ACE http probe "request method type" mandatory on A3(2.6)?

Hi people,
I recently upgraded to A3(2.6) from A3(2.0) and I don't see the N/A option on the http probe "request method type".
It also has an asterisk * which means it's mandatory.
I tried to set up a new http probe for another farm I am creating and the probe shows status failed, although I can ping and telnet to the http server on port 80 from the ACE context. My probe is like that:
probe http http_probe_WWW
  interval 15
  passdetect interval 60
  expect status 200 200
  open 10
My other http probes for other farms work ok after the upgrade and they are similar.
So my question is: Do I need to set the request method type or something else causes the probe to fail?
thanks a lot.
George

What you see is a problem with the GUI.
CSCtg78008    while creating http probe default method slected should be get as in CLI
But the request-method is not required.
So your config should work.
Do a 'show probe detail' to see the failure reason.
Get a sniffer trace as well.

Gilles.

  • ACE HTTP Probe with regex

    ACE HTTP Probe with regex
    Hi,
    I'm trying to setup a HTTP probe with expected string rather then a code (config below). I do a GET for the page then a search for a string in the response however it's not working, as probe appears as failed.
    I've tested the connection to the server by using telneting and then looking at the page displayed to make sure the string I want to match is in the response.
    probe http HTTP-PROBE
    port 43050
    interval 30
    passdetect interval 30
    passdetect count 1
    request method get url /action=help
    open 43050
    expect regex action=help
    Q. Is there anything wrong with this configuration and what I'm trying to achive?
    Thanks,
    Pritesh

    Use "expect status" under probe config. expect regex doesnt work if expect status is not configured.
    expect regex work flawlessly with static pages. It doesnt work all the time with dynamic pages.
    Specially if "content-length" header is missing from Server response.
    Hope it helps

  • CSM HTTP Probes with Method GET

    Hello.
    How does the HTTP Probe with Method GET work on CSM and what is the difference with CSS?
    CSS calculates the HASH of the web page it receives as a first answer and considers that as a REFERENCE HASH, to compare with subsequent answers. Is the behaviour of the CSM the same?
    In the CSS it is also possible to insert the HASH in the configuration as a reference HASH. I did not find such a command on the CSM. Is that feature not present on CSM?
    Thanks.

    the CSM just looks for the response code.
    No hash or anything similar to the CSS.

  • Ace HTTP Probe expect regex

    Hi,
    I have a question about the config of the ACe probe.
    I have the following probe defined :
    probe http P_HTTP_TEST
    interval 5
    passdetect interval 2
    passdetect count 2
    request method get url /test
    expect status 200 200
    expect regex trululu
    I would like to use the regex just like the expect string on the csm probe...
    The regex doesn't seem to work as the strin trululu is not on the page tested.
    I guess the expect status override the regex but without the expect status it doesn't work either.
    Anyone know how exactly the probe expect works for http ?
    Another question, on the CSM module, the tcp probe by default use the real port for the probe, not the default port of the probe type, is it possible to change that so it mimmicks the CSM way of working ?
    Thanks a lot ;-)

    This seems to be bug related to some version of ACE software as HTTP return code overrides missing regexp. For sure this bug is present in:
    system:    Version A2(2.0) [build 3.0(0)A2(2.0)]
    Notice the difference between 192.168.1.1 (is missing regex in HTTP response) and 192.168.1.2 (sends regexp in HTTP response). Both are successful and as addition 192.168.1.1 (missing regexp) is showing last status code 200 which seems to be sufficient for probe to pass. 192.168.1.2 (which sends expected regexp) doesn't show last status code.

