Web Link monitor

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

Statistic

The number of broken or invalid links collected.

Field Descriptions

Description

This field provides a default description of the monitor. You have the ability to override the default description by adding to or replacing the text, which will then be automatically saved. 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. If the credential you need is not already present in the credentials list, use the Quick Credentials section to add a new credential.

Url

Allows you to specify the URL you want to monitor. The SolarWinds SAM variable ${IP} contained in the default value for this field attempts to monitor a web site at the IP address of the assigned node.

Accept Compression

If checked, indicates that compression is supported.

Exclusion Filter

Allows you to 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

Checking the Convert Value check box opens the Formula box. From here, you have the ability to 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 Conversion value.

Response Time Warning Threshold

This field allows you to set the warning 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.

Response Time Critical Threshold

This field allows you to 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

This field allows you to 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 setting Application Monitor Thresholds for more information.

User Notes

This field allows you to add notes for easy reference. You can access this field by using the variable, ${UserNotes}.
