    7.1.12 Routed data usage check 
    This check monitors the specified input interface for data usage that \
    is being routed through the appliance and out another 
    interface such as the Internal Cellular Modem.
    It is particularly useful in IP Passthrough mode, to detect when the downstream router has failed over an\
    d is now routing via 
    the appliance’s modem as a backup connection.
    This check may be configured with these parameters:
    • The appliance’s incoming Interface to monitor
    • An optional Source MAC/IP Address, to monitor traffic from a specific host (e.g. the downstream rout\
    er)
    • A Data Limit threshold, the Auto-Response will trigger when this is hit in the specifi\
    ed Time Period
    • The Auto-Response will resolve if no matching data is routed for the Resolve Period

    7.2 Trigger and Resolve Actions 
    To configure the sequence of actions taken in the event of the trigger \
    condition:
    • For a nominated Auto-Response - with a defined Check Condition - click \
    on Add Trigger Action (e.g. Send Email or Run 
    Custom Script) to select the action type to be taken. Then configure \
    the selected action (as detailed in the following 
    sections)
    • Each action is configured with a nominated Action Delay Time which spe\
    cifies how long (in seconds) after the Auto-
    Response trigger event to wait before performing the action. So you can \
    add follow-on actions to create a sequence of 
    actions that will be taken in the event of the one trigger condition
    • To edit (or delete) an existing action, click the Modify (or Delete) \
    icon in the Scheduled Trigger Action table 
     
    Note:  A message text can be sent with Email, SMS and Nagios actions. This c\
    onfigurable message can include selected values:  
    $AR_TRIGGER_VAL = the trigger value for the check e.g. for UPS Status, it could be on\
    batt or battlow
    $AR_VAL = the value returned by the check e.g. for ups status, it could be on\
    line/onbatt/battlow
    $AR_CHECK_DEV = the device name of the device being checked e.g. for Ala\
    rm, the alarm name 
    $TIMESTAMP = the current timestamp
    $HOSTNAME = the hostname of the console server 
    The default message text is: $TIMESTAMP: This action was run - Check details: value $AR_VAL vs trigger value $AR_TRIGGER_VAL

    Chapter 7: Alerts, Automated Response and Logging
    7.2.8 Resolve Actions 
    Actions can also be scheduled to be taken when a trigger condition has b\
    een resolved:
    • For a nominated Auto-Response - with a defined trigger Check Condition \
    - click on Add Resolve Action (e.g. Send Email or 
    Run Custom Script) to select the action type to be taken
    Note: Resolve Actions are configured exactly the same as Trigger Actions except the designated Resolve Actions are all 
    executed on resolution of the trigger condition and there are no Action \
    Delay Times set
    Configure SMTP, SMS, SNMP and/or Nagios service for alert notifications. The Auto-Re\
    sponse facility enables remote alerts to be sent 
    as Trigger and Resolve Actions. Before such alert notifications can be sen\
    t, you must configure the nominated alert service. 
    7.2.9  Send Email alerts on Resolution
    The console server uses SMTP (Simple Mail Transfer Protocol) for sending the email alert notifications. To use SMTP, the Administrator 
    must configure a valid SMTP server for sending the email: 
    • Select Alerts & Logging: SMTP & SMS 
    • In the SMTP Server field enter the IP address of the outgoing mail Ser\
    ver
    • If this mail server uses a Secure Connection, specify its type. You may also specify the IP port to use for SMTP. The default 
    SMTP Port is 25. 
    • You may enter a Sender email address which will appear as the “from”\
     address in all email notifications sent from this 
    console server. Many SMTP servers check the sender’s email address with the host do\
    main name to verify the address as 
    authentic. So it may be useful to assign an email address for the consol\
    e  server such as [email protected] 
    • You may also enter a Username and Password if the SMTP server requires authentication
    • You can also specify the specific Subject Line that will be sent with t\
    he email
    • Click Apply to activate SMTP 
    7.2.10  Send SMS alerts on Resolution
    With any model console server you can use email-to-SMS services to send S\
    MS alert notifications to mobile devices.  Almost all 
    mobile phone carriers provide an SMS gateway service that forwards email\
     to mobile phones on their networks. There’s also a wide 
    selection of SMS gateway aggregators who provide email to SMS forwarding\
     to phones on many carriers. 
    Alternately, if your console server has an embedded or externally attached cellular\
     modem you will be given the option to send the 
    SMS directly over the carrier connection.   
    						