  • ACE HTTP probe hash md5 value

    Hi,
    We would like to see the hash value calculated by the ACE when the HTTP probe hash command configured.
    This is possible on CSS via the "sh service" command. We have tried to get it from sh rserver , sh probe XXX detail sh serverfarm XXX det but we do not get it.
    Is this possible to get it on the ACE as we do on the CSS?
    We need this to manually configure it via the hash <value> command because if the ACE probe is reseted for any reason, the probe http hash will be re-calculated based on the first http response of the server and we can not predict that the server will give the expected web page at this time.
    A // question is: on what the md5 value is calculated? HTTP header + payload or only http object payload? We have calculated the md5 hash value by ourselves but the probe is still failing whatever the http portion used for the calculation is.
    Many thanks for your help.

  • ACE HTTP Probe Question (HTTP Version)

    Hello, I am wondering what HTTP version ACE uses when sending HTTP/HTTPS probes to a web server. I am currently running A2(3.3) if that has any bearing. TIA

  • ACE HTTP Probe

    Hi,
    This is the current probe that I am using:
    probe http http-probe
    interval 3
    passdetect interval 3
    passdetect count 3
    request method head
    expect status 200 200
    Someone told me that I should be using a more sophisticated web page to probe. If you agree with that statement, could someone please provide a sample config?
    Thank you...

    Hi,
    I'm not sure what your colleague meant by more sophisticated. When I've set up an HTTP probe I've asked that the server management team set up a simple static page on the server that can be tested. So in my probe I'd specify something like:
    request method head url /serverhere.html
    This enables the team to take a server out of service by renaming the page (e.g. to servernothere.html) without having to ask me to modify the ACE configuration. The server can then be tested without real users having access and brought back in when they're happy.

  • ACE http Probe Question

    Hi there,
    I have a probe and it keeps failing. I believe it might be something to do with the special character in the URL. The URL requires a port then a page after the server address:
    probe http Server2_Probe
    description Checks Server2 http is responding
    ip address 10.x.x.x
    interval 30
    faildetect 4
    passdetect interval 3
    receive 5
    request method get url :8100/gdesktop
    expect status 200 200
    Can someone point me in the right direction as to how I implement this probe if the :8100 port syntax is not allowed?
    Thanks

    Hi,
    In the probe definition add
    port 8100 - this changes the port used from the default of 80. Then remove :8100 from the url.

  • Attempting to use HTTP probe

    We're currently using the TCP probe for a load balanced app, however will need to change it to HTTP. The back-end servers are Window based and are running IIS. There's an app team, another team that supports IIS and another team that support the servers. Once we've configured the HTTP probe on the ACE, including the request method and the url, which of the above team would we need to reach out to coordinate the url path and the expected status code from the server?
    Thanks.
    _ Greg...  

    Thanks Kanwal. I was just curious which team would the load balancer team be typically dealing with as in my case, it has become a hot potatoe syndrom and none of the teams is willing to own up to this task and pointing fingers to the others. It would seem to me the app team be most likely the one as the server team be just supporting the servers and the IIS team be managing the IIS.
    Thanks again.

  • HTTP Probe and DNS names

    Hi,
    I think i have a very simple question.
    I want to setup an HTTP probe to test for URL, like http://www.cnn.com/
    When I specify such "request" command under probe confif menu, I would assume that ACE will need to perform name resolution for www.cnn.com, but I cannot find any reference on how to configure DNS servers on ACE....
    Am I missing something, or maybe I cannot do HTTP probe request by name and it had to be in a format of
    http://<ip address/?
    Thank you,
    David

    Hi,
    My initial idea was to use the following command:
    request method get url http://www.abc.com/
    This is why I had my initial question about how will ACE resolve www.abc.com
    Now thinking more about it I wonder if ACE even needs to resolve it at all.
    I intend to apply the probe under rserver in serverfarm config, so ACE will know the IP address of where to send the probe from rserver configuration. If so, no DNS query is needed. ACE will just construct the packet and put relevant information in HTTP portion.... Am I correct?
    If yes, what would be a difference is doing
    header Host header-value "http://www.abc.com/"
    vs
    request method get url http://www.abc.com/
    Thanks!

