Administrator Guide

Following snippet triggers a script even if any one of the pattern matches:

Dell(conf)#script trigger-event Server_Reporter_Event log-event tag tag-or-

ex "Major alarm" "Minor alarm"

Dell(conf)#script event-handler handler1

Dell(conf-screvt-handler)#execute Report_server.tcl args 4

Dell(conf-screvt-handler)#triggered-by Server_Reporter_Event

Dell(conf-screvt-handler)#no disable

Managing Executed Scripts

Use any of the following commands to manage or control the scripts; for example, stop, kill, resume,

unscheduled, and clear.

Protect system resources by scheduling scripts to run when resources are within the threshold

parameters you configured. System resources include the switch CPU, memory, and file system. For

example:

Dell#show script process detail

JobID Script Type Script Status Username Script Name Args

000 TRIGGER Running admin admin.pl

001 REPEAT Running user1 sample.zsh hello

002 CONF WATCH Watch Blocked user2 args.pl

003 EXEC Scheduled user2 args.pl hi

Dell#

The script status are determined as follows:

• Scheduled — The script is scheduled to run.

• Running — The script is currently running.

• Stopped — The script is suspended.

• Completed — The script run is successful and exits normally.

• Watch Blocked — The script is monitored but terminates within ten minutes.

• SSMGR-Stopped — Dell Networking OS stops the script by itself, if the cpu/disk-io/mem goes

beyond the threshold.

• To monitor the running script, use the watch command.

Dell#show script watch details

JobID Script Type Script Status Reset Count Watch StartTime Script NameArgs

Username

002 CONF WATCH Watch Blocked 3 Tue Dec 3 18:04:28 2013 args.pl

user2

• To control the script that is running based on the system resources such as the CPU, memory or disk

I/O usage, use the switch script limit cpu <percentage> memory <percentage> diskio

<percentage> command.

The scripting framework is enabled with system resource usage protection. Therefore, when the

system is running at a high CPU, memory or disk I/O, the program automatically suspends all the

user-configured running scripts and also prevents scheduling new scripts until the system resource

usage returns to nominal levels. The following example suspends the scripts when the CPU crosses

70, memory usage is above 60, or the disk I/O is greater than 70.

Dell(conf)#switch script limit cpu 70 mem 60 diskio 70

NOTE: For disk I/O, the /usr/pkg partition disk usage is considered.
