Hello Sarada and thank you for your post!
It sounds like you have installed with VMware. Let me know if this assumption is not correct.
Let's start with your questions:
1. You can verify the settings that have been used when installing the analytics subsystem with the following command:
./apicup subsys get <analytics-subsystem-name>
If ingestion-only is set to true then you are using internal storage.
2. It is not required that you set internal storage space before deployment. When using VMware I believe that the storage space is dictated by the disk available to the VM, which you can alter via VMware. I would recommend that you review this Knowledge Center topic if you have not already:
https://www.ibm.com/support/knowledgecenter/en/SSMNED_v10/com.ibm.apic.install.doc/analytics_plan_est_space_vm.html#analytics_plan_est_space_vm__master_storage3. You do not need to create an analytics-extra-values.yaml file. This file is required if you need to override deployment settings that are not exposed via the installer (apicup).
Now to the problem you are experiencing:
There is a known issue when enabling the message queue in v10 that can cause analytics to fail to ingest data from the gateway. Have you set enable-message-queue to true when deploying analytics? This also has implications for storage space so I'll wait for you to confirm this one way or the other before we explore other potential causes.
Kind regards,
Mark
