Configuration Options

For the list and description of configuration options that can be set for Aodh in order to set up the services please see the Telemetry section in the OpenStack Manuals Configuration Reference.

HBase

This storage implementation uses Thrift HBase interface. The default Thrift connection settings should be changed to support using ConnectionPool in HBase. To ensure proper configuration, please add the following lines to the hbase-site.xml configuration file:

<property>
  <name>hbase.thrift.minWorkerThreads</name>
  <value>200</value>
</property>

For pure development purposes, you can use HBase from Apache or some other vendor like Cloudera or Hortonworks. To verify your installation, you can use the list command in HBase shell, to list the tables in your HBase server, as follows:

$ ${HBASE_HOME}/bin/hbase shell

hbase> list

Note

This driver has been tested against HBase 0.94.2/CDH 4.2.0, HBase 0.94.4/HDP 1.2, HBase 0.94.18/Apache, HBase 0.94.5/Apache, HBase 0.96.2/Apache and HBase 0.98.0/Apache. Versions earlier than 0.92.1 are not supported due to feature incompatibility.

To find out more about supported storage backends please take a look on the install/manual/ guide.

Note

If you are changing the configuration on the fly to use HBase, as a storage backend, you will need to restart the Aodh services that use the database to allow the changes to take affect, i.e. the collector and API services.
