Alarm	Description
Blocked Process Alarm	Blocked processes are processes that are waiting on information to become available in memory, or that are waiting for a shared resource, or for the completion of disk I/O or network I/O. A high level of blocked processes may indicate an under-configured machine.
Input Error Packets Flow Alarm	The Input Error flow represents the number of erroneous network packets coming into the machine per second. The Input Error Packets Flow alarm may warrant investigation as even a low error rate can indicate network problems.
Output Error Packets Flow Alarm	The Output Error flow represents the number of erroneous network packets sent by the machine per second. The Output Error Packets Flow alarm may warrant investigation as even a low error rate can indicate network problems.
Page In Alarm	A large number of page-ins may be a symptom of a large number of recent page-outs (see Page Out alarm below). To find out what process is reading these pages in, check the resident size of the processes you are running, and see which ones are increasing in size. Alternatively, a large number of page-ins may occur when a large process has just stopped, and the kernel decides to fill that space with memory pages owned by other processes. Check if an important process has ended unexpectedly.
Page Out Alarm	If an active process asks the kernel for more memory than there is immediately available, the kernel will write old memory pages out to swap space. This is known as paging. To stop paging, make sure that there is enough RAM available to support the size of the processes you want to run.
Percentage Busy Alarm (Most Active Disk)	The Most Active Disk gauge shows the disk with the highest read/write rates. The Percentage Busy alarm is triggered when the read/write rate of the most active disk exceeds a specified threshold. The type of alarm that is activated is determined by the percentage of read/write activity experienced by the disk.
Disk I/O wait time	The Disk I/O wait time alarm is triggered when one of the disks' I/O wait time exceeds a specified threshold.
Disk I/O service time	The Disk I/O Service Time alarm is triggered when one of the disks' I/O service time exceeds a specified threshold.
Swap Space Alarm	If the total amount of swap space allocated to a Unix host becomes full, the machine may halt all processes, or critical actions may be prevented from occurring. The Swap Space alarm may indicate a runaway process or an under-configured machine.
Swap In Flow Alarm	The Swap In flow represents the number of processes swapped from disk per second. The Swap In Flow alarm may indicate a machine that is under-configured for its workload.
Swap Out Flow Alarm	The Swap Out flow represents the number of processes swapped to disk per second. The Swap Out Flow alarm may indicate a machine that is under-configured for its workload.
Unix Status Alarm	Spotlight is re-establishing its connection to the Unix system.
Used Percentage Alarm	The Least Space / Disk Space container displays the percentage of used disk space for a specified filesystem. The Used Percentage alarm indicates that the specified filesystem is full or filling up. If the filesystem fills up completely, no more data can be written to it.
Zombie Processes Alarm	The Zombie button in the CPU panel shows the number of terminated child processes that have not been acknowledged by their parent process. The Zombie Processes alarm may indicate the presence of an inferior program, or an entry in /etc/inittab (or equivalent) that prevents init from completing its startup sequence.

Spotlight on Unix Drilldowns

Once a problem is isolated you can display a drilldown page with charts and tables that provide a detailed breakdown of the underlying statistics.

Drilldown	Keyboard Shortcut	Drilldown Pages	Description
Processes and Services	CTRL+P	Processes Page \| Zombies Page \| Services Page	The Processes and Services drilldown lists all the processes running on the Unix machine (including "zombie" processes), and all the services found in the /etc/services file (running or not).
Activity Summary	CTRL+A	Activity Page \| Disk Page \| Memory Page \| CPU Page \| Network Page \| Logins Page	Use the Activity Summary drilldown to show details of the activity on the Unix system.
Filesystems	CTRL+S	Filesystems And Disk Information	Use the Filesystems drilldown to show disk usage for each filesystem on the Unix system, and the proportion of disk space used by each filesystem.
Alarm Log	CTRL+L	Alarm log \| Alarms by Time \| Spotlight Today	The Alarm Log drilldown displays information on the alarms associated with the Windows system, including the name of the component that issued the alarm, the date and time the alarm was logged, and the severity of the alarm. Note: The Alarm Log drilldown is common to all Spotlight applications. The alarms are specific to the current Spotlight connection. Spotlight on Unix Alarms
