SNMP Process Event Monitor Reference Guide
notitie
Overview
The SNMP Process Event Monitor utilizes SNMP to connect to network devices and retrieve data about the processes running on them. This tool is particularly useful for ensuring that essential processes are operational and for troubleshooting stopped processes on devices that support SNMP.

Use Cases
- Detecting when specific processes are running or stopped on network devices.
- Monitoring and managing process status remotely via SNMP.
Monitoring Options
SNMP Configuration
- SNMP Version: Choose the appropriate SNMP version (SNMPv1, SNMPv2, or SNMPv3) based on your device configuration.
- Community: Enter the SNMP community string for SNMPv1 and SNMPv2c. The default for read-only access is typically "public".
- Port Number: Standard SNMP port is 161, customizable if your devices use a different port.
- Timeout: Set how long the event monitor waits for a response. Adjustable based on network conditions.
- Retries: Since SNMP uses UDP, configure retries to improve reliability of data retrieval.
Security Settings (SNMPv3)
- Username: Required for SNMPv3 authentication.
- Context: Optionally specify a context string for SNMPv3 connections.
- Security Level: Choose from noAuthNoPriv, authNoPriv, or authPriv, based on your security requirements.
- Auth. Protocol: Select an authentication protocol (MD5, SHA, etc.).
- Auth. Passphrase: Enter the passphrase for SNMPv3 authentication.
- Privacy Protocol: Choose between DES and AES for encrypting SNMP messages.
- Priv. Passphrase: Required for encrypted SNMPv3 communications.

Alerts
- Alert with [Info/Warning/Error/Critical] if specified processes are found to be running: Configure alerts for detected processes that are running.
- Alert with [Info/Warning/Error/Critical] if specified processes are not running: Configure alerts for essential processes that are stopped.
Process Monitoring
- Process Names to Monitor: Enter the names of the processes you want to monitor. If uncertain, run the monitor once to detect and list process names from your devices.
Authentication and Security
- SNMPv1 and SNMPv2c: Requires a community string.
- SNMPv3: Requires a username and additional parameters for enhanced security.
