file (App Engine Virtual Machine Management Service)

Name of the file in which the trace information is stored. By default, the file is created in the /var/log directory.

(Optional) Maximum number of trace files. When a trace file reaches the size specified by the size option, the filename is appended with 0 and compressed. For example, when a trace file named trace-file-log reaches size size, it is compressed and renamed as trace-file-log.0.gz. When trace-file-log reaches size size for the second time, trace-file-log.0.gz is renamed as trace-file-log.1.gz and trace-file-log is compressed and renamed as trace-file-log.0.gz. This renaming sheme ensures that the older logs have a greater index number. When number of trace files reaches number, the oldest file is deleted.

If you specify a maximum number of files, you also must specify a maximum file size with the size option and a filename.

• Range: 2 through 1000

• Default: 10

Refine the output to include only those lines that match the given regular expression.

Restrict file access to the user who created the trace files.

Maximum size of each trace file . By default, the number entered is treated as bytes. Alternatively, you can include a suffix to the number to indicate kilobytes (KB), megabytes (MB), or gigabytes (GB). If you specify a maximum file size, you also must specify a maximum number of trace files with the files option.

• Range: 10 KB through 1 GB

• Default: 128 KB
