The array\_compare condition was added in Watcher 2.0. Which version are you running?

Hello,  
Thanks for prompt reply.

I think i'm running the old version i.e i found in plugins/watcher/elasticsearch-watcher-1.0.1.jar  
I will update this and will check if this works fine for me 😄

Thanks

Hi @skearns.

I'm creating a watcher that i want to check the route performance whether it has some positive\_sessions change or negative\_sessions change.

Also i want to ask whether watcher saves history and then calculates data from history + current?

I have created this watcher please let me know where am i doing wrong

And can i create single alert for both positive and negative sessions? or do i need to create seperate?

Sorry for bad english
