NimbostratusThanks Kevin. I more interested in handling capacity issues. I was thinking whether we can include code need to take care of this. Is the below doable using a probe file?
1. Send a GET request to F5- API (iControl?) and get the information for current member status information. This information can be used to find out the ratio of online/total number machines.
2. The probe based on a synthetic transaction finds that a particular server is returning 500 error.
3. Based on the http status code 500, load balancer decides to take the fauly server offline.It needs to check how many servers are online at that time, the number of servers or percentage could be hard-coded like 50%.
4. The load balancer marks the faulty server offline and will also send an alert that not enough number of servers are online in case the percentage goes below 50%.
