| dougsz | witek: Did you ever look at Gnocchi instead of InfluxDB, you had performance concerns right? | 16:02 |
| dougsz | (or anyone else) | 16:04 |
| witek | we have talked with Julien over a year ago and considered as an option | 16:04 |
| witek | but the work with Cassandra was already quite far and we decided for Cassandra | 16:05 |
| dougsz | ok, thanks | 16:05 |
| witek | I haven't measured performance with Gnocchi | 16:05 |
| dougsz | that was my next question :) | 16:06 |
| witek | there are some benchmarks available, mainly from Red Hat | 16:06 |
| witek | or only from Red Hat? | 16:06 |
| witek | the Red Hat guy in the presentation in Berlin said they had performance problems with Gnocchi at high sampling rates | 16:07 |
| dougsz | Yeah, I recall you picked up on that. | 16:08 |
| sc | what is high for him? | 16:08 |
| dougsz | Yeah - that's a good question sc, I need to go back and watch the video. | 16:08 |
| witek | Gnocchi calculates metadata when it receives the measurements and the CPU load gets high, from what he reported | 16:08 |
| witek | sc: typical sampling rates for Ceilometer/Gnocchi are 10 min. | 16:09 |
| witek | sc: that's the presentation I referred to: https://www.openstack.org/assets/presentation-media/OpenStack-Summit-2018-Prometheus-Operator-to-monitor-OpenStack.pdf | 16:10 |
| sc | witek: that what I remember (sorry guys but I have to refresh lots of things after leaving 11 months in an AWS jail) | 16:10 |
| witek | they wanted to address 0.1s sampling rate | 16:11 |
| dougsz | I guess that means something of the order of 10,000 metrics per second. | 16:14 |
| dougsz | Ah, 1 million metrics / second across the cluster, thanks for the link. | 16:16 |
| witek | yes, proud number | 16:19 |
| witek | wondering what storage backend for Prometheus they use | 16:21 |
| dougsz | Indeed | 16:23 |

| dougsz | bye | 16:26 |
