ZenDNN Library Logs

Logging is disabled in the ZenDNN library by default. It can be enabled using the environment variable ZENDNN_LOG_OPTS before running any test. Logging behavior can be specified by setting the environment variable ZENDNN_LOG_OPTS to a comma-delimited list of ACTOR:DBGLVL pairs.

The different ACTORS are as follows.

Table 1. Log Actors
Actor	Description
ALGO	Logs all the executed algorithms.
CORE	Logs all the core ZenDNN library operations.
API	Logs all the ZenDNN API calls.
TEST	Logs all the calls used in API, functionality, and regression tests.
PROF	Logs metadata for the op.
FWK	Logs all the framework (TensorFlow and PyTorch) specific calls.

Example

To turn on info logging, use ZENDNN_LOG_OPTS=ALL:2
To turn off all logging, use ZENDNN_LOG_OPTS=ALL:-1
To only log errors, use ZENDNN_LOG_OPTS=ALL:0
To only log info for ALGO, use ZENDNN_LOG_OPTS=ALL:-1,ALGO:2
To only log info for CORE, use ZENDNN_LOG_OPTS=ALL:-1,CORE:2
To only log info for FWK, use ZENDNN_LOG_OPTS=ALL:-1,FWK:2
To only log info for API, use ZENDNN_LOG_OPTS=ALL:-1,API:2
To only log info for PROF (profile), use ZENDNN_LOG_OPTS=ALL:-1,PROF:2

Enable Log Profiling

To enable the log profiling of zendnn_primitive_create and zendnn_primitive_execute, set ZENDNN_PRIMITIVE_LOG_ENABLE=1

To log performance of operations, use ZENDNN_LOG_OPTS=ALL:-1,PROF:3 along with ZENDNN_PRIMITIVE_LOG_ENABLE=1.

The Different Debug Levels (DBGLVL) are as follows.

Table 2. Debug Levels
Debug Level	Value
`LOG_LEVEL_DISABLED`	-1
`LOG_LEVEL_ERROR`	0
`LOG_LEVEL_WARNING`	1
`LOG_LEVEL_INFO`	2
`LOG_LEVEL_VERBOSE0`	3
`LOG_LEVEL_VERBOSE1`	4
`LOG_LEVEL_VERBOSE2`	5

CORE, API, and PROF are mandatory logs when ZenDNN library is invoked. ALGO, TEST, and FWK are optional logs and might not appear in all the cases.
