I am using Grfana for log monitoring and notification . When I tried on docker VM , gives me error and notification not sent here are log details

m/services/": dial tcp: lookup on read udp> i/o timeout"

@plawankar welcome to the :grafana: community!

It looks like there might be a configuration issue that’s keeping the alert from sending. You can double check that your webhook works independently of grafana by using the curl example in the slack documentation for webhooks from the command line of your VM to see if it can post.

@plawankar I edited your original post because it looked like your webhook was included in the error message - I redacted the portion of the error to remove it :smiley:
