Nagiosgrapher problem with building graph for particular check_service

[yuris]

Hi all,

I use check_milter which is basically check_tcp with some arguments, it 
gives output like this:

TCP OK - 0.002 second response time on port 
1313|time=0.001912s;;;0.000000;10.000000

it's very similar to output from check_ldap:

LDAP OK - 0.006 seconds response time|time=0.006278s;;;0.000000

I have defined ngraph for check_milter very similar to check_ldap:

define ngraph{
        service_name              Milter
        graph_perf_regex        time=\s*([0-9.]+)
        graph_value                sec
        graph_units                 second
        graph_legend              response time on port 1313
        rrd_plottype                LINE2
        rrd_color                    0000ff
        }

define ngraph{
        service_name               LDAP
        graph_perf_regex        time=\s*([0-9.]+)
        graph_value                sec
        graph_units                 seconds
        graph_legend              LDAP Response time
        rrd_plottype                LINE2
        rrd_color                     00a000
        }

And the problem is that graphs for Milter are not shown, Nagiosgrapher 
complains that "some error occured":

RRD Error: No DS called 'sec' in 
'/var/lib/nagiosgrapher/rrd/<hostname>/457eb765jjf8905k0000567849c.rrd'

I wonder why "graph_value sec" is ok for LDAP graph but does not suit 
for different service with almost identical output?

and I see no errors in ngraph.log:

2010-07-09 08:32:55 PIPE: node142       Milter  TCP OK - 0.050 second 
response time on port 1313        time=0.049644s;;;0.000000;10.000000n
2010-07-09 08:32:55 VALUES: [node142][Milter]: sec=0.049644
2010-07-09 08:32:55 RRD: rrdtool update 
/var/lib/nagiosgrapher/rrd/node142/4bab581d80135b9823fd2a54001423a4.rrd 
--template=sec N:0.049644

Please help me figure out what's wrong did I do?
