Diagnostics page

Administrators can use the system diagnostics page to look for root causes of platform performance issues.

This page provides an overview of useful diagnostic information about a running instance and cluster nodes.

Navigate to System Diagnostics > Diagnostics Page.
Figure 1. Diagnostics


To see how much memory each node is using, you can use the 'stats' page for each node in System Diagnostics. Each 'stats' page lists the available and in-use memory. Bear in mind that memory use will fluctuate, and it's not uncommon for it to 'creep' up to beyond 95% usage before memory garbage collection reduces it back to normal levels.

Cluster Nodes

If you're running a multiple-node cluster, it's useful to know the status of each of the nodes. The nodes check in every 30 seconds and display their current status in the 'sys_cluster_state' table. You can see this information by clicking the 'Note States' module in the 'System Cluster' application.


If you're looking for 'what was this user doing at this time', the transaction log is your friend. The transaction log lists all transactions, the user who performed it, and the URL the user was going to. You can get to the transaction log by going to System Logs > Transaction Log.


The email log can help you determine whether emails are sending, who they're sending to, and the format of the message itself. The email log also shows all inbound email. You can get to the email log by going to System Logs > Email Log.

Configuring System Diagnostics Properties

Use properties to define when things appear red on the page.
