CPU Total history missing after 6.15 -> 7.60 upgrade

hab

We upgraded our LPAR2RRD server yesterday from 6.15 on SLE 15 SP1. First to SLE 15 SP3 and then LPAR2RRD from 6.15 to 7.60.

The server is collecting and presenting new data just fine, but the "CPU Total" data from before the upgrade is missing (on the menu item directly below each server in the SERVER menu.

It seems that the history data is available on other graphs, we can see them in default pool and lpars aggregated.

We received a lot of these on the first run of load.sh (./load.sh 2>&1 | tee logs/load.out-initial) :

[Wed Apr 26 10:10:06 2023] prediction.pl: Use of uninitialized value $val in subtraction (-) at /home/lpar2rrd/lpar2rrd/bin/Prediction.pm line 545.

[Wed Apr 26 10:10:06 2023] prediction.pl: Use of uninitialized value $val in subtraction (-) at /home/lpar2rrd/lpar2rrd/bin/Prediction.pm line 547.

Not sure if that is related or not.

Any idea if and how this can be fixed? Thanks.

Hi,

this is a new graph, new data, before main CPU graph was CPU pool, however it does not include CPU dedicated LPARs load.

You can see that you have all history in CPU pool graph.

I didn't realize it was new :)

You are correct, thank you for pointing that out.
