Use Cases
- Tracking the uptime of network devices to ensure continuous operation.
- Alerting network administrators when a device has been rebooted, which may indicate potential issues or unauthorized activities.
Monitoring Options
Configuration
- SNMP Version: Select SNMPv1, SNMPv2, or SNMPv3 based on your device's capabilities and security requirements.
- Community: Enter the community string for SNMPv1 and SNMPv2c; typically "public" is used for read-only access.
- Port Number: Default is 161, adjustable if your network configuration differs.
- Timeout: Configure how long the monitor waits for a response, adjustable to accommodate network conditions.
- Retries: Given the unreliability of UDP, configure retries to ensure reliable data retrieval.
Security Settings (SNMPv3 Only)
- Username: Required for SNMPv3 authentication.
- Context: Optionally specify a context string for SNMPv3 connections.
- Security Level: Choose from noAuthNoPriv, authNoPriv, or authPriv depending on your security needs.
- Auth. Protocol: Select an authentication protocol such as MD5 or SHA.
- Auth. Passphrase: Enter the passphrase for SNMPv3 authentication.
- Privacy Protocol: Choose DES or AES for data encryption.
- Priv. Passphrase: Required for encrypted SNMPv3 communications.
