BIG IP LTM - Syn Cookie Monitor

Hello guys!

 

I'm making a study test and would like to know if it's possible to make a script, or something else, to show messages about the Syn Cookie... is that a way to put it in the user_alert.conf ? A message to show something like: if the syncookie is activated, a counter, show the server monitored... Is that a way to make it?

 

Thank you all!

  • Hi Adriano,

    There are a few snmp value's your what's up could query:

    sysStatHardSyncookieGen 1.3.6.1.4.1.3375.2.1.1.2.1.57

    sysStatHardSyncookieDet 1.3.6.1.4.1.3375.2.1.1.2.1.58

    sysStatHardSyncookieGen OBJECT-TYPE 
    	SYNTAX Counter64
    	MAX-ACCESS read-only
    	STATUS current
    	DESCRIPTION
    		"The number of hardware SYN cookies are generated on the system."
    	::= { sysGlobalStat 57 } 
     
    sysStatHardSyncookieDet OBJECT-TYPE 
    	SYNTAX Counter64
    	MAX-ACCESS read-only
    	STATUS current
    	DESCRIPTION

      In resume, I would like to create a graphic monitor to verify the Global Syn Check function, using the platform What's Up. Do you know if it's possible?
