LSASS Process
The Local Security Authority Subsystem Service (LSASS) process of the Windows operating system
processes authentication requests and permits/denies user requests. It processes domain logins from
users in AD. The LSASS Process area layout is shown in
Figure 396 .

LSASS Process area fields:
• CPU usage ratio trend graph—Shows changes of the CPU usage ratio used by the LSASS process
over the last 1 hour in a line chart. Point to a spot on the curve to view the CPU usage ratio at the
specific time point. To change the report period, click the Last 1 Hour icon
on the upper right of
the graph, and then select an icon from the list. Available options include Last 6 Hours , Today
, Yesterday , This Week , This Month , and This Year .
• Attribute/Value—Monitor index name and data.
{
CPU Usage in LSASS Process—CPU usage ratio of the LSASS process in the last APM polling
period.
{
Handles—Total number of handles opened by the LSASS process in the last APM polling
period.
{
IO Read Rate—Rate at which the LSASS process is reading data from I/O operations in the last
APM polling period. The I/O activity includes network, file, and device I/Os.
{
IO Write Rate—Rate at which the LSASS process is writing data to I/O operations in the last
APM polling period. The I/O activity includes network, file, and device I/Os.
{
Set Threshold—Click the Set Threshold icon to set alarm thresholds for the CPU usage ratio
of the LSASS process. The specified alarm thresholds appear on the CPU usage ratio trend
graph as dotted lines. The data is highlighted in orange when the CPU usage ratio reaches the
level-1 threshold, and is highlighted in red when the CPU usage ratio reaches the level-2
threshold. Use either the global thresholds or custom thresholds. For information about setting
the thresholds, see " 6 Configuration management ."
{
History Record—Click the History Record icon to view the history graph of the CPU usage
ratio trend. Point to a spot on the curve to view the CPU usage ratio at the specific time point.
