Hi @architkhanna, as me and @richgalloway said, you have two choises: to make a PoC to see you data e.g. from one server and make a calculation, to see the dimension of a single event, calculate dimension x number of events, adding a margin in both cases. At first glance, 10 kb seems a bit too much for a single event, as it means an average of 10,000 characters for each event (in your case 200 fields each one with 50 chars!), just as an example a Windows event (that is among the most verbose) is always less than 1kb and if we talk about Linux, we normally have less of 0.1 kb. Anyway, put e.g. 1000 events in a file and see its dimension. At the same time, check the number og events, because 150k events are the usual number of few windows servers or 2-3 Domain Controllers. Ciao. Giuseppe
