NimbostratusMonitor app port plus 1
I want to create a generic tcp monitor that I can put on any pool, and it will monitor the application port plus 1.
For example - if the application is running on port 3000, I want this monitor to watch port 3001.
Is there any way to do that without creating a tcp/3001 probe?

You could create an external monitor to make a request to the pool member port plus one, but I think it would be a lot of unnecessary resource overhead compared with manually creating a built in monitor for each new port.
Aaron- I would have to agree with hoolio. Even with the simplest netcat monitor, the additional overhead of an external monitor would most likely be excessive if you are monitoring a large number of servers in this manner, and if the number of servers is small, it is relatively straightforward to configure and manage a set of monitors with a port alias.

sojourner9_8636It isn't a huge number of servers, but a number of pools, and growing, each pool with its own port. So, I've created a "tcp_3001" monitor for the tcp/3000 pool, a "tcp_3011" monitor for the tcp/3010 pool, etc. Probably about 20 pools like that right now with possibly more down the road.
Not a huge deal. But, I would have preferred to use a common probe/rule if it could have been done easily.
