In ENA, users will need to configure their Amazon Web Service (AWS) and Microsoft Azure instances to ensure that ENA is able to monitor and collect information on them. It is essential that these are configured, because otherwise ENA will not be able to collect all information for them.
Note, on Azure, if the allocated diagnostics space is exhausted, there is the potential for ENA to stop gathering data. You should ensure that you have sufficient diagnostics space available to continue monitoring virtualization platforms. It is recommended that you periodically remove old WAD tables from the storage accounts to prevent running out of space and to avoid incurring unnecessary costs.
Important note: for both AWS and Azure, producing and storing diagnostic data incurs additional costs as does the retrieval of this data via ENA.
