I am trying to define various functions for each component level. However I am having multiple Splunk environments and I wanted to split Indexer group by different region. Say I have 2 Indexers in A region and 5 in B region and 1 in C region. Apart from splunk_server_group=dmc_group_indexers can I call custom group in my REST query to fetch particular indexers in that region? Or is that possible to call via custom macro? Please throw some light on this
