Ping Checks
Ping monitors send ICMP echo requests to a host and measure reachability and round-trip time.
Configuration
Section titled “Configuration”| Field | Description | Default |
|---|---|---|
| Host | The hostname or IP address to ping. | Required |
| Count | Number of ICMP packets to send per check. | 3 |
| Timeout | Maximum time to wait for all replies. | 10s |
How It Works
Section titled “How It Works”- YipYap sends the configured number of ICMP echo requests to the target host.
- The check passes if at least one reply is received within the timeout.
- Latency is recorded as the average round-trip time across all successful replies.
- The check fails if no replies are received.
Metrics Collected
Section titled “Metrics Collected”- Round-trip time (min, avg, max): The time it takes for the ICMP packet to travel to the host and back.
- Packet loss: The percentage of packets that did not receive a reply.
Use Cases
Section titled “Use Cases”- Monitoring basic network reachability to a server or appliance.
- Tracking latency trends to detect network degradation before it affects services.
- Verifying that a host is online after a reboot or maintenance window.
Limitations
Section titled “Limitations”Some cloud providers and firewalls block ICMP traffic. If your target host does not respond to pings, consider using a TCP check instead.
Example
Section titled “Example”- Host:
10.0.1.50 - Count: 5
- Timeout: 10 seconds
- Interval: 60 seconds
