Indeed all NT related checks (diskspace/service/process/perfmon) will act
differently when running as service or as application, and this due to the
authentication.  Also the fact that a real users is logged on localy to the
system and have active connection will also influence the checking.  Not due
to Servers Alive but due to how the OS reacts to that.  Most of the time the
logfile will show an errorcode and this will explain the WHY of the problem.

As for the URL checks, you're right about the proxy and the authentication.
The caching of the proxy can also be an issue.  Within the request send by
Servers Alive towards the remote webserver (via proxy or not) we request not
to use caching.  Unfortunatly not all proxy's are reacting correctly to this
request and just ignore that request.

Hi David,

Just a couple of thoughts on this... They might not help!

Testing NT services in my experience can be a bit hit or miss, depending on
the service in question. I tried checking the apache service, but it would
frequently fail to serve pages without actually stopping the service.

As for URL checks, make sure your connection is not going through a proxy
server or anything else that might cache pages.

I've always found that SA itself is consistent - the only real difference
between running as a service or interactively is the "user" SA is actually
logged on as. Things that happen differently when SA is running as a service
are usually because of the rights or settings for the respective "user".

Cheers,

Phil.

Further to my last.

We have two SA's running, one on a remote server and one locally. The local
machine does URL checks whilst the server machine installation performs
service checks. Neither machine detected this stoppage we had which lasted
at least 8 hours. Both running as a service only when run manually did they
detect the failure. Why?

Also, the logging to SQL data is now recording NULLS in all fields except
'host'.

Why is SA unreliable? We have found that SA doesn't perform checks reliably
when running as a servive. We had the w3svc service stop this morning and SA
didn't perform an IIS restart as part of its routine. However, when SA is
launched after logging on then it restarted the service correctly. We've had
this happen quite a few times and we feel that SA isn't the tool for the job
if we can't rely on it.
