Platform: Any

Question/Problem Description:

Steps to Reproduce:  
Error Message:  
Defect Number:  
Enhancement Number:  

Graph data for channels in the Monitoring Center are stored in the RRD (round-robin database) files. These files have constant sizes. The size is allocated when a new profile/channel is created.

Sizes are the following:

5-minute channel, flow graph - 15485848 bytes
5-minute channel, NPM graph - 16518160 bytes
1-minute/30-second channel, flow graph - 4670360 bytes
1-minute/30-second channel, NPM graph - 12451920 bytes

Even if NPM/traffic graph is disabled for the channel, both RRD files are created and consume disk space.

GUI (Monitoring Center - Profiles) counts graph data size with fixed values:
31MB per 5-minute channel
17MB per 1-minute/30-second channel

Configuration Center - Resource Manager shows real graph data size on the disk (not the fixed rounded values).
