RE: change priority of tasks in cfagent

[Wheeler, John]

I started to formulate a solution based on fiters:
control:
        Verbose = ( on )
        actionsequence = (
                        shellcommands
                        processes
                        shellcommands
                        )

processes:
        SetOptionString "-elf"
        "cfagent"
                filter=renicecfagent

shellcommands:
        '/bin/ps -elf |grep cfagent'

filters:
        { renicecfagent
                Priority: "20"
                Result: "Priority"
        }


started to test it but:

looks like I did something "bad". It found the priority. If you can get
this to work, the next step would be to enable a class and have shell
commands renice the process. You may even be able to renice it from the
filter itself with something like
ExecProgram: "/bin/nice $(this)"       # True if the program returns
true. $(this) is the current object

Gave up. ;-(
