Monitoring and sharing data among server groups

Each server in a server group of a data center can run a data collection agent. The agent can collect data from a respective server in the server group. The data can include a performance characteristic (i.e., performance data) associated with the respective server. If the performance characteristic falls outside an allowable range, the agent can broadcast this information to other agents at other servers in the server group. If the other agents at the other servers in the server group detect a similar performance characteristic outside the allowable range, they can broadcast as well. If there is a sufficiently high quantity of broadcasts, then that can indicate a high likelihood that there is a potential problem with respect to servers in the server group. The problem can be reported to the central controller, which can then handle the problem appropriately (e.g., issue an alarm, contact support technician, etc.).
