# Private Location Orchestrator A server that allows private regions to register and ingest data from them. ## ICMP monitors ICMP (ping) monitors run from the checker agent. Sending ICMP echo requests needs one of the following on the host running the agent: - **Unprivileged datagram sockets** — set `net.ipv4.ping_group_range` to a range that includes the agent's GID (e.g. `sysctl -w net.ipv4.ping_group_range="0 2147483647"`). The agent prefers this path and needs no elevated capabilities. - **Raw sockets** — grant the binary `CAP_NET_RAW` (`setcap cap_net_raw+ep `) or run it as root. The agent falls back to this automatically when datagram sockets are unavailable. Without either, ICMP checks fail to open a socket and are reported as errors.
