Then, it uses the credentials already added in the application to\naccess the discovered servers, and adds them to the inventory. This\napproach is useful when you have a large number of servers to add, or you're not\nsure about the exact IP addresses of your infrastructure.\n\nAlternatively, you can manually add your servers one by one from the\napplication, or by providing a CSV file with a list of IP addresses. This\napproach is useful when you have a limited number of servers to scan and you\nknow exactly their IP addresses.\n\nBefore you begin\n----------------\n\n- Add the credentials that the discovery client uses to access your servers.\n\nLimitations\n-----------\n\n- The discovery client application supports the discovery of up to 10,000 servers.\n- You can create up to 100 IP ranges. Each IP range can contain at most 65,536 IPs.\n- The discovery client supports IP addresses using the IPv4 protocol.\n\nAutomatically add servers to scan\n---------------------------------\n\nThe discovery client can automatically identify servers to add to your\ninventory with the IP range scan feature. When performing an IP range scan, the\ndiscovery client sends Internet Control Message Protocol (ICMP) requests\nwith the `ping` command. To be able to use IP range scan, make sure that your\nfirewall rules allow ICMP requests from the discovery client.\n\nYou can manually add each IP range from the application UI, or upload a CSV\nfile with a list of ranges.\n\n### Add IP ranges from the application UI\n\nTo add a new range of IP addresses to scan from the application UI, do the\nfollowing:\n\n1. In the discovery client application, go to the **Discovery** tab.\n2. In the **IP addresses/ranges** page, click **Add IP addresses \\\u003e Add ranges\n manually**, then agree to the terms and conditions for the scan.\n3. Enter the initial and final IP addresses of the range. To add another\n range to the same scan, click **Add IP range**, then enter the new pair of\n IP addresses.\n\n **Tip:** Include all the IP ranges that share the same credentials for\n authentication in the same list.\n4. To finish, click **Save**.\n\n### Import IP ranges from CSV\n\nTo add multiple IP ranges at the same time, follow these steps:\n\n1. In the discovery client application, go to the **Discovery** tab.\n2. In the **IP addresses/ranges** page, click **Add IP addresses \\\u003e Add ranges\n via CSV**, then agree to the terms and conditions for the scan.\n3. In the new dialog that appears, download the template and fill in the IP\n address ranges that you want to scan. The template has the following format:\n\n \"StartIpAddress\",\"EndIpAddress\"\n 10.10.10.1,10.10.10.255\n 10.10.11.1,10.10.11.255\n\n4. Browse to upload the template that you modified with your ranges, then\n click **Upload**.\n\nAfter you upload the file, the discovery client scans all the IP addresses\nin the ranges and pings each server.\n\nTo verify which servers are discovered, follow these steps:\n\n1. In the **Discovery** tab, click **IP addresses**.\n2. From the list of IP ranges, click the range that you want to view.\n3. In the **Scan details** section, review the list of IP addresses of the discovered servers and their status.\n\n### Import IP addresses from CSV\n\nTo add multiple IP addresses at the same time, follow these steps:\n\n1. In the discovery client application, go to the **Discovery** tab.\n2. In the **IP addresses/ranges** page, click **Add IP addresses \\\u003e Add address\n list via CSV**, then agree to the terms and conditions for the scan.\n3. In the new dialog that appears, download the template and fill in the IP\n addresses that you want to scan. The template has the following format:\n\n ipAddress\n 10.10.10.10\n 10.10.10.11\n\n4. Browse to upload the file that you modified with your addresses, then\n click **Upload**.\n\n### Scan statuses\n\nWhen you perform a server scan, the servers that you discover appear in\none of the following statuses:\n\n- **Success:** The discovery client pinged and authenticated to the server correctly.\n- **Already listed:** The server was already added to your inventory during a previous scan.\n- **Authentication failed:** The discovery client was able to ping the server, but couldn't authenticate using the credentials provided.\n- **Pending validation:** In case of an IP addresses list, this is the server status before the discovery client completed the attempts to find a credentials match.\n\nManually add servers to scan\n----------------------------\n\nIf you have individual servers in your infrastructure that you want to scan,\nyou can manually specify the connection details and credentials. Follow these\nsteps:\n\n1. In the discovery client application, go to the **Servers** tab.\n2. Click **Add information manually**.\n3. In the **Add information manually** page that opens, enter the following information:\n 1. The credentials needed to connect to the server\n 2. The name of the server\n 3. The IP address of the server\n 4. The OS type of the server\n4. To verify that the information you entered is correct, click **Test\n connection**.\n5. Optional: to customize the scanning schedule, do the following:\n 1. Click the **Schedules for opting out of scanning** to the on position.\n 2. Click **Create new opt-out schedule**.\n 3. Enter a name for your opt-out schedule. You can later use the same schedule for other assets.\n 4. Select the days when the collection shouldn't run.\n 5. For each day, select the two-hour time slots when the collection shouldn't run.\n 6. To create your opt-out schedule, click **Save and continue**.\n6. To confirm the server details, click **Save**.\n\nAdd vCenter for discovery\n-------------------------\n\nTo discover your vCenter VMs, follow these steps:\n\n1. In the discovery client application, go to the **Discovery** tab.\n2. Click **vCenter**.\n3. In the **vCenter** page, click **Add vCenter.**\n4. In the **Add vCenter** page that opens, enter the following information:\n 1. The credentials needed to connect to the vCenter.\n 2. The URL of the vCenter. For example: `https://172.0.0.1` or `http://172.0.0.1`.\n 3. Optional: to reduce the scope of the collection, add the inventory path. For example: `MyDataCenter/vm`.\n 4. Optional: to run a guest discovery of your servers, provide the guest credentials for Linux and Windows machines.\n 5. Select if you want to allow HTTPS access using self-signed, less secure certificates.\n 6. Select if you want to turn on performance data collection on vCenter.\n5. To verify that the information you entered is correct, click **Test\n connection**.\n6. To confirm the server details, click **Save**.\n\nConfigure the scan schedule\n---------------------------\n\nThe discovery client lets you configure when to scan your infrastructure.\nBy default, the discovery client performs a full collection\nevery 24 hours, and collects performance data every 10 minutes, but you\ncan choose to pause the collection during specific days and hours of the week.\nThis is useful, for example, to avoid additional load on your machines during\npeak times, or to stop the collection when you're not using your machines,\nto avoid skewing the performance data.\n\nTo configure a scan schedule for servers that are already present in the\ndiscovery client, follow these steps:\n\n1. In the discovery client application, go to the **Servers** tab.\n2. From the list of available servers, select those for which you want to customize the schedule, then click **Configure schedule**.\n3. If you have already created a scan schedule, click **Select existing\n opt-out schedule** , then select the schedule from the list. Otherwise, click **Create new opt-out schedule** and do the following:\n 1. Enter a name for your opt-out schedule. You can later use the same schedule for other assets.\n 2. Select the days when the collection shouldn't run.\n 3. For each day, select the two-hour time slots when the collection shouldn't run.\n4. To confirm your opt-out schedule, click **Save**.\n\nWhat's next\n-----------\n\n- Learn how to [manage discovery client](/migration-center/docs/manage-discovery-client)."]]
