Cluster deployment

Agents can be deployed to a cluster, a cluster may contain a single server or multiple servers.

Please note that you need to set up your servers or/and clusters before you will be able to deploy your agents. Check Servers & Clusters for more information about servers and clusters, how to set them up, and differences between them.

Agents can be deployed to a cluster via the ACC Web Portal or the Sequentum Enterprise (Desktop). This article also covers how to view and manage cluster deployments.

This section covers details on the management of cluster deployments in the Agent Control Center web portal.

Run agent pop up screen

Environment - Allows users to choose an environment to run their agents, options are production (PROD), Development (DEV) and testing (QA).

WindowlessThis is used for running agents with or without headers. There are many websites that have better performance on windowless mode than windowed mode e.g. Flex applications. There are also few websites that have better performance on Windowed mode. ACC provides its users with a facility to run their jobs with windowed or windowless mode. By default, its value is "Windowless = true".

Job-  Allows a scrape to execute under one job. Multiple sessions can also be covered under the job. A job will only be in completed status once all the sessions/runs under it get completed. 

Session ID - Sessions allow you to run multiple instances of the same agent at the same time. To run an agent in a session, you must specify a session ID when you run the agent and the agent must also be configured to support sessions i.e in performance or multiple sessions. If you are trying to run your agent in 5 sessions then mention 1-5/5 in Session ID it will start 5 seasons 1/5, 2/5, 3/5, 4/5 and 5/5.

Log LevelThrough this level of the logging can be set, there are mainly three types of logging in this,

  1. Low
  2. Medium
  3. High

We can choose the logging level from this option.

Input Parameters – Customized input parameters that can be used in the agent as per the requirement of an agent (if required).

Change Cluster

To change the cluster of the deployed agent, select "Change Cluster" from the context menu of the deployments.

A cluster has one or more servers, so once the cluster is changed by deploying an agent to another cluster, it gets deployed to all the servers added in that cluster and hence, it will remove agent deployment from all the servers attached to the previous cluster.

Remove From Cluster

To remove the deployed agent from a cluster, select "Remove From Cluster" from the context menu of the deployments. A cluster can have one or more servers, so once an agent is deployed to a cluster, it gets deployed to all the servers added in that cluster and hence when you use the Remove From Cluster option, it will remove the deployed agent from all the servers attached to a cluster.

Note: Removing the agent from a cluster does not remove the Job schedules or Job History or Run History if the agent was already run on a cluster from which the agent is removed. Also, this option is displayed only when the agent is already deployed to a cluster.
