Note!

This section only applies if you are using System Insight with InfluxDB for data storage.

If you require multiple InfluxDB databases which can also be written to as a back up, you can add additional databases to the System Insight service configuration as follows:

backupDBs="influxdb2"

            influxdb2 {
                database=mz
                password=dr
                url="http://127.0.0.1:18086"
                user=mzadmin
            }

For information on how to modify the System Insight service configuration using the mzsh topo command, see 2.7.2 Updating Service Configurations.

You can specify more than one database using a comma as a separator, as shown in the example below:

Example - How to add additional InfluxDB databases

system-insight {
    si-instance {
          config {
            akka-cluster=si
            influxdb {
                database=mz
                password=dr
                url="http://127.0.0.1:8086"
                user=mzadmin
            }

            backupDBs="influxdb2,influxdb3"

            influxdb2 {
                database=mz
                password=dr
                url="http://127.0.0.1:18086"
                user=mzadmin
            }

            influxdb3 {
                database=mz
                password=dr
                url="http://127.0.0.1:28086"
                user=mzadmin
            }
        }

        start-after=[
            "akka/si"
        ]
        template="1/standard/basic"
    }
}

If all InfluxDB instances are unreachable, System Insight runs in gated mode. In gated mode, metrics are dropped until at least one InfluxDB instance is reachable.
