Delivering Triggered Alerts
AirWave uses Postfix to deliver alerts and reports via email because it provides a high level of security and queues
email locally until delivery. If AirWave is located behind a firewall, preventing it from sending email directly to a
specified recipient, use the following procedures to forward email to a smarthost.
1. Add the following line to /etc/postfix/main.cf:
relayhost = [mail.example.com]
where mail.example.com is the IP address or hostname of your smarthost
2. Run service postfix restart.
3. Send a test message to an email address:
Mail -v user@example.com
Subject: test mail
.
CC:
4. Press Enter.
5. Check the mail log to ensure mail was sent:
tail -f /var/log/maillog

Description
Disk Usage This trigger type is based on the disk usage of AirWave. This type of trigger indicates that disk usage for the
AirWave server has met or surpassed a defined threshold. Select Add New Trigger Condition
to specify the
disk usage characteristics that trigger an alert.
Set one of these triggers at 90% so you receive a warning before AirWave suffers performance degradation
due to lack of disk space.
