Validating collector installation

To verify that the collector is ready to receive events:

1. In the KUMA web interface, open Resources → Active services.
2. Make sure that the collector you installed has the green status.

If the status of the collector is not green, view the log of this service on the machine where it is installed, in the /opt/kaspersky/kuma/collector/<collector ID>/log/collector directory. Errors are logged regardless of whether debug mode is enabled or disabled.

If the collector is installed correctly and you are sure that data is coming from the event source, the table should display events when you search for events associated with the collector.

To check for normalization errors using the Events section of the KUMA web interface:

1. Make sure that the Collector service is running.
2. Make sure that the event source is providing events to the KUMA.
3. Make sure that you selected Only errors in the Keep raw event drop-down list of the Normalizer resource in the Resources section of the KUMA web interface.
4. In the Events section of KUMA, search for events with the following parameters:
   • ServiceID = <ID of the collector to be checked>
   • Raw != ""

If any events are found with this search, it means that there are normalization errors and they should be investigated.

To check for normalization errors using the Grafana Dashboard:

1. Make sure that the Collector service is running.
2. Make sure that the event source is providing events to the KUMA.
3. Open the Metrics section and follow the KUMA Collectors link.
4. See if the Errors section of the Normalization widget displays any errors.

If there are any errors, it means that there are normalization errors and they should be investigated.

For WEC and WMI collectors, you must ensure that unique ports are used to connect to their agents. This port is specified in the Transport section of Collector Installation Wizard.
