com.snc.pattern.designer Why is this missing from the PDI?

[Royal Sirrine1]

Looking around and learning more about the CMDB, I was browsing the plugins and saw that Discovery and Service Mapping Patterns is available in the ITOM list, but when trying to instal the plugin, there is an error that states that com.snc.pattern.designer needs to be installed. However, that ID is not something I can find in my PDI. Is this restricted in PDI's? and if so, why?

Hi -- Have you installed the Discovery plugin?  or perhaps Service Mapping plugin too?   I believe (going from memory here...) that the Pattern Designer is added when the Discovery plugin (or SM?) is enabled.  If Disco and/or SM are active, then the pattern designer should certainly be exposed & active.

After Disco/SM is installed (and therefore the PD too), then plugin you mentioned "Discovery and Service Mapping Patterns" could be installed next.  But I since you are just trying to learn about CMDB and 'browsing plugins'  I'd start with the basics of Discovery & MID server usage.  The plugin you tried to installed allows you to get additional patterns from store.servicenow...  but thats putting the cart before the horse.   I suggest focusing on basics of learning Discovery (when enabled) and then worrying about the store plugin later as your understanding evolves.

Hope this helps?

That's what I was trying to do in the PDI. But when trying to install the plugin, there is an error stating it requires com.snc.pattern.designer. Unless there is another plugin that does not appear in the PDI for Discovery and Servicemapping? I was afraid it would be like how you cant install items like PagerDuty or xMatters on PDI's for proof of concepts or personal development. 

But perhaps I am confusing as you mentioned in your last section what I was trying to install is not the discovery portion, rather the patterns.

EDIT:

I am trying this:

Please go to developer.servicenow.com and login with your credentials, there you can see Manage Instance option when you click there you can see an Action button

there you have an option for Activate plugins(choose the plugin from that list)

On your PDI you can certainly install the plugins yourself.  I've got Disco, SM and Cloud Mgmt plugins enabled on my PDI.  On the developer site Manage>Instance... and then under Action its possible to active more plugins from a list.   If you don't have Discovery installed, then definitely do this 1st... I pretty sure it'll include the Pattern Designer components too.

Hope this helps?
