Configure Data Collector When the Data Aggregator IP Address Changes

To allow a Data Collector to communicate with a Data Aggregator, configure the Data Collector when you change the IP of the Data Aggregator.

Note: If the Data Collector uses the hostname, it is only necessary to restart the Data Collector to keep the communication between the Data Collector and the Data Aggregator. Configure the Data Collector only if it uses an IP address to communicate with the Data Aggregator.

Follow these steps:

1. Stop the Data Collector, if it is running. Open a command prompt and type the following command:

   /etc/init.d/dcmd stop
   

2. Edit the hostname or address in the following file:

   /opt/IMDataCollector/apache-karaf-2.3.0/etc/com.ca.im.dm.core.collector.cfg
   

   Edit the following line:

   collector-manager-da-hostname
   

   Save the file.

3. Update the IP address in the following file:

   /opt/IMDataCollector/apache-karaf-2.3.0/jms/local-jms-broker.xml
   

4. Delete the following file:

   /opt/IMDataCollector/apache-karaf-2.3.0/deploy/local-jms-broker.xml
   

5. Delete the cache. Open a command prompt and type the following command:

   rm -rf /opt/IMDataCollector/apache-karaf-2.3.0/data/cache/*
   

6. Start the Data Collector. Open a command prompt and type the following command:

   /etc/init.d/dcmd start
   

7. Make sure that the correct address appears in the Data Collector List.
   1. Open CA Performance Center as an administrator.
   2. Select Admin, Data Source Settings, and click a Data Aggregator data source.
   3. Click Data Collectors from the System Status menu.
   4. The IP address of each Data Collector appears under the 'Address' column.
   5. The status of each Data Collector is "Collecting Data".
