Hi:
I have a problem with calculated items:
I have monitored a router interface (SNMP in/out traffic items) and also have a graphic for those items in a host. The delay for those items is 60 seconds.
At the same time, we have two items (in another host) that theirs values are calculated items from the router items "last(Router:item)". The delay for these items is 300 seconds. Also, this host has a graph associated with these items.
Yesterday, the router went down and the graph associated with the router draws a "blank" during the time the router went down, but, the other host, with calculated items, draws a line between the missing values, like an avg value.
I using the same zoom time and time period for drawing so I think it shouldn't be a problem with history and trend values.
This is an unwanted behaviour for us, so, am I doing anything wrong?
Thanks.
