Hi,

Sometimes, when all the nodes are not available in the cluster, you'll see the descrepancies. From the Admin Studio, You'll see the status of them as a group but even when one node is out of the cluster it'll be visible when you click on the option of Number of Nodes Running from Admin Studio.

In Such cases, The report Definiton you created for status is accurate. But it's advisable to report the status mismatch to your Pega Admin when occurs. Also, Similar Problem occurs when you are using Pega in Containerization enviornment even.

Your admin should observe the logs and proceed for Nodes restart if required.

If Possible, Please share me the information used to pull the status created in Report Definition. I'll add couple of screenshots for your reference.
