I have a metric: node_state , which is used to verify the state of node.
topology:
types:
- name: custom:host
displayName: Host
rules:
- idPattern: Custom_host_{host}
instanceNamePattern: "{host}"
iconPattern: host

- key: custom_host
displayName: Custom_Host
pattern: "{host}"
- key: custom_host_id
displayName: Custom_Host_ID
pattern: "{host_id}"

- relatedEntity|entitySelectorTemplate=type(custom:host),fromRelationships.isSameAs($(entityConditions))
chartsCards:
- key: node_health_status
mode: NORMAL
displayName: Node Details
numberOfVisibleCharts: 4

visualizationType: GRAPH_CHART
graphChartConfig:
stacked: false
defaultAggregation: MAX
metrics:
- metricSelector: custom.node_state:splitBy(host)
visualization:
displayName: State
seriesType: COLUMN
If the value of node_state is 1 , it is marked as Bootstrapping
If the value of node_state is 2 , it is marked as Unhealthy
If the value of node_state is 3, it is marked as Healthy
How can I display the same on UI that whether the node is Healthy or Unhealthy ?
I checked in documentation that there is a type called message and a condition called metricAvailable.
Can you please give an example on how metricAvailable can be used in above condition.
Also, if I want to display Healthy/Unhealthy , is it good to use type:message
Also, for displaying chart , I used query: - metricSelector: custom.node_state:splitBy(host)
But the above query displays details of all the hosts on host screen.
