i want to access a substring from the _payload of the integration that it recieves for alerts

[Mohd Aamir Mir]

i have an alert for which i want to basically append the service name at the end of the title when it send notifications to jira(opsgenie)

sharing the complete payload at the end..

i want the value of "metric.labels.destination_service_name" to show dynamically in the description or title
eg.
metric.labels.destination_service_name = \\\"mp-customer-catalog-api\\\"\"

currently i am able to access the below string from _payload json  as

payload: resource.type = "k8s_pod" AND metric.type = "istio.io/service/client/request_count" AND metric.labels.destination_service_name = "mp-customer-catalog-api"

but since jira doesnt support regex directly in  the alert rules i am not able to extract the value of metric.labels.destination_service_name which is "mp-customer-catalog-api"

when i am setting
payload: {{_payload.incident.condition.conditionThreshold.filter}}
in the alert rule of integration (create alert)

this is the full payload

Hi @Mohd Aamir Mir Welcome to the Atlassian Community

Have you considered extracting the valuable information of the payload by means of smart value operations on texts provided by Atlassian? 

You can use indexOf(String str) to locate the key-value pair you're interested in.

Then use substring(int start, int end) or one of the other substring commands to get the value you're after.

Kind regards,
Dick
