Sure, I changed swap from 2 GB to 32 GB:

gcc-solaris11# swap -l
swapfile  dev            swaplo      blocks        free
/dev/swap -                  16    67108848    67108848

What is needed to allow munin to run on the Solaris machines? Do you need specific pathes for the tooling?


Best regards
