Load Balancing Health Checks

I am looking for per-protocol health checks to work with a Netscaler load balancer for Exchange 2010. I have the one for OWA working (see below), but I cannot seem to find anything else on the other protocols (ECP, EWS, OAB, AS, etc.). Does anyone have this
information? Citrix website is less then helpful.
OWA health check:
Custom header: Agent: Mozilla/4.0\r\nHost: FQDN\r\n
Send String: GET /owa/auth/logon.aspx?url=https://FQDN/owa/&reason=0
Receive String: Outlook

Load Balancing Health Check Probes

Are these values correct for setting up a load balancer with Exchange 2013 Layer 7? Trying to go over this article from Ross Smith:

Easy enough to check. Paste each into a browser. If you get a 200 response ( assuming the health probes are active), then you know you are using the correct URLs.
If you are using 2013 SP1 and have MAPI/HTTP enabled it would be https://mail.company.com/mapi/healthcheck.htm

How can I support a health check, from a load balancer?

My company has load balancers which use health checks to determine if the end point is available for client traffic. The basic health check is a tcp ping, and will tell you if the device is on the network. The next level of health check is an http request. This request, and the response are static, you can’t create your own version of the request and response. The standard request is this:
     http://host:port/healthcheck/hc.html
The standard response is this:
     “The server is available”
I want to use the load balancer as part of my total deployment. The problem is that I am not seeing how to support this health check request and response in the MDEX engine. What I see is this request
     http://host:port/admin?op=ping
Will return this response
     dgraph <host>: <port> responding at <day month year time>
It is nice that there is a built in ping, but I am not able to make use of it. I am new to Endeca and still poking around. The dgraph process listens on a port set up in <…>/config/script/AppContext.xml
<dgraph id="Dgraph1" host-id="MDEXHost" port="3281">
<properties>
<property name="restartGroup" value="A" />
<property name="updateGroup" value="a" />
</properties>
<log-dir>./logs/dgraphs/Dgraph1</log-dir>
<input-dir>./data/dgraphs/Dgraph1/dgraph_input</input-dir>
<update-dir>./data/dgraphs/Dgraph1/dgraph_input/updates</update-dir>
</dgraph>
(I am not using the default port, as I only have an instance on a shared server and have to worry about port clashing. But that is a different thread.)
In a standard tc Server install I can support this health check by doing this:
* Create a directory named “healthcheck”, in the “webapps” directory.
* Place a file name “hc.html” in that directory, which contains “The server is available”
The one hack which comes to mind is to write a servlet which would be able to be a smart proxy for the load balancer health check. It would pass along any regular traffic to the MDEX engine. But if the request was a health check it would send “admin?op=ping” to the MDEX engine, and for a good response from the engine, create and pass back the correct response to the load balancer.
Ideas, comments, flames, …
Thanks

Hi, we are using following String to test the MDEX ping response but we get the invalid version formation on dgraph.log -
following is on F5
GET /admin?op=ping HTTP/1.1/r/nHost:myhost.endeca.com:19000/r/nConnection:close/r/n/r/n
Following gets logged on Dgraph.log
WARN 09/05/12 05:30:03.799 UTC (1346823003799) DGRAPH {dgraph} Invalid version format in 'HTTP/1.1/r/nHost:myhost.endeca.com:19000/r/nConnection:close/r/n/r/n'
Please let me know - if you have any suggestions to solve this issue.
I know that it works from browser and wget from unix with following commands.
wget http://myhost.endeca.com:19000/admin?op=ping - from unix command line
from browser:
http://myhost.endeca.com:19000/admin?op=ping

Health check for load balancing ALSB/OSB instances

What is the standard practice for a load balancer sitting in front of ALSB/OSB instances as far as a health check? I'm working with our IS department to implement a valid health check. Currently the load balancer (older model cisco device) is just checking for an active port which is generating excessive logging on the ALSB side. As a workaround I'm just going to have the loadbalancer check for a http 200 response and a greater than zero body size.
thanks in advance...

it depends on the type of load balancer what it can do. I suggest create a 'empty' proxy service that does not have logging or auditing. Publish the prox and use this webservice in your load balancer to check if the service is available.

Load Balancing Financials

Hey,
Can anyone tell me what HTTP GET request they are using in their Load Balancer to check if Financials is working correctly so as to direct clients to a working server?
I was thinking:
GET /OA_HTML/RF.jsp?function_id=28804&resp_id=-1&resp_appl_id=-1&security_group_id=0&lang_code=US&params=
When I am redirected by the server I get params= and then a long alpha numeric string which seems to change for each server, anyone know why?
Cheers

Load balance data files

Hi,
I have heterogeneous sources (txt,foxpro,ora tables etc) to be loaded to SQL Server, which I've SSIS pkg working fine to load these data sources . I need to do a load balance to check the records in the file to compare it with loaded rec in sqlserver tables.
Please guide me with the logic to start with, also if there are any generic code available which can be edited to use for load balancing.
Thanks
Neil

Thanks Ernest,
I have a business requirement to fail the pkg at error. Hence I need to count the rows from the source file itself, is this possible, or will have significant impact on performance.
Hi Neil,
I would suggest you post the detail error message and elaborate it with more detail. As Ernest's suggest above, we can use "Row Count transformation" which counts rows as they pass through a data flow and stores the final count in a variable.
For detail information, please refer to the articles below:

Health based load balancing.

