Hello. I need information regarding CPU hardware requirements regarding influxdb. Currently I have the following setup:
1 - 1 Core
2- 25GB HDD
3 - 1GB Ram.
Running on cloud VPS server. Currently, I have set influxdb v 1.8.
Through MQTT I am sending 5 different values after 2sec with node-red and currently visualize data through Grafana. My point is when I started the system the RAM was 32% but after 4 days it increased to near 41%. Keeping in view that I have changed from “inmem” to tsi1. Also, HDD has increased by 5.46%. I also have set a retention policy of 4 weeks with shard group duration of 1 day. Is it normal? Cardinality is 1 on each measurement.
