The poller should be installed on a dedicated fresh CentOS 7 server.
Hardware
The host machine must have at least the following characteristics:
| Element | Value |
|---|
| CPU (logical core at 3Ghz) | 1 CPU |
| RAM | 4 GB |
| HDD | 40 GB |
It is recommended to partition the poller's disk to prevent it from becoming full and unusable (for instance, in case of retention issues).
Perform the partitioning following these recommendations:
| File system | Size |
|---|
| swap | 1 to 1.5 total size of RAM space |
| / | at least 20 GB |
| /var/log | at least 10 GB |
| /var/lib/centreon-broker | at least 5 GB |
| /var/cache/centreon/backup | at least 5 Go (export the backups and delete the exported data daily) |
Network
| Description | Direction | Protocol | IP | Port |

| VPN | Outbound | UDP | VPN IP (TBA) | 1194 |
| INTERNET | Outbound | HTTP/HTTPS | * | 80/443 |
