#Huawei snmp get sfp transceiver atenuation uW convertion to dBm. Not working

[vdalcin]

Sorry for my english, I'm using google translator:

I need to collect via snmp attenuation modulo sfp switch huawei S6720-EI.
the oid is in the link below.
the problem is that the values are in uW.
so I can not convert directly to the zabbix item.
I have to get the value via script ...
the results are not very satisfactory. Sometimes a collection fails ..
in the end would have as zabbix already convert the value of the item adding this type of data to it?

as shown in 7.2.7.10 What Are the MIB OIDs of Optical Module Information?
of the link below:

http://support.huawei.com/enterprise/docinforeader!loadDocument1.action?contentId=DOC1000088764&partNo=10092

This object indicates the receive power of an optical module, in uW. uW = (10 ^ (dBM / 10)) * 1000.

We need the value in dBm.

It is suggested if there is no such conversion implements it

Thanks for any help:
