Excluding stressed machines from load balancing of distributed applications

A non-transitory machine readable medium of a particular host computer that executes at least one particular end machine of a plurality of end machines operating on at least two host computers including the particular host computer for executing a distributed application, the non-transitory machine readable medium storing a program that when executed by at least one processor redirects new network connection requests sent to the particular end machine, the program comprising sets of instructions for:

• at a monitor executing on the particular host computer:
• receiving at least one measurement data value for at least one particular resource consumed by a component of the distributed application executing on the particular end machine;
• determining whether the measurement data value received for the particular resource has exceeded a threshold amount;
• and
• when the measurement data value has exceeded the threshold amount, sending a notification message to a measurement monitoring module executing on the particular host computer to add the particular end machine to a stressed security group, members of which should not receive new network connection requests to the distributed application,
• wherein the measurement monitoring module tags the particular end machine as a member of the stressed security group,
• wherein a load balancer that balances new requests for connection to the distributed application between the plurality of end machines that implement the distributed application receives a notification message based on the tagging of the particular end machine as a member of the stressed security group, said notification message causing the load balancer not to send any new connection request from remote clients to the particular end machine.
