DISMAN-SCRIPT-MIB::smScriptAbort #

This notification is generated whenever a running script terminates with an smRunExitCode unequal to `noError'.

Variables #

• smRunExitCode
• smRunEndTime
• smRunError

Definitions #

smRunExitCode

The value of this object indicates the reason why a script finished execution. The smRunExitCode code may have one of the following values:

• `noError’, which indicates that the script completed successfully without errors;
• `halted’, which indicates that the script was halted by a request from an authorized manager;
• `lifeTimeExceeded’, which indicates that the script exited because a time limit was exceeded;
• `noResourcesLeft’, which indicates that the script exited because it ran out of resources (e.g. memory);
• `languageError’, which indicates that the script exited because of a language error (e.g. a syntax error in an interpreted language);
• `runtimeError’, which indicates that the script exited due to a runtime error (e.g. a division by zero);
• `invalidArgument’, which indicates that the script could not be run because of invalid script arguments;
• `securityViolation’, which indicates that the script exited due to a security violation;
• genericError', which indicates that the script exited for an unspecified reason. If the script has not yet begun running, or is currently running, the value will be noError'.

smRunEndTime

The date and time when the execution terminated. The value ‘0000000000000000’H is returned if the script has not terminated yet.

smRunError

This object contains a descriptive error message if the script startup or execution raised an abnormal condition. An implementation must store a descriptive error message in this object if the script exits with the smRunExitCode `genericError’.

Meaning #

The DISMAN-SCRIPT-MIB::smScriptAbort notification is triggered when a running script terminates with an smRunExitCode that is not equal to ’noError’. This means that the script has completed execution with an error or abnormal condition.

Impact #

The impact of this notification can vary depending on the specific error code and the importance of the script to the system. However, some possible impacts include:

• Interrupted automation: If the script was performing critical automation tasks, its abrupt termination could lead to incomplete or inconsistent system configuration.
• Data loss or corruption: Depending on the script’s function, its termination could result in incomplete or corrupted data, leading to system instability or errors.
• System instability: In extreme cases, the script’s termination could cause system crashes or freezes, leading to downtime and impacting user productivity.

Diagnosis #

To diagnose the root cause of the smScriptAbort notification:

1. Check the smRunExitCode value to determine the reason for the script’s termination.
2. Examine the smRunError object for a descriptive error message, especially if the smRunExitCode is ‘genericError’.
3. Verify the script’s execution history, including the smRunEndTime, to identify any patterns or trends in script failures.
4. Investigate system logs and event logs for any related errors or warnings that may indicate the underlying cause of the script’s termination.

Mitigation #

To mitigate the effects of the smScriptAbort notification:

1. Implement script retry mechanisms to automatically restart the script if it terminates abnormally.
2. Configure script timeouts and execution limits to prevent resource exhaustion and minimize the impact of script failures.
3. Monitor script execution and detect anomalies using tools such as logging, auditing, and performance monitoring.
4. Develop and implement robust script error handling mechanisms to catch and handle runtime errors, language errors, and other script-related issues.
5. Regularly review and update scripts to ensure they are functioning as intended and are not contributing to system instability.
