Hi,
A number of our hosts have suddenly got broken graphs for items like:
- Ping Response
- SNMP Response
- Poller Duration
- Running Processes
- Users Logged In
- Context Switches
- System Interrupts
When in debug mode, the graph is showing these errors (depending which graph):
command returned 1 (ERROR: String ends after the = sign on 'CDEF:ping_min=' )
command returned 1 (ERROR: String ends after the = sign on 'CDEF:val_min=' )
command returned 1 (ERROR: String ends after the = sign on 'CDEF:value_min=' )
command returned 1 (ERROR: String ends after the = sign on 'CDEF:users_min=' )
command returned 1 (ERROR: String ends after the = sign on 'CDEF:procs_min=' )
An example of a full string for a broken graph is:

Anyone else seeing this or has our install spontaneously broken itself?
We are at 5910 on Ubuntu 14.04.1 – cheers!
