CLI support for SmartSwitch PMON #3271

rameshraghupathy · 2024-04-14T23:30:23Z

What I did

Enhanced the following CLIs to support SmartSwitch PMON as described in the PMON HLD documentation "https://github.com/sonic-net/SONiC/blob/d19d8933a43d0a31a4f3b2310f4336f289bca340/doc/smart-switch/pmon/smartswitch-pmon.md"

CLIs:
Added new module "DPUX" support for 1 and 2 below
1. "config chassis module startup DPUX" , where X could be 0, to the maximum number of DPUs-1 in the SmartSwitch chassis
2. "config chassis module shutdown DPUX"

Extended the following CLIs to support the new module "DPUX" and also provided the "all" option to display the reboot-cause of the "NPU" and all "DPU" modules.
1. "show reboot-cause" will remain the same and added "show reboot-cause all"
2. "show reboot-cause history" will remain the same and added "show reboot-cause history <module-name>", where module name could be DPUX, and all.

Added a new sub command "show system-health dpu <module-name>", where module name could be DPUX, and all. This new subcommand will provide additional DPU state details as mentioned in the HLD

How I did it

Kept the original CLI output unaltered
Added sub command to support SmartSwitch "DPUs"
Added additional code in chassisd, and in platform modules.py, chassis.py to support it
Updated the DB tables as mentioned in the PMON HLD

Fixes: sonic-net/sonic-buildimage#21372

How to verify it

Build an image with the required files (refer to the other upstream PRs and the platform PRs)
Require files:
- This PR including reboot_cause.py, chassis_modules.py, system_health.py)
- The other PR including module_base.py, chassis_base.py, docker-pmon.supervisord.conf.j2, chassisd, mock_module_base.py, and the appropriate database_config.json
- Platform "platform-cisco-8000" supporting PMON (module.py, chassis.py, inventory.py, pmon_daemon_control.json, and the required DB changes)
Run the CLIs and see the new output

@vvolam There was a formatting issue due to which the preview wasn't showing "". Fixed it.

doc/Command-Reference.md

@rameshraghupathy in all these sample examples can you specify where the CLI is being executed. NPU or in the DPU host.

@prgeor Added samples, in missing places

doc/Command-Reference.md

+  show reboot-cause all
+  ```

+- Example:


@rameshraghupathy please also capture the CLI output specifically when run inside DPU (even though its same as fixed chassis)

@prgeor Added the CLI output when run on DPU

+    key = key + suffix
+    keys = chassis_state_db.keys(chassis_state_db.CHASSIS_STATE_DB, key)
+    if not keys:
+        return


@rameshraghupathy how will the user know the CLI failed? How will the script know if the return code is not zero?

@prgeor Added an error message to indicate the DPU_STATE table doesn't exist for the module in the DB.
