When implementing a large QRadar environment we can face several types of log sources across the network. QRadar support more than one hundred type of devices out-of-the-box and can integrate with any another log source using customized parsers. The log source parsers are known in QRadar as Device Support Modules (DSMs).
A personal recommendation to integrate log sources with QRadar is: always use syslog when it is possible. Why? Basically syslog is the standard log protocol for many devices, and QRadar can easily collect, identify and receive logs using this protocol. The syslog typically uses UDP connections, so make the log collection more fast and with almost zero latency. Make sure that all the firewalls of your environment allow traffic to QRadar in the port 514 (default syslog port).
IBM provide a good documentation explaining thorougly how to configure each type of device to send logs to QRadar. You can find the DSM configuration guide in the following link:
