Description
There's no example of how to use the "compare_string" action of JDBCQueryMonitor, so I just followed the example for "row_count". However, when using the compare mode, you need an additional parameter, "column".
Adding a short example monitor, like this, would be useful for other users:
<service name="MariaDB-Galera" interval="300000" user-defined="false" status="on"> <parameter key="retry" value="1"/> <parameter key="timeout" value="3000"/> <parameter key="driver" value="org.mariadb.jdbc.Driver"/> <parameter key="user" value="opennms"/> <parameter key="password" value="********"/> <parameter key="url" value="jdbc:mysql://OPENNMS_JDBC_HOSTNAME"/> <parameter key="query" value="SELECT VARIABLE_VALUE FROM INFORMATION_SCHEMA.GLOBAL_STATUS WHERE VARIABLE_NAME = 'wsrep_cluster_status'"/> <parameter key="column" value="VARIABLE_VALUE"/> <parameter key="action" value="compare_string"/> <parameter key="operator" value="="/> <parameter key="operand" value="Primary"/> <parameter key="message" value="Galera Node is not in primary component"/> </service>
