Percona Cacti 0.8.8a - Memory Graph does not exceed 8 GB


I do not know how to change to map the 64 GB and 32 GB RAM of my servers.
The Percona graph is only displaying 8 GB.

If I use then SMNP get info template for memory it is correct.
If I use free -g I obtain the right value.


PMP script gets the memory usage by running “free -ob” and Cacti transforms it in GBs automatically on Memory graph.
I can confirm that even 200+ GBs RAM from a debian server will be shown correctly.
