action string through D Commands
action string compare
To compare two unequal strings when an Embedded Event Manager (EEM) applet is triggered, use the action string comparecommand in applet configuration mode. To disable this function, use the no form of this command.
action label string compare [nocase] [ length integer ] string1 string2
no action label string compare
Syntax Description
label
Unique identifier that can be any string value. Actions are sorted and run in ascending alphanumeric key sequence using the label as the sort key. If the string contains embedded blanks, enclose it in double quotation marks.
nocase
(Optional) Specifies case insensitive comparison.
length
(Optional) Limits the comparison to the first integer character.
integer
(Optional) Valid values for the length argument range from 1 to 4294967295.
string1
Sequence of characters.
string2
Sequence of characters.
Usage Guidelines
String comparisons are performed on a byte-by-byte basis from left to right. If the strings are of unequal length, the longer string is compared greater than the shorter string. The action string compare command forces a comparison between two unequal strings, which is followed by an integer comparison of the result of the string comparison.
When two equal strings are compared, the result is 0 and when one string sorts before the other, the result is -1. For all other comparisons the result is 1. If the strings being compared are converted to integers, the comparison is performed between the results using the strcmp command.
The table below shows the built-in variable in which the results of the action string compare command are stored.
Examples
The following example shows how to compare two unequal strings:
Router(config-applet)# event manager applet compare Router(config-applet)# event none Router(config-applet)# action 1 set str "this contains some $str" Router(config-applet)# action 2 string compare nocase length 3 “contains” “$str”action string equal
To verify whether or not two strings are equal when an Embedded Event Manager (EEM) applet is triggered, use the action string equalcommand in applet configuration mode. To disable this function, use the no form of this command.

To specify the action of reading the state of a tracked object when an Embedded Event Manager (EEM) applet is triggered, use the action track readcommand in applet configuration mode. To remove the action track read command from the configuration, use the no form of this command.
Syntax Description
label
Unique identifier that can be any string value. Actions are sorted and run in ascending alphanumeric key sequence using the label as the sort key. If the string contains embedded blanks, enclose it in double quotation marks.
object-number
Tracked object number in the range from 1 to 500, inclusive. The number is defined using the track stub command.
Usage Guidelines
This command generates the following result variable:
- _track_state--State of the specified tracked object. The text string returned is either up or down. If the state is up, it means that the object exists and is in an up state. If the state is down, it means that the object either does not exist or is in a down state.
This command is used to help track objects using EEM. Each tracked object is identified by a unique number that is specified on the tracking command-line interface (CLI). Client processes such as EEM use this number to track a specific object. The tracking process periodically polls the tracked objects and notes any change of value. The changes in the tracked object are communicated to interested client processes, either immediately or after a specified delay. The object values are reported as either up or down. The enhanced object tracking event detector publishes an EEM event when the tracked object changes.
Examples
The following example shows how to specify event criteria based on a tracked object:
event manager applet track-ten event track 10 state any action 1.0 track set 10 state up action 2.0 track read 10Related Commands

The following example shows how to use the attribute command to specify a complex events for an EEM applet. In this example, the applet is run when the show bgp all command and any syslog message that contains the string “COUNT” occurs within a period of 60 seconds.
Router(config)# event manager applet delay_50 Router(config-applet)# event tag 1.0 cli pattern "show bgp all" sync yes occurs 32 period 60 maxrun 60 Router(config-applet)# event tag 2.0 syslog pattern "COUNT" Router(config-applet)# trigger occurs 1 delay 50 Router(config-applet-trigger)# correlate event 1.0 or event 2.0 Router(config-applet-trigger)# attribute tag 1.0 occurs 1 Router(config-applet-trigger)# attribute tag 2.0 occurs 1 Router(config-applet-trigger)# action 1.0 cli command "show memory" Router(config-applet)# action 2.0 cli command "enable" Router(config-applet)# action 3.0 cli command "config terminal" Router(config-applet)# action 4.0 cli command " ip route 192.0.2.0 255.255.255.224 192.0.2.12" Router(config-applet)# action 91.0 cli command "exit" Router(config-applet)# action 99.0 cli command "show ip route | incl 192.0.2.5"description (EEM)
To describe what an Embedded Event Manager (EEM) applet does, use the description (EEM) command in applet configuration mode. To remove the description of an applet, use the no form of this command.
Usage Guidelines
Use this command to describe what an EEM applet does. It is valid to have applets without a description. The Description of an applet can be added in any order, before or after any other applet configuration. Configuring a new description for an applet that already has a description, overwrites the current description.
Examples
The following example shows how to add or modify the description for an EEM:
Router(config)# event manager applet one Router(config-applet)# description "This applet looks for the word count in syslog messages" Router(config-applet)# event syslog pattern "count" Router(config-applet)# action 1 syslog msg hi
