this source code project for an example COM based Servers Alive check.
External Check Samples (errorlevel based)
Used for errorlevel based checks.
SMTP2POP3 -
We suggest to use the COM version which can be found on this same page
SMTP2POP3 sends an email using SMTP to a mail server, and then attempts to collect that same email through POP3 from a server (not necessarily the same server), thus verifying more completely the functioning of the mail server.
v1.0.0.20 - 14-OCT-2003
Count Files -
We suggest to use the COM version which can be found on this same page
Let's say you have a mailserver that uses a spool directory. If the mail server is running correctly, it should deliver the mail within 5 minutes to the internet. But since sometimes the mail service runs, and still the mail server isn't running correctly, it's not enough to check the mail server service. It would be nice to be able to check the number of files in the mail server's spooldirectory and have Servers Alive warn you when more the 200 files are in that directory.
By using a combination of the external check of Servers and COUNTFILES.EXE it's now possible.
ODBC Check -
We suggest to use the COM version which can be found on this same page
Verify an ODBC connection. Just opens and closes a connection.
Event ID Check -  (written by Mark Bradshaw)
Check for specific event IDs and conditions on NT computers. You will need a perl interpreter.
WINS Check -
Verify if your WINS server resolves names correctly.
DB2 Check -  (written by Jason C. Stone)
Checks if a DB2 server is running or not. Uses the DB2 client.

Extra Tools
Some "nice to haves" that serves to make life easier.
Sangfroid Jr. (and templates) -
(written by Brent Ozar)
Sangfroid Jr., check your ServersAlive logs over the web, get drill-down detailed history of an individual check, and more.
Also a great resource for some nice Servers Alive templates.
SAAim -  (written by Mark Bradshaw)
SAAim is a free utility that allows you to send alerts to yourself via AOL Instant Messenger. Get details and documentation at http://www.networksimplicity.com/utils.
SARemote -  (written by Mark Bradshaw)
SARemote allows you to easily monitor the overall status of your Servers Alive installation from a remote machine. SARemote is a Visual Basic application (includes source). Get details and documentation at http://www.networksimplicity.com/utils.
Alternative mailers
Use the other mail option of Servers Alive if our built-in SMTP mailer doesn't fit your needs.
Exchange/MS-Mail -
Syntax:
mapisend -u "ProfileName" -p "" -r touser -s "subject" -m "%m"
SMTP -
Some people want a fixed subject (to send to some kind of pager service) and this can NOT be done with the Servers Alive native SMTP mail send.
Syntax:
postie -host:host_name -port:smtp -to:touser -from:fromuser -s:"subject" -msg:"%m"
