Need to display temperature in Celsius

[clemente]

Hello all, this is my first post and I've searched a lot before posting this.
I have an APC InROw ACSC100 that must be monitored. I've put it in my map and used an item in the label showing the temperature. That is almost perfect. The only problem is that I need it in ° Celsius and not in °F. The conversion is done with the formula: (°C)= (°F)-32*0.555
Well, as you can see, I have everything needed to calculate it, but, for some reason, Zabbix doesn´t accept the terms. I was thinking about creating a new calculated item, but it didn´t work either.
I know it looks stupid, but I´m stuck! Can someone, please, help me. It´s very important. Thanks

how do you get the data??
SNMP??
maybe you can use an other OID.. or you can change it int the APC-config.

Hello Colttt. Thanks for the reply.
What I use for getting data is SNMP. For this particular data I use OID .1.3.6.1.4.1.318.1.1.13.3.4.1.2.6.0
I've read the documentation for this APC and could not find anything useful to convert or even display the data in Celsius. The only thing usefull is that I can display the temperature in Celsius ONLY in the browser interface, but it doesn´t help for the Zabbix thing. Any help will be welcome. Thanks.

Can you post what you tried to use for your formula in the calculated item your tried? A calculated item should work fine.

Sure. It's pretty obvious and, of course, it's wrong, as you can see:

{{RackInTemp.InRow}-32}*0.555

I have no experience with Zabbix. I just took the original formula to convert °C into °F, which is exactly:

°C=(°F-32)*0.555


Thanks.

It didn't work because you didn't use the right syntax . You can read up on calculated items in the manual (https://www.zabbix.com/documentation...pes/calculated).

Here's what the formula should probably look like:

(last("RackInTemp.InRow")-32)*0.555

Great, my friend! Now it's working! I can't believe.
I've been trying to put it to work for days and finaly it's alive.
I can't express my hapiness now. Thanks to everyone.
Case closed.

ok,

you search for tempUS

please try this OID:
.1.3.6.1.4.1.318.1.1.13.3.4.1.2.6.0

or do this:
snmpwalk -v2c -c public APC_IP .1.3.6.1.4.1.318.1.

you will see a lot of data there will be the temperature, too

Thanks, Colttt. But this is the same OID that I already use and it returns the °F temperature. The calculated item worked very fine.

dooohhhh.. sorry sometimes my copy&paste is not perfect..
try this:
.1.3.6.1.4.1.318.1.1.1.2.2.2.0

Oh, man! It just says "not supported". I think it's my model. It doens't support many of the OIDs I've tested.
But the solution with calculated item is just perfect.

[Colttt]

ok, but this a workaround..
can you please post the output from this command:

snmpwalk -v2c -c public APC_IP 1.3.6.1.4.1.318.1.
