Nagios Alerts; Activate Alert Events And Notifications - Tripp Lite B092-016 Owner's Manual

Note
The Console Servers have an snmptrap daemon to send traps/notifications to remote SNMP
servers on defined trigger events, as detailed above. The Console Servers also embed the net-
snmpd daemon which accept SNMP requests from remote SNMP management servers and
provides information on network interface, running processes, disk usage, etc. (refer to Chapter
15.5 Modifying SNMP Configuration for more details).

7.1.4 Nagios Alerts

To notify the central Nagios server of Alerts, NSCA must be enabled under System: Nagios and Nagios
must be enabled for each applicable host or port under Serial & Network: Network Hosts or Serial &
Network: Serial Ports (refer to Chapter 10).
7.2

Activate Alert Events and Notifications

The Alert facility monitors the status of the Console Server and connected devices. When an alert event
is triggered, a notification is emailed to a nominated email address or SMS gateway, or the configured
SNMP or Nagios server is notified.
A wide selection of events can be used as the trigger for an alert. These events include:
 A user establishing a remote Telnet connecting to a serial port or Host.
 Reaching a nominated low-battery level on a particular UPS or current load levels on a PDU
power outlet.
 Exceeding a specified temperature or humidity level on an environmental sensor.
 Sensing a particular data pattern on a serial port (e.g. the data stream on a particular serial
console may be monitored for nominated messages coming from the device such as "warning"
or "IO error" and send out an alarm when they occur).
