10.3.146.165


Study gnmi openconfig

Need to build on top of it: (Upgrade mops gnmi diskspace)
https://github.com/sonic-net/sonic-gnmi/pull/462/files

https://github.com/sonic-net/sonic-gnmi/pull/459
Entry point is server->main.go (no need to change it)

For file remove

EnableGNOISystem() --> Existing
EnableGNOIFile()  --> create this new function


In file: sonic-gnmi-standalone/pkg/server/builder.go

Existing:
	// Register gNOI System service
	if b.services["gnoi.system"] {
		systemServer := gnoiSystem.NewServer(rootFS)
		system.RegisterSystemServer(srv.grpcServer, systemServer)
		glog.Info("Registered gNOI System service")
		serviceCount++
	}

New:
if b.services["gnoi.file"]


The main entry point is: sonic-gnmi-standalone/pkg/server/gnoi/system/system.go
Copy this file


After this PR https://github.com/sonic-net/sonic-gnmi/pull/462/files is merged:
you need to change only: sonic-gnmi-standalone/pkg/server/gnmi/path_utils.go


Will have to create one similar to this:
sonic-gnmi-standalone/pkg/workflow/steps/check_disk_space.go

type CheckDiskSpaceStep struct {


Add the implementation here:
sonic-gnmi-standalone/pkg/server/gnmi/get.go

To invoke you can use loopback test or actual function
