LPAR2RRD - Dashboard empty

Greetings from Australia team!
I'm an IBMi support engineer, however, self-taught Linux "newb". Please bear with me.  :-)
I have a CentOS7 Linux server and two test AS/400 LPARs communicating on the same subnet:

[lpar2rrd@sdclpar2rrd LPAR2RRD]$ netstat -a| grep 8162
tcp        0      0 0.0.0.0:8162            0.0.0.0:*               LISTEN
tcp        0      1 sdclpar2rrd.sdc.su:8162 pwr50mgt.sdc.sund:19636 LAST_ACK
tcp        0      0 sdclpar2rrd.sdc.su:8162 pwr01mgt.sdc.sund:44003 CLOSE_WAIT
------------------------------------------------------------------------------------------------
Crontab job running hourly:
# LPar2rrd ui
0 * * * * rm -rfv /home/lpar2rrd/LPAR2RRD/data/* && cp -r /LPAR2RRD/data/* /home/lpar2rrd/LPAR2RRD/data
2 * * * * /home/lpar2rrd/lpar2rrd/load.sh >  /home/lpar2rrd/LPAR2RRD/load.out 2>&1 
------------------------------------------------------------------------------------------------
OS/400 Agent Sender jobs running without problem in both LPARs:
    IF: C_SNDSTS  - protocol 5.4 UTF8 conv                                     
    IF: C_SNDSTS  - connection Established() 
------------------------------------------------------------------------------------------------
Telnet jobs tested, but appeared hung - but this could be just the port being blocked for Telnet only traffic:

TELNET RMTSYS('192.168.129.60') PORT(8162) INZWAIT(15) RMTUSER(TESTSTRING) 
Connecting to remote host 192.168.129.60 using port 8162.                  
TELNET session ended.  Connection closed.  

Cause . . . . . :   The session ended because either you quit TELNET, or the 
  remote TELNET server closed the connection in an orderly manner.           
Recovery  . . . :   Start TELNET again.  
------------------------------------------------------------------------------------------------
PROBLEM: I see the 'Table IBM i' Data check show up the LPARs successfully. Machine type, serial number, name,
version 1.1.7, Agents running. All looking good. However - the main Dashboard is empty and does not refresh.
I have not configured any HMCs yet, as I thought they are not mandatory. Should the two HMCs be configured in
order for Dashboard to work?

Thanks and regards,

    Hi,

    1.What is this? Do you remove and copy all data again from somewhere? It makes no sense
    0 * * * * rm -rfv /home/lpar2rrd/LPAR2RRD/data/* && cp -r /LPAR2RRD/data/* /home/lpar2rrd/LPAR2RRD/data

    2. you do not need to connect the HMC, it should work without it, exactly as on our demo where is 1 stand-alone IBM i server (full partition)

    3. send us debug data

    ls -l /home/lpar2rrd/lpar2rrd/data/*/*/*

    Note a short problem description in the text field of the upload form.

    cd /home/lpar2rrd/lpar2rrd  # or where is your LPAR2RRD working dir

    tar cvhf logs.tar logs tmp/*txt tmp/*json

    gzip -9 logs.tar

    Send us logs.tar.gz via https://upload.lpar2rrd.com

    Thanks Pavel, will try and upload log data as directed. 
    As for: 
    0 * * * * rm -rfv /home/lpar2rrd/LPAR2RRD/data/* && cp -r /LPAR2RRD/data/* /home/lpar2rrd/LPAR2RRD/data

    Yes, a little strange. I think when I moved my LPAR2RRD directory the 'symbolic' links were lost. The copy function ensures the correct '/data' directory is from the IBMi connections.
    regards,
    Greg

    some sort of symlink would solve that, this is not nice solution
    like this, I hope I am correct based what I see above
    ln -s /LPAR2RRD/data /home/lpar2rrd/LPAR2RRD/data

    suppose  /home/lpar2rrd/LPAR2RRD/data is removed before
