Graphs for one host don't show?

[ansabhailte]

Hey guys,

I'm having a problem where my graphs for one of the hosts I'm monitoring don't appear in the graphs.

Here is the relevant part of the log file: http://pastebin.com/yqdSCrfM

This started when I tried to bulk add hosts through CLI. The command I used for one host was this:

php -q add_graphs.php --graph-type=ds --host-id=26 --graph-template-id=32 --snmp-query-id=1 --snmp-query-type-id=21 --snmp-field=ifIndex --snmp-value=10101

Any help is greatly appreciated. Thanks!

edit: This problem also persists for two checks I configured the normal way through the web interface, on the same host. (Cisco CPU and Mem)

Well, the log file does not help.
What was the output when running the given command?
