The HA Cluster Management page details the current status of any nodes running in high availability mode and is used to perform quiesce actions for a node.
Operators with the following roles can access this page:
You can access this page from Dev Studio by clicking.
The following data is displayed on this page for each node.
|Node||The name of the node|
|NodeID||The node ID|
|Runstate|| The status of the node: |
|Active Users||The number of active users|
|Last Pulse||The date and time of the last system pulse|
|Last Started||The date and time that the node was last started|
To perform an action on any of the nodes listed on this page, select the check box next to the node(s) and then click one of the following buttons:
- Quiesce – Begin the quiesce process for the selected node(s).
Note: When using the slow drain method for quiesce, you must take the node(s) out of the load balancer rotation before performing this action.
- Cancel Quiesce – Cancel the quiesce process for the selected node(s).
- Refresh Data – Refresh the node data listed on the page.
- Managing the cluster using the Pega API
You can use the Pega API to integrate Pega Platform high availability into a Network Operations Center (NOC). The Pega API provides RESTAPIs for managing quiesce and other operations.
- Quiescing high availability nodes
Quiesce is a process for cleanly taking a Pega Platform node out of service for maintenance or other activities.
