Thank you for answering my questions, you're really helping me out!
I'm sorry for beeing vague for both 2nd and 3rd questions. I'll
explain more about my project and say what I want to collect and analyze.
(I use "player" as an "user")
* Player count, location, their transactions(buying something from
store)
* Sever performance, general performance such as CPU, RAM etc.
* Database performance, such as MySQL, Redis, RabbitMQ and MongoDB.
* Systems performance, such as loaded player data, packets across
the network, physical server usage.
* Game specific metrics, such as in-game curreny earned/spent, game
length, game actions(player join X game etc.) and more.
Some yes and some no.
From your list the server performance, packet counts, database metrics
are all core things you'd use Prometheus for. Many pieces of software
already support Prometheus directly or have exporters available to make
scraping metrics very easy.
For you other two bullet points it really depends on what you are
thinking. If you are looking for high level metrics (such as total
numbers of users by country, total amount of currency spend, total game
lengths, etc.) where you are producing data with relatively low
cardinality dimensions (labels) then again yes this would be suitable
for Prometheus.
However, if you are looking for per-user data, or the use of other high
cardinality dimensions (such as IP address) then Prometheus wouldn't be
suitable. Equally if you are wanting to store event data (e.g.
transaction details about a store purchase) Prometheus wouldn't be
suitable. For these you would generally use an event store/database
(either relational or noSQL). You can still generate metrics from that
data, so Prometheus could still have a place in the overall system, but
as Ben says it is really about monitoring the overall state of the
system, with alerts or dashboards showing number of online users,
amounts of sales, CPU usage, database connections or network bandwidth.
