Data Collector Considerations

Consider the following information before you install Data Collector:

Install Data Collector on a separate computer from the server where Data Aggregator is installed.
You can install more than one Data Collector. However, each Data Collector must be installed on a separate computer.
Data Collector can support only one Data Aggregator.
In a multi-tenant deployment, Data Collector is not shared among tenants. However, a tenant can have more than one Data Collector.
In a multi-tenant environment where a managed service provider is monitoring devices for multiple tenants, you can take the following steps:
- Install Data Collector at the MSP site.
  Note: This setup requires Data Collector to gain access through a tenant firewall to poll the devices that are being managed.
- Install Data Collector at each tenant site.
If Data Aggregator is IPv6 only, Data Collector must support the IPv6 protocol.
To verify that Data Collector supports IPv6, take the following steps:
- On the Data Aggregator host, type the following command to find the IPv6 address of the computer:
```
> ifconfig
```
- On the Data Collector host, type the following command to ensure that Data Collector can contact Data Aggregator using its IPv6 address:
```
> ping6 ipv6_address_of_Data Aggregator
```
