For logs coming from APM, only the BSD syslog format is supported.
For LTM along with APM deployment, remote syslog configuration is not required. Based on the signatures in the APM, the collector processes only APM logs.
The F5 BIG-IP APM event collector Event Collector supports multiMulti-threading logs from LTM 11.6 to 12.1.1 device also.
Please use below format of iRule if you are using iRule. This is the only format of iRule which we are supporting.
