Hi,Ben,many thanks, I used "prometheus_tsdb_head_series" and
"prometheus_tsdb_head_chunks" to check my prometheus,and the results are as
follows.But I don't think I really understand what it means.For example,how
much memory does one serie or chunk take?Would you tell me how to
understand the r
Prometheus memory use depends on how much data you're feeding it.
Look at prometheus_tsdb_head_series
and rate(prometheus_tsdb_head_samples_appended_total[5m]).
I usually recommend planning to shard your Prometheus by namespace when the
head series is over 2 million.

Prometheus only uses what memory it needs. You can see this
with process_resident_memory_bytes and go_memstats_alloc_bytes. Cache
memory is not part of Prometheus, it is controlled by the kernel.

The picture below shows the memory that Prometheus used.As we can see,the
average memory is about 33G,and that's a lot of memory.Then I use the
command "free -h" to check the memory usage.The result is shown that the
most memory the prometheus used is cache.Would you tell me What is the
