Notification of CSS Keepalive Failure

Anyone have a scripted keepalive handy to help with having a CSS 11503 monitor an ASPX page and then notify a server administrator if the page becomes unavailable? Here's my sample service config:

<br />

<br />service aspx-server

<br /> ip addr 1.1.1.1

<br /> keepalive type http

<br /> keepalive uri “/serverpage.aspx”

<br /> keepalive method head (default)

<br /> active

<br />

<br />I've previously used the global command “logging sendmail (recipient ip addr) (mail server ip addr) (level of notification to receive)”, but I'd like to have this notification be more surgical in its delivery to a user/group mailbox, not a destination ip address.

<br />

Re: Notification of CSS Keepalive Failure

I have done this - although recently it has started to misbehave slightly. In sniffing, it looks like OCCASIONALLY the CSS "forgets" to send the request, and then sends directed E-mail messages indicating a service is down because it didn't see the reply (which it isn't...).

service val-srv1

ip address 192.168.1.99

keepalive frequency 255

keepalive retryperiod 255

keepalive type script valsrv1-kal "valsrv1 http://valsrv1/test/healthcheck.asp"

active
