After the installation there is already a first collector: the ARM server itself.
Additional collectors may be installed for the following reasons:
- You want to connect remote resources. Installing collectors on remote systems reduces the WAN footprint and improves performance when executing scans or making access rights changes.
- Some resource types and features require the installation of additional collectors, for example FS Logga for Windows Fileserver.
- Load balancing.
- To incorporate foreign domains (non-trusted) a collector must be installed. Please see Collectors in foreign domains (non-trusted) for more details.
