The following metrics are accessible through SNMP and JMX and are intended to be used for the monitoring of the administrative nodes in the Oracle NoSQL Database cluster.
adminId – The unique ID for the admin node.
adminServiceStatus – The status of the administrative service. It can be one of the follows:
unreachable(0) – The admin node unreachable. This can be due to a network error or the admin node maybe down.
starting (1) – The admin node agent is booting up.
waitingForDeploy (2) – Indicates a bootstrap admin that has not been configured, that is, it has not been given a store name. Configuring the admin triggers the creation of the Admin database, and changes its status from "WAITING_FOR_DEPLOY" to "RUNNING".
running(3) – The admin node is running.
stopping(4) – The admin node in the process of shutting down.
stopped(5) – An intentional clean shutdown of the admin node.
errorRestarting(6) – The storage node tried to start the admin several times without success and gave up.
errorNoRestart(7) – Service is in an error state and will not be automatically restarted. Administrative intervention is required.
adminHttpPort – The port that the admin is listening for incoming HTTP requests.
adminLogFileCount – A logging config parameter that represents the maximum number of log files that are retained by the admin node.
adminLogFileLimit – A logging config parameter that represents the maximum size of a single log file in bytes.
adminPollPeriod – The frequency by which the Admin polls agents (replication node and sna) for statistics. This polling receives service status changes, performance metrics, and log messages. This period is reported in units of milliseconds.
adminEventExpiryAge – Tells how long critical events are saved in the admin database. This value is reported in units of hours.
adminIsMaster – A Boolean value which indicates whether or not this admin node is the master node for the admin group.
