Monitoring Cluster Activity
You can use Apple Qadministrator to find out what is happening within a cluster by
examining details (such as CPU usage, which batch is being processed, disk space
usage, and data activity) about each node in the cluster.
To monitor cluster activity in Apple Qadministrator:
1 In the Cluster list, select the cluster you want to examine.
2 Select a node in the cluster service nodes list.
3 Click the Info ( I ) button near the bottom of the Cluster list.
4 In the resulting window, click the CPU, Memory, Volume Info, or I/O Activity tabs to see
a variety of details about the selected node.
Accessing Activity Logs
Apple Qadministrator provides log information for a selected service or cluster. This
information is useful for troubleshooting distributed processing issues, and it can be
saved to a file and processed with XML tools and UNIX scripts.
To view or copy log information in Apple Qadministrator:
1 In Apple Qadministrator, select the service or cluster whose log you wish to view.
2 Click the Log button near the bottom of the Cluster list.
A new window appears displaying the log information for the selected service or
cluster. The log file is deleted when you close the window.
