Configuring rate events to a user-configured cell

Rate events like ALARM and ABNORMALITIES are generated by the Rate process that can be configured to be processed in a custom cell instead of the default Infrastructure Management Server cell. After the events are processed in the user-configured cell, the events are then propagated to the Infrastructure Management Server cell.

The following sections help you to configure the rate events to be processed in a user-configured cell that are sent to the Infrastructure Management Server cell:

To configure rate events from a user-configured cell to the Infrastructure Management Server cell in a standalone deployment

  1. Create a new cell by running the mcrtcell command. Consider this as a rate cell. For more information about mcrtcell command, see mcrtcell.

  2. Using a text editor, open the mcell.conf file located in the pw\server\etc\<cell> directory location and update the POMEnabled property as shown in the following code block: 

    POMEnabled=No

    Note: Replace <cell> with the rate cell name in the preceding directory location that is pw\server\etc\<cell>.

  3. Copy the mcell.propagate file from the pw\server\etc directory to pw\server\etc\<cell>. 

  4. Edit the mcell.propagate file located in the pw\server\etc\<cell> directory location as shown in the following code block: 

    mc_parameter_threshold=f
    mc_tool_key=f

  5. Update the refine_multiple_server_events.mrl file located in the pw\server\etc\<cell>\kb\rules directory location of the Infrastructure Management Server cell. Comment out the code lines as shown in the following example:

    #refine initialize_ppm_ev:
    #PPM_EV ($EV)
    #{
    #if (listlen($EV.mc_history) != 0) then
    #{
    #$EV.pn_object_id = 0;
    #$EV.pn_object_class_id = 0;
    #$EV.pn_parameter_id = 0;
    #opadd($EV, "Initialized PPM_EV slots specific to CI association", "");
    #};
    #}
    #END
  6. Recompile the Knowledge Base of the Infrastructure Management Server cell.

  7. Update the rate cell details in the pronet.conf file located in the pw\custom\conf directory location of the Infrastructure Management Server cell as shown in the following code block: 

    pronet.rate.cell.cellName=<rate cell name>
  8. Create a propagation policy or rule on the rate cell to propagate events to the Infrastructure Management Server cell.
  9. Restart the Infrastructure Management server by using the pw system start command.

To configure rate events from a user-configured cell to the Infrastructure Management Server cell in a high-availability deployment

  1. Deploy the Rate cells in the high-availability mode, if the Infrastructure Management Servers are deployed in high-availability.
    Note: During an upgrade, ensure that the remote rate cells are also upgraded. 
  2. Perform the steps that are listed for the standalone Infrastructure Management Server first on primary followed by secondary Infrastructure Management computer.

Best practices - Rate events

  • Do not delete the Alarm and abnormality events from the user-configured rate cell using any of the following options. If deleted, changes are not reflected in the Rate database:

    • The mquery command
    • Event processing rules (MRL)
    • Event rules in the operator console

    Note: If the events are closed internally through the Rate engine, the changes are reflected in the Rate database.

  • If you inadvertently delete the Alarm and abnormality events using one of the three options stated above, run one of the following commands to synchronize the Rate and the cell database:

    • pw eventsync -c alarmabnormality

    • pw eventsync -d <duration of batch in minutes>

      The events will be fetched in a batch of duration specified in minutes starting from current time till the time of earliest open event. If the number of events are less, you can specify a larger time duration for the batch and if the number of events are more, specify a smaller time duration for the batch. If time duration is not specified, default time duration is 60 minutes.

  • If you have customized KBs in your rate cell, when you upgrade, the installer overwrites the existing rate cell KB files present in the <Infrastructure Management Installation Directory>\pw\server\etc\cellName directory. After upgrading, you must merge these KBs with the help of the backed up files. For details, see Using the mmigrate utility.
    Note: During the upgrade, existing cell KB files are backed up as pw\server\etc\<cell_name>.org.
