- Define Thresholds for Traffic Metrics: Set specific thresholds for key metrics such as traffic volume, connection attempts, and packet loss to trigger alerts when they exceed normal levels.
- Choose Notification Methods: Decide how alerts will be communicated–via Syslog messages, SNMP traps, or email notifications.
- Test and Validate: Simulate traffic anomalies to confirm that the alert system triggers and notifications are properly sent.
Example Configuration for Bandwidth Monitoring
To monitor bandwidth usage and receive alerts when traffic exceeds the defined threshold, you can configure the following commands:
set system syslog host 192.168.1.100 any emergency set system syslog host 192.168.1.100 any info set system syslog host 192.168.1.100 any notice
Note: Replace "192.168.1.100" with the actual IP address of your Syslog server.
Key Traffic Metrics to Monitor
Traffic Metric | Description | Alert Trigger |
---|---|---|
Bandwidth Usage | Monitor traffic volume to detect sudden spikes or prolonged high usage that may indicate congestion or attacks. | Threshold Breach |
Packet Loss | Track packet loss which could indicate network instability, poor connectivity, or hardware issues. | Threshold Breach |
