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:

graph /tmp/0H1FmUUbABhyOl7U.png --alt-autoscale --rigid --start 1414240174 --end 1414326574 --width 1159 --height 300 -c BACK#EEEEEE00 -c SHADEA#EEEEEE00 -c SHADEB#EEEEEE00 -c FONT#000000 -c CANVAS#FFFFFF00 -c GRID#a5a5a5 -c MGRID#FF9999 -c FRAME#5e5e5e -c ARROW#5e5e5e -R normal --font LEGEND:8:'DejaVuSansMono' --font AXIS:7:'DejaVuSansMono' --font-render-mode normal -E COMMENT:' ' COMMENT:' Now' COMMENT:' Avg' COMMENT:' Min' COMMENT:' Max' COMMENT:' Total' COMMENT:'\l' DEF:procs=/opt/observium/rrd/hostname.was.here/hr_processes.rrd:procs:AVERAGE CDEF:procs_min= CDEF:procs_max= AREA:procs#E881B1:"Processes " LINE1.5:procs#744058 GPRINT:procs:LAST:%6.1lf%S GPRINT:procs:AVERAGE:%6.1lf%S GPRINT:procs_min:MIN:%6.1lf%S GPRINT:procs_max:MAX:%6.1lf%S COMMENT:'\l'

Anyone else seeing this or has our install spontaneously broken itself?

We are at 5910 on Ubuntu 14.04.1 - cheers!
