F5 Virtual Servers / Pools question

Hi, In the F5 Im administering, there are 2 virtual servers on ports 7777 and 8080. Inside those I have 4 servers 2 of which, assigned to Virtual server with port 7777, are giving tomcat service on port 7777. And the servers, which are member of the virtual server with port 8080 are giving service with port 8080. Now the question is: Can I add a server giving service from port 8080 under Virtual server which uses port 7777? User > Virtual server 7777 > server 8080 Thanks.

    Hello ozdemircili,

     

     

    you sure can, provided the f5 knows what port to send traffic to from Virtual Server through to backend, you can use pretty much any port you wish. So for example you can have a HTTP virtual server listening on port 80 and a pool of web servers running on port 88, 8080 and 999 (as completely random example).

     

     

    Let us know if you have any further questions!

    Perfect. Just wanted to consult again.For now everything is fine.

     

     

    Since we are here there is another point I wonder. I want to create reports of the I/O traffic processed for every virtual server + Cpu, mem usage+ throughput and http connections.For now I only have the statistics for the day. Is there a way to get a report, let say last mont/ last year?

     

     

    Any reference as to how can be done?

     

     

    Thanks

    I believe that you would have to capture and compile that information yourself.

     

     

    To my knowledge the F5 only keeps those statistics since last Failover or Reboot.

    Can you install a copy of cacti? (CactiEZ is your friend here if you can beg/buy/borrow/steal a server or VM to install it on). There's a set of cacti templates in codeshare you can import and use those to monitor at a VS level for the stats you want. If you need further stats, you can eother create them yourself, or ask if anyone else here has already done them.

    Yes, Cacti or any other SNMP monitoring software helps yet I was referring to F5 built in reporting (if there is one). Isnt there any way using irules?

     

     

    Thanks.
