Kapacitor alert formatting

I have using Kapacitor to raise alerts, which I want to send using post handler.
Following is the format of alert I am getting:


Issue here is I am getting “columns” array, and I want to template such that I only get _value inside columns and similarily inside values only value should be there. I tried using alert template but no progress.

Hello @Pratik_Das_Baghel,
I’m sorry I’m not sure this exceeds my kapacitor knowledge.
Maybe @Emrys_Landivar can help you?
Otherwise I’m afraid I can’t provide much help. I’m stumped. But if you ever decide to use Flux tasks, let me know! I can help with that.
