Service Manual

The following example shows how you can schedule the script named sample.zsh to start after one

hour and 12 minutes from now and runs the script in the background:

Dell#script execute sample.zsh start 01:12 bg

• Schedule a script to run periodically.

Schedule scripts to run at a certain time, to be repeated, to stop at a specified time or by a string of

arguments. This script runs in the background.

CONFIGURATION mode

script execute script-name [start {at date-time | after time}] [stop {at

date-time | after time}] [watch] [arguments arg[..arg]] [username username]

Following example shows the script execution at 22:22 (FTOS clock time) and stops after 15 minutes:

Dell(conf)#script execute monitor_status.pl start at 22:22 stop after 15

watch args "Te 0/4"

The keyword watch is used to monitor the script. If the script execution terminates before 10

minutes, the system will rerun the script.

• Executing a script based on event trigger.

Define an event to trigger scripts to run by a log event (for example, SYSLOG in Dell Networking OS), a

time-based event, or when CPU or memory usage reaches a predetermined percentage. The script

runs in the background.

CONFIGURATION mode

script trigger-event event-name {log-event [{tag—or—ex tags | tag-and-ex

tags}] [severity severity level]} | time-event {[start {at date-time | after

time}] [stop {at date-time | after time | count number}] [interval time]

[weekday day] [ month month] [monthday nday]} | cpu-usage percentage | mem-

usage percentage}

Following example shows the event to trigger a script at 22:22 and then triggers every Monday

midnight and stops at 02:02–11/10/14:

Dell(conf)#script trigger-event Event2 time-event start at 22:22 stop at

02:02-11/10/14 weekday mon

Following example shows the event triggering the script once the cpu-usage reaches 30%:

Dell(conf)#script trigger-event event1 cpu-usage 30

Following example shows how you can define the event to trigger a script when a SYSLOG event with

the OSTATE_UP pattern occurs:

Dell(conf)#script trigger-event Port_State_Event log-event tag tag-regex

"OSTATE.*up"

Following example shows how you can define the event to trigger a script even if any one of the

pattern is matched:

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

ex "Major alarm" "Minor alarm"

• Schedule a script to run based on defined events.

Schedule a script to provide mapping between the scripts and trigger-events.

CONFIGURATION mode
