Hey,

this forum is about watcher (a plugin written and maintained by elastic) and not elastalert, which is not affiliated with elastic. You might have more luck checking out, if there is dedicated forum for elastalert (not on [http://discuss.elastic.co](http://discuss.elastic.co)) or ask questions on the [Ecosystem Discuss Group](https://discuss.elastic.co/c/ecosystem).
