Retroview

Retroview is the vendor's cloud monitoring. Once a minute Sapsan sends telemetry — the full counter catalog, including all the extended detail — and Retroview keeps it for months. Nothing needs to be configured on the server: the channel works together with the license.

When to go to Retroview instead of the built-in Prometheus server:

  • history and trends — traffic and stream count growth over months, capacity planning;
  • postmortems — what happened to the stream at night: telemetry survives restarts and does not depend on server memory;
  • usage reconciliation — the counters are sampled over time by an external system, so the bill can be verified even if the servers were restarted;
  • root-cause analysis without the extended counters option — telemetry always carries the causal detail;
  • curated alerts — product rules instead of homegrown ones.
