missing hosts/items

[manowar]

So, I've just had the customer group on the phone because our app died due to out of disk space. Odd I thought, since we've had no alerts.
Checking zabbix, its configured to check all the partition mounts on all our app servers. Checking latest data, seems its actually only checking about 4 items (none of which are disk space) on one machine, and in fact only picking up *anything* from 2 out of the 10 it was configured to.

Anyone any ideas? nothing in the logs, nothing to indicate whats happened or why its shut up shop.

nothing?

I'll rebuild this without the DM being configured and see if it cures it. Dm just seems cursed when its anything more complex than a single parent-> daughter node.
