Too many connections established

  • Description:
    Hide

    During load tests in the cloud with Roboconf we can see that too many connections are established by the NIO transporter.

    Number of connections of the NIO transporter accepted by container-bootstrap from (Petals ESB containers are not restarted between 2 runs):

    Container Nb connection established during the 1st run Nb connection established during the 2nd run
    container-1 317 15
    autonomic-0 105 9
    autonomic-1 35 9
    autonomic-2 10 9
    autonomic-3
    		10

    After the 2nd run, the number of connections coming from container-bootstrap into:

    Container After the 2nd run
    container-1 1694
    autonomic-0 965
    autonomic-1 544
    autonomic-2 341
    autonomic-3 17

    I think there are a lot of connection established, and this has impact on performances

To improve the statistics mentioned (that are based on content of log files), we can add metrics about connections of the NIO transporter at container level: PETALSESBCONT-395

The metrics about connections show that a lot of connections are established without any reason:

This issue should be solved with PETALSESBCONT-437 (Reimplement the Remote TCP transporter with Apache Netty)
