Conditional Alert Rules
Set up sophisticated alert conditions based on response time, status changes, content validation, and more
Response Time Threshold
Alert if response time > 500ms
response_time > 500Port Status Change
Alert when port closes or opens
status != previous_statusBanner Content Validation
Alert if banner doesn't match expected
banner NOT CONTAINS "expected_text"Consecutive Failures
Alert after 3 consecutive failures
consecutive_failures >= 3Response Code Check
Alert if response code is unexpected
response_code NOT IN [200, 220, 250]Uptime Percentage
Alert if uptime < 99%
uptime_percentage < 99Advanced Alert Configuration
Alert Timing
- Immediate: Alert on first failure
- After X failures: Wait for consecutive failures
- Time window: Alert if down for X minutes
- Recovery delay: Wait before sending recovery alert
Threshold Settings
- Response time: Alert if > threshold (ms)
- Packet loss: Alert if > X% packets lost
- Uptime: Alert if uptime drops below %
- Custom metrics: Define your own thresholds
Content Validation
- Contains text: Banner must include string
- Regex match: Response matches pattern
- Response codes: Expected status codes
- DNS records: Validate IP addresses
Alert Channels
- Email: Multiple recipients with templates
- SMS: Instant text message alerts
- Slack/Teams: Team collaboration channels
- Webhooks: Custom integrations
Create complex alert rules with AND/OR logic for maximum flexibility
(response_time > 500 AND consecutive_failures >= 2) OR (status == "closed")Advanced Features

Trusted by Network Teams
"The conditional alerts are game-changing. We set up alerts for response time > 200ms and caught network degradation before customers noticed."
"Monitoring all our service ports (SMTP, FTP, MySQL) from one dashboard saves us hours daily. The banner validation feature is brilliant."
"We monitor 500+ ports across 50 servers. The global monitoring from multiple locations gives us confidence in our infrastructure health."
