Nested PVStructureArray With pvput

[William Cork via Tech-talk <tech-talk@aps.anl.gov>]

Hi All,

I’m working on a softIOC that will make calls to a Monit daemon to restart and monitor services under Monit.

Right now, I have the following pv structure (a wip):

test:Monit:localhost structure 
    string host http://localhost:2812
    int poll 120
    structure[] services
        structure 
            string name testService
            boolean monitored true
            int state 0
            string type SERVICE
            epics:nt/NTEnum:1.0 action
                enum_t value
                    int index 0
                    string[] choices ["none", "enable", "disable", "start", "stop", "restart"]

Is it possible to change an element in the nested services list with pvput, or are the immutable?
pvput test:Monit:localhost services='...' may be the wrong syntax?
More precisely, can I change services[index of service I care about].action = "" of the action enums.

Architecturally speaking, is it more ideal to have a bookkeeping PVArray that lists the provided services and individual PVs for each service?

Thanks,
Will
