I'm using prometheus postgres_exporter <https://github.com/prometheus-community/postgres_exporter/> (v0.15.0) to monitor PostgreSQL database.
There are RAM-, CPU- and FDs-related metrics: # HELP process_cpu_seconds_total Total user and system CPU time spent in seconds. # TYPE process_cpu_seconds_total counter process_cpu_seconds_total 0.09 # HELP process_max_fds Maximum number of open file descriptors. # TYPE process_max_fds gauge process_max_fds 1.048576e+06 # HELP process_open_fds Number of open file descriptors. # TYPE process_open_fds gauge process_open_fds 11 # HELP process_resident_memory_bytes Resident memory size in bytes. # TYPE process_resident_memory_bytes gauge process_resident_memory_bytes 1.077248e+07 # HELP process_start_time_seconds Start time of the process since unix epoch in seconds. # TYPE process_start_time_seconds gauge process_start_time_seconds 1.69955861358e+09 # HELP process_virtual_memory_bytes Virtual memory size in bytes. # TYPE process_virtual_memory_bytes gauge process_virtual_memory_bytes 1.26656512e+09 # HELP process_virtual_memory_max_bytes Maximum amount of virtual memory available in bytes. # TYPE process_virtual_memory_max_bytes gauge process_virtual_memory_max_bytes 1.8446744073709552e+19 How to understand, does these metrics shows PostgreSQL (database) process resources consumption, or postgres_exporter (just an exporter itself) process resources consumption? I suspect that these are exporter resources, because RAM consumption is low (ones-to-tens of megabytes, versus hundreds of megabytes that would be typical for a database daemon). But this is just a wild guess. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
