Prometheus
Introduction
The OpenCensus Service can scrape your applications for stats, just like Prometheus traditionally does.
This makes the OpenCensus Service a drop-in replacement for Prometheus’ scrapers but with the added advantage that now your stats from all sorts of applications can be converted into OpenCensus Metrics and exported to diverse exporters.
Configuration
Following Prometheus’ configuration file guide at Prometheus Configuration
Instead of starting Prometheus with a configuration file, copy the contents of that configuration file.
Format
Paste and indent them under sub-section
receivers:
prometheus:
config:
<the_configuration_in_your_prometheus_config_file.yaml_goes_here>Example
So for an example YAML file comparing “After” and “Before”:
receivers:
prometheus:
config:
global:
scrape_interval: 15s
scrape_timeout: 8s
external_labels:
deployment: ml
api: v2
scrape_configs:
- job_name: 'jdbc_pool'
scrape_interval: 5s
static_configs:
- targets: ['localhost:8889']
- job_name: 'memcached'
scrape_interval: 8s
static_configs:
- targets: ['localhost:9977']global:
scrape_interval: 15s
scrape_timeout: 8s
external_labels:
deployment: ml
api: v2
scrape_configs:
- job_name: 'jdbc_pool'
scrape_interval: 5s
static_configs:
- targets: ['localhost:8889']
- job_name: 'memcached'
scrape_interval: 8s
static_configs:
- targets: ['localhost:9977']And then run the OpenCensus Service normally like you would
