Why is the attachment(eg) not showing any data.

You're not going to like this answer, but here it is:

It's not showing any data because it has no data to show.

But that's not really the answer to the question you want to ask. You want to ask, why isn't there any data? There could be a few reasons why:

* The service/host check is not providing any performance data
* The check is providing performance data, but not in a format Nagios recognizes as being numeric and graphable
* The check is failing and not producing any results

Thanks @eloyd!

@ponnpr7, He's right. The check may not be producing any results, but what plugin are you using to check this host?

Also, when you say not showing data. Was there data before? Is this a new host? ( performance graphs may time some time to load if it is producing any results)
