Automate cluster status
-----------------------------


.. _19.2.1|VOSS-544|EKB-1727:

The *sysadmin* user has access to the 
**VOSS Automate Cluster** page (model: ``data/MonitoringCluster``), which displays aggregated 
Automate cluster Round Trip Delay Time (RTT) metrics at hourly and daily intervals.

.. note::

   * The retention period for data is 1 month.
   * This metric uses the same data as the ``cluster check`` CLI command. See *Cluster Check* in the 
     Platform Guide. 

* The **Interval** indicates the time interval for the entry: hourly or daily.

  Hourly intervals aggregate samples collected 15 minute intervals.
  Daily intervals aggregate hourly intervals.
* The **Start** and **End** values are the time stamps for the interval. The difference
  corresponds with the selected **Interval**.
* The **Source host** and **Destination port** are the IP addresses of the nodes
  in the cluster.
  
  * Port 27020: database connectivity
  * Port 8443: HTTPS connectivity

  For example, if **Source host** is ``192.168.100.7`` and  **Destination port** is ``192.168.100.6:27020``,
  then database connectivity is monitored between ``192.168.100.7`` and ``192.168.100.6:27020``.
* The **Failures** is the number of connection failures between **Source host** and **Destination port**
  over the interval. 

  Failures would also generate alerts if an SNMP trap is configured. 
* The **Avg TCP RTT (ms)** is the average RTT in milliseconds over the interval
  for a successful connection.
