I changed the configuration like this
- INFLUXDB_DATA_INDEX_VERSION “inemem” to “tsi1”
- INFLUXDB_DATA_WAL_FSYNC_DELAY “0” to “10ms”
- influxdb:1.6.4 to influxdb:1.7.6
After changing these configurations, the disk usage increased too much for a while. It returned to its normal level after services crashed. The part I suspect is that the kapacitor imposes too much load on this disk. Which configuration do you think caused this and how did it affect it?
