The Agentless Collector dashboard
On the Application Discovery Service Agentless Collector (Agentless Collector) dashboard page you can see the status of the collector and choose a method of data collection as described in the following topics.
Collector status
Collector status gives you status information about the collector. The collector name, the status of the collector's connection to AWS, the Migration Hub home Region, and the version.
If you have AWS connection issues, you might need to edit Agentless Collector configuration settings.
To edit the collector configuration settings, choose Edit collector settings and follow the instructions described in Editing Agentless Collector settings.
Data collection
Under Data collection you can choose a data collection method. Application Discovery Service Agentless Collector (Agentless Collector) currently supports data collection from VMware VMs and from database and analytics servers. Future modules will support collection from additional virtualization platforms, and operating system level collection.
VMware vCenter data collection
To collect server inventory, profile, and utilization data from your VMware VMs, set up connections to your vCenter servers. To set up the connections, choose Set up in the VMware vCenter section and follow the instructions described in Step 6: Set up Agentless Collector data collection modules.
After you set up vCenter data collection, from the dashboard you can perform the following:
-
View data collection status
-
Start data collection
-
Stop data collection
Note
On the dashboard page, after you set up vCenter data collection, the Set up button in the VMware vCenter section is replaced with data collection status information, a Stop data collection button, and a View and edit button.
Database and analytics data collection
You can run your database and analytics data collection module in the following two modes.
- Metadata and database capacity
-
The data collection module collects such information as schemas, versions, editions, CPU, memory, and disk capacity from your database and analytics servers. You can use this collected information to compute target recommendations in the AWS DMS console. If your source database is overprovisioned or underprovisioned, then the target recommendations also will be overprovisioned or underprovisioned.
This is the default mode.
- Metadata, database capacity, and resource utilization
-
In addition to metadata and database capacity information, the data collection module collects actual utilization metrics of CPU, memory, and disk capacity for the databases and analytics servers. This mode provides more accurate target recommendations than the default mode because the recommendations are based on the actual database workloads. In this mode, the data collection module collects performance metrics every minute.
To start collecting metadata and performance metrics from your database and analytics servers
On the Database and analytics collector page, choose Data collection in the navigation pane.
From the Database inventory list, select the database and analytics servers for which you want to collect metadata and performance metrics.
Choose Run data collection. The Data collection type dialog box opens.
Choose how to collect data for analysis.
If you choose the Metadata, database capacity, and resource utilization option, then set the period of data collection. You can collect data during the Next 7 days or set the Custom range of 1–60 days.
Choose Run data collection. The Data collection page opens.
Choose the Collection health tab to see the status of data collection.
After completing the data collection, your data collection module uploads collected data to your Amazon S3 bucket. Then, you can view this collected data as described in Step 7: View collected data.
