Syslog vs SNMP

Syslog and SNMP are both used for monitoring and troubleshooting of devices. They are complementary, but their functionalities are different.

Syslog is used for message logging.

  • Event that occur within the system are categorized based on facility/severity and logged.

  • Used for system management, analysis, and troubleshooting.

  • Messages are sent from the devices to the server. The server can't actively pull information from the devices (like SNMP Get) or modify variables (like SNMP Set).

SNMP is used to retrieve and organize information about the SNMP managed devices.

  • IP addresses, current interface status, temperature, CPU usage, etc.

  • SNMP servers can use Get to query the clients and Set to modify variables on the clients.
