Overview

The primary aim of the Standard knowledge base in Sentinel3G is to provide for some basic connectivity monioring. This document describes the general content of the Standard knowledge base, and the discrepancies between them on different platforms.

Standard Knowledge Base Settings

The following settings are global and affect the behaviour of sentinel3G. Ensure you restart the Host Manager after changing any of these settings.

Setting Description
Debug Whether Host Monitor debugging is enabled. The default value is no.
EventHost The host that this Host Monitor sends events to. This setting is requested the first time the sentinel3G console is started. If you change the EventHost setting, you must restart the Host Monitor.
HostmonAccess If this host is a sentinel3G Event Manager, this specifies which hosts can connect as Host Monitors. The default value is Domain (hosts in the local domain are trusted). Other options are: None (only hosts in Hostinfo are trusted), and All (all hosts are trusted).
NotifyList The default list of people to to notify when a sentries' severity is NotifySeverity or higher.
NotifyMessage The message body template for notifications. The default value is 'Sentry $SentryName is in $State state ($Severity):\n $ConsoleText'
NotifySMS The message text template for SMS notifications. The default value is '[string totitle $Severity]: sentry $SentryName $State at [clock format $Since -format %H:%M] - $ConsoleText'
NotifySeverity The default minimum severity for notification to occur. The default value is alarm severity.
NotifySites Notification hosts(???)
NotifySubject The message subject template for notifications. The default value is '[string totitle $Severity]: sentry $SentryName $State at [clock format $Since -format %H:%M]'
Polled Whether this Host Monitor is polled by the Event Manager. Normally the Host Monitor connects to the Event Manager. Sometimes, due to security policies, a firewall may block such a connection. However, opposite direction connection is possible, so the Host Monitor is configured to be polled by the Event Manager instead. The default value is no, the Host Monitor connects to the Event Manager. If you change the Polled setting, the PolledHosts setting must be changed on the Event Manager host to include this host, and you must restart both the Host Monitor and the Event Manager.
PolledHosts The list of hosts that cannot connect to the Event Manager running on this host. If you change the PolledHosts setting, you must restart the Event Manager.
ProxyExcludes Hosts to exclude from the proxy(???)
ProxyHost The name of the proxy host(???)
ProxyInfo (???)
ProxyPort (???)
RefSites
RefSitesOptions
RefSitesPort
RefSitesTimeout
