send2jsm trigger severity and host tags

[Kakollu_ Ashok]

Testing JIRA service management with Zabbix . Followed the steps as per the Integrate with Zabbix | Jira Service Management Cloud | Atlassian Support. I'm getting alerts created automatically, however it seems I can't send {TRIGGER.SEVERITY} and a custom host tag {EVENT.TAGS.ENVIRONMENT} in alert summary/subject and description.

Hi Kakollu,

Where are you trying to modify the Summary? Is it in the Create rule in the Integration?

Thank you for your response @John Funk . Here is my challenge. I'm not able to send HOST Tags such as Environment as an argument to JSM. On the JSM alert rule I created an alert property called "{{_payload.environment}}" and that property is dragged on to alert "message" field in alert rule . I'm now adding environment as a custom argument to send2jsm command. But for some reason, it is not working. Here is my full send2jsm command 

/home/jsm/jec/scripts/send2jsm -triggerName='{TRIGGER.NAME}' -triggerId='{TRIGGER.ID}' -triggerStatus='{TRIGGER.STATUS}' -triggerSeverity='{TRIGGER.SEVERITY}' -triggerDescription='{TRIGGER.DESCRIPTION}' -triggerUrl='{TRIGGER.URL}' -triggerValue='{TRIGGER.VALUE}' -triggerHostGroupName='{TRIGGER.HOSTGROUP.NAME}' -hostName='{HOST.NAME}' -ipAddress='{IPADDRESS}' -eventId='{EVENT.ID}' -date='{DATE}' -time='{TIME}' -itemKey='{ITEM.KEY}' -itemValue='{ITEM.VALUE}' -recoveryEventStatus='{EVENT.RECOVERY.STATUS}' environment '{HOST.TAGS.Env}'

Not sure what I'm missing here. Please note that Env is a custom tag created for Zabbix host. I tried with EVENT.TAGS as well ,but nothing worked.
