label_values prometheus filter

Other example: If you want to count the number of apps deployed in a kubernetes cluster based on different values of a label ( ex:app): count (count (kube_pod_labels {app . Prometheus query to count unique label values. 10 votes. For example, the following query converts the number of processed bytes by a simulated last batch job run into MiB: If we write our query as http_requests_total we'll get all time series named http_requests_total along with the most recent value for each of them. Every interval (for example 30s) app sends metrics to some endpoint in predefined format. Labels are intended to be used to specify identifying attributes of objects that are meaningful and relevant to users, but do not directly imply semantics to the core system. . You can specify custom label/value pairs to be sent along with each time series, using the external_labels block within the global section. We can combine sum with some label expressions, e.g. But only two metric names. The easiest example that I have in mind would be to filter "up" query to only retrieve down instances. Labels can be used to organize and to select subsets of objects. The optional to_nearest argument allows specifying the nearest multiple to which the sample values should be rounded. Some of the key features of Prometheus metrics monitoring are: Multi-dimensional data model Prometheus stores data as time-series. Filtering based on labels. Optionally, the log stream selector can be followed by a log pipeline. . This newly generated CSV-data is then being send via Kinesis to my telegraf agent where i preprocess the data and send it to my influxdb afterwards. You can run a variety of PromQL queries to pull interesting and actionable metrics from your Kubernetes cluster.These queries will give you insights into node health, Pod health, cluster resource utilization, etc. I hope this is helpful for you. and the label value is the unique sample value. A better option might be to tell Prometheus to respect selected labels when aggregating, e.g. Have a question about this project? 1) Push model. Field values are mapped to time series values. A scalar value is a simple numeric value without any labels. Labels are the index to Loki's log data. Prometheus console 11 Queries | Kubernetes Metric Data with PromQL. However, what if we try and game the system here. Watch the steps in this short video, and the written instructions are below the video. It allows you to specify any number of label/value filters on the fly. That allows you to filter those HTTP requests, enabling queries like "give me the requests with a 200 OK response for the handler /users ". ; maxTime: The current maximum timestamp in milliseconds. Enter a Name for your variable. collapse: (default false) The initial state of the row when opening the dashboard. 0. It was developed by SoundCloud. label_dp_topic="GEN". In my dashboard Add row -> SingleStat -> Metrics tab -> Query is : nodejs_version_info , now value displayed is 1. Ties are resolved by rounding up. to Prometheus Developers, pgppro.@gmail.com. It has a few values like these for example, which are the floor levels; V1 V2 V3 V4.. V11 etc Now I can't filter the gallery based on that value since it isn't a number, because the V in front of it. You can also store an optional set of key-value pairs called labels for that metric. Querying Prometheus. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Manipulating labels. ; chunkCount: The number of chunks. For example, it can store time-stamped values of the total number of HTTP requests received. Their behavior can be modified by providing bool after the operator, . varnish_main_client_req); One or more labels, which are simply key-value pairs that distinguish each metric with the same name (e.g. to get the number of all DE orders. vector/scalar, and vector/vector value pairs. Click the Totals & Filters tab Under Filters, add a check mark to 'Allow multiple filters per field.'. I noticed that if my pod has "service" label then the value of the pod is stored in InsightsMetrics.Tags.service field instead of the metric value and now I'm losing information about metric value. As a result, Prometheus collects a lot of metrics that you don't necessarily need all of the time. . We can further customize the query and filter results by adding label matchers, like http_requests_total{status="500 A label is a key-value attribute associated with a metric data point. Side note 2: Values are always floating-point numbers; timestamps are integers storing the number of milliseconds since the Unix epoch. label filters to the given <query>. Labels can be attached to objects at creation time and subsequently added and . (optional) In Label, enter the display name of the variable dropdown. For Loki to be efficient and cost-effective, we have to use labels responsibly. We can combine sum with some label expressions, e.g. Use the label_values({job!="blackbox"},instance) query to return labels for instances that are not monitored by a blackbox exporter. Prometheus is an open-source tool for collecting metrics and sending alerts. Example 1. For example, the following query would filter out time series with . Categories . By default they filter. This allows you to filter/scope metrics when using them, similar to setting an agent tag. Prometheus monitors Pod status via kube_pod_status_phase metric. The issue is same label_values doesnt work with query_result, can someone suggest me how can I append two labels and . Labels must be prefixed when used in queries: . VictoriaMetrics starts from the right part of the a and b query, e.g. We are going to customise Prometheus alerts by using external labels. SingleStat -> Options -> Value Stat (name) Go back to SingleStat Metrics -> Legend format { {version}} You can pick any label of the nodejs_version_info query. To do this effectively, you need to know every . Then it finds unique domain label values for the returned time series and passes an additional label filter on the domain label to the left part of the a and b query. The filter can select time series based on the data's project, group, monitored resource properties, and metric properties. There is a label in common between the two metrics "node_meta" and "node_disk_bytes_read": instance. Now comes the fun stuff. On the Variables tab, click New. I've recently deployed the second Kubernetes cluster into the homelab environment, and realised that if I send alerts to the same Slack channel, I can't tell which environment the alert somes from. Every unique combination of label and values defines a stream, and logs for a stream are batched up, compressed, and stored as chunks. Code. Creates a row. If you're confused by brian's answer: The result of filtering with a comparison operator is not a boolean, but the filtered series. Labels are key/value pairs that are attached to objects, such as pods. ; The value, which is a float64.When querying in the Prometheus console, the value . The following endpoint returns various cardinality statistics about the Prometheus TSDB: GET /api/v1/status/tsdb headStats: This provides the following data about the head block of the TSDB: . LogQL shares the same range vector concept from Prometheus, except the selected range of samples include a value of 1 for each log entry. 