Web Link Monitor

This SAM component monitor collects the number of broken or invalid links on a web page.

For an overview about component monitors, see Work with component monitors.

Statistic

The number of broken or invalid links collected.

Field Descriptions

Description

The default description of the monitor. If you override the default description, changes are saved automatically. The variable to access this field is ${UserDescription}.

Enable Component

Determines whether the component is enabled. Disabling the component leaves it in the application in a deactivated state not influencing either SolarWinds SAM application availability or status.

Credential for Monitoring

Select a credential that can access the password-protected portion of the web site. Click a credential in the list, or use the <Inherit credential from node> option. If the credential you need is not in the credentials list, add it in the Credentials Library. See Understand the Credentials Library for details.

Url

Specify the URL you want to monitor. The ${IP} variable contained in the default value for this field attempts to monitor a website at the IP address of the assigned node.

Accept Compression

Indicate if compression is supported.

Exclusion Filter

Create an exclusion filter if there are links the component monitor should not attempt to validate. It is a text matching filter.

Example that excludes any links to .png graphics files
Exclusion Filter: png

Ignore External Links

This option excludes external links from validation. External links are links that do not link back to the same second-level domain as the original URL.

Convert Value

Click the Convert Value check box to open the Formula box and manipulate the returned value with a variety of mathematical possibilities. You can choose common functions from the drop down lists to manipulate the returned value, or you can select the Custom Conversion option. For more information, see Convert values in data transformations for SAM component monitors.

Response Time Warning Threshold

Set the warning threshold conditions based on the response time. The response time is the time in milliseconds it takes SAM to determine that a component is not Down and to retrieve any statistical data.

Response Time Critical Threshold

Set critical threshold conditions based on the response time. The response time is the time in milliseconds it takes SolarWinds SAM to determine that a component is not Down and to retrieve any statistical data.

Statistic Threshold

Specify when a threshold that indicates a warning or critical level has been breached. Logical operators are in the drop down followed by a blank field for you to enter the value of this threshold. For example: Less than 15 for warning, Less than 5 for critical. See Application Monitor Thresholds.

User Notes

Add notes for easy reference. You can access this field by using the variable, ${UserNotes}.
