Load Balancing for Data Collectors Pulling in Non-SNMP (CAMM) Data

Data Collector load balancing by moving devices and components from one Data Collector instance to another only applies to devices and components being monitored via SNMP or ICMP. For Data Collector instances that are pulling in Non-SNMP data via CAMM that require a rebalancing of resources, you can do this by distributing Device Pack engines to other hosts in the environment. Here are the instructions on how to perform this rebalancing.

  1. Install a Local Controller (LC) on new server and point to the appropriate Multi Controller (MC) server during the Installation
  2. After LC is successfully installed in new server check that CAMM web shows two LCs.
    1. Open CAMMWEB -
    2. Click on Hosts – Installed LC (new server) should be visible
  3. Using CAMMWEB Select the new server and deploy the devicepack engines to be migrated
  4. Log in to the MC server and navigate to:

    $CAMM_INSTALL/MC/repository/<OLD_SEVER_IP>/COMPONENTS directory

  5. Execute the following:

    ‘cp –R ENGINE_<devicepack> $CAMM_INSTALL/MC/repository/<NEW_SEVER_IP>/COMPONENTS/’

  6. If the devicepack to be migrated uses sftp/ftp/copy mechanism as data acquisition then
    1. create following directories under $CAMM_INSTALL/LC/repository/COMPONENTS/ENGINE_<devicepack>/ in NEW_SERVER
      • tmp directory under $CAMM_INSTALL/LC/repository/COMPONENTS/ENGINE_<devicepack>/tmp/input/inventory
      • input directory under $CAMM_INSTALL/LC/repository/COMPONENTS/ENGINE_<devicepack>/tmp/input/performance
    2. Copy the following files from OLD_SERVER to NEW_SERVER
      • $CAMM_INSTALL/COMPONENTS/ENGINE_<devicepack>/tmp/input/inventory/.historyFile.Inventory to $CAMM_INSTALL/LC/repository/COMPONENTS/ENGINE_<devicepack>/tmp/input/inventory
      • $CAMM_INSTALL/COMPONENTS/ENGINE_<devicepack>/tmp/input/performance/.historyFile.Performance to $CAMM_INSTALL/LC/repository/COMPONENTS/ENGINE_<devicepack>/tmp/input/performance
  7. Start the devicepack from CAMMWEB.
