Tracking IOPS in Netware 6.5
I need to track the IOPS that our Novell servers are using in order to spec out a SAN solution. I have been unable to find any tools or utilities that would allow me to do that. Does anyone know of a way to monitor disk usage and IOPS?

Investigate SNMP on NetWare 6.5. Use some of the tools found at * http://www.snmplink.org/ *
http://www.novell.com/coolsolutions/appnote/17494.html
SNMPUTIL.EXE is a command line utility (included with the Windows NT 3.51 and 4.0 resource kits) that allows the querying of MIB information from a network device.
Most of the SNMPUTIL command lines below should work, although depending on the OID "leaf" details, it may not return an accurate value. Remember, these are only to help you along with your testing. Each system will be a bit different, and, well, some of the OIDs may not return a value!
Assume a target system IP of 127.0.0.1, with a community name of PUBLIC. Change to your values.
Getting Server Name:
snmputil get 127.0.0.1 public .1.3.6.1.4.1.23.2.28.1.1.0
Getting Server Serial Number:
snmputil get 127.0.0.1 public .1.3.6.1.4.1.23.2.28.1.2.0
Getting IPX Internal Net Number:
snmputil get 127.0.0.1 public .1.3.6.1.4.1.23.2.28.1.3.0
Getting Current Number of Open Files:
snmputil get 127.0.0.1 public .1.3.6.1.4.1.23.2.28.1.7.0
Getting Values for DOS Memory :
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.1
Alloc Memory Pool:
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.2
Cache Buffers (you need to multiply the returned value by 4096 to get the actual value)...
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.3
Cache Moveable Memory (you need to multiply the returned value by 4096 to get the actual value)...
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.4
Cache Non-Moveable Memory (you need to multiply the returned value by 4096 to get the actual value)...
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.5
Code and Data Memory:
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.6
SYS:
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.7
FIRST VOL: (will be SYS on NetWare 3.1x/4/4.1x and NSS_ADMIN on NetWare 5)...
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.8
SECOND VOL:
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.9
THIRD VOL:
snmputil get 127.0.0.1 public .1.3.6.1.2.1.25.2.3.1.6.10

Thank you for the information. But, I don’t see anything here that monitors disk activity. Is there something similar to the iostat or sar activity that I would get on a linux server?
You will need to find the specific OID for disk activity. That is what the SNMPWALK process does. It walks down the OID tree and returns the information from the host. The GETIF utility mentioned on the link provided above is one of the best for walking a tree.
I think I found the two OIDs that I need. They are titled nwFSreads and nwFSwrites. Does anyone know if these are synonymous with disk reads/writes or disk transfers (IOPS)?
Have you perused the tools/utilities that JRB Software offers? He may have what you need.