I know that RM can provide health based load balancing e.g. RM will stop giving the load if WEF server is not healthy. We have a F5 load balancer, Can't we get the health based load balancing using F5?
Regards Restless Spirit

i think you can do. You can specify the number of monitors that must report a pool member as being available before that member is defined as being in an up state.
check this support article will give you different method of loadbalacing

CSS load balancing, service dependancy condition check

Hi,
I would like to seek some advice regarding the CSS's service configuration.
Is there a way to configure the CSS such that it check for the condition/status of a independant service (not involved in the load balancing algorithm) is alive/down (using service mode keepalive port/type), before deciding whether to/not to load balance to a group of services?
Senario is as follwows:
We process incoming HTTPS request and load balance to 2 HTTPS Servers (HTTPS service SSL1 and SSL2), on condition that a independent service (HTTPS service SSL3) is alive (using the keepalive type/port check in service mode).
If the independant service (HTTPS service SSL3) is not alive, remove the HTTPS Servers (HTTPS service SSL1 and SSL2) from the load balancing algorithm.
Thanks in advance for assistance

Forms Services availability checking for BIGIP Load Balancer

We are load balancing across a number of 10.1.2.2 Forms servers using a BIGIP load balancer. Currently our load balancing is done based on which server has the "least connections" to the BIGIP. So far we have been using the following test URL to allow BIGIP to check the availability of the Forms Services on each server.
http://server:port/forms/frmservlet?ifcmd=status
This works well however it only checks through to the HTTP level within Forms Services. We encountered a problem when the Forms Services failed to work on a particular server however the above URL showed that everything was OK. The effect of this was that all new users attempting to login were directed to the failed server as this server had the "least number of connections".
After raising an SR with Oracle they advised that the forking of runtime processes had probably failed and this was not detectable by the load balancer with the above URL. So they have recommended a number of options for checking the status of the Forms Services. These are:
a) http://server:port/forms/frmservlet
This loads the default Form and therefore by definition tests the forking of runtime processes. However BIGIP is unable to automatically process the information to distinguish whether the service is up or down. Oracle recommended that if using this method we would need to customise BIGIP to handle the various FRM-xxxx error codes.
b) http://server:port/forms/frmservlet?userid=scott/tiger@YOURDB&form=yourtestform.
fmx
Even more thorough would be to actual log on to the database using a test form as above.
My question is does anyone out there have experience in checking Forms Services availability using these last two methods as I'm not sure how to customize the load balancer so that it can handle the output of these URLs. Also when using the original URL is it normal to load balance using a "least connections" method or do people out there use a different algorithm.
Thanks for any help/advise that you can give.
Regards,
Philippe

Well SR followed up and it looks like the only course of action is to use the standard HTTP check: http://server:port/forms/frmservlet?ifcmd=status ...
... unless that is you want to do some serious customisation. Oracle don't support any other form of checking.
I'm guessing from the lack of responses to this thread that this hasn't been an issue for anybody else ... ???
Any thoughts/suggestions really welcome as we go into production in 4 weeks.
a) What do people recommend for load balancing Forms ... least connection, round robin ... ?
b) Do people use http://server:port/forms/frmservlet?ifcmd=status or have some of you used something else?
Thanks,
Philippe

Checking number of connection in load balancer

Hi,
could you help me find how many connection connected to load balancer in avg and peak connection on daily basis.
any script or tool to help us find out how many connection hitting to live real servers and VIP,

Hello,
You can utilize ACE Device Manger which is a built-in GUI tool to monitor system statistics. It is bundled in any license.
It is pretty easy to start. You need only basic configurations to access management address via https, and
snmp community for monitoring.
# Monitoring a rserver
You can change time range to view the graph. Options are 1h, 2h, 4h, 8, 24h, or All Date.
On the ACE, statistics are kept for 7 days or 20,000 hourly records, whichever comes first.
# Monitoring L7 connection
I think grapsh for L7 connections are aggregate statistics of all L7 policies.
Row data view.You can download the data in Excel format.
You can find more detail about the Device Manager in the Configuration Guide.
Some sample shots of DM view are also on the configuration guide.

How to use the Load Balancer Plug-in to serve multiple domains

In SJSAS8.1 SE/EE the asadmin commands that create and maintain a load balancer configuration operate within a domain. When the load balancer configuration is exported an xml file is created that contains all the information for that domain. To make the load balancer plug-in balance the load for multiple domains, the loadbalancer.xml files can be manually merged to conatin the data that is exported from each domain's load balancer configuration.
For example, 2 domains are created, both having a load balancing configuration. After exporting both configurations using the asadmin export-http-lb-config command, the user would then cut and past the cluster information into the single loadbalancer.xml file that resides under the web server's config directory.
An example of the manually merged loadbalancer.xml file follows:
<?xml version="1.0" encoding="UTF-8"?>
<loadbalancer>
<cluster name="domain1">
<instance disable-timeout-in-minutes="30" enabled="true" listeners="http://localhost:1026 https://localhost:38181" name="i1"/>
<instance disable-timeout-in-minutes="30" enabled="true" listeners="http://localhost:1027 https://localhost:38182" name="i2"/>
