2.Paid products like Datadog - Most of the vendors charge on a per-host basis. What's the underlying logic for charging like that?
If I were to use a vendor for this, I would like to be charged according to the number of spans sent for storage like in logs, say $2 per million spans or $0.2 per GB. Only Datadog seems to charge on such basis and asks for $1.7 per million of spans apart from $31 per host which covers 1M spans only. Does DataDog give you control of which spans to visualise & store?
- Does any vendor give you control of spans to process or a clear pricing estimate for the tracing part?
What other things should I look when using Jaeger or buying Datadog? My primary need is to monitor and debug my applications.
