Let's show the value of the all-time time series with the counter metric prometheus_http_requests_total. This will show us all of the data denoted by this metric name, or "key". 2. Now, let's take a look at the same metric as in example 1, but add some labels. Let's add the values for the labels "job" and "code".Using regular expressions, you could select time series only for jobs whose name match a certain pattern, in this case, all jobs that end with server: http_requests_total{job=~".*server"} All regular expressions in Prometheus use RE2 syntax. To select all HTTP status codes except 4xx ones, you could run: http_requests_total{status!~"4.."} Subquery If we are monitoring complex systems, we might get metrics on different connected entities from different metric providers. The label naming might not be 100% aligned, i.e. in Kubernetes we get container metrics with a pod_name label from cAdvisor and metrics with a pod label from kube-state-metrics. The values are the same pod identifying names.An Intro to PromQL: Basic Concepts & Examples. Gedalyah Reback. Feb 16th, 2021. PromQL, short for Prometheus Querying Language, is the main way to query metrics within Prometheus. You can display an expression's return either as a graph or export it using the HTTP API.

However, we're not specifying any match group's in our replacement string, so the entire string is just copied into target_label. This is just a very specific case of how you can use a relabel_config to copy (parts of) a label into another (new) label. All regular expressions in Prometheus use the RE2 syntax. Data Types Scalar.

Let's show the value of the all-time time series with the counter metric prometheus_http_requests_total. This will show us all of the data denoted by this metric name, or "key". 2. Now, let's take a look at the same metric as in example 1, but add some labels. Let's add the values for the labels "job" and "code".Prometheus label replace example. But there is nice feature called projected volumes which gets around the issue. --. GaugeMetricFamily(). Installation For example, to collect CPUMonitoring disk I/O on a Linux system is crucial for every system administrator.. When performing basic system troubleshooting, you want to have a complete overview of every single metric on your system : CPU, memory but more importantly a great view over the disk I/O usage..

In the example above, we'll have ~20-30 log lines from a single http request. It would be convenient if we somehow could group them together, for example based on a unique X-Request-Id value. And then use that in the UI to see all related log lines together easily. 3.

Regex Prometheus uses RE2 regular expression They are anchored: bar regex will not match foobar Unanchor with .*bar.* You can use capture groups: (.*)bar used against foobar will create a variable $1 whose value is fooThe default regex wil always match, which causes the replacement to be carried out. However, we're not specifying any match group's in our replacement string, so the entire string is just copied into target_label. This is just a very specific case of how you can use a relabel_config to copy (parts of) a label into another (new) label.Prometheus monitors Pod status via kube_pod_status_phase metric. It has a phase label and if the Pod is in that given phase, the call returns a value of 1, otherwise it returns 0. This means that all our labels are always listed but the query returns a different result depending on whether that label is the actual status of the pod.Prometheus Real Estate Group San Mateo, CA Just now Be among the first 25 applicants See who Prometheus Real Estate Group has hired for this role The ingress controller supports case insensitive regular expressions in the spec.rules.http.paths.path field.
