HTTP request and response headers

The only way on the BIG-IP to sniff traffic is with tcpdump (or ssldump if the traffic is encrypted). This won't give a protocol breakdown but only give a raw packet dump. You'll have to wade through the output to find the headers that you want.

 

 

One other option you may consider for debugging and testing purposes is to create an iRule that logs the values you are looking for. Keep in mind that our event log is not designed for very large amounts of data so for a fully production site, this is not recommended.

I used to work with Nortel Alteon. I have been working with Bigip version 9.1.2 for three months.

 

My first question :

 

Is there a way to display the maximum connections per second for a specific VIP ?

 

Second question :

 

a active/standy or actif/actif do they keep the states (tcp, udp,..) connections in case of failover ?

 

Third question :

 

The backup file .UCS are they generated automatically or is there a way the schedule this ?

Thank a lot

 

Is there a way to display the maximum connections per second for a specific VIP ?

 

 

 

There is no way in the GUI to do this but the data is available via our iControl interfaces on a virtual by virtual basis. You can query those statistics and then calculate the difference over to poll cycles to determine the rate. With that being said, I'm not sure what plotting maximum connections per second would give you (the rate at which the maximum changes???) I guess this would guage how often you exceed the previous maximum. Most likely what you are looking for is current connections per second.

 

 

a active/standy or actif/actif do they keep the states (tcp, udp,..) connections in case of failover ?

 

 

 

I'm going to have to have you contact Product Support on this one. I don't want to give you the wrong info regarding your specific version.

 

 

The backup file .UCS are they generated automatically or is there a way the schedule this ?

 

 

 

There is no built-in way to pre-schedule configuration backups, but that is easily done. You could add the entries manually to the local cron file on the BIG-IP, or you could use an outside program along with iControl to trigger the backups (the System::ConfigSync interface is where you want to look).

 

 

Hope this helps...

Thanks for all.

 

 

Concerning keeping state of connections in case of failover, I work with Bigip version 9.1.2

Is there a way to redirect a vip when limit connection is reach depending on the status of HTTP resquest?

 

 

 

Martial

Can you rephrase your question? I'm reading it to say "Can I detect when a connection limit has been reached and then send an HTTP redirect from within the HTTP Request event?"

 

 

If so, I don't believe there is a way within an iRule to determine when you've crossed the connection limit setting on the Virtual Server. I believe the decision to either halt or reject the connection occurs before the iRules processing happens but I'll have to check on that one.

 

 

If I find out anything I'll let you know...
