Monitor a webpage change with ossec (or other if motivated)

The need:

to monitor a webpage & send an email each time it does not display the expected string.

I want it implemented using ossec's custom rules.

because ossec is already installed & configured for email alerts.

normal string is like:

API keyword V1

In case the server is down or it cannot access database it returns something different, like this:



<title>503 Service Unavailable</title>


<h1>Service Unavailable</h1>

<p>The server is temporarily unable to service your

request due to maintenance downtime or capacity

problems. Please try again later.</p>


<address>Apache/[url removed, login to view] (Debian) Server at [url removed, login to view] Port 443</address>


I propose to set a cron task that do:

curl -o /tmp/frontalive [url removed, login to view]

the game is not to set the ossec custom rule to detect changes on /tmp/frontalive so that it triggers an email when it is not equal to "API keyword V1"

see Create Custom decoder and rules — OSSEC 2.8.1 documentation
