I/O State
APM can monitor the I/O status of the disk drivers in the Mac OS, as shown in Figure 86.
Figure 86 I/O State area layout
I/O State area fields:
 Device Name—Name of the disk drivers in the Mac OS.
 I/O Rate—Size of the input/output data in the disk driver per second.
 Transfer/Sec—Number of the transfer times in the disk driver per second. A transfer is an I/O
request to the physical disk. Multiple logical requests can be integrated into a single I/O request to
the disk. The size of the transferred data in each transfer is not fixed.
OpenBSD
OpenBSD's performance and stability greatly affects the performance of applications running on it. APM
provides the ability to monitor OpenBSD 4.6 or later versions of the operating system.
Adding an OpenBSD application monitor
APM monitors OpenBSD operating systems through CLI. When you add application monitors for
OpenBSD, follow these guidelines:
 Enable Telnet or SSH on OpenBSD. For more information, see the OpenBSD configuration guide.
 Obtain the correct username and password of the Telnet or SSH user who has the OpenBSD
administrator's privileges
 To view traffic statistics in the monitor report of the OpenBSD application, make sure at least one
probe is configured in APM. After an OpenBSD application monitor is added, APM sends the IP
address of the monitored OpenBSD application to the probes for traffic collection.
To add an OpenBSD application monitor:
1. Click the Resource tab.
2. Enter the Add Application page in one of the following ways:
