F5 load balancer with siteminder for BootStrap

    Hi All,

     

    I wanted to know your thoughts about how to achieve monitoring of policy server's behind a load balancer, we are going to use LB's for just BootStrapping policy servers. Going through the documentation it says that ideally you should use an API call to do a healthcheck  rather than  TCP connect against the policy server ports.  What are you using in yours and whats the downsize of each of the approaches.

     

    If i use a script , does is protected suffice or doing an Auth and Az is a complete test to check the health of policy servers.

     

    Thanks

    Would not recommend TCP on the SiteMinder ports.  These are the ports trusted hosts use with encrypted shared secrets.  These queries are likely to generate many "failed handshake" type messages on your policy server smps logs.

     

    We execute a perl api script which does a real Authentication using a "localhost" HCO.  Our monitoring tool then does an SNMP query to check how long the login takes.

    Thanks

    Hi,

     

    I just got perl script implemented to check the bootstrap of policy server. I am looking for some guidance on how to enable it on F5 Load Balancer.

     

    Thanks,

    Sanjay

    You can try to call this from a shell script and ask F5 to run that Script based on the success failure you can predefine what you want to return in each case to F5, At least that is what i am trying to do , still not complete yet

    Hi,

     

    Thanks for your help. My F5 admin is saying it can NOT execute perl script and .not advisable to run shell script. So would you please share more details on what exactly you setup on F5, it will be a great help.

     

    My shell script, produes following output.

    On Success, we get following output

    Fri Jul  3 09:35:01 2015 Success, is Protected, Authentication, Authorization

    On Failure, we get following output

    Fri Jul  3 10:00:02 2015 ERROR: Failed to connect to policy sever with error code -3

     

    Thanks,

    Sanjay

    I am working on it with my F5 admin's , haven't reached a solution yet .  approach mentioned above is what we aree trying to follow to run a script , its still an ongoing discussion.

     

    Thanks

    Any updates? 

     

    Is F5 capable of calling a shell script which invokes a perl script?   If so, it seems calling the perl script directly would be just as easy...

    Hi,

     

    unfortunately F5 can not execute perl scripts or sh scripts in our env. so an alternate java based health check script is under progression.

     

    Thanks,
