Using '/api/stats" endpoint for heath checking in WO mode

[Fábio Uechi]

Hi, 

I'm running OpenTSDB 2.3.0 instances on Kubernetes (Google Container Engine)  and Bigtable.

I was using the "/api/stats" endpoint for health checking (liveness and readiness probes) as suggested in the docs.

However when I switch to WO mode containers cannot start. The endpoint seems to be unreacheable.

Is that an expected behavior ? If so, do you recommend a different endpoint for this purpose ?

Thanks in advance

Just found the answer here: https://github.com/OpenTSDB/opentsdb/blob/master/src/tsd/RpcManager.java#L252

In WO mode only "/api/put" (telnet and http) is enabled.

Any ideas on how could I use it for health checking ? 

Maybe sending the same data point for a "healthcheck" metric over and over?

Hmm, we should definitely allow the other endpoints in WO mode. Mind filing a Github issue for this please and I'll patch it in 2.3.1? Thanks!
