PIMU400013 update introduces two values which allow to customize time how often Parallels Infrastructure Manager (PIM) checks slave nodes availability:

   1. The slave_ping_update_timeout option defines timeout of pings between from master to slave;
   2. The slave_ping_wait_timeout option defines how long master node waits response for ping request. Status of pinged slave node is set to offline If no answer  gained.

The default value of  slave_ping_update_timeout is 120 sec, slave_ping_wait_timeout is 20. Guarantied time of detection of a slave server disconnection is slave_ping_update_timeout + slave_ping_wait_timeout seconds, by default it is 140 sec.

1. How to change the timeouts parameters by using PMC:

    By default slave_ping_update_timeout and slave_ping_wait_timeout parameters do not exist. To add them open PMC, right click on the node and choose Tasks, Manage Parallels Agent Configuration, select server_group, configuration, in the right pane add both parameters, Click Apply.

   Note: vzagent service restart is not required.

2. How to change the timeouts parameters in vzagent.conf file:

    2.1 Open vzagent.conf file

        on Windows node  - x:\vz\VZAgent\etc\vzagent.conf, where x:\ is drive where VZ folder is located,
        on Linux node - /var/vzagent/etc/vzagent.conf
    2.2 Add slave_ping_update_timeout and slave_ping_wait_timeout parameters:
        <configuration >

        < /configuration >

    2.3 Save vzagent.conf file;

    2.4 Restart VZAgent service by means service snap-in or this command on Windows: sc stop vzaop &sc start vzaop and that one on Linux: vzagent_ctl restart
