Querying Consul With Grafana

usecase

The concern is documenting getting consul queries in grafana

1. variables

1.1. create consul datasource

• create a Consul variable as a datasource type → select Consul
• difference is that here, you can use also KEYS (not tree leaves) as values

1.2. create consul query

• create a ConsulQuery variable as a query → select $Consul as a datasource
• but how could I create the queries made out of variables — well, most probably
• you have to be using those, the only variable I can think of is, however, only customer, can you create another one

2. queries

• You can just query consul
• here I would like to know now many nodes each client has in their ES cluster

2.1. navigation: no whitespace, relative paths

• in columns, no spaces are allowed
• navigate with relative paths

2.2. retrieve key directly

2.3. get selected keys from a parent node

• either select a leaf such as

customer/${customer}/aws_elasticsearch_prod1/input/volume_size

• and then add other leaves to is in columns

./,../instance_count/,../instance_type/

2.4. columns

• seems like that is going from the query

• so if you query

customer/*/aws_setup_prod1/input/client_name

• you put the following as columns

./,../uuid

• to have the result of the query as a columns in and of itself, use ./
