NTI
Mini Server Environment Monitoring System
15
OVERVIEW
Administration
The ENVIROMUX can be administered in any one of the following ways:
•
Using Telnet or SSH protocol via the Ethernet Port.
•
Using a terminal program via the USB Console Port
•
Using the web interface (HTTP/HTTPS protocol) via the Ethernet Port.
The following administrative controls are available in the ENVIROMUX, thru the menu.
•
View or modify the administrator & user parameters (passwords, sensor alert subscriptions, admin access, etc.)
•
View or modify the network parameters (e.g. IP Address, Gateways, DNS, etc.)
•
View and clear system event logs
•
Clear, import, export and restore configuration parameters
•
Firmware upgrades for the ENVIROMUX (over Ethernet)
•
View or modify sensor, and IP device configurations
General Functions
Sensor Alerts
A high and low threshold limit can be set for each temperature or humidity sensor. When a sensor takes a reading that is outside
a threshold, an alert notification is generated. The user can specify the frequency of alert notifications to match his or her
schedule. Also, there will be some hysteresis involved with alert notifications. This means if a sensor’s readings are moving in
and out of the threshold boundaries within a configurable period of time, additional alert notifications will not be sent. After an alert
is activated, it remains persistent even if the condition of the sensors returns back to normal, until the user acknowledges or
dismisses that alert. The user has the option to set the unit to auto-clear the alert if the sensor’s status returns to normal, and the
user can be notified if the condition goes back to normal. Alert notifications will be provided through four main methods: visible
notification via one of the user interfaces (red “Fault” LED on front panel, alert on webpage, alert in text menu), emails, syslog
message and/or SNMP traps.
IP Monitoring & Alerts
Individual IP addresses can be monitored. The ENVIROMUX will ping each address, and if a response is received, the IP
address status is considered to be “OK”’. If no response, the user will have the option to configure the ENVIROMUX for an alert
will be logged and sent. The user can configure the timeout for a response and the number of retries before signaling an alert.
The ENVIROMUX can also be configured to monitor the IP addresses of the network switches and routers to which these devices
are connected, so as to determine if the problem is due to a lack of response from the device or a network failure. Alert
notifications will be provided through four main methods: visible notification via one of the user interfaces (red “Fault” LED on front
panel, alert on webpage, alert in text menu), emails, syslog messages, SMS messages and/or SNMP traps.
Event Log
The ENVIROMUX maintains an event log. The event log includes power-ON, system, and alert notifications, as well as user
login/logout, and user alert handling. The maximum number of log entries is 1000, and these entries are sorted in chronological
order. The log can be viewed at any time through the web interface or text menu, and can be saved as a text file. Log entries can
be removed individually or all at once
.
Data Log
The ENVIROMUX maintains a data log. The data log includes readings taken from sensors, IP devices, and connected
accessories being monitored. The maximum number of log entries is 1000, and these entries are sorted in chronological order.
The log can be viewed at any time through the web interface or text menu, and can be saved as a text file. Log entries can be
removed individually or all at once.
