Items and Triggers not shown

[Barclay]

Hello,
I have a problems with items and trigger which are not shown in the Monitoring overview. They also dont appear in menus like the one in which you can choose items for showing in screens.
I cant figure out why some items are shown on others are not. Anyone an idea what can cause such things?

I am runing 1.4.6 of the debian sources on debian lenny.

They're probably disabled or unsupported.

Go configuration->items and select the host group and host you want, and make sure to click on 'show disabled items' if you see that next to the host groups (should say 'hide disabled items'). Then look at the 'Status' and 'Errors' columns for the items that aren't showing up.

Try selecting any items which don't have a green 'Active' under the 'Status' line via the radiobuttons on the far left hand side and at the bottom of the screen do an 'Activate Selected' and then wait ~60 seconds or whatever your update interval is. If they re-disable themselves then you need to debug why they're being disabled -- could be a typo in the item, could be throwing errors into the zabbix logs, could be that you've got the wrong "type" for the item (e.g. Zabbix Agent vs. Zabbix Trapper) or the wrong "type of information" for the item (e.g. trying to push floating point values onto an item configured as an integer will fail).

If you've got items configured that aren't supported by the agent (e.g. you've got vfs.dev.read[sda1,sectors] on a server that doesn't actually have a /dev/sda1) then the item will show a ZBX_NOT_SUPPORTED in the Errors column and it won't show up in a lot of other lists. That is how it is supposed to work though. That lets you drop uniform templates onto servers that might differ slighly in how their disks are configured and you and zabbix both ignore the items that aren't relevant for the individual server.

Thank you, this explanation makes complete sense and the problem is solved
