# Prometheus can scrape additional jobs via scrape_configs. The default automatically # includes all of the exporters supported by the omnibus config. # # See: https://prometheus.io/docs/operating/configuration/#<scrape_config> # # Example: # # prometheus['scrape_configs'] = [ # { # 'job_name': 'example', # 'static_configs' => [ # 'targets' => ['hostname:port'], # ], # }, # ] # ### Prometheus Memory Management # # Prometheus needs to be configured for how much memory is used. # * This sets the target heap size. # * This value accounts for approximately 2/3 of the memory used by the server. # * The recommended memory is 4kb per unique metrics time-series. # See: https://prometheus.io/docs/operating/storage/#memory-usage # # prometheus['target_heap_size'] = ( # # Use 25mb + 2% of total memory for Prometheus memory. # 26_214_400 + (node['memory']['total'].to_i * 1024 * 0.02 ) # ).to_i
