Deployment Support

This page describes the hardware components required for the Web Monitoring Private Synthetic Agent (PSA) and API Monitoring Private Synthetic Agent (PSA) to run in the Docker engine, Kubernetes cluster, and Minikube.

Web Monitoring PSA supports:

  • SaaS Controllers
  • On-premises Controller >=21.4.1 with on-premises Synthetic Server >=21.4.1 
  • Selenium 4.9.1
  • Chrome browser
  • x86-64 architecture

API Monitoring PSA supports:

  • SaaS Controllers >=21.11
  • Javascript
  • x86-64 architecture

Web Monitoring PSA on Google Cloud Platform is not supported with an on-premise Synthetic server

Number of Measurement Containers 

You can calculate the number of required concurrent containers using this formula:

( (Number of Jobs) x (Average job duration in minutes) / (Frequency in minutes))

For example, the number of containers required for 10 jobs with an average duration of 30 seconds per job executed at 5-minute interval needs:

(10 x (30/60) ) / 5 )  = 1 container

Concurrent Measurements

The Kubernetes cluster specifications determine the number of concurrent measurements that can be executed. Any submission of jobs beyond the infra limits leads to the queuing of jobs in the Kubernetes cluster. To scale the number of concurrent jobs automatically, enable cluster auto-scaler. K8S auto-scaler functionality depends on the cloud or the managed service provider.
