Simulate Time Faults
This document describes how to use Chaosd to simulate a time offset scenario. You can create experiments either in command-line mode or service mode.
Create experiments using command-line mode
This section describes how to create time fault experiments using commands.
Before creating an experiment, you can run the following command to check the options of time faults:
chaosd attack clock -h
The result is as follows:
$ chaosd attack clock -h
clock skew
Usage:
chaosd attack clock attack [flags]
Flags:
-c, --clock-ids-slice string The identifier of the particular clock on which to act.More clock description in linux kernel can be found in man page of clock_getres, clock_gettime, clock_settime.Muti clock ids should be split with "," (default "CLOCK_REALTIME")
-h, --help help for clock
-p, --pid int Pid of target program.
-t, --time-offset string Specifies the length of time offset.
Global Flags:
--log-level string the log level of chaosd, the value can be 'debug', 'info', 'warn' and 'error'
--uid string the experiment ID
