What Does This Do

log template only probe are rate limited to a higher rate. if condition is set and returns an error, we don't want to return a snapshot at the same rate just for reporting the condition evaluation failure. So we are introducing a specific sampler at 1/s rate to report error in that case.

@jpbempel
Add an error sampler for Log probes
3f98bc4 
log template only probe are rate limited to a higher rate. if condition
is set and returns an error, we don't want to return a snapshot
at the same rate just for reporting the condition evaluation failure.
So we are introducing a specific sampler at 1/s rate to report error
in that case.
@jpbempel jpbempel force-pushed the jpbempel/log-template-error-rate branch from 0678c9d to 3f98bc4 Compare February 19, 2026 21:05
