README

ndn-dpdk/core/logger

This package is a thin wrapper of Logrus, a structured logger for Go. C code in this project uses the zf_log library.

Loggers in both C and Go support log level configuration through environment variables. For log module "Foo", the initialization code first looks for "NDNDPDK_LOG_Foo" and, if not found, looks for the generic "NDNDPDK_LOG" environment variable. The value of this environment variable must be one of:

• V: VERBOSE level (C only)
• D: DEBUG level
• I: INFO level (default)
• W: WARNING level
• E: ERROR level
• F: FATAL level
• N: disabled (in C), PANIC level (in Go)

To find all log module names in the codebase, execute:

git grep -E 'INIT_ZF_LOG|logger\.New'
