Ping Monitoring
Ping monitoring checks whether a host is reachable over ICMP and how quickly it responds. Use it to detect host-level availability issues before application-layer checks are affected.
How Ping Monitoring Works
Each check sends an ICMP echo request to your target host and records whether it receives a reply within the configured timeout.
Ping monitoring is useful for quickly identifying:
- Host unreachable events
- Network path issues
- Sudden increases in response time
Limits
Ping monitoring follows the same limits as other monitor types.
Configuration Options
1) Target Host / IP
Set the destination your monitor should ping.
- Domain name (for example:
example.com) - IPv4 address (for example:
1.1.1.1) - IPv6 address (if supported by your environment)
Use a stable hostname or IP that represents the service endpoint you care about.
2) Check Interval
Choose how often UptimeObserver sends a ping check.
- Shorter intervals detect outages faster
- Longer intervals reduce monitoring traffic
Use the same interval strategy you apply to other monitor types.
3) Timeout
Define how long to wait for a ping reply before marking the check as failed.
- Lower timeout: faster failure detection, more sensitive to transient latency
- Higher timeout: fewer false positives during brief network jitter
Common Use Cases
- Verify that critical hosts are reachable from monitoring regions
- Detect infrastructure or routing issues before HTTP failures occur
- Track baseline host responsiveness over time
Troubleshooting
Frequent Timeouts
- Confirm the target host is online
- Check firewall rules and ICMP policies on the host/network
- Increase timeout slightly if your network has variable latency
Intermittent Failures
- Test from multiple networks to isolate routing issues
- Verify no upstream filtering drops ICMP packets
- Correlate incidents with provider/network maintenance windows
Host Resolves but Does Not Reply
DNS resolution can succeed while ICMP traffic is blocked. If this is expected, use an HTTP or Port monitor for service-level validation.
