Documentation for Splunk O11y Workshop - zPages

For the OTel Collector Sec 2 Extensions - zPages, it is important to highlight that port 55679 needs to be whitelisted in order for the zpages to be loaded.

For ie, if one is running EC2 instance in AWS , then port 55679 needs to be explicitly enabled in the Security Group attached to that EC2 instance.

See screenshot below of a Security Group settings with port 55679 whitelisted.

OK, so the official terraform for creating EC2 instances has both 55679 and 13133 (Health check) opened.
