confused by proc.mem returned value

[chriso]

I am using Zabbix 1.8.2 on Solaris 10

If I do a prstat to show top processes, I get:
1321 co 22G 20G sleep 59 0 141:35:09 14% java/135
1620 co 538M 518M sleep 59 0 19:42:37 0.4% java/30
1276 co 782M 776M sleep 59 0 16:38:00 0.3% java/89
1209 co 1156M 1129M sleep 59 0 7:31:46 0.2% java/51
1579 co 559M 553M sleep 59 0 19:34:22 0.2% java/39
1611 co 471M 458M sleep 59 0 13:01:01 0.1% java/33
1234 co 645M 580M sleep 59 0 3:24:02 0.1% java/48
1286 co 412M 402M sleep 59 0 0:37:55 0.0% java/36
1632 co 587M 202M sleep 59 0 0:17:53 0.0% java/21

These are all java processes. The fourth column is RSS (resident) memory.

When I do a proc.mem(java), I get: 5842051072. I've tried setting my Units to b and B. I can't convert this value to anything reasonable. The proc.mem should return something around 25gig.

Thanks for any help.

Well I'll just answer my own question. Based off this thread, proc.mem really doesn't return anything useful. RSS would be much more useful than VSZ.

After some further research..PID 1321 from my first post:

1321 co 22G 20G sleep 59 0 141:35:09 14% java/135

..is a 64 bit process. Apparently zabbix 32-bit cannot "read" a 64 bit process. Or...solaris is not letting zabbix use this value until I re-build zabbix for 64 bit.
