How to pass parameters in helpers.cache service command

I am writing a new plugins ... in that I have to call `describeAlarmsForMetric()` and I need to pass paramters
````
var par = {MetricName: p.metricTransformations[0].metricName, Namespace: p.metricTransformations[0].metricNamespace };
```

so I am writing `helpers.cache(cache, cloudwatchlog, 'describeAlarmsForMetric', function(err, data) {`

But I cannot pass the paramters into it. Can you please help me regarding this How can I pass parametrs into this method.

Thanks in advance for help

Start by locating the helpers.cache implementation and existing calls to the describeAlarmsForMetric service command in the plugins. Trace how service arguments are handled and verify the expected parameter behavior; done means the issue has a documented or tested way to pass these parameters.
