SNMP Event Monitor Reference Guide

notitie

Overview​

The SNMP Event Monitor tracks a variety of values from your networking equipment and other devices that support SNMP. It simplifies SNMP monitoring by allowing the use of either numeric OIDs or symbolic names, providing flexibility depending on the presence of MIBs.

info

Use Cases​

  • Monitoring custom SNMP values on networking equipment.
  • Enhancing network management through detailed SNMP insights.

Monitoring Options​

Configuration​

  • SNMP Version: Choose between SNMPv1, SNMPv2, and SNMPv3 based on device compatibility.
  • Community: Enter the community string for SNMPv1 and SNMPv2c; "public" is commonly used for read-only access.
  • Username (SNMPv3 Only): Specify the username for SNMPv3 connections.
  • Port Number: Default is 161, change if your devices use a different port.
  • Timeout and Retries: Set how long to wait for a response and the number of retry attempts.

Security (SNMPv3)​

  • Context: Optionally specify a context string required for the SNMPv3 connection.
  • Security Level: Choose from noAuthNoPriv, authNoPriv, or authPriv based on your security needs.
  • Auth. Protocol: Select an authentication protocol like MD5 or SHA.
  • Auth. Passphrase: Enter the passphrase for authentication.
  • Privacy Protocol: Choose DES or AES for data encryption.
  • Priv. Passphrase: Enter the passphrase for privacy encryption.

Monitoring Specifics​

  • Items to Monitor: Enter either the numeric OIDs or symbolic names to be monitored.
  • Label: Provide a friendly name for each OID/symbolic name for clarity in alerts and notifications.
  • Comparison and Value: Define the criteria for generating alerts based on the monitored values.
  • Data Type, Scale, and Postfix: Configure how numeric values are formatted and displayed.

Advanced Table Monitoring​

  • SNMP Tables: Specify how to monitor values within SNMP tables, using a unique approach to labeling using other table items as descriptors.

Authentication and Security​

  • Authentication: Requires a community string for SNMPv1 and SNMPv2c, and a username along with other parameters for SNMPv3.
