I am trying to understand fields in
status json for monitoring purposes. There are a few fields that I could not understand, and it would be great if someone can help out with these:
cluster->machines->id->memory->committed_bytes=> What does this field convey? And what operating system counter/metric is it using to get its value?
cluster->processes->id->memory->used_bytes=> What does this field convey? And what operating system counter/metric is it using to get its value (RES memory or something else)?
cluster->workload->keys->read=> What is this field for and how is it different from
cluster->workload->bytes->read/write=> what are these fields for? Are they indicating data exchange rate (read and written) at the interface of fdbserver, or does it indicate data written out by fdbservers to disk? How is the field useful for monitoring?
Is there any field that tells me per process or per machine disk read and write rate in bytes? I
