Click to monitor multiple database instances in a consolidated view, and aggregate metrics of multiple databases. To monitor a custom cluster, you can add additional hostname or IP address, and port details for each sub-collector. You can add up to a total of 29 sub-collectors. Thereby, 30 databases can be monitored in a custom cluster. In addition to the licenses consumed by the main collector, each sub-collector consumes one or more licenses, depending on the database type.
All connection parameters other than the hostname or IP address, and port details of the sub-collector are the same as the main collector. If you want to specify different parameters for the sub–collectors, while creating or editing the collector configuration, you can do that only via the Create Collector API.
- You cannot convert a custom cluster collector to a standalone collector. If you want to monitor a standalone database, delete the entire custom cluster collector and create a fresh standalone collector. However, note that deleting the custom cluster collector will delete all its historical data.
