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 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 log 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.
