能否为Autosys作业错误日志添加时间戳？含STDERR重定向场景

Question 1: Can timestamps be added to Autosys job error logs? #

Absolutely, you can add timestamps to Autosys job error logs using a couple of straightforward methods:

• Modify the job command to prefix output with timestamps: Instead of letting the job write raw stderr output, pipe it through a utility that adds timestamps. For example, if your job runs a shell script, adjust the command like this:

  ./your_job_script.sh 2>&1 | awk '{ print strftime("[%Y-%m-%d %H:%M:%S]"), $0 }' >> JOB_NAME.ERR
  

  This redirects both stdout and stderr to awk, which prepends a formatted timestamp to each line before writing to the error file.

• Leverage Autosys built-in logging (version-dependent): Some newer Autosys releases include enhanced logging options that support timestamps. Check your environment's documentation for settings like log_file with timestamp parameters, or use the autorep command with flags to view logs with timestamps. Note this varies by Autosys version, so verify with your setup.

Question 2: Can timestamps be added to Autosys job error files using only STDERR redirection (configured as std_err_file: >>JOB_NAME.ERR)? #

No, relying solely on the std_err_file configuration won't automatically add timestamps to the error log. This setting just redirects the raw stderr output of the job to the specified file—there's no built-in logic to prepend timestamps at this level.

To get timestamps while still using stderr redirection, you need to adjust the job's command to process output before it's written to the file. For example:

• Use the ts utility (common on Unix-like systems) for simple timestamping:

  your_job_command 2>&1 | ts "[%Y-%m-%d %H:%M:%S]" >> JOB_NAME.ERR
  

• Or stick with awk for more control over the timestamp format:

  your_job_command 2>&1 | awk '{ print strftime("[%Y-%m-%d %H:%M:%S]"), $0 }' >> JOB_NAME.ERR
  

You can either include the redirection directly in the command, or keep std_err_file configured and pipe stderr through the timestamp tool before it's captured by Autosys. Either way, the timestamping logic has to be part of the job's execution command—it can't be done only via the std_err_file parameter.
