Hi,

How do I store the value from the trigger condition so I can use it in the action section. For example  
My trigger condition:

ctx.results[0].hits.total.value/100 \> 0

Action Message:

Monitor {{ctx.monitor.name}} just entered alert status. Please investigate the issue.

- Trigger: {{ctx.trigger.name}}
- Severity: {{ctx.trigger.severity}}
- Count: {{ctx.results.0.hits.total.value}}
- Count Ratio: {{ctx.results.0.hits.total.value/100}}

Preview:  
Monitor test just entered alert status. Please investigate the issue.

- Trigger: test
- Severity: 1
- Count: 982
- Count Ratio:

I would like to get the value of “ctx.results.0.hits.total.value/100” in the message.

Hi @sushmamagesh,

Unfortunately, arithmetic operations cannot be done within the mustache template as far as I’m aware.

If you were dealing with the per-document fields, one workaround could have been to use script fields and perform the operation through that so you could have access to it in the `ctx` when defining the Action message. However, I don’t think `hits.total.value` is available there since it’s a value outside of the document.