1 . We will create the variables using the Data sources set up in all the previous lessons. In the above example, there are four different time series. Export current metric values in OpenMetrics format or Prometheus format, suitable for import into an external monitoring system. @params. This page shows how to use regex to filter/modify values in the variable dropdown. You can use filters in the Monitoring API to do the following: Select the specific time series data that is returned from a list API request. You can filter those extra metrics out using PromQL. The annotations clause specifies a set of informational labels that can be used to store longer additional information such as alert descriptions or runbook links . In the next few lessons, we will look at how to create and use dashboard variables. Prometheus stores the instance or host name for every metric. Devs teams count will grow without any control, so I can't define the static regexp rules for `match_re`. I would very much like to see this feature implemented. Starting using Prometheus I'm looking for a way to filter some of my queries on the metric value. it executes label_copy(metric_1{instance="abc"}, "host", "domain"). Cool, 12 as expected. Returns a list of label values for the label in every metric. It is a good idea to add some limit for them, for example, only the first 10 descriptions: 5. The value of the label key2 is value2. Not being able to filter labels to specific hosts (or other attributes) means that I'm forced . Although this is not necessarily a feature most of our users would need (especially since Grafana effectively provides this with their label_values() function), I've hit a wall with a specific project using Prometheus as the backend data store. The parts are: Metric_name (e.g. 1. Navigate to the dashboard you want to make a variable for and then click the Dashboard settings (gear) icon at the top of the page. namespace="section-b4a199920b24b").Each metric will have at least a job label, which corresponds to the scrape config in the prometheus config. I want to create a query variable in grafana using Loki that returns all the possible label values of the label baz such that they only include label values that exist where the label foo equals "bar" . 2) Pull model. Filter prometheus results by metric value, not by label value Filtering is done with the comparison operators, for example x > 0 . Just want to follow up with some more information.. For selecting dynamically {__name__=~".+"} will get all of your metrics. From the documentation it is clear that function is intended to be used to replace some existing labels with the new values which are derivative of the existing labels. Variable of the type Query allows you to query Prometheus for a list of metrics, labels, or label values.

In 1.16 k8s deprecated the label kubernetes.io/role: worker I had previously been using as a filter to target graphs to specific node role using this in my grafana variables declaration label_values( Prometheus Metrics It allows you to specify any number of label/value filters on the fly. Prometheus query to count unique label values. This can be done with label_value () function from MetricsQL: count by (deployTime, foo) ( label_value (my_metric {foo=~"."}, "deployTime") > 1603284799 ) MetricsQL also supports now () function, which can simplify calculations for timestamp relative to the current time. Returns a list of label names. If you don't enter a display name . They are used to find the compressed log content, which is stored separately as chunks. Filter already allow us to select a set of metrics according to labels, but in some case, it would be useful to filter on the metric value. Rows are logical dividers within a dashboard and used to group panels together. For more information and examples, see Retrieving time series data. You can run a variety of PromQL queries to pull interesting and actionable metrics from your Kubernetes cluster.These queries will give you insights into node health, Pod health, cluster resource utilization, etc. I.e., a time series in Prometheus is defined by a combination of a metric name and a particular set of key-value labels. Log queries. . Prometheus supports the special ad hoc filters variable type. The Prometheus data source plugin provides the following functions you can use in the Query input field. For more information, refer to the Mozilla guide on Regular expressions. In the Type list, select Ad hoc filters. label_dp_language="eng-USA". *, so that character's length is very less in the query. Prometheus's query language supports basic logical and arithmetic operators. But without proper notification, we might spend too much time trying to understand what really is going on. I've made this formula to only get the floor level; If(Len(TestLabel.Text) = 2; Right(TestLabel.Text; 1); Right(TestLabel.Text; 2)) How to query prometheus to have sum of "disk bytes read" by instance/node/server . The label values can be templated. The result of an expression can either be shown as a graph, viewed as tabular data in Prometheus's expression browser, or consumed by external systems via the HTTP API. To change the Pivot Table option to allow multiple filters: Right-click a cell in the pivot table, and click PivotTable Options. It has the following primary components: The core Prometheus app - This is responsible for scraping and storing metrics in an internal time series database, or sending data to a remote storage backend.
