LSF_PROXYD_HEARTBEAT_INTERVAL

The rate limiter is available as of Fix Pack 14. You can set the LSF_PROXYD_HEARTBEAT_INTERVAL parameter for use with the rate limiter.

Syntax

LSF_PROXYD_HEARTBEAT_INTERVAL=time_in_seconds

Description

The rate limiter is managed by the lsfproxyd daemon, which monitors and controls the number of requests and connections that can reach the mbatchd daemon, protecting it from excess requests. The lsfproxyd requires interaction with the mbatchd daemon and sends a heartbeat message to the mbatchd daemon to monitor this connection.

The LSF_PROXYD_HEARTBEAT_INTERVAL parameter sets the frequency that the LSF rate limiter (lsfproxyd) daemon sends a heartbeat message to the mbatchd daemon, to indicate that the rate limiter is enabled and running. If the mbatchd daemon has not receive a heartbeat within the specified interval defined for the LSF_PROXYD_HEARTBEAT_INTERVAL value, the mbatchd daemon will assume the rate limiter is not alive and closes the channel.

As optimal performance, do not define this interval to a very small value; setting 20 and 30 seconds is optimal.

For configuration to this parameter to take effect, restart LIM by running lsadmin limrestart and restart the mbatch daemon by running badmin mbdrestart.

Running the lsadmin showconf command displays the values for the LSF_PROXYD_HOSTS and LSF_PROXYD_PORT parameters, if set. Running the badmin showconf command displays the values for the LSF_PROXYD_HOSTS, LSF_PROXYD_PORT, LSF_PROXYD_HEARTBEAT_INTERVAL, and LSF_PROXYD_BYPASS values, if set.

Valid values

Any positive integer.

Default

30 seconds

Example

LSF_PROXYD_HEARTBEAT_INTERVAL=25
