery and mapping unless there are no errors in the Readiness Checklist window. 3. Perform the necessary action to complete the setup. For example, configure missing credentials. {#check-service-mapping-readiness-for-mapping__CompleteSetupAction} {#check-service-mapping-readiness-for-mapping__CompleteSetupAction} {#check-service-mapping-readiness-for-mapping__substeps_t13_qvy_31b} 3. If more than one setup category has an error, return to the Readiness Checklist window and fix any other errors. 4. Verify that Service Mapping is ready for discovery based on Predictive Intelligence. 1. Navigate to WorkspacesService Mapping, and then select Application Service Readiness icon ![](). 2. Verify that all items in the Prerequisites status list are in the Ready state. If any prerequisites are not fulfilled, perform the necessary procedure, and then select Check readiness. {#check-service-mapping-readiness-for-mapping__substeps_q2r_d3y_2sb} ## What to do next [Map business services in bulk](https://servicenow-prod.fluidtopics.net/X_hy5lHOO9fQgYN74U~9AA "You can perform initial mapping of multiple or single application services in your organization using a method that best suits you.") **Related reference** * [Application service readiness dashboard in configurable workspace](https://servicenow-prod.fluidtopics.net/Kjpj665ke2wNGHDg8A4kcw "Review the information on the dashboard to confirm that you’re ready to discover and map application services based on machine learning (ML). Service Mapping uses data processed by Predictive Intelligence to generate suggestions for traffic-based connections.") *[\>]: and then