  • ACE 4710 HTTP Probes

    Using the ACE 4710 for loadbalancing a Sharepoint site.
    We currently have a HTTP probe setup to check the port 80 status of the rserver.
    Is there anyway to get the HTTP probe to check a DNS entry for each of the application sites? For instance http://info vs http://site are two different web sites running on the same IP. One site could have a problem but the actual port 80 for the IP may be still alive.
    Thanks for any information.

    Has anyone figure this out?  I am tring to get healthchecks/probes setup in this same fashion.  I have 2 servers with 1 IP but have many sites.  I want to probe each side and ensure I get a 200 code.  I also have to provide credentials to the site.  It seems that if i open IE I can log in just fine to the site with the credentials.  However there is an active x control box that is wanting to be installed.  When I set this up on my ACE it seems I am getting a http 401 unauthorized error.  I have done a wireshark capture while I was browsing and I see the 401 however it also reports a 200 code after that.  Do you think this is a problem because of the active x control wanting to be downloaded?  Or is this an issue with the first http code that is recieved by the probe, that being the 401 and then the 200? Below is my config (cleaned of course).

  • ACE 4710 http probe get url question

    I am trying to create a http probe using the request method get url command. My url contains a question mark and the ACE will not accept the url as is and it strips out the question mark character. Is there a way to make the ace accept a url containg a question mark?
    probe http HTTP_PROBE
      port 9040
      interval 10
      faildetect 5
      passdetect interval 60
      expect status 200 200
      open 1
    The url I am trying to enter is /psp/epprod/?cmd=login
    When I enter it the ACE does as shown below
    (config-probe-http)# request method get url /psp/epprod/?
    <LINE>
    ACE-APP-02/vc_peoplesoft(config-probe-http)# request method get url /psp/epprod/cmd=login
    It strips out the ? character.

    Hi Nicholas,
    To enter a question mark you need to type ctrl+v prior to entering the ?
    You enter the control key then lowercase v, then your question mark.

    The obvious culprit here is the return code. How do we assign the correct return code here?
    Thanks...

    Hi,
    I wouldn't just let it default. It is better to probe for a particular page if that is possible. If this is a page you create, then it offers the possibility of being able to take a server out of rotation simply by renaming the page. E.g.
    probe http PROBE-iamhere
    interval 30
    passdetect interval 10
    request method head url /serverhere.html
    expect status 200 200
    Alternatively, it looks like you are getting a 302 response code (a redirect) then you could just change the line in the probe to expect that.
    probe http WEB_SERVERS
    expect status 302 302.

  • ACE http health probes - best practice for interval and passdetect interval?

    Hi,
    Is there a recommended standard for http health probes in terms of interval and passdetect interval timings, i.e. should the passdetect interval always be less than the interval or visa versa? Can a http probe be 'mis-configured', i.e. return a 'false positive' by configuring an interval timeout thats 'incompatible' with the device it's polling?
    I have a http probe for a serverfarm consisting of two Apache http servers and get intermittent 'server reply timeout' probe failures. I'm keen to ensure that the configuration of the probe isn't at fault so I can be confident that a failed probe indicates a problem with the server and not my configuration.
    The probe is currently configured as below:-
    probe http http-apache
      interval 30
      passdetect interval 15
      passdetect count 6
      request method get url /cs/images/ACE.html
      expect status 200 304
    Any advice on the subject woud be gratefully received.
    thanks
    Matthew

    Hi Gilles,
    Thanks for the advice. In another dicussion (found here https://supportforums.cisco.com/message/462397#462397) a poster has stated that:-
    "(The) "Probe interval" should always be less then (open+recieve) timeout  value. Default open & receive timeouts are 10 seconds."
    Are you able to advise on whether the above is correct and if so, why? I currently have an interval value of 30 that obviously goes against the advice above (which I've interpretted to mean that if you leave the open & receive timeouts at their default settings your probe interval should be less than 20 seconds?).
    thanks
    Matthew
