Autodiscovery rule help

[rcarvalloh]

Hello,

I have the following scenario:

I have an OLT, I need to monitor its ONT clients, I created an item that walks the following OID:

 1.3.6.1.4.1.3902.1012.3.28.1.1.2

This returns several OIDs in the form of:

 1.3.6.1.4.1.3902.1012.3.28.1.1.2.ONT_CHASSIS_LOCATION.ONT_PORT (ie. 1.3.6.1.4.1.3902.1012.3.28.1.1.2.268502016.42)

This specific OID returns the name of each ONT configured in the device (can be hundreds), but encoded in the OID itself there are other values I need, specifically ONT_CHASSIS_LOCATION and ONT_PORT, the walk item stores both items as SNMPINDEX (ie. 268502016.42)

I need to:

• Split #SNMPINDEX into 2 additional variables #ONT_CHASSIS_LOCATION and #ONT_PORT
• I need to do simple binary operations on ONT_CHASSIS_LOCATION to convert this numeric value into a meaningful value, ie: 268502016 should be stored as 1/1/5 instead of the number
• Have ONT_PORT, ONT_CHASSIS_LOCATION, SNMPINDEX, and SNMPVALUE available for the discovery rules (so I can make prototypes to monitor several things per ONT)

The problem is that I am 100% clueless as to how to achieve this. I tried preprocessing with a regex in the item and also in the discovery rule, but it only returns the first occurrence. Then I am not sure how to store those values in the variables I mentioned, for the binary operations and I will use Javascript, I don't know how to tackle this problem.

Any help is appreciated.
