Backing up Your Configuration
The HCP upgrade uses the default configuration for the new Metron version. If you made any changes to the Metron configuration in the previous version, you need to back up your old configuration so you can incorporate those changes into the new Metron configuration. You will also need to re-enter values for the Metron properties in Ambari.
Create a backup directory.
mkdir /$HCP_BACKUP_DIRECTORY
Back up your configuration information in ZooKeeper to your backup directory:
${METRON_HOME}/bin/zk_load_configs.sh -m DUMP -z $ZOOKEEPER > /$HCP_BACKUP_DIRECTORY/$BACKUP_CONFIG.txt
Back up the following property files in the
$METRON_HOME/config
directory to your backup directory:elasticsearch.properties
enrichment.properties
pcap.properties
profiler properties
For example:
cp elasticsearch.properties /$HCP_BACKUP/elasticsearch.properties
Copy the zookeeper directory to your backup directory:
cp -R zookeeper/ /$HCP_BACKUP/zookeeper
Back up your Metron configuration.
The easiest way to do this is to take a screenshot of each of the Metron configuration pages that you modified in Ambari. At a minimum, take a screen shot of the following configuration pages:
Index Settings
Parsers
