Method Details | [hide private]

### __init__(self) (Constructor) | source code
Initializer that takes care of basic daemon options. Creates a PID file. Overrides: ZenUtils.CmdBase.CmdBase.__init__

### _getService(self, name, instance) | source code
Utility method to create the service (like PingConfig) for instance (like localhost) Parameters: `name` (string) - the dotted-name of the module to load (uses @Products.ZenUtils.Utils.importClass) `instance` - string `instance` - each service serves only one specific collector instances (like 'localhost'). instance defines the collector's instance name. Returns: a service loaded from ZenHub/services or one of the zenpacks.

### remote_execute(self, service, instance, method, args) | source code
Execute requests on behalf of zenhub Parameters: `service` (string) - the name of a service, like PingConfig `instance` (string) - each service serves only one specific collector instances (like 'localhost'). instance defines the collector's instance name. `method` (string) - the name of the called method, like getPingTree `args` (tuple) - arguments to the method `kw` (dictionary) - keyword arguments to the method Decorators: `@translateError`

### buildOptions(self) | source code
Options, mostly to find where zenhub lives These options should be passed (by file) from zenhub. Overrides: ZenUtils.CmdBase.CmdBase.buildOptions
