When sync status change show in log

Hello,

Is it possible for F5 to show up "sync status change"in the log when the sync status changes?
I tried to change the sync status and found that the information is not shown in the log.

Any help is appreciate.

    Hi Michael,

    I'm uncertain if a more agressive MCPD log level may include some log messages for sync-status-changes? You may give it a try...

    If everything fails you could simply produce your own log lines as needed via custom iCall scripts. The quickly coded iCall script executes every 120 seconds a "tmsh show cm sync-status" and then checks if the resulting text output contains the string "Color green",  if the string is not present, it will simply create a log entry for you...

     

    sys icall handler periodic check_config_sync {
    interval 120
    script check_config_sync
}

sys icall script check_config_sync {
   app-service none
   definition {
		tmsh::log_dest file
		tmsh::log_level debug
		if { [tmsh::show /cm sync-status] contains "Color    green" } then {
			# Everything is fine... 	
		} else {
			tmsh::log debug "Check Config Sync: [info hostname] displays a non-green sync-state."
		}
   }
   description none
   events none
}

     

    Cheers, Kai

      Hello Kai_Wilke , 
      I wonder if configsync.autodetect still supported. 
      I think if he modified " db configsync.autodetect" value to be enabled , I think he will get an informative log message within /var/log/ltm. 

      I tried to test it on my lab but i do not find this option.

        Hi Mohamed,

        beginning with TMOS v11 the cluster management has completely changed.

        I highly doubt that any of those cluster related KB information written for previous TMOS versions still apply. It was a completely different world back then...

        Cheers, Kai

      Hi Mohamed_Ahmed_Kansoh,

      Thanks for your reply.

      Maybe my expression was not clear and made you misunderstand.
      I mean when the sync status changes, can I see the log with the status change on var/log/ltm?

      I tried to change the sync status and found that the information is not shown in var/log/ltm.

        hello , 
        you can see the " Sync " action in "/var/log/ltm" , you see a log related to mcpd process contains the commit id , time , ..etc , but this when you click sync button. 

        I do not know if the status changed to " changes pending " shoud give you a log or not. 
        let us see one of F5 experts here can provide you a good reply in this. 

        But I want to ask you , why do you want to see this log , it wouldn’t be useful for anything , you can see the status cleared within cli or GUI as well. 

        Regards
