SNMP vs SYSLOG

Comparison Table: SNMP vs Syslog

Below table summarizes the main differences between SNMP and Syslog:

S.No.	SNMP	SYSLOG
1	SNMP allows for remote monitoring of SNMP-Allowable device on network.	SYSLOG is a different protocol that can be used for exchanging log messages of varying degrees of severity to network device capable of receiving syslog messages.
2	SNMP is used to alert on critical actions, like the mentioned HSRP state changes.	SYSLOG is also collected, which allows me to dig deeper to figure out why the HSRP state change occurred.
3	SNMP works on Poll – Resource mechanism with SNMP Server polling the device for response on interface/ health /process.	SYSLOG works on PUSH mechanism on end device to send logging information.
4	SNMP is referred to get real time information.	SYSLOG is generally referred to acquire historical data.
5	End device configuration can be performed via SNMP set. E.g.: Reboot system	End device configuration cannot be performed via syslog set.
6	SNMP traps are shared in binary format.	Syslog events are shared in plain text.
7	Secure	Insecure
8	Active	Passive
9	Uses UDP port numbers 161 and 162.	Uses TCP/UDP port number 514
