Controlling the Addition of Events to SAE Fail Queue (SRC CLI)

Whenever SAE fails to restore the connection to the SRC VTA, events are added to the SAE fail queue of the SRC VTA. The addition of events to the SAE fail queue increases the fail queue size and leads to consume a substantial amount of disk space in the memory partition.

The SAE polls the fail queue size at regular interval (every 90 seconds) and checks the free space in the disk. If the free disk space is less than the configured minimum free disk space value, the SAE stops adding the events to the fail queue. You can use the min-free-diskspace-percentage option under the [edit shared sae group group-name configuration plug-ins vta-failqueue-size-config] hierarchy level to configure the minimum free disk space required to add the events in the fail queue.

Use the following statements to configure the minimum free disk space required for adding the events in the fail queue:

shared sae group group-name configuration plug-ins vta failqueue-size-config {min-free-diskspace-percentage min-free-diskspace-percentage}

Note: You must set the CLI editing level to expert by using the set cli level expert command for this configuration.

To control the SAE from adding events to the fail queue:

  1. From configuration mode, access the configuration statement that controls the SAE from adding events to the fail queue.
    [edit shared sae group group-name configuration plug-ins]user@host# edit vta-failqueue-size-config
  2. Enter the minimum free disk space in percentage. The value ranges between 10 and 100. By default, the value is set to 20.
    [edit shared sae group group-name configuration plug-ins vta-failqueue-size-config]user@host# set min-free-diskspace-percentage min-free-diskspace-percentage

    Note: We recommend that you configure an appropriate value for the min-free-diskspace-percentage option, because configuring a very high value leads to considerable drop in the events getting added to the fail queue.

  3. (Optional) Verify your configuration.
    [edit shared sae group group-name configuration plug-ins vta-failqueue-size-config]user@host# showmin-free-diskspace-percentage 15;
