I have configurations with opsgenie_key option and set all frequency related stuffs but still not able to receive email alerts.
Can anyone share complete config file for this setup
Elastalert provides a config rule example for Opsgenie here: https://github.com/Yelp/elastalert/blob/master/example_rules/example_opsgenie_frequency.yaml
If you're still not seeing alerts being created in Opsgenie, you can check the logs in your account to see if there are any errors relating to Elastalert.
Opsgenie support can also take a look at your account if you open up a ticket with us here: https://support.atlassian.com/opsgenie/
