Understanding ZooKeeper Configurations
ZooKeeper configurations should be stored on disk in the following structure starting at
$METRON_HOME/bin/zk_load_configs.sh
:
- global.json
The global config
- sensors
The subdirectory containing the sensor enrichment configuration JSON (for example,
snort.json
orbro.json
By default, the sensors directory as deployed by the Ansible infrastructure is located at
$METRON_HOME/config/zookeeper
.
Although the configurations are stored on disk, they must be loaded into ZooKeeper to be
used. You can use the utility program $METRON_HOME/bin/zk_load_config.sh
to load
configurations into ZooKeeper.
-f,--force
Force operation
-h,--help
Generate Help screen
-i,--input_dir <DIR>
The input directory containing the configuration files named, for example
$source.json
-m,--mode <MODE>
The mode of operation: DUMP, PULL, PUSH
-o,--output_dir <DIR>
The output directory that stores the JSON configuration from ZooKeeper
-z,--zk_quorum <host:port,[host:port]*>
The ZooKeeper Quorum URL (zk1:port,zk2:port,...)
See the following list for examples of usage:
To dump the existing configs from ZooKeeper on the single-ode vagrant machine:
$METRON_HOME/bin/zk_load_configs.sh -z node1:2181 -m DUMP
To push the configs into ZooKeeper on the single-node vagrant machine:
$METRON_HOME/bin/zk_load_configs.sh -z node1:2181 -m PUSH -i $METRON_HOME/config/zookeeper
To pull the configs from ZooKeeper to the single-node vagrant machine disk:
$METRON_HOME/bin/zk_load_configs.sh -z node1:2181 -m PULL -o $METRON_HOME/config/zookeeper -f
