DFM perfdata expands. How to decrease the perfdata size?

Hi, all.

Our server monitoring system alarmed that my DFM server's disk is reaching full.

I took a look at disk usage under  /opt/<DFM install dir> then found /perfdata consumes 48G.

 

$ sudo du -s -h *

48G     perfdata

 

How can I decrease the perfdata directory size significantly? Could you instruct me a standard steps or give a document link explains the method?

 

Under /perfdata, there are old files which time stamp is older than 1.5 years but those files are quite small. The total size of filers which time stamp is about 50MB.

New time stamp files consumes the space because some of them are larger than 2GB per 1 file.

I checked NMC -> Setup -> Host -> data collection -> Edit

Most objects' setting are below. As I didn't change this setting, this is the default setting. If I change this retention period to 6 months, perfdata decrease?

 

sample period          retention period

1 min                         1.02 year

 

Thank you in advance.

Mariko
