Fastest method: The node ID is printed in the page footer — no admin access needed. Cross-reference it with cluster.properties to map the footer value → node.
Problem
When attempting to diagnose issues with Datacenter, often you'll want to specify which node the issue is occurring on since it may be specific to a certain instance. Typical Datacenter instances will be load balanced and so different users may experience different issues based on which node they connect to. This article helps determine which node an end user is accessing
Environment
Specific to JIRA Datacenter
Resolution
Scroll down to the bottom of the dashboard page
Check the footer and locate the text Atlassian JIRA Project Management Sofware (vX.X.X#XXXXX-XXXX:XXXXXXX:YOUR-NODE)
Cross reference the footer with your cluster.properties file located in your node local home
YOUR-NODE corresponds with the jira.node.id defined in the file
In the example, the node we'd be accessing would be node2.

Using the node ID
Once you've identified the node from the footer, you can locate the correct log file for that node. Each node writes to its own atlassian-jira.log in the node's local home directory:
<local-home>/log/atlassian-jira.log
This lets you target your log investigation to the specific node the affected user was connected to, rather than searching logs across all nodes.
