I want to maintain log manager, especially for the custom logs. I tried to integrate graylog server but available supporting crate for graylog does not have support for non-std so I am facing issue. So can anyone suggest how can I maintain my substrate node logs. Is it possible with telemetry to send custom logs from both runtime-context and ocw-context

for your commit QA:
Loki + promtail + Grafana logging system may meet your needs.
