Release Information

Statement introduced in Junos OS Release 16.1.

Trace flag options libgrpc-debug, libgrpc-errors, and libgrpc-info are supported in Junos OS Release 19.3R1 only.

Description

Define tracing operations for the JET service process (jsd).

Options

fileIndicate trace file information.
filenameName of the file to receive the tracing operation output. Enclose the name in quotation marks. Traceoption output files are located in the /var/log/ directory.
files number(Optional) Specify the maximum number of trace files.

Range: 2 through 1000

Default: 10

match regexSpecify the regular expression for lines to be logged.
size size(Optional) Specify the maximum size of each trace file. When a trace file named trace-file reaches its maximum size, it is renamed trace-file.0. The traceoption output continues in a second trace file named trace-file.1. When trace-file.1 reaches its maximum size, output continues in a third file named trace-file.2, and so on. When the maximum number of trace files is reached, the oldest trace file is overwritten.

Range: 10,240 through 1,073,741,824 bytes

Default: 1000k

world-readable | no-world-readable(Optional). Grant all users permission to read log files, or restrict the permission only to the root user and users who have Junos OS maintenance permission.
flag flagSpecify the tracing operation to perform. To specify more than one tracing operation, include multiple flag statements:
  • all—Trace everything.

  • config—Trace configuration events.

  • general—Trace general events.

  • grpc—Trace grpc server events.

  • libgrpc-debug—(Junos OS Release 19.3R1 only) Trace all lib grpc-related events.

  • libgrpc-errors—(Junos OS Release 19.3R1 only) Trace lib grpc errors.

  • libgrpc-info—(Junos OS Release 19.3R1 only) Trace lib grpc info and errors.

  • notification—Trace notification events.

  • routing-socket—Trace routing socket calls

  • timeouts—Trace timeouts.

  • timer—Trace internal timer events.

Note

The libgrpc traceoptions are only supported in Junos OS Release 19.3R1. They allow you to see events from the grpc libraries in the jsd trace log. Within the grpc core there are multiple libraries (for example, iomgr, compression, and profiling).

no-remote-traceDisable remote tracing.
