This problem appears when the first package from the ping execution doesn’t reach the recipient.
icmp_checks parameter is set as
1 inside the Server Configuration File (Default path:
/etc/pandora/pandora_server.conf) it will show critical value because it only considers the first try at sending the ping command.
Module status would be also critical if the
icmp_checks value is higher than
1,the reason for this is that this parameter only executes “independent” pings so check results would always be wrong.
A solution would be to use a script which executes a ping sending as many packages as we want upon its execution. So that, if a machine doesn’t answer to the first package we could fix it by modifying the script with a number of packages higher than 1, that way the result will be successful.
