HTTP Health Monitor Receive String issue
I am currently having an issue with the Receive string part or a HTTP health monitor. I am using a GET request like: GET /default.aspx HTTP/1.1\r\nHost: myurl.com\r\n I am also using authentication which seems to work fine. What i want is to check the HTML for something like 'hello' within the title/body or whatever. The monitor works as when i input 200 ok - the pool appears as up. Also, the Receieve String does not. Does anyone have a working example of a receive string that looks for a match within the body rather than just the Header or simple HTML tags? Thanks
Help with SOAP Monitor
I am attempting to use the built-in SOAP monitor on an LTM with 10.2.4. I have made several attempts, but no success yet. Any help or advice would be much appreciated! One of the biggest issues I have is how to I validate that the customer has given me a legitimate POST request and that I'm getting back the result they say I should? They claim to have verified using SOAP-UI, and tell me that this request should work but so far my pool members all fail this monitor. Admittedly, I have very little SOAP knowledge and so I'm having trouble deconstructing the SOAP POST request the customer has provided me, with what I need to put in the fields of the monitor. Can someone help me identify what components of this request need to be included in my SOAP monitor fields and what goes where?
Can I change the default ephemeral ports that the F5 uses for health monitoring?
Currently I see that my F5 is reaching out to the servers in my server pools on low ephemeral ports for health monitoring. For example, I have a health monitor for DNS so that the F5 reaches out to the DNS servers to ensure that DNS is working properly. The source port coming from the F5 has a huge range from sometimes 7000 up to 65535. We are trying to standardize the ephemeral ports used in our datacenter to use the standard Microsoft ephemeral ports, 49152 - 65535 for ACI filtering. Can I manually change which ports the F5 uses to send requests on? I know we are currently doing this with Linux servers, so I'd like to do it with the F5s as well.GTM health monitor fails on pool, but not on member.
I am running GTM 11.4.1 HF1. If I assign the default HTTP health monitor to a GTM pool, the pool goes red. If I remove the pool health check and add the HTTP health monitor to the member that's in the pool, the pool goes green. The GTM has no problem making a telnet connection on port 80 to the member. It can ping and tracert to the member without problem. This behavior happens for any pool and member combination. Is this expected behavior? Why can I not set a pool health check and have it work correctly? I spend most of my time in LTM and am accustomed to LTM behavior. thanks!Assign HTTP monitor to a Node and not Pool
Hi, I have been looking to see if it's possible to assign a HTTP monitor to an individual Node. From what i gather, only basic monitors can be applied (like those without a defined receive string). Is there anyway around this? Scenario: 3 servers in a pool and we want to be able to do a get request to those specific servers and individually take them offline based on the response. Thanks,Health monitor that reads the contents of a text file
What i want is a Health monitor that essentially reads the contents of a text file. For example: If the contents of the file is '1', this will indicate the node is down and another pool member will be used. The idea is that we can manually change the file contents to indicate when we want a node taken down without going onto the F5. Any help is appreciated. Thanks
External Monitor for Pool
Hello, I have a two-node pool containing servers that are mirrored search servers. These run the Coveo search service (CES Mirror Service). I'm trying to determine the appropriate monitor to effectively load balance these servers. I'm thinking perhaps we need an external monitor that would monitor this CES Mirror Service. The servers run some other Coveo processes as well, but I'm not sure (yet) which would be best to monitor. So, my question, how do I write an external monitor? Alternatively, if a built-in monitor would work, I'd like to hear which I should use. I'm an IT Ops person, not programmer/developer, so I don't understand scripting. Thanks in advance. Happy Holidays! Diane
