Logging

ACS Logging has two main benefits:

• Provides a standard mechanism for printing log messages
• Logs go to the "Remote Logger" for distribution of logs and storage

Example Logging

• Python

  Code Block
  logger = self.getLogger() logger.logTrace("...") logger.logDebug("...") logger.logInfo("...") logger.logWarning("...") logger.logError("...") #An example logger.info("A real log with a string '%s' and an int (%d)" % ("Log Entry", 3))

• Java

  Code Block
  m_logger.finer("..."); m_logger.fine("..."); m_logger.info("..."); m_logger.warning("..."); m_logger.severe("..."); #An example m_logger.info("A real log with a string '" + "Log Entry" + "' and an int (" + String.valueOf(3) + ")");

• C++

  Code Block
  ACS_TRACE("..."); ACS_DEBUG("..."); ACS_SHORT_LOG((LM_INFO, "...")); ACS_SHORT_LOG((LM_WARNING, "...")); ACS_SHORT_LOG((LM_ERROR, "...")); //An example ACS_SHORT_LOG((LM_INFO, "A real log with a string '%s' and an int (%d)", "Log Entry", 3));

Error Handling

Error Handling in ACS Components has 4 pieces:

• Error Definitions (XML)
• Error Declarations (IDL)
• Throwing Exceptions
• Handling Exceptions
