Configuring event suppression

Edit online

Event suppression is available as an action when creating a seasonal event rule. You can configure event suppression by modifying the NOI_DefaultValues properties file.

Before you begin

In Netcool® Operations Insight® 1.4.1.2 and later (corresponding to Netcool/Impact 7.1.0.13 and later) it is recommended to use the Event Analytics Configuration Wizard instead of the ./nci_trigger command to edit properties in the NOI Shared Configuration properties file.

For more information on the relevant section of the wizard, see Configuring event suppression.

About this task

To add details about suppressing and unsuppressing events, you must modify the NOI_DefaultValues properties file in the $IMPACT_HOME/bin directory.

Procedure

Log in to the server where IBM® Tivoli® Netcool/Impact is stored and running.
Generate a properties file containing the latest Event Analytics system settings.
1. Navigate to the directory $IMPACT_HOME/bin.
2. Run the following command to generate a properties file containing the latest Event Analytics system settings.
```
nci_trigger server_name username/password NOI_DefaultValues_Export
 FILENAME directory/filename
```
  Where:
  - server_name is the name of the server where Event Analytics is installed.
  - user name is the user name of the Event Analytics user.
  - password is the password of the Event Analytics user.
  - NOI_DefaultValues_Export is a Netcool/Impact policy that performs an export of the current Event Analytics system settings to a designated properties file.
  - directory is the directory where the properties file is stored.
  - filename is the name of the properties file.
  For example:
```
nci_trigger NCI impactadmin/impactpass NOI_DefaultValues_Export
 FILENAME /tmp/properties.props
```

Add the following lines of text to the properties file:

seasonality.suppressevent.column.name=SuppressEscl
seasonality.suppressevent.column.type=NUMERIC
seasonality.suppressevent.column.value=4
seasonality.unsuppressevent.column.name=SuppressEscl
seasonality.unsuppressevent.column.type=NUMERIC
seasonality.unsuppressevent.column.value=0

Import the modified properties file into Event Analytics.
1. Ensure you are in the directory $IMPACT_HOME/bin.
2. Run the following command to perform an import of Event Analytics system settings from a designated properties file.
```
nci_trigger server_name username/password NOI_DefaultValues_Configure
 FILENAME directory/filename
```
  Where:
  - server_name is the name of the server where Event Analytics is installed.
  - user name is the user name of the Event Analytics user.
  - password is the password of the Event Analytics user.
  - NOI_DefaultValues_Configure is a Netcool/Impact policy that performs an import of Event Analytics system settings from a designated properties file.
  - directory is the directory where the properties file is stored.
  - filename is the name of the properties file.
  For example:
```
nci_trigger NCI impactadmin/impactpass NOI_DefaultValues_Configure
 FILENAME /tmp/properties.props
```
