Today, data networks are ever increasing in size and complexity. For example, a datacenter may comprise hundreds of thousands of service endpoints configured to perform work. To reduce network wide degradation, a load balancer may send work requests to healthy service endpoints, as opposed to unhealthy and/or inoperative service endpoints. Accordingly, among other things, one or more systems and/or techniques for monitoring service endpoints, which may be scalable for large scale networks, are provided. In particular, a consistent hash function may be performed to generate a monitoring scheme comprising assignments of service endpoints to monitoring groups. In this way, multiple monitoring components may monitor a subset of endpoints to ascertain health status. Additionally, the monitoring components may communicate between one another so that a monitoring component may know heath statuses of service endpoints both assigned and not assigned to the monitoring component.
