System Administration - Edit System Setup

System, Website, and Web Server Settings

Select "Setup | System Setup" in the main menu. In the "System, Website, and Web Server Settings" tab, you can define following specifics:

• Site Information: Here you can define a site name (used in the web interface and in the subject of emails), as well as the URL for the site (used for building links in emails). If you want to use a symbolic (DNS-) name to access PRTG's web server you must enter the name here.
• Scanning Intervals: Here you can define intervals which will in turn become selectable when adding objects to the installation. In order to add a new interval value merely add a numerical value followed by a time span enumerator (s/m/h/d for defining seconds/minutes/hours/days respectively).
• Uptime Threshold: With this option, you can define when a sensor goes to a red Down state. If you experience repeated fail alarms, you can expand the failure tolerance here.
• Email Options: Here you can edit the footer (for text-only mails) and HTML template that will be used for outgoing emails (placeholders allowed - more information in the "More" section below) and define whether "ToDo" emails are to be forwarded to the administrator, a specific email address or to no one at all. If "specific email" is selected, a new field appears allowing to define the email address in case.
• Data Purging Limits: Here you can select for how many days historic data remains accessible. Enter the number of days to retain historic data for each of the available entries.
• Unusual Detection: Here you can define the sensitivity of the "unusual" state detection mechanism.
• User Login Timeout: Specify the time after which a user is automatically logged out the web interface when idle.
• Settings from the PRTG Server Administrator program: These entries are "for your information" only. These entries can be edited from the PRTG Server Administrator applet under Start | PRTG program group (see PRTG Server Administrator).

Notification Delivery Settings

Select "Setup | System Setup" in the main menu. Under the "Notification Delivery Settings" tab you can define specifics relevant to notifications (see Notifications):

Note: It is important to understand that in order to use instant messaging for notifications you always need two accounts: One account that sends the messages and another one that receives the messages.

This page allows to define the following information in detail.

• SMTP Delivery: Here you can define the SMTP delivery mechanism (either use PRTG's automatic relay or define your own SMTP server or even two servers), as well as all relevant information for email forwarding. If you select to define your own SMTP server(s), you will need to provide your server's information, including the server itself (use either IP address or DNS name), the SMTP port, as well as the relay authentication type (none, standard or SASL). If you require authentication, username and password need to be provided. If you choose to set up two SMTP Relay Servers, the second server is used when the first server is not reachable (fallback server). Furthermore, it is possible to define when PRTG should start merging individual notifications, as well as provide a maximum number of notifications to be merged at any given time (this will reduce the number of mails that you will receive).
• SMS Delivery: Please choose whether to select a SMS provider from a list (and choose a provider) or choose to enter a custom URL (and enter a URL).  If you have choosen a provider from the list, enter your gateway's access username and password (and API ID if necessary). Please note: Although PRTG has built-in APIs of some SMS providers, we cannot officially provide support regarding these SMS service providers. If you have technical questions about SMS delivery beyond PRTG, please contact your SMS provider directly.
• ICQ Delivery: Provide your ICQ number ("Sender Number") and Password for the ICQ account intended to relay (not receive!) ICQ notifications.
• Windows Live Messenger (MSN Messenger) Delivery: Provide your MSN ID ("Sender Number") and Password for the MSN account intended to relay (not receive!) MSN notifications.

Probe Management

Select "Setup | System Setup" in the main menu. Under the "Probe Management" tab you can define specifics relevant to probes:

• Probe Connection Settings: Here you can define access keys, as well as allow / deny specifics IPs access to the probe(s). See Multiple Probes and Remote Probes.
• Settings from the PRTG Server Administrator program: These entries are "for your information" only. These entries can be edited from the PRTG Server Administrator applet under Start | PRTG program group (see PRTG Probe Administrator).
