Documentation forServer & Application Monitor
Monitoring your applications and environment is a key capability of Hybrid Cloud Observability and is also available in a standalone module, Server & Application Monitor (SAM). Hybrid Cloud Observability and SAM are built on the self-hosted SolarWinds Platform.

Connections

This widget contains monitors specific to the current status of the active connections for the current IIS website. The icons of the listed performance counters in the Statistic Name column change colors to reflect the listed counter's current state. Clicking any performance counter in the Statistic Name column takes you to the Performance Counter Details page for that performance counter.

If the value of a listed performance counter crosses the Warning threshold, the chart for the listed counter displays a yellow background. If the value of a listed monitor crosses the Critical threshold, the chart for the listed counter displays a red background. Hovering over any time period within the chart displays detailed information about that time period in the tooltip. Hovering over a counter gives you detailed information about that performance counter.

Counter Description

Total Connections Attempts

The total number of connections to the Web or FTP service that were attempted since service startup. The count is the total for all websites or FTP sites combined, regardless of what you choose for the instance.

This number does not include connection attempts that failed at the TCP (transport) or IP (network) layer.

Total Logon Attempts

The total number of successful logons to the Web or FTP service since the service started.

This does not include failed logon attempts.

Current Connections

The current number of connections established with the Web service.

This is the sum of both nonanonymous (authenticated) and anonymous (unauthenticated) users.

Possible problems:
If this number is at or near the maximum allowable connections, the Web service is at full capacity.

Remediation:
If the value is too high for a particular IIS server, then load balancing or clustering technologies can be applied to lower the burden of the server in question. Also, check the Web Site property page for the maximum connection limit.
Current Anonymous Users

The number of users who currently have an anonymous connection using the Web service.

If anonymous connections are not permitted on the server, the value of all anonymous user counters is always zero.
Current Non-Anonymous Users

The number of users who currently have a non-anonymous connection using the Web service.

If authentication is not enabled on the server, and none of the applications that run on the server request or require authentication, then the value of all nonanonymous user counters is always zero.

Zooming

You can have the chart show a predetermined time period of data by clicking on any one of the three Zoom buttons in the head of the Zoom column. Alternatively, you can have the chart show a specific date range by dragging the mouse over an area of the chart. The time and date displayed at the top of the widget shows the amount of data currently loaded into the chart. This can be changed by clicking Edit from within the widget.

The Value from Last Poll column shows the most recent data available for the listed statistic.
