is it possible to configure Prometheus to use text file as the source of metrics?
i tried config prometheus.yml like below but that not works.
scrape_configs:
- job_name: 'custom_job'
static_configs:
- targets: ['C:\CustomJobLogs\metrics.txt']
does Prometheus support metrics from text file or not?
if you use windows, use textfile collector from wmi_exporter
and if you use linux, use textfile collector from node_exporter
Actually this seems not possible:
static_configs:
-targets: ['C:\CustomJobLogs\metrics.txt']
But, it can be dobe by exposing metrics.txt to http and add the targets to that host:port
prometheus.yaml can be configured:
global:
scrape_interval: 10s
scrape_configs:
- job_name: example
metrics_path: /metrics
static_configs:
- targets:
- localhost:5000
Example for exposing the metrics.txt to http using flask(wsgi or any other can also be used):
from flask import Flask
app = Flask(__name__)
@app.route("/metrics", methods=['GET'])
def getfile():
with open("metrics.txt", "r+") as f:
data = f.read()
return data
if __name__ == '__main__':
app.run(host='localhost')
