The query language of Yandex Monitoring is used to configure dashboards and alerts. In the query string, you enter an expression written in the query language in tokenized or text mode. The query string allows you to apply functions to a set of metrics uploaded from a specific service. To display metrics from different services on a dashboard's chart, create multiple query strings.
