5 ### `phosphor-gpio-monitor`
7 This daemon accepts a command line parameter for monitoring single gpio line and
8 take action if requested. This implementation uses GPIO keys and only supports
9 monitoring single GPIO line, for multiple lines, user has to run this daemon
10 seperately for each gpio line.
12 ### `phosphor-multi-gpio-monitor`
14 This daemon accepts command line parameter as a well-defined GPIO configuration
15 file in json format to monitor list of gpios from config file and take action
16 defined in config based on gpio state change. It uses libgpiod library.
