Pega API for detecting node state
H Team,
Is there a Pega API service to detect the current node state? The below two services does quiesce and unquiesce operations. However, there seems to be no service that can tell the current system state (quiesced / running).. Is there any such (hidden) service?

The Nodes APIs provide the ability to start and cancel quiescence (immediate drain or slow drain) on any node in the cluster, list the current configuration settings for a node or the whole cluster, download the prconfig.xml file, and list the nodes that are in the cluster.

But the node state is not returned by the /api/v1/nodes service. Below is a sample response which just shows the nodes but no status.
{
"data": {
"result": [
{
"clusterMembers": [
{
"nodeID": "497cff1f2754276600466a7eec3b442e"
},
{
"nodeID": "c60f6e095eff21f568d9ed5d31a5fee3"
}
]
}
]
},
"servedBy": "c60f6e095eff21f568d9ed5d31a5fee3",
"status": 200
}

Hi Tarun,
In Pega v7.4 the API doesn't give much information and only gives the node id. Below API might be helpful for your use case:
http://localhost:8080/prweb/api/v1/nodes/{nodeIdentifier}/state.
Whereas if you go for Pega 8.x version it the API provides the below information along with the status:
{ "data":
{ "result":
[ { "cluster_members":
[ { "node_type": "WebUser,BackgroundProcessing,Search,Stream",
"running_state": "Running",

Hi Tarun,
Hope you are aware of pdc,You can use pdc to monitor nodes health,status etc.
Thanks,
