This PR add Mongodb input plugin per collection stats gathering.

It will discover collection in each database.
You can specify the databases you want to gather collection stats by setting the col_stats_db option.

  ## When true, collect per collection stats
  # gather_col_stats = false
  ## List of db where collections stats are collected
  ## If empty, all db are concerned
  # col_stats_dbs = ["local"]

New metrics per collections are :
mongodb_col_stats

  • tags:
    • hostname
    • collection
    • db_name
  • fields:
    • size (integer)
    • avg_obj_size (integer)
    • storage_size (integer)
    • total_index_size (integer)
    • ok (integer)
    • count (integer)
    • type (tring)

Shouldn't fmt.Errorf be used here to return an error and prevent further execution?

I think maybe a continue so it continues adding other (likely valid) colls
