Promfetcher-release

This is the bosh release for deploying promfetcher alongside cloud foundry.

promfetcher was made for cloud foundry and the idea behind is to give ability to fetch metrics from all app instances in a cloud foundry environment.

User can retrieve is metrics by simply call /v1/apps/[org_name]/[space_name]/[app_name]/metrics which will merge all metrics from instances and add labels:

  • organization_id
  • space_id
  • app_id
  • organization_name
  • space_name
  • app_name
  • index - app instance index
  • instance_id - the same as index
  • instance - real container address

It also a service broker for cloud foundry to be able to set metrics endpoint for a particular which not use /metrics by default.

Example

Metrics from app instance 0:

go_memstats_mspan_sys_bytes{} 65536

Metrics from app instance 1:

go_memstats_mspan_sys_bytes{} 5600

become:

go_memstats_mspan_sys_bytes{organization_id="7d66c7e7-196a-40e5-a259-f5afaf6a56f4",space_id="2ac205af-e18f-49a9-9a8b-48ef2bab2292",app_id="621617db-9dd9-4211-8848-b245f3ea16b2",organization_name="system",space_name="tools",app_name="app",index="0",instance_id="0",instance="172.76.112.90:61038"} 65536
go_memstats_mspan_sys_bytes{organization_id="7d66c7e7-196a-40e5-a259-f5afaf6a56f4",space_id="2ac205af-e18f-49a9-9a8b-48ef2bab2292",app_id="621617db-9dd9-4211-8848-b245f3ea16b2",organization_name="system",space_name="tools",app_name="app",index="1",instance_id="1",instance="172.76.112.91:61010"} 65536
