Integration with Nagios Server Monitoring

Step 1 — Create the SMS Alert Shell Script

1. Create a Linux shell script in the Nagios libexec folder (default: /usr/local/nagios/libexec/). Name it smsalert.sh.
2. Paste the following content:

   #!/bin/bash
   UrlToCgi=$(printf "http://127.0.0.1/scripts/webgate.exe")
   RecipientVar=$(printf "?USER=")
   Recipient=$(printf "pageyou")
   SenderVar=$(printf "&FRM=")
   Sender=$(printf "fromme")
   MessageVar=$(printf "&MSG=")
   Message=$@
   Message=$(php -r "echo urlencode("$Message");")
   FullUrl=$UrlToCgi$RecipientVar$Recipient$SenderVar$Sender$MessageVar$Message
   wget -O- "$FullUrl"

   Update UrlToCgi to the hostname/IP of the GetWeb server. Update Recipient to the PageGate recipient or group name. Update Sender to your preferred sender name.

Step 2 — Configure Nagios Commands

1. Open commands.cfg with vi:

   vi /usr/local/nagios/etc/objects/commands.cfg
2. After the notify-host-by-email section, insert:

   # notify-service-by-sms
   define command{
   command_name notify-service-by-sms
   command_line /usr/local/nagios/libexec/smsalert.sh "--PageGate Service Alert-- Host: $HOSTNAME$, State: $HOSTSTATE$ Service $SERVICEDESC$ Description: $SERVICESTATE$ Time: $LONGDATETIME$"
   }
   
   # notify-host-by-sms
   define command{
   command_name notify-host-by-sms
   command_line /usr/local/nagios/libexec/smsalert.sh "--PageGate Host Alert-- Host: $HOSTNAME$, State: $HOSTSTATE$, Time: $LONGDATETIME$"
   }
3. Save: press Escape, then type :wq

Step 3 — Configure Nagios Contacts

1. Open contacts.cfg:

   vi /usr/local/nagios/etc/objects/contacts.cfg
2. Insert before the email section:

   service_notification_commands notify-service-by-sms
   host_notification_commands notify-host-by-sms
3. Save and restart Nagios:

   service nagios restart
