-Get Metric
- [Documentation] Get the instant value of a metric from Prometheus using multiple filter parameters.
- ... The filter parameters are given to this function in key=value format (one argument per key/value pair).
- ... Fails if the metric is not found or has multiple values.
- ... Examples of execution:
- ... \${metric}= Get Metric \${prometheus_ip} \${prometheus_port} ${prometheus_password} \${metric}
- ... \${metric}= Get Metric \${prometheus_ip} \${prometheus_port} ${prometheus_password} \${metric} \${param1}=\${value1} \${param2}=\${value2}
-
- [Arguments] ${prometheus_ip} ${prometheus_port} ${prometheus_user} ${prometheus_password} ${metric} @{filter_parameters}
-
- ${filter}= Set Variable ${EMPTY}
- FOR ${param} IN @{filter_parameters}
- ${match} ${param_name} ${param_value} = Should Match Regexp ${param} (.+)=(.+) msg=Syntax error in filter parameters
- ${filter}= Catenate SEPARATOR= ${filter} ${param_name}="${param_value}",
- END
- ${resp}= Execute Prometheus Instant Query ${prometheus_host} ${prometheus_port} ${prometheus_user} ${prometheus_password} query=${metric}{${filter}}
- ${result_list}= Convert To List ${resp["data"]["result"]}
- ${results}= Get Length ${result_list}
- Should Not Be Equal As Numbers 0 ${results} msg=Metric ${metric} not found values=false
- Should Be Equal As Integers 1 ${results} msg=Metric ${metric} with multiple values values=false
- [Return] ${result_list[0]["value"][1]}

-
-Execute Prometheus Instant Query
- [Documentation] Execute a Prometheus Instant Query using HTTP API.
- ... Return an inline json with the result of the query.
- ... The requested URL is the next: http://\${prometheus_ip}:\${prometheus_port}/api/v1/query?\${querystring}
-
- [Arguments] ${prometheus_ip} ${prometheus_port} ${prometheus_user} ${prometheus_password} ${querystring}
- ${auth}= IF '${prometheus_password}'!='${EMPTY}' Create List ${prometheus_user} ${prometheus_password} ELSE Set Variable None
- Create Session prometheus http://${prometheus_ip}:${prometheus_port} timeout=${timeout} max_retries=${max_retries} verify=false auth=${auth}
- ${resp}= GET On Session prometheus /api/v1/query?${querystring} timeout=${timeout}
- Status Should Be 200 ${resp}
- [Return] ${resp.json()}
