We have too fine buckets granularity for lower latencies, at cost of the higher
latecies (7+ minutes). This is causing spikes in SLI calculated based on that
metrics.
I don't have strong opinion about actual values - those seemed to be better
matching our need. But let's have discussion about them.
Values:
0.015 s
0.030 s
0.060 s
0.120 s
0.240 s
0.480 s
0.960 s
1.920 s
3.840 s
7.680 s
15.360 s
30.720 s
61.440 s
122.880 s
245.760 s
491.520 s
983.040 s
1966.080 s
3932.160 s
7864.320 s
This adds some useful metrics around pending changes and last successful
sync time.
The goal is for administrators to be able to alert on proxies that, for
whatever reason, are quite stale.
