/**
|
|
* PSStatus Plugin, which displays the status of configured processes
|
|
* a simple view which shows a process name and the status
|
|
* status determined by calling the "pidof" command line utility, another way is to provide
|
|
* a file with the output of the pidof utility, so there is no need to run a executeable by the
|
|
* webserver, the format of the command is written down in the phpsysinfo.ini file, where also
|
|
* the method of getting the information is configured
|
|
* processes that should be checked are also defined in phpsysinfo.ini
