Monitoring the Replication Agents

The Replication Agents drilldown provides detailed information of all the agents that were active during the selected time range. This drilldown allows you to filter the display to show agents of selected type or a selected severity level within a certain agent type, and review all the agent’s session actions.

Figure 9. The Replication Agents drilldown.

This drilldown contains the following sections:

•
Agent type tiles — used for configuring the list displayed on the Agents table; either displaying all agents by clicking All, or filtering the display by agent type or severity level.
•
Agent table — provides detailed data regarding each of the agents or jobs selected to be displayed. For details, see Reviewing agent-specific data .
•
Sessions ran by the currently selected agent — displays all the sessions run by the agent selected in the table during the specified time range. Selecting a session on the list displays its details on the middle and right sections.
•
Details of the currently selected session — displays prominent statistics about the session currently selected on the list.
•
Agent-specific session actions data — displays actions (and merge articles, for Merge agents) for all sessions run during the specified time range by the agent selected in the Agent table. For details, see Reviewing session activity data for the selected agent .
Reviewing agent-specific data

The Agents table displays all agents whose type tile was selected on the toolbar. Each row on this table provides the following data about a specific agent:

•
Agent identification — the following agent-related data:
•
Highest severity level
•
Name
•
Type
•
Average delivery rate during the specified time range.
* 
NOTE: Hovering over this gauge displays a pop-up that contains a description of the flow, and a chart that shows the relevant data plotted over the specified time range.
•
Operation start time
•
Entities involved in the publishing process — provides the names of the following components:
•
Publishing server
•
Publication database
•
Publication
•
Subscribing server
•
Subscription database

Except for agents of type Misc. Jobs, clicking each agent row displays the sessions ran by the selected agent during the specified time range. For details, see Reviewing session activity data for the selected agent .

Reviewing session activity data for the selected agent

The lower section of the Replication Agents drilldown displays agent-specific session data for all agents whose type is other than Misc. Jobs.

To view the session actions of a single agent:
1
Click the requested agent’s row on the Agents table.
Session data is retrieved only on demand by clicking a button or link, or by refreshing a screen component. The initial display of the Session section provides no data on the Sessions Actions pane.
Figure 10. Click this link to retrieve action data.
* 
NOTE: When the selected agent’s type is Merge, the Sessions section also displays the Session articles.
2
To retrieve action data for the first session on the session list, click the link under the message title.
To retrieve action data for any other session, click the requested session on the session list on the left.
The retrieved data is displayed on a detailed list of all actions performed by the session during the specified time range, indicating the time the action took place, and the action message.

Monitoring the Replication Subscriptions

The Replication Subscriptions drilldown allows performing an in-depth analysis of all subscriptions servers by the selected distributing instance.

To investigate the requested subscription:
1
Select which subscription type to display, by selecting the tile that represents the requested type: Snapshot, Transactional, Transactional with update, Merge or All.
* 
IMPORTANT: In each of these tiles, it is possible to filter the display to show only subscriptions with a specific severity status, by clicking the icon that represents that status. For example, Not Started.
2
Review the requested publication data on the Subscriptions table:
•
Severity — the highest (worst) severity level
•
Status
•
Subscribing server name
•
Subscription database name
•
Subscription type — Pull, Push, or Anonymous
•
Publication name
•
Publishing server name
•
Publication database name
•
Publication type
•
Agents taking part in the transaction — Log Reader, Queue Reader, and Snapshot agents

Click the subscription’s row to access the Subscription Details screen.

The Subscription Details Screen

The Subscription Details screen allows tracking the process of replicating data to the selected subscription, by displaying all components involved in the process and providing links for further investigation.

Figure 11. The Subscription Details screen.

