Converting Cisco CSS "Monitor" to F5 iRule

Hi,

 

 

I use the CSS as well, but the Big IP can do things a little more intellgently. Is the reason you are using the hash value because you change something in the text file? If it is, you could use an http monitor and check for a word within the file. If its not there, the service is marked as down. This is good for dynamic monitoring of backend systems to make sure the webserver can pull a query from a backend server.

 

 

So, if you create a new http monitor, you need to add the following:

 

 

send string - GET /admin/status.txt

 

receive string -

 

Alias service port - 2080

 

 

Hope this helps!
