Compaq TCP/IP Services for OpenVMS Programming And Reference Manual page 127

TCP/IP Services does not support writing log files to locations other than the
SYS$SYSDEVICE:[TCPIP$SNMP] directory.
The log files contain startup and event information and additional messages,
depending on the logging level specified for an agent. The SNMP logging facility
uses three logging levels:
• TRACE (logs trace, warning, and error messages)
• WARNING (logs warning and error messages)
• ERROR
For the master agent and standard subagents, the logging level is WARNING.
Log files for these processes include messages for WARNING and ERROR
events. The chess example does not have a default log level. Therefore, no log
messages appear. To specify a default log level for custom subagents, you can use
the standard API call
set_debug_level
Because the chess example subagent does not use a default, messages are
captured only if you specify tracing. For information about getting trace logs,
refer to the Compaq TCP/IP Services for OpenVMS Management guide.
