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 command show system storage at DUT0 and expect this output:
Show output
Total: 8144384 Free: 7854668 Used: 289716
Step 2: Set the following configuration in DUT0:
set service ssm log-level notice set service ssm operation OPER_STO interval 0.05 set service ssm operation OPER_STO description 'OPER_STO operation description' set service ssm operation OPER_STO type storage set service ssm operation OPER_STO alarm ALARM_STO activate value 581556 set service ssm operation OPER_STO alarm ALARM_STO deactivate value 494004.0 set system alarm ALARM_STO
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 581556K, since the value of the current used storage is 289716K and the size of the new file to be downloaded is 291840K. 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 494004.0K.
Step 3: Run command service ssm operation show at DUT0 and check if output contains the following tokens:
OPER_STOShow output
----------------------------------------------------------------------------------------------- Operation Type Last-Value Alarm Activate Deactivate Status Toggled Prev-toggled ----------------------------------------------------------------------------------------------- OPER_STO storage 289716.00 ALARM_STO 581556.00 494004.00 false
Step 4: Run command system alarm ALARM_STO show at DUT0 and check if 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 command service ssm operation OPER_STO show at DUT0 and check if 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 289716.00 ALARM_STO 581556.00 494004.00 false
Step 6: Run command service ssm operation show at DUT0 and check if 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 289716.00 ALARM_STO 581556.00 494004.00 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: Set the following configuration in DUT0:
set interfaces ethernet eth0 address 10.215.168.50/24
Step 8: Ping 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=0.280 ms --- 10.215.168.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.280/0.280/0.280/0.000 ms
Step 9: Run command file copy http://10.215.168.1/~robot/os_iso_v3.3.1.2.iso running:// force at DUT0 and expect this output:

Step 10: Run command file show running:// at DUT0 and check if 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 command show system storage at DUT0 and expect this output:
Show output
Total: 8144384 Free: 7563452 Used: 580932
Step 12: Run command show system storage at DUT0 and expect this output:
Show output
Total: 8144384 Free: 7562828 Used: 581556
Step 13: Run command system alarm ALARM_STO show at DUT0 and check if output matches the following regular expressions:
(ALARM_STO)\s+(true)Show output
-------------------------------------------------------------------------------------- Alarm Status Toggled Prev-toggled Toggle-count Time up (%) -------------------------------------------------------------------------------------- ALARM_STO true 2023-11-23 22:48:26.113096 1 18.11

------------------------------------------------------------------------------------------------------------------ Operation Type Last-Value Alarm Activate Deactivate Status Toggled Prev-toggled ------------------------------------------------------------------------------------------------------------------ OPER_STO storage 581556.00 ALARM_STO 581556.00 494004.00 true 2023-11-23 22:48:26.113096
Note
The previous command output should show that the alarm is activated, since the storage used has increased after downloading the new file.
Step 16: Delete a file by running file delete running://os_iso_v3.3.1.2.iso.
Note
With the previous command, the downloaded file is deleted, thus causing a decrease in the storage used.
Step 17: Run command show system storage at DUT0 and expect this output:

-------------------------------------------------------------------------------------------------------------------------------- Operation Type Last-Value Alarm Activate Deactivate Status Toggled Prev-toggled -------------------------------------------------------------------------------------------------------------------------------- OPER_STO storage 581556.00 ALARM_STO 581556.00 494004.00 false 2023-11-23 22:48:28.228774 2023-11-23 22:48:26.113096
Step 20: Run command service ssm operation show at DUT0 and check if 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 289716.00 ALARM_STO 581556.00 494004.00 false 2023-11-23 22:48:28.228774 2023-11-23 22:48:26.113096
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.
