does else exist on datadog is_match

Question

I am trying to set up slack monitors with datadog, based on the environment. For e.g. if the environment is production got to slack channel A and if it is uat go to slack channel B and all other environments should go to slack channel C.

 message = <<EOF
{{#is_match "environment.name" "production"}}
   {{#is_alert}} @slack-datadog-production {{/is_alert}}
{{/is_match}}
{{#is_match "environment.name" "uat"}}
   {{#is_alert}} @slack-datadog-uat {{/is_alert}}
{{/is_match}}
else
  {{#is_alert}} @slack-datadog {{/is_alert}}
EOF

But I can't find a way to do the last part where all others should go to slack channel B. Looked at the documentation in https://docs.datadoghq.com/monitors/notifications and googled but couldn't find anything that can do an else condition.

Answer 1

Starts to get messy, but you could nest two "does not" conditional variables, like this:

 message = <<EOF
{{#is_match "environment.name" "production"}}
   {{#is_alert}} @slack-datadog-production {{/is_alert}}
{{/is_match}}
{{#is_match "environment.name" "uat"}}
   {{#is_alert}} @slack-datadog-uat {{/is_alert}}
{{/is_match}}

{{^is_match "environment.name" "production"}}
   {{^is_match "environment.name" "uat"}}
      {{#is_alert}} @slack-datadog {{/is_alert}}
   {{/is_match}}
{{/is_match}}
EOF

Answer 2

You can actually just use:

EOF
@slack-datadog-{{environment.name}}
EOF

Datadog's monitor templating feature will fill in the blank and forward to the relevant channel as long as you whitelisted it in the integrations tile for Slack.
