ITOM Guided Set-up

Hey everyone,

Has anyone gone through the ITOM Guided Set-up? How was your experience? Is it easier to setup Discovery?

Hey Rodelio,

Pleasure to "meet" you. Hope this helps you out with your ITOM journey. The   guided set-up ensures you have set up the bare minimums required for Discovery. It doesn't provide any shortcuts though.

The scope of this setup is installing and configuring a MID server, then adding credentials and ranges to Discovery. It doesn't take a great deal of time to complete, but it also doesn't act as a substitute for not knowing how to run Discovery either. If I may, what's your experience with Discovery?

Lisa,
I took the Discovery training course just last month and right now we are setting up the infrastructure to start discovering devices. Our security team wants to enable External Security storage to grant access to devices verse adding a credential to all VMs. I have two mid-server spinning up and we are procuring licenses to support the external storage add-on.

Nice, Rodelio. Should you need assistance with Discovery implementation or better yet, are ready to leverage your Discovery with the power of Service Mapping let me know. In the meantime, enjoy this Technical Dive video into our Service Mapping Factory covering the business value of ITOM QuickStart. The video will show you what more can be achieved above and beyond the OOB module(s) in just a few weeks.

Rodelio,

Hope this finds you well, there is quite a lot of prep steps you need to handle in advance to achieve a maximum result for Discovery and Service mapping.

- Ensure all needed credentials are ready and tested. (Credentials is a make or break mandatory item.), if you have deployed external credential store option, it is very powerful and removes the need for you to constantly change or update credentials in Service-now directly, the credential ID is updted and controlled by the credential store owner, a great option for a large enterprise.

- Check your Probe/Sensor list and their required discovery per-requisites. a lot of times folks rush into discovery with only credentials but forgetting some prerequisites needed for specific sensors like WebSphere MQ, Oracle DB etc.

- If you have devices in DMZ accessed via firewalls, ensure your source IP is always the MID Server that will initiate the connection into he DMZ and that this MID server has the access granted for the PORTS, PROTOCOLS and ACL's to the destination IP / Network targets. Perform a test discovery to confirm.

- Use Discovery behaviors and MID Server Clusters to manage Discovery of dedicated Device types (Load Balancer's (SNMP v3), Network Security Devices etc)

- Ensure your "Hardware Rule" covers all possible hardware device classifications in scope for your discovery.
