LUN2 returns 14%, but only 9% are free. That's just wrong
If you provide HTTPS access to MOB, we can check what is wrong.
Unfortunately, I do not quite understand how to set up the SNMP test.
Not SNMP test, Drive Free Space test (SNMP mode).
If you click Help button or press F1, HostMonitor will tell you everything about test settings.
Target host
Provide host name, IPv6 or IPv4 address (e.g. 10.10.1.55) of the system that you wish to monitor.
Optionally you may specify UDP port; port number has to be provided after a colon following the address(hostname) (e.g. 172.168.10.10:161).
SNMP profile
Choose profile that stores credentials necessary for communication with SNMP agent on target system. You may select profile from drop-down list or click button beside the list to bring up SNMP Credentials dialog.
Note: HostMonitor may retrieve data faster when SNMP v2c or SNMP v3 is used.
Timeout, Retries
...
Then you may select one or several of the following options
- Check all local drives tells HostMonitor to check all fixed drives on target system
- Check all removable drives check all removable drives on target system (not including CD/DVD drives)
- Check listed drive(s) mark this option and provide drive list when you want to check specific drive(s) on target system, e.g. /var /dev/sda/. Note: wildcard * can be used at the end of disk name, e.g. /dev/sd*
Alert if free space less than <N> MB/GB/TB/%
When HostMonitor checks several drives it finds drive with smallest amount of free space (or drive with minimal percentage of free space when "%" alert options is selected) and sets Ok or Bad test status depending on amount of free space and value of this option.
Also %DiskID% and %DiskLabel% variables can be used as parameters of the actions, providing information about target drive.
Then you need to read HP 3PAR manual and setup SNMP agent on this device. Probably SNMP agent already active, you may try "public" as default community name.
