LPAR2RRD - Dashboard empty

Greg_Chijoff

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)

https://demo.lpar2rrd.com/?menu=0d9795b&tab=0

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,

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
