Hi, i don't get an mailq graph. What is to do?

rrd file will not created I use Hobbit 4.2.0

Part of my hobbitserver.cfg TEST2RRD="cpu=la,disk,inode,qtree,$PINGCOLUMN=tcp,http=tcp,dns=tcp,dig=tcp,time=ntpstat,vmstat,iostat,netstat,temperature,apache,apache1=apache,ntp=clock,bind,sendmail,mailq,nmailq=mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbitd,files,procs=processes,ports,clock,lines,temp,oracle,sar-io,sar-rpca,sar-rqlla,memory,sar-cpu,sar-cswitch,sar-kernel,r-huk24-a,r-huk24-b,r-huk24-c,r-div,r-allianz,r-axakfz,r-directline,r-ineas,r-sdirekt,r-ineas,spam"

This defines which RRD files to include on the "trends" column webpage,

and the order in which they appear.

GRAPHS="la,disk,inode,qtree,files,processes,memory,users,vmstat,iostat,tcp.http,tcp,ncv,netstat,ifstat,mrtg::1,ports,temperature,ntpstat,apache,bind,sendmail,mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbitd,clock,lines,temp,oracle,sar-io,sar-rpca,sar-rqlla,sar-memory,sar-cpu,sar-cswitch,sar-kernel,r-directline,r-huk24,r-huk24b,r-huk24c,r-div,r-allianz,r-axakfz,r-directline,r-ineas,r-sdirekt,response,spam"
