Using the action policy Command
This example shows how to run a policy manually using the action policy command. The policy is registered
using the event none command under applet configuration mode, and then the policy is executed using the
action policy command in applet configuration mode.
event manager applet manual-policy
event none
action 1.0 syslog msg "Manual-policy triggered"
exit
!
event manager applet manual-policy-two
event none
action 1.0 policy manual-policy
end
!
event manager run manual-policy-two
Embedded Event Manager Watchdog System Monitor (Cisco IOS) Event Detector Configuration
Example
The following example shows how to configure three EEM applets to demonstrate how the Cisco IOS watchdog
system monitor (IOSWDSysMon) event detector works.
Watchdog System Monitor Sample1 Policy
The first policy triggers an applet when the average CPU usage for the process named IP Input is greater than
or equal to 1 percent for 10 seconds:
event manager applet IOSWD_Sample1
event ioswdsysmon sub1 cpu-proc taskname "IP Input" op ge val 1 period 10
action 1.0 syslog msg "IOSWD_Sample1 Policy Triggered"
Watchdog System Monitor Sample2 Policy
The second policy triggers an applet when the total amount of memory used by the process named Net Input
is greater than 100 kb:
event manager applet IOSWD_Sample2
event ioswdsysmon sub1 mem-proc taskname "Net Input" op gt val 100 is-percent false
action 1.0 syslog msg "IOSWD_Sample2 Policy Triggered"
Watchdog System Monitor Sample3 Policy
The third policy triggers an applet when the total amount of memory used by the process named IP RIB Update
has increased by more than 50 percent over the sample period of 60 seconds:
event manager applet IOSWD_Sample3
event ioswdsysmon sub1 mem-proc taskname "IP RIB Update" op gt val 50 is-percent true
period 60
action 1.0 syslog msg "IOSWD_Sample3 Policy Triggered"
The three policies are configured, and then repetitive large pings are made to the networking device from
several workstations, causing the networking device to register some usage. This will trigger policies 1 and
2, and the console will display the following messages:
00:42:23: %HA_EM-6-LOG: IOSWD_Sample1: IOSWD_Sample1 Policy Triggered
00:42:47: %HA_EM-6-LOG: IOSWD_Sample2: IOSWD_Sample2 Policy Triggered
