Abstract: Some embodiments of the invention provide a method for collecting metric values relating to operations of a set of one or more resources executing on host computers in a datacenter. In some embodiments, the method hierarchically collects and analyzes samples, with a first set of samples collected and analyzed in the data plane, and a second set of samples collected and analyzed in the control plane by aggregating the samples collected in the data plane. In some embodiments, the data plane includes host computers on which sample collecting engines (e.g., service engines) execute, while the control plane includes a set of one or more servers that obtains sample data collected by the host computers, and aggregates and analyzes this data.

Abstract: Some embodiments provide a novel method for dynamically adjusting sampling rates of a middlebox service. In some embodiments, the method is performed by the controller. The method configures the forwarding element to collect samples from packets processed by the forwarding element at a first sampling rate. The method analyzes the samples in order to collect information regarding the packets processed by the forwarding element. Based on the analysis, the method detects a new traffic pattern in the packets processed by the forwarding element. The method then configures the forwarding element to collect samples from packets processed by the forwarding element at a second sampling rate different than the first sampling rate.

Abstract: A custom metrics technique includes: accessing a packet; processing the packet using a packet processing pipeline of a service engine in a distributed network service platform, including: reaching a pre-specified point in the packet processing pipeline; inserting, in the packet processing pipeline, script code that corresponds to the pre-specified point; executing the script code to collect at least metric-related data associated with a user-specified metric object; and executing remaining packet processing pipeline.
