SNMP Get tune up Value from * TB or * GB

Celay · Post by **Celay** » Mon Jan 08, 2018 10:44 am

Hello,

im currently trying to monitor the free space of different RAIDs on multiple NAS (different Qnap models), sadly the Qnap returns a value of GB or TB (i.e. 325 GB or 3.25 TB) instead of Byte, right now I have the Monitoring setup to warn me if the space goes below 300GB, this works fine until the NAS gets free space above 1 TB because the HM interprets it like 1 is < 300, I have tried to play with the Tune up Reply value a bit but couldn't figure out how to change the reply to either byte or make a difference between GB or TB Replys, is there any way to do that?

Thanks in advance
Celay

HostMonitor does not support QNAP devices yet (does work with NetApp).
What test method do you use? SNMP Get? SNMP Table? SNMP Trap? some other?
HostMonitor version?
What exactly expression do you use?

If device returns "1 TB" string and you are using option like Set Normal status if '%SuggestedReply%' > '300 GB', it should work properly

First of all thanks for the fast answer.

Im using SNMP Get with the expression IF OID 1.3.6.1.4.1.24681.1.2.17.1.5.2 (stands for "sysVolumeFreeSize.1") is < than 300.00 GB (I tried 300 GB, 300.00 and 300 all have the same outcome I guess the GB simply gets ignored?)

HostMonitor version is v9.38.

9.38 too old, we do not support it anymore.
If you specify '300 GB' for SNMP check it will be compared as string.
If you use '300 GB' for Optional status processing expressions, then it will be compared as number

E.g. you may use option like Set Normal status if '%SuggestedReply%' > '300 GB'
