DescriptionEmbedded Event Manager Event
Occurs when the used memory for a specified
processor complex has either increased or decreased
by a specified value.

Watchdog System Monitor (WDSysMon) Event Detector for Cisco IOS XR Software Modularity
The Cisco IOS XR Software Software Modularity Watchdog System Monitor Event Detector detects infinite
loops, deadlocks, and memory leaks in Cisco IOS XR Software Modularity processes.
Distributed Event Detectors
Cisco IOS XR Software components that interface to EEM event detectors and that have substantially
independent implementations running on a distributed hardware card should have a distributed EEM event
detector. The distributed event detector permits scheduling of EEM events for local processes without requiring
that the local hardware card to the EEM communication channel be active.
These event detectors run on a Cisco IOS XR Software line card:
•
System Manager Fault Detector
•
Wdsysmon Fault Detector
•
Counter Event Detector
•
OIR Event Detector
•
Statistic Event Detector
Embedded Event Manager Event Scheduling and Notification
When an EEM handler is scheduled, it runs under the context of the process that creates the event request (or
for EEM scripts under the Tcl shell process context). For events that occur for a process running an EEM
handler, event scheduling is blocked until the handler exits. The defined default action (if any) is performed
instead.
The EEM Server maintains queues containing event scheduling and notification items across client process
restarts, if requested.
Reliability Statistics
Reliability metric data for the entire processor complex is maintained by the EEM. The data is periodically
written to checkpoint.
Hardware Card Reliability Metric Data
Reliability metric data is kept for each hardware card in a processor complex. Data is recorded in a table
indexed by disk ID.
