Problem with (null) result

[reincarne]

Hi,
I'm running a plugin that checks Graphite server.
In general you provide to Nagios a specific metric to run on the Graphite server and it returns back a result.
For some reason, when I run the specific metric below, Nagios does run and return a normal result (when I run it through "Test Check Command"), but once I apply the configuration and go to my dashboard,
it shows (null) under the Status Information.
sumSeries(group(stats_counts.sts.api.post.issue.*.*.error,stats_counts.sts.api.post.issue.*.error))

If I run simple metrics, there is no problem ==> exaple: stats_counts.sts.api.post.issue.*.*.error
I think the problem is with the brackets.

Do you have any idea what could be the problem?
Thanks.

Can we see the command definition for this check and the service you have this on? CCM > Services > 'click the blue diskette icon next to the service's name and paste the output here, in code wraps' Please do the same for the command definition under CCM > Commands. When you manually run this check from the command line what is returned? Thanks!
