Health Data

The top 3 widgets display health data related to the Store.

Cluster Status

DetailDescriptionDesired State
ex-raw-trans

The general state of the Big Data store.

  • GREEN – Everything is working properly.
  • YELLOW – System is up and running, but there’s a problem requiring your attention (e.g. one of the nodes is down, but another node took over).
  • RED – There is a major problem with the Big Data store. DPOD is malfunctioning. Contact the support team.

Note: During the first 10-20 minutes following a system startup, a value of YELLOW or RED is normal.

GREEN

(RED and YELLOW acceptable during startup)

 

Shards

Details of the allocation of logical data to physical storage in the Big Data Store. All shards should be assigned, and unassigned shards number should be 0.

Note: During the first 10-20 minutes following a system startup, a value greater than zero is normal. 

If unassigned shards persist, see Error Accessing Store - Unassigned Shards.

0 Unassigned shards

(A larger than 0 value acceptable during startup)

ButtonsTwo buttons are available to the far right of the cluster status widget. Both the ES-head and ES-Visualize buttons are for DPOD support troubleshooting tasks. When required, DPOD support will guide you through the usage of these buttons.

Index Sets

This list displays the data sets that store DPOD data.

...

The data disk retention is automatically managed by DPOD. For each type of data (transactional, resources, payload, etc.), once its quota is full, old data will be discarded to make room for new data of the same type. A bigger disk size will hold a longer history.

Nodes

These are the data nodes which the Store uses for its internal processing.

DetailDescriptionDesired State
NameNode Name
VersionNode VersionAll versions should be the same
Host NameNode's host name
Type

A correctly set up system should have at least one ‘D’ node (data processing node),
and an odd number of ‘M’ nodes (master nodes).

  • D Nodes > 0
  • Odd M Nodes number 

Nodes Health

The Nodes Health table contains additional information about the ElasticSearch nodes (for example, the amount of swap space used, average time to index documents, etc).
