ElastAlert is a simple framework for alerting on anomalies, spikes, or other patterns of interest from data in Elasticsearch.
ElastAlert works with all versions of Elasticsearch.
At Yelp, we use Elasticsearch, Logstash, and Kibana for managing our ever-increasing amount of data and logs. Kibana is great for visualizing and querying data, but we quickly realized that it needed a companion tool for alerting on inconsistencies in our data. Out of this need, ElastAlert was created.
If you have data being written into Elasticsearch in near real time and want to be alerted when that data matches certain patterns, ElastAlert is the tool for you. If you can see it in Kibana, ElastAlert can alert on it.
It works by combining Elasticsearch with two types of components, rule types and alerts. Elasticsearch is periodically queried and the data is passed to the rule type, which determines when a match is found. When a match occurs, it is given to one or more alerts, which take action based on the match.
Currently, we have built-in support for the following alert types:
Additional rule types and alerts can be easily imported or written.
In addition to this basic usage, there are many other features that make alerts more useful:
