  • 1.  Problems with PPack for WebServers 10.3

    Posted Dec 01, 2016 11:11 AM

    Hello Community.

    I have a problem with some webserver upgraded with TLS1.2

     

    Now I cannot monitor the webservers and I get this error

     

    12/01/16 05:05:22 PM CET [ERROR] [WebServerMonitor] Could not get metrics from server : https://x.x.x.x:443 Could be due to unsupported protocol or cipherSuite being used

    Do you have an idea how to solve this?

     

    Thanks

    Take a look at the wiki for the version you are using and compare the supported cyphersuites.

    Ciao Luca,

     

    In addition to Davis' suggestion please check below TEC DOC that seems to match the error you are having:

     

    Knowledge Base Articles 

     

    Not seeing Web Server metrics.

     

    Cheers

    Hello community.

    The problem is solved.

    We had an error because we started the PowerPack with jre 1.6.

    Now we have started the PP with java 1.7 and magically everything goes right. The https Connection was done using jre1.6 and this did not support TLS1.2. Now with jre 1.7 TLS v1.2 is supported.

     

    Thanks
