What could be the reason for Dash (no value) in the availability of a software service?

I see dash in the availability, what does it means? what is possibly causing this?

No measurement performed for the server in this time period?

Availability is measured as the percentage of successful TCP connection attempts. If no connection attempt has been made, then no measurement were performed. Please note that an existing session may be opened and active, but it wouldn't count as an availability measurement.

You can easily examine this theory by adding metrics like number of bytes, packets, TCP connection attempts, TCP errors en masse or by category.

Hope this helps.
