Alerting
Sentry enables real-time alerts to indicate if content within a stream is invalid, a stream goes down, or user
thresholds are exceeded. Alerts are visible within the web user interface (Alert History) and can be sent via
email and SNMP trap. There are three major alert types:
Thresholds
Alert when a given bandwidth level or cycle time has exceeded or falls below on a PID, program, table,
DSM-CC, or BFS. Alert when a program’s PCR arrival interval or PCR jitter has exceeded or falls
below a given level.
Thresholds with Frequency
Alert when a given threshold condition is met and it has occurred twice or more in a given time period.
Content
Alert when a selective piece of content has been received or transmitted correctly or incorrectly. Alert
when a given PID or program is active or not-active. Alert if a PID, program, table, DSM-CC, or BFS
drops. Alert if audio silences or video freezes.
Refer to the Configuring Alerts section for more information.

Page Title Bar
The title bar identifies the name of the page currently in view.
Thumbnails
Current Status also features thumbnail visual confirmation of the content of each program or service. You
can control the size of the thumbnail at the top of the column. You can also refresh the thumbnail manually or
it will refresh automatically every 5 minutes. Settings for thumbnails can be found in System Preferences.
Group Tabs and Input Ports
Input ports indicate the sources of transport stream input, which can be either ASI (one or four ports) or GigE
(MPEG over IP unicast IP port or up to 30 multicast groups, each consisting of a Group ID and an IP Port).
Sentry allows you to organize input ports into system and user groups. You must have Administrator privilege
to create and modify system groups.
If the number of input ports is greater than one, then default system groups will be automatically created (two
groups for a four port Sentry and four groups for Sentrys with more than four ports). Settings that the user has
specifically saved are retained as they navigate from page to page.
For example, the figure below shows the groups and ports of a GigE Sentry. The Group 3 tab is selected
showing that Ports 16 through 23 are in Group 3. Selecting a group will report only on the data from the ports
in that group. Ports can also be renamed.
