Hi everyone,
I have got an influxDB version 1.8 running on AWS EC2, and I would like to monitor it using the metrics from the internal database (that I query using Grafana).
For example I want to monitor the cache memory so the field memBytes of the measurement tsm1_cache. When I query it I get multiple values for the same time that correspond to several paths I believe.
The query: SELECT memBytes, path FROM _internal.monitor.tsm1_cache WHERE $timeFilter LIMIT 20
The result:

What am I supposed to do with that? I just want a metric that gives the total memory used by the database cache.
Thanks in advance,
