Send data to loki via AWS EventBridge, Azure EventGrid or simple webhooks

dbe121 · December 12, 2023, 5:44pm

Hi,

I have a service that can send log streams to AWS EventBridge, Azure EventGrid or as simple webhook. Is there any option to connect one of the services to loki to drop the logs?

BR and thanks in advance

Yes, e.g. AWS EventBridge → AWS Lambda → Loki. A few lines of Lambda code in your favorite language and it should be possible.

@jangaraj thanks for your answer
Would you use a post request to https://logs-prod-xxx.grafana.net/loki/api/v1/push endpoint or how would you send the logs from the lambda?

Yes, random python example from the internet:

github.com

sleleko/devops-kb/blob/master/python/push-to-loki.py

# example of usage grafana/loki api when you need push any log/message from your python scipt
import requests
import json
import datetime
import pytz

host = 'somehost'
curr_datetime = datetime.datetime.now(pytz.timezone('Asia/Yekaterinburg'))
curr_datetime = curr_datetime.isoformat('T')
msg = 'On server {host} detected error'.format(host=host)

# push msg log into grafana-loki
url = 'http://host-where-loki-run:3100/api/prom/push'
headers = {
    'Content-type': 'application/json'
}
payload = {
    'streams': [
        {
            'labels': '{source=\"Name-of-your-source\",job=\"name-of-your-job\", host=\"' + host + '\"}',

Of course real code for your use case depends on your input format. “sending logs to AWS EventBridge” is vague definition.
