Ssm
The following scenario shows how to configure different SSM (System Service Monitoring) operations. SSM operations can be used to monitor several system states (e.g., CPU, memory, storage and temperature), activating or deactivating previously defined alarms when the monitored states reach certain threshold values.
Monitoring Storage
Description
In this scenario an SSM operation is configured in DUT0 to monitor the storage state of the system and activate or deactivate an alarm when said state reaches a defined threshold value. First, the alarm is activated when a new file is downloaded. Then the alarm is deactivated when the downloaded file is deleted.
Scenario
Step 1: Run the command show system storage on DUT0 and expect the following output:
Show output
Total Storage: 7.767 GB Free Storage: 7.365 GB Used Storage: 411.312 MB
Step 2: Set the following configuration in DUT0 :
set service ssm log-level notice set service ssm operation OPER_STO alarm ALARM_STO activate value 426180.25 set service ssm operation OPER_STO alarm ALARM_STO deactivate value 422848.75 set service ssm operation OPER_STO description 'OPER_STO operation description' set service ssm operation OPER_STO interval 1 set service ssm operation OPER_STO type storage set system alarm ALARM_STO set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Note
To emulate an increase in storage usage, a file with a known size could be downloaded. To activate the alarm with this increase in storage used, the alarm activation threshold must be adjusted with the value resulting from adding the current used storage and the size of the new file to be downloaded. In this example, the value set as the activation threshold is 426180.25K, since the value of the current used storage is 421183K and the size of the new file to be downloaded is 6663K. Also, to emulate a decrease in storage used, the previously downloaded file could be deleted. To deactivate the alarm with this decrease in storage used, the alarm deactivation threshold must be adjusted with the value of the storage used before downloading the new file. In this example, the value set as the deactivation threshold is 422848.75K.
Step 3: Run the command service ssm operation show on DUT0 and check whether the output contains the following tokens:
OPER_STOShow output
----------------------------------------------------------------------------------------------- Operation Type Last-Value Alarm Activate Deactivate Status Toggled Prev-toggled ----------------------------------------------------------------------------------------------- OPER_STO storage 421184.00 ALARM_STO 426180.25 422848.75 false
Step 4: Run the command system alarm ALARM_STO show on DUT0 and check whether the output matches the following regular expressions:
(ALARM_STO)\s+(false)Show output
------------------------------------------------------------------- Alarm Status Toggled Prev-toggled Toggle-count Time up (%) ------------------------------------------------------------------- ALARM_STO false 0 0.00
Step 5: Run the command service ssm operation OPER_STO show on DUT0 and check whether the output matches the following regular expressions:
(OPER_STO)\s+(storage)[\s\d.]+(ALARM_STO)[\s\d.]+(false)Show output
----------------------------------------------------------------------------------------------- Operation Type Last-Value Alarm Activate Deactivate Status Toggled Prev-toggled ----------------------------------------------------------------------------------------------- OPER_STO storage 421184.00 ALARM_STO 426180.25 422848.75 false
Step 6: Run the command service ssm operation show on DUT0 and check whether the output matches the following regular expressions:
(OPER_STO)\s+(storage)[\s\d.]+(ALARM_STO)[\s\d.]+(false)Show output
----------------------------------------------------------------------------------------------- Operation Type Last-Value Alarm Activate Deactivate Status Toggled Prev-toggled ----------------------------------------------------------------------------------------------- OPER_STO storage 421184.00 ALARM_STO 426180.25 422848.75 false
Note
The previous command output should show that the operation has been created successfully and that the alarm is desactivated, since the storage used has not yet increased.
Step 7: Modify the following configuration lines in DUT0 :
set interfaces ethernet eth0 address 10.215.168.64/24
Step 8: Ping the IP address 10.215.168.1 from DUT0:
admin@DUT0$ ping 10.215.168.1 count 1 size 56 timeout 1Show output
PING 10.215.168.1 (10.215.168.1) 56(84) bytes of data. 64 bytes from 10.215.168.1: icmp_seq=1 ttl=64 time=0.453 ms --- 10.215.168.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.453/0.453/0.453/0.000 ms
Step 9: Run the command file copy http://10.215.168.1/~robot/ssm_test_file running:// force on DUT0 and expect the following output:
Show output

Step 10: Run the command file show running:// on DUT0 and check whether the output contains the following tokens:

Note
With the previous command, a file with a known size is downloaded, thus causing an increase in the storage used.
Step 11: Run the command show system storage on DUT0 and expect the following output:
Show output
Total Storage: 7.767 GB Free Storage: 7.359 GB Used Storage: 417.824 MB

Note
The previous command output should show that the alarm is activated, since the storage used has increased after downloading the new file.
Step 15: Delete a file by running file delete $running://ssm_test_file.
Note
With the previous command, the downloaded file is deleted, thus causing a decrease in the storage used.
Step 16: Run the command show system storage on DUT0 and expect the following output:
Show output
Total Storage: 7.767 GB Free Storage: 7.365 GB Used Storage: 411.316 MB
Step 17: Run the command system alarm ALARM_STO show on DUT0 and check whether the output matches the following regular expressions:

Step 19: Run the command service ssm operation show on DUT0 and check whether the output matches the following regular expressions:
(OPER_STO)\s+(storage)[\s\d.]+(ALARM_STO)[\s\d.]+(false)Show output
-------------------------------------------------------------------------------------------------------------- Operation Type Last-Value Alarm Activate Deactivate Status Toggled Prev-toggled -------------------------------------------------------------------------------------------------------------- OPER_STO storage 421188.00 ALARM_STO 426180.25 422848.75 false 1784898368.222283 1784898367.202577
Note
The previous command output should show that the alarm is deactivated, since the storage used has decreased after the deletion of the downloaded file.
