Change the Config File for the First Time
In order to use SDS for the first time, the user must perform the following operations:
-
Set the kafka_servers parameter in the
sds.cfg file to the bootstrap server(s) for their kafka
installation; for example,
kafka_servers = "kafkahost:9092"
orkafka_servers = "kafkahost1:9092,kafkahost2:9092"
-
If publishing using the Confluent Schema Registry, then the following steps are
also needed:
- Upload the schema files to the schema registry and note the IDs assigned to each schema.
- Assign the schema registry IDs discovered in step 1 to the events in the sds.cfg file (see Event specific configuration below)
For the initial release the Kafka published events are:
Event Name | Description | Schema File | Default Topic |
---|---|---|---|
project | (relatively) Static project information that may be useful to join with time series data | vov-projects | |
taskers | Metrics related to the state and capacity of the taskers | metrics.taskers.avsc | vov-metrics-taskers |
jobs | Metrics related to the number of jobs in specific states and rate of dispatch/completion | metrics.jobs.avsc | vov-metrics-jobs |
scheduler | Metrics related to scheduler performance, sizes, clients, innerloop timers | metrics.scheduler.avsc | vov-metrics-scheduler |
