# (Optional) Configuring a Collector

If only one collector is available, the new AntiDDoS devices or AntiDDoS1820-N devices are automatically associated with the collector. If multiple collectors are available, associate AntiDDoS devices or AntiDDoS1820-N devices with the given collector.

The management center is composed of ATIC server and collectors. The collectors collect, parse, summarize, and store traffic and logs from AntiDDoS or AntiDDoS1820-N devices. Therefore, collectors need to be added to the ATIC during the configuration of anti-DDoS services. You can view the performance data of the added anti-DDoS collectors, modify the collectors, or delete them.

Choose Defense > Network Settings > Collectors, and manage collectors.

Create | Click to add a collector in the ATIC Management center. For details, see Adding a Collector.
Associate Device | Click of a collector and bind the collector to one or more AntiDDoS devices. For details, see Associating the Collector with Devices.
Modify | Click of the collector to be modified to change the collector parameters. NOTE: The collector in Down state cannot be modified.
Delete | Delete one collector: Click in the Operation column to delete the corresponding collector. Delete collectors in batches: Select the check boxes of multiple collector names and click above the list to delete the selected collectors. Select the check box on the title bar and click above the list to delete all collectors. NOTE: Collectors being associated with the device cannot be deleted.
State | Indicates the connection state between the ATIC server and the collector. indicates that the collector is online. That is, the ATIC server and collector are connected and the collector service has been started. indicates that the collector is offline. The possible causes are: the IP address of the collector is changed, the ATIC server fails to connect to the collector, and the collector service is not started.
Device Quantity | Indicates the number of devices bound to the collector.
CPU, Memory, Disk Information | Indicates performance data including information about CPUs, memory, and disks of collector servers.

- Adding a Collector
  After the centralized installation is complete, the ATIC Management center automatically creates a collector. You must manually create collectors during the distributed installation.
- Associating the Collector with Devices
  Devices can send logs and captured packets to the anti-DDoS collector after being associated for future analysis. When only one anti-DDoS collector is available, the collector is automatically associated with devices. When multiple anti-DDoS collectors exist, associate them with devices manually. You are advised to associate each collector with one device.