Similar to the Replication home page, this screen contains the following panes, each representing a stage at the replication process:

•
Publisher — provides the publication-related data that appears on the Replication home page, that is, publishing server, publication database, and publication name, and the following data:
•
Type
•
Latency
•
Status — can have one of the following values: Running, Failed, Retrying, Idle, and Not started.
•
Agents used by Publisher — displays the replication agents used for replicating the publication data to the subscribing server.
The agent types displayed on this pane for each publication type are as follows:
•
In snapshot, Transactional and Merge publications — Snapshot and Log Reader.
•
In Transactional with update publications — Snapshot, Log Reader, and Queue Reader.
* 
IMPORTANT: To carry out an in-depth analysis of the agent’s actions using the Replication Agents drilldown, click the requested agent’s row. The Replication Agents drilldown appears, with the clicked agent’s row selected in the All Agents table. For details, see Monitoring the Replication Agents .
•
Subscriber — provides the following data regarding each of the publication’s subscriptions:
•
Subscribing server
•
Subscription database
•
Subscription type — Push, Pull, or Anonymous. For further details, see glossary definitions for Pull subscription , Push subscription , and Anonymous subscription .
•
Subscription status — can have one of the following values: Running, Failed, Retrying, Idle, and Not started.
•
Sessions — provides agent-specific session data for all agents taking part in the selected subscription process. If the process involves more than one agent, this section is divided into the following panes:
•
Publisher to Distributor — displays the session actions of the Snapshot or Log Reader agent.
•
Distributor to Subscriber — displays the Distribution agent’s session actions.

Monitoring Alarms

The Alarms pane contains a table that displays only replication-related alarms, invoked if the metrics defined in the replication-related rules have been exceeded during the specified time range (by default: the last 60 minutes). For a detailed list of such alarms, see Replication-related alarms .

Unlike the Alarms pane on the Foglight for SQL Server home page, which always displays all alarm types, this table allows alternating between two display methods:

•
Displaying all alarms — by clicking All.
•
Filtering the alarm display by severity level — by clicking a specific severity level.
* 
IMPORTANT: Fatal alarms are invoked when the SQL Server agent stops responding, and are not due to replication errors. Therefore, the count of alarms whose severity level is Fatal (indicated in red) should always remain 0. The alarm display should be filtered by clicking either the Warning or Critical severity level.
* 
NOTE: To view detailed information regarding each alarm, go to the Replication Agents drilldown.
Figure 12. Alarm Indicator Descriptions
Indicator
Description
Yellow (Warning)

The metric (or workload resource) has exceeded the configured threshold or deviated from the baseline.

Orange (Critical)

The metric (or workload resource) has exceeded a threshold or extremely deviated from the baseline.

Red (Fatal)

The SQL Server is not responding, triggering a fatal alarm.

Replication-related alarms

The replication-related alarms are as follows:

•
Replication Agents - Delivery Latency — invoked when the delivery latency for a specific instance exceeds a predefined threshold.
•
Replication Agents - Status — invoked when the replication agent fails to start.
•
Replication Publications Due to Expire — invoked when the number of hours left until the replication publications are due to expire falls below a predefined threshold.
•
Replication Publications - Errors — invoked when an error is encountered in one of the replication publications.
•
Replication Publications - Status — invoked when a replication publication fails to start.
•
Replication Subscriptions - Status — invoked when a replication subscription fails to start.
•
Replication Available — invoked when the replication process has encountered a failure.

For details, see the Foglight for SQL Server Reference Guide.

Monitoring SQL Performance

The SQL Performance page provides the ability to investigate the activity and resource consumption of a selected instance. There are two levels of metrics available:

•
Without SQL PI configured — basic History, lock analysis data, and activity highlights. See Monitoring SQL Performance without SQL PI configured
•
With SQL PI configured — The ability to perform a more in-depth analysis and investigation of the Instance activity and resource consumption by adding a dimension view of the activity, change tracking analysis, execution plan analysis and compare toll. See Monitoring SQL Performance with SQL PI Configured .

The SQL Performance page displays the following components:

•
The Instance View — Provides the ability to investigate and analyze the resource consumption of the instance.
•
The Resource toolbar — By selecting one of the resources, the resource consumptions charts and the overview section are updated to display only the relevant information regarding the activity of the selected resource.
