# 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
