hi After upgrading the observium it show all device down. When i run the discovery it shows as follow.

Observium v0.12.3.2901 Discovery

MySQL: Cell[1/0s] Row[1/0s] Rows[1/0s] Column[0/0s] Update[0/0s] Insert[0/0s] Delete[0/0s]

Any fix?

I encountered this when i upgraded a CentOS host to r2891 this week. I found that the call to snmpget from poller.php was failing with the error message "add_mibdir: strings scanned in from /opt/observium/mibs//.index are too large". Check your poller.php; if this is your problem, the solution is to remove the file mentioned - i believe snmpget rebuilds it or works around its absence automatically. Tom may be able to shed some more light on why this is the case.

I found that after this upgrade and fixing the index error, polls seemed to take a lot longer. In my case, i had to double the number of pollers running in parallel from 4 to 8 in order to achieve similar overall performance.

Hope this helps,
Paul
