LPAR2RRD 7.5-7,7.10-1: Broken LPAR CPU Graphs

snyckau · April 2021

Hi,

we query data for lpar2rrd from a vCenter, some unmanaged LPARs via OS agent and via HMC SSH.
I noticed that for the LPARs queried via HMC the CPU graphs are not working:

E.g. for this LPAR ("AUEPPDB01") some rrm files are present:
lpar/data/<lpar_serial>/192.168.81.130/AUEPPDB01.rrm
lpar/data/<lpar_serial>/192.168.81.130/AUEPPDB01.rrm
lpar/data/<lpar_serial>/192.168.81.130/AUEPPDB01.rrm

But not in the expected vmware_VMs folder. I tried setting up a hardlink manually but this resulted in the error "No DS called 'CPU_Alloc'.

Also the CPU Pool for the managed systems queried via HMC:

The only suspicious thing I found was this in load_power.log:
skipped this time : ( 1619165993 - 1619156980 ) < 18000
skipped this time : ( 1619165993 - 1619138982 ) < 39600
skipped this time : ( 1619165993 - 1619103011 ) < 86400

I ran version 7.5-7 first and tried the latest version 7.10-1 now but that did not change anything.

Can you please advise?

Thank you,
Christoph

Hi,

send us current logs please.

cd /home/lpar2rrd/lpar2rrd; #or your LPAR2RRD dir

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

gzip -9 logs.tar;

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

Hi Jan,

I've uploaded the logs as requested and mentioned this thread in the description.

Hi Jan,

did you have a chance to look at this already?

Thank you

This was solved via mail. In case anyone else has this problem, this was the solution:

su - lpar2rrd
cd lpar2rrd
ls -l data/*/*/vmware.txt

(this returned a lot of "vmware.txt" files which shouldn't be the case according to support)

rm data/*/*/vmware.txt
