Hi, Alex!
I use HostMonitor v.9.90.
I have 3 situation.
1. If I try use URL test from Active RMA agent
URL = http://ya.ru:80
I have Status- Host Alive

2. If I try use URL test from Active RMA agent
URL = http://ya.ru:80
with advanced flag "Check contents" and "use expression" with value
'HTTP' and '200' and 'Ok'
I have Status- Host Alive

3. If I try use URL test from Active RMA agent
URL = http://ya.ru:80
with advanced flag "Check contents" and "use expression" with value
'HTTP/1.1' and '200' and 'Ok'
I have Status - Bad contents

Please help resolve this problem with expression.

URL request does not check HTTP header contents.
It can check only HTTP page content.
Your page contains "class="i-flashcookie ", "/2000/svg" and "<head xmlns:og="http://" strings, but it does not contains "HTTP/1.1" word.

If you need to use URL request test, you may use "Use Warning Status if" option (located on "Test properties" dialog) with expression like the following:
%HTTPCode%<>200

Or, you may use HTTP test. It can check HTTP headers.

Thank's! It's working!

I have any question.
I try test HTTP on Active RMA (Windows). I set on RMA agent on field Enable the following actions - flag HTTP request.
URL=http://www.ya.ru
Request=HEADER
In Hostmonitor I have Status Unknown and Reply not implemented.
I not check while in HTTP test properties flag Check header.

I tried button Test - and recieve -
Test status:Host is alive
Error code:0.
But in Hostmon status Unknown and Reply not implemented?

I did not undestand what happend. I created another URL request and set Use Warning status if = %HTTPCode%<>200
I have Warning Message - missed operand in expression: <>200
Why? What I did bad?

If it's new ,just created test, use quotes in expression:
'%HTTPCode%'<>200

Thank's. in quoites it work!

And what I must do with HTTP test?

HTTP test may check HTTP header directly using your expression:
'HTTP/1.1' and '200' and 'Ok'
Just open "Adbanced..." settings of Test properties dialog (HTTP test), mark "Check header", select "use expression" and provide your expression. e.g.:
'HTTP/1.1' and '200' and 'Ok'

Sorry, HTTP test is not supported by RMA.

Mikevirtu · Post by **Mikevirtu** » Wed May 13, 2015 6:03 am

it is planned to make?

low priority task (there is URL test supported by RMA and usually you don't need agents for HTTP checks - this protocol opened on most firewalls)

I have problem with certificate. I use URL test and test host by IP

I use "Use Warning status if = '%HTTPCode%'<>200"
and recieve Warning.
Test working from active RMA.
I checked in Advanced
HTTP/HTTPS:Code 302 (redirect) is Ok
HTTPS:Ignore unknown certificate authority problems
HTTPS:Accept certificates with invalid host name
HTTPS:Accept certificates with invalid dates
despite this I get - Warning.
Please help me.
Thank's.
Mike

What HTTP code returned by server?
What status do you see with disabled "use warning status" option?
