We are using TA unix and Linux to get the data from UFs and wants this data to be converted into metrics data and to store it in custom metric index.
Is this feasible and how?
either you switch the way you're collecting it or convert the data with mcollect into metrics format. Look here for more information.
Whether it's feasible or not depends on how much data you are searching on and what your use case is right now.
@sharmarohit123 you should try to convert inputs.conf of existing *NIX TA and configure the same to write to metrics index instead.
