I want to get memory available from two oids and add those memories and compare it with a threshold to give an alert. Is there a way where i can do this.

What type of system is it, we may have a plugin that already does what you're looking for.
If there isn't an already made plugin you would need to write your own to perform the queries and calculations.

Let us know if you have any questions.
Thank you

It is a Linux system and I am using UCD-SNMP-MIB to get 2 memory statuses in kb and add them and compare against a threshold

Can you share the OIDs you are referencing? I wrote a plugin that calculates disk space for a given mount using the UCD-SNMP-MIB table which might satisfy your use case:

These are the Oids that i need the status from.
UCD-SNMP-MIB::memAvailReal.0 =.1.3.6.1.4.1.2021.4.6.0
UCD-SNMP-MIB::memCached.0 = .1.3.6.1.4.1.2021.4.15.0

This plugin appears to leverage those OIDs:

You might give that a shot. With the understanding that this is not a plugin officially maintained by Nagios, feel free to share any issues you encounter with the plugin.