    							130
    Chapter 7: Alerts, Automated Response and Logging
    SMS via Email Gateway
    To use SMTP SMS, the Administrator must configure a valid SMTP server f\
    or sending the email:
    • In the SMTP Settings field in the Alerts & Logging: SMTP & SMS menu se\
    lect SMS Gateway. An SMS via Email Gateway 
    field will appear
    • Enter the IP address of the outgoing mail Server SMS gateway
    • Select a Secure Connection (if applicable) and specify the SMTP port t\
    o be used (if other than the default port 25)
    • You may also enter a Sender email address which will appear as the “fr\
    om” address in all email notifications sent from this 
    console server. Some SMS gateway service providers only forward email to SMS when the \
    email has been received from 
    authorized senders. So you may need to assign a specific authorized em\
    ail address for the console server
    • You may also enter a Username and Password as some SMS gateway service providers use SMTP servers which req\
    uire 
    authentication
    • Similarly you can specify the specific Subject Line that will be sent \
    with the email. Generally the email subject will contain a 
    truncated version of the alert notification message (which is contain\
    ed in full in the body of the email). However some SMS 
    gateway service providers require blank subjects or require specific a\
    uthentication headers to be included in the subject line
    • Click Apply Settings to activate SMS-SMTP connection. 
    SMS via Cellular Modem
    To use an attached or internal cellular modem for SMS the Administrator m\
    ust enable SMS:
    • Select Cellular Modem In the SMS Settings field 
    • Check Receive Messages to enable incoming SMS messages to be received. A\
     custom script will be called on receipt of 
    incoming SMS messages
    • You may need to enter the phone number of the carrier’s SMS Message Ce\
    ntre (only if advised by your carrier or Support)
    • Click Apply Settings to activate SMS-SMTP connection
    7.2.11   Send SNMP Trap alerts on Resolution
    The Administrator can configure the Simple Network Management Protocol\
     (SNMP) agent that resides on the console server to send 
    SNMP trap alerts to an NMS management application:
    • Select Alerts & Logging: SNMP
    • Select Primary SNMP Manager tab. The Primary and Secondary SNMP Manager \
    tabs are used to configure where and 
    how outgoing SNMP alerts and notifications are sent. If you require yo\
    ur console server to send alerts via SNMP then, at a 
    minimum, a Primary SNMP Manager must be configured. Optionally, a second SNMP Network Manager with its own SNMP 
    settings can be specified on the Secondary SNMP Manager tab
    Note: Console Servers can be configured to provide status information on d\
    emand using snmpd. This SNMP agent is 
    configured using the SNMP Service Detail on Alerts & Logging: SNMP - a\
    s described in Chapter 15.
    • Select the Manager Protocol. SNMP is generally a UDP-based protocol, though it infrequently uses TCP instead.
    • Enter the host address of the SNMP Network Manager into the Manager Addr\
    ess field.
    • Enter the TCP/IP port number into the Manager Trap Port field (default =162).
    • Select the Version to be used. The console server SNMP agent supports SNMP v1, v2 an\
    d v3
    • Enter the Community name for SNMP v1 or SNMP v2c. At a minimum, a commun\
    ity needs to be set for either SNMP v1 
    or v2c traps to work. An SNMP community is the group to which devices an\
    d management stations running SNMP belong. 
    It helps define where information is sent.  SNMP default communities a\
    re private for Write and public for Read.
