Package: base/frameworks/cluster
|
|
================================
|
|
|
|
The cluster framework provides for establishing and controlling a cluster
|
|
of Zeek instances.

:doc:`/scripts/base/frameworks/cluster/main.zeek`
|
|
|
|
A framework for establishing and controlling a cluster of Zeek instances.
|
|
In order to use the cluster framework, a script named
|
|
``cluster-layout.zeek`` must exist somewhere in Zeek's script search path
|
|
which has a cluster definition of the :zeek:id:`Cluster::nodes` variable.
|
|
The ``CLUSTER_NODE`` environment variable or :zeek:id:`Cluster::node`
|
|
must also be sent and the cluster framework loaded as a package like
|
|
``@load base/frameworks/cluster``.
|
|
|
|
.. warning::
|
|
|
|
The file ``cluster-layout.zeek`` should only contain the definition
|
|
of :zeek:id:`Cluster::nodes`. Specifically, avoid loading other Zeek
|
|
scripts or using :zeek:see:`redef` for anything but :zeek:id:`Cluster::nodes`.
|
|
|
|
Due to ``cluster-layout.zeek`` being loaded very early, it is easy to
|
|
introduce circular loading issues.
|
|
|
|
:doc:`/scripts/base/frameworks/cluster/pools.zeek`
|
|
|
|
Defines an interface for managing pools of cluster nodes. Pools are
|
|
a useful way to distribute work or data among nodes within a cluster.
