When setting up a GlobalProtect Portal/Gateway with AzureAD you may find you receive the error message:
AADSTS700016: Application with identifier <Entity ID> was not found in the directory ‘<Directory ID>’.
The fix here is easy – the GlobalProtect client injects a :443 at the end of the domain name which isn’t mentioned in the guide from Microsoft (https://docs.microsoft.com/en-us/azure/active-directory/saas-apps/palo-alto-networks-globalprotect-tutorial) but is in the guide from Palo Alto Networks (https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g0000008U48CAE).
Interestingly the Reply URL doesn’t specifically require it (although mentioned in the Palo Alto guide) but either way easy to fix.
If you are looking to build out Zone Protection Profiles on your Palo Alto Networks Next Generation Firewall then it can be handy to know just what your connections per second metrics look over time for each zone. Quite lucky Palo Alto Networks have a little (although not entirely descript) guide on where you can get this data – https://docs.paloaltonetworks.com/pan-os/9-1/pan-os-admin/zone-protection-and-dos-protection/zone-defense/take-baseline-cps-measurements-for-setting-flood-thresholds/how-to-measure-cps.html.
With that information in hand it was just a matter of time before working out how to collect this data through PRTG so do follow on with the screenshot guide to find out how!
