Extracting a value from an OID - Zabbix 6.0.2

[MonZabbix]

Hello everyone,

I'm using Zabbix for a couple months now and I'm loving it!

I'm currently struggling on the making of a template for a Lenovo DS4200 SAN.

I have got an OID that is giving me mutiples values and I want to only have one of the 3 values that this OID is giving me.

I tried to find trough the Zabbix forums and documentations but I didn't find anything related to my problem.

One of the results of my snmpwalk of the OID .1.3.6.1.3.94.1.8.1.6 from the FCMGMT-MIB::connUnitSensorMessage:

.1.3.6.1.3.94.1.8.1.6.32.128.0.192.255.67.127.117. 0.0.0.0.0.0.0.0.1 = STRING: "CPU Temperature-Ctlr B: 64 C 147.20F"

The only value I want is the "64 C" from the value "CPU Temperature-Ctlr B: 64 C 147.20F"

Because right now in Zabbix the value is listed like this:



I did a discovery rule of this OID that is listing me around 40 items and most of them are temperature items.

What should i do in Zabbix to only have the "C" value for each item in my discovery rule ?

Thank you everyone.

Following, if only because I have similar SANs that will soon be interesting to bring into Zabbix.

Try using regular expressions in Preprocessing.

ex.
pattern:
CPU Temperature-Ctlr [A-Z]: ([0-9].*) C
output:
\1

Yeah.. What Atsushi said...

Hello everyone!
Thank you for the quick reply!

Unfortunately, this doesn't seem to be working...



Sample of the results of clicking on Test:

{"{#SNMPINDEX}":"32.128.0.192.255.67.127.117.0.0.0 .0.0.0.0.0.7","{#CONNUNITSENSORNAME}":"CPU Temperature-Ctlr A","{#CONNUNITSENSORMESSAGE}":"CPU Temperature-Ctlr A: 64 C 147.20F"}

When i go in last value, It is still the same result too:



Hope i gave enough information. Thanks for the hint though! I will do some research about the preprocessing rule.

Did you set the regular expression and then save the setting?

[MonZabbix]

Did you set the regular expression and then save the setting?

Yes I did, i even "executed now" the discovery rule then I executed the Cpu Temperature Ctrl A & B items and yeah still the same results on the last value...

I will dig and try to find a solution, I will keep you guys updated if I find it, thanks!

If it is the item to be discovered, set the location to be set in the item prototype of the discovery rule. It is not set for discovery rules.

If it is the item to be discovered, set the location to be set in the prototype of the item of the discovery rule. It is not set for discovery rules.

Thank you for the information Atsushi, I actually didn't know where to place it so I made the rule on both the discovery rule and the prototype of the item.

It is now working , thank you so much Atsushi! I just need to do the preprocessing rule for all of the others items now and I should be ok!

Hi, do you still have the template? Can you send me a download link?
