Has anyone ever tried to capture web content for an alert in SAM?

The requirement seems simple enough in Server & Application Monitor: 

1. Monitor an HTTPS url, such as: https://foo.bar/1

That's a plain text page with a bunch of technical data... if the STATUS line text = warning or critical, send an alert. That's easy enough. The native HTTPS MONITOR module, do a search string, fail if found, done in one.

2. Have the failure alert email to also include the full text output of https://foo.bar/1

Basically it's a bunch of technical and API notes and the last so many log entries to speed up investigations. If SAM sees warning or critical, I'd like to have the application/SAM collect the contents of https://foo.bar/1 and include it in the alert email that gets sent.

Has anyone ever done this before in SAM? Is there a module or plugin etc I should try?

It is an easier job for Web Performance Monitor (WPM) as it can capture screenshots of each step of a multi-step web transaction

You can create new SAM template with Windows Powershell Monitor and alert on its status.

Powershell script can get contents of the site, parse it and set SAM component status according to results.

Example script:

$response = Invoke-WebRequest https://thwack.solarwinds.com/# Get HTML document from response$htmlDocument = $response.ParsedHtml# Find element by ID$element = $htmlDocument.getElementById("jive-widgetframe-title_93475")# Get element text$elementText = $element.innerHTML# Check text contents of elementif ($elementText $e -like "*Trending Right Now*") {Write-Output "Statistic.Status: 0"Write-Output "Message.Status: Element contains expected text"} else {Write-Output "Statistic.Status: 1"Write-Output "Message.Status: ERROR: Element does not contain expected text"}

Note that ParsedHtml can be quite slow so you may want to parse raw HTML content instead ( $response.Content )

How would that pull the full page content over into the email alert?

I added a "HTTP Monitor" application monitor to server X. Server X just so happens to be my primary poller, but you could use any server you want. You can specify a URL, what text you want searched for, and how often it's checked. I then setup an alert to fire when the application name is equal to HTTP and it's availability is DOWN; condition must exist for more than 2 minutes. I also added a component element to the whole thing so I could include component details in the alert emails that are being sent. Screenshots are attached:

I've since removed the Status: line that was not reporting any info.

It works well. :-)
