I am new to Promtail. I want to filter log lines with labeling using regex.
These are my log lines:
[DEBUG]: Starting the application
[PROCESS]: Trying a division
[WARNING]: dividing by zero(0) might cause an error
[ERROR]: Caught an exception: division by zero
[STATS]: 1 division has been tried in this run
This is my Promtail config:
server:
http_listen_port: 9080
grpc_listen_port: 0
positions:
filename: /tmp/positions.yaml
clients:
- url: "http://loki:3100/loki/api/v1/push"
scrape_configs:
- job_name: logscraping
static_configs:
- targets:
- localhost
labels:
job: logscraping
__path__: /var/log/*.log
test_label: test
pipeline_stages:
- regex:
expression: '^\[(?P<severity>.*)].*$'
- labels:
severity:
I can see the labels values in Grafana as severity = DEBUG WARNING ERROR PROCESS STATS
but when I select any of them, nothing shows up. What config do I need to see the lines with their respective severity label?
