Ping a host over the SIM connection
Ping a host over the SIM's data connection and measure round-trip time, jitter and packet loss.
The reference action for tracking cellular network latency over time. A ping sends small network packets (ICMP) to a host and times the reply: round-trip time is the delay, jitter is how much that delay varies, and packet loss is the share of packets that never come back. When a firewall filters ICMP, use TCP Ping instead.
Parameters
| Parameter | Required | Description |
|---|---|---|
| Host | Yes | Host to ping, for example 8.8.8.8 or google.fr. |
| Ping count | No | Number of pings. Default: 10. |
| Packet size | No | Packet size in bytes. Default: 64. |
| Ping should fail | No | Invert the verdict. |
Plus the shared connection settings: access technology, APN, keep PDP context, check network. The action ships with a default assertion: packet_loss == 0.
Results and metrics
In the action report (result):
| Field | Description |
|---|---|
rtt_mean | Mean round-trip time. |
jitter | Variation between round-trip times. |
packet_loss_pct | Percentage of lost packets. |
ping_count, packet_size, ping_duplicate | The run's parameters and duplicate count. |
duration | Total execution time in seconds. |
In Analytics, each run feeds the ping measurement with rtt_seconds, jitter, packet_loss_percent, and duration_seconds, tagged by status, APN, DNS server, antenna, and access technology. These are the series behind latency dashboards and alert thresholds.
