How to get the "In State" value from the thold page or the host page

[eholz1]

Hello Members,

I would like to get the down time value of a device that registers in the thold-Device Status page.
I seems there is some sort of calculation that the cacti app makes to get this value.

The "In State" field show in the thold_graph.php=hoststat page and the host.php page,

How does cacti get the "In State" value?

Thanks so much,

Cacti knows the last time a device was down by a last error date in the host table.

Both the t hold and monitor plug-in go a little deeper.
