We just doubt it causes too much context switch. In our server, there is only statsd server and carbon-c-relay, but the `dstat` shows: ``` ----total-cpu-usage---- -dsk/total- -net/total- ---paging-- ---system-- usr...
If the regex matching result is cached, aggregator computing is lightweight, there only remains `+-*/`, so what's the load of thousands of `+-*/`?
Every rule starts a thread just seems scary. When the rules are many, then the communication and synchronization will become the bottleneck, because every metric has to be sent to...
Yes, derivative. Given two datapoints with (v1,t1), (v2, t2). It can be calculated as (v2 - v1) / (t2 - t1).
I think it's the graphite's `perSecond` function (http://graphite.readthedocs.org/en/latest/functions.html#graphite.render.functions.perSecond).
I think this feature is really more helpful than the fancy `hot reload`. Graphite has `derivative`, `nonnegativederivative`, and `perSecond`. And influxdb will not release 0.9 before it implements `derivative` and...
How about `calculate rate from metric.a.b.c into metric.a.b.c.rate interval 10s`, you wait for 10s, and you calculate some functions based on the data points received during the 10s. As to...
I think if the interval is 3s. Then the bucket will be [0, 3] , [3, 6] ... you put value in each bucket, and calculates each rate with the...
