Hi,
I have created a health monitor with the following config:
Interval 5
Timeout 16
Send String GET /test/test.jsp
Receive String HTTP 1\.(0|1) 200
Reverse No
Transparent No
Alias address ALL
Alias Service Port ALL
But whne I go to add it to a specific node choosing NODE SPECIFIC I cannot see the monitor I created inside the list.
Do I need to do anything else to make the monitor a node specific one?
Thanks.
A node is an IP address whereas a pool member is an IP address and port (with an association to the pool name). Normally, you create a monitor for a pool member without an alias IP or port and the monitor inherits the pool member IP and port. A service level monitor without a hardcoded port can't be associated with a node as there isn't a way for the monitoring daemon to know what port to perform the check on. If you create a monitor with a hardcoded alias port, then you can apply it to a node (an IP address).
The short answer is that you generally want to associate service monitors with a pool. If you need to create dependencies between multiple ports or multiple IP:ports you can use the alias IP and/or port definitions on the monitor to do so.
Hope this is clear? If not, can you describe what you're trying to implement in more detail?
Hi absolutely it is clear now.
I have managed to add the monitor to the pool I have created.
Though I have another problem.
As the send string I have placed
GET /test/index.jsp /HTTP1.1\n Host:\nConnection: Closed\n
The url / test/index.jsp basicly returns a web page with words "Data and Retailer", A box and a send button.
What should I add as the receive string?
I have tried adding
Data
HTTP/(1.0|1.1) (200 OK|304 Not Modified)
which didnt succeed.
P.S. this is a tomcat app that Im trying to monitor. When the app stops the page still exists but gives a 404 error.
Hi,
I have added them. Although I have the tomcat working and application stopped the monitor still shows the node as active.
The output of the command from my workstation is:
HTTP/1.1 505 Versi�n de HTTP No Soportada
Server: Apache-Coyote/1.1
Date: Fri, 18 Jun 2010 08:09:18 GMT
Connection: close
Just a sidenote on the command. As it is tomcat I am using 8080:
echo -e "GET /test/test.jsp /HTTP1.1\r\n Host:\r\nConnection: Close\r\n\r\n" | nc ipoftheserver 8080
Hi Aaron,
I have added the following as the send string
GET /test/index.jsp /HTTP 1.1\r\n Host:\r\nConnection: Close
Although the app is up it shows as offline.
Somthing has changed,
When the application is online I get the following:
HTTP/1.1 400 Petici�n incorrecta
Server: Apache-Coyote/1.1
Date: Fri, 18 Jun 2010 09:53:59 GMT
Connection: close
And when I stop the application that is /test/test.jsp does not exist. It still gives the same error.
It would be ideal to find a page which exists in the application that you can request and receive a 2xx or 3xx response for. You can then use the receive string you have listed to check for the service status.
Also, the receive string shouldn't have any \r\n's on the end as bigd appends two for you in 9.4.x.
Personally I'm with a problem like this, I have an application that said www.teste.com / apex.apex.jnlp, escrica This application is in java, suppose one of the servers lodged during a problem with java (application) with I I can get this machine in the pool?
