[manuel capmedia]

hi,   I have a problem with an alert which was used in the old file configuration mon.cf.   I explain :   indeed in the first configuration, I perform one test on router and start an alert on two email adresses :   HOSTGROUP router_n adresse_ip ....    watch router_n     service ping      interval 5m         monitor fping.monitor         period wd {Mon-Fri} hr {7am-10pm}         alert mail.alert adress1@domain adress2@domain   but in the new configuration the adress ip of this router has changed and alert message is send on only one email adress:   HOSTGROUP router_n new_adresse_ip ....    watch router_n     service ping      interval 5m         monitor fping.monitor         period wd {Mon-Fri} hr {7am-10pm}         alert mail.alert adress1@domain     the problem is that from time to time I receive alert messages of the old configuration which doesn't exist in the new file configuration mon.cf.   I don't understand what is the problem???   Thanks to your response.
