Arithmetic operators
Elastic Cloud Serverless projects are autoscaled environments, fully managed by Elastic and available on Elastic Cloud. Availability This functionality is generally available and ready for production usage. Serverless interfaces and procedures might differ from classic Elastic Stack deployments. The Elastic Stack includes Elastic's core products such as Elasticsearch, Kibana, Logstash, and Beats. Availability This functionality is generally available and ready for production usage. This functionality is in technical preview and is ready for evaluation. Use with caution in production; it is not recommended for mission-critical workloads. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features. Specific Support terms apply. Unless stated otherwise on the page, this functionality is available when your Elastic Stack is deployed on Elastic Cloud Hosted, Elastic Cloud Enterprise, Elastic Cloud on Kubernetes, and self-managed environments. This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes.

These binary operators perform arithmetic between scalars and instant vectors. For vector–vector operations, the metric name is dropped from the result.

Adds the two operands element-wise. For vector–vector operations, the metric name is dropped.
Operands
lhs,rhs(instant_vectororscalar)- The left and right operands. When one side is a scalar, the operator applies between the scalar and each sample of the vector.
Returns
An instant_vector, or a scalar when both operands are scalars.
Example
requests_total + requests_errors
Differences from Prometheus
Native histogram operands, such as h * 2, and some pairs of instant vectors, listed in Prometheus compatibility, aren't supported yet.

Divides the left operand by the right operand element-wise. For vector–vector operations, the metric name is dropped.

requests_errors / requests_total

Returns the remainder of dividing the left operand by the right operand element-wise. For vector–vector operations, the metric name is dropped.
Operands
lhs,rhs(instant_vectororscalar)- The left and right operands. When one side is a scalar, the operator applies between the scalar and each sample of the vector.
Returns
