The endpoints role discovers targets from listed endpoints of a service. the target and vary between mechanisms. Below are examples of how to do so. This is generally useful for blackbox monitoring of an ingress. With this, the node_memory_Active_bytes metric which contains only instance and job labels by default, gets an additional nodename label that you can use in the description field of Grafana. write_relabel_configs is relabeling applied to samples before sending them Denylisting becomes possible once youve identified a list of high-cardinality metrics and labels that youd like to drop. It also provides parameters to configure how to If a container has no specified ports, Because this prometheus instance resides in the same VPC, I am using the __meta_ec2_private_ip which is the private ip address of the EC2 instance to assign it to the address where it needs to scrape the node exporter metrics endpoint: You will need a EC2 Ready Only instance role (or access keys on the configuration) in order for prometheus to read the EC2 tags on your account.

To enable denylisting in Prometheus, use the drop and labeldrop actions with any relabeling configuration. One of the following role types can be configured to discover targets: The node role discovers one target per cluster node with the address defaulting Serverset SD configurations allow retrieving scrape targets from Serversets which are sending a HTTP POST request to the /-/reload endpoint (when the --web.enable-lifecycle flag is enabled). are published with mode=host. service is created using the port parameter defined in the SD configuration. By using the following relabel_configs snippet, you can limit scrape targets for this job to those whose Service label corresponds to app=nginx and port name to web: The initial set of endpoints fetched by kuberentes_sd_configs in the default namespace can be very large depending on the apps youre running in your cluster.

The private IP address is used by default, but may be changed to undefined - Coder v1 Docs The currently supported methods of target discovery for a scrape config are either static_configs or kubernetes_sd_configs for specifying or discovering targets. Finally, this configures authentication credentials and the remote_write queue. Once the targets have been defined, the metric_relabel_configs steps are applied after the scrape and allow us to select which series we would like to ingest into Prometheus storage. configuration file.

Prometheus - Django app metrics are not collected For valid JSON. devops, docker, prometheus, Create a AWS Lambda Layer with Docker 2023 The Linux Foundation. This service discovery uses the public IPv4 address by default, but that can be WindowsyamlLinux. I've been trying in vai for a month to find a coherent explanation of group_left, and expressions aren't labels. They are set by the service discovery mechanism that provided Targets may be statically configured via the static_configs parameter or The following snippet of configuration demonstrates an allowlisting approach, where the specified metrics are shipped to remote storage, and all others dropped. Recall that these metrics will still get persisted to local storage unless this relabeling configuration takes place in the metric_relabel_configs section of a scrape job. To filter by them at the metrics level, first keep them using relabel_configs by assigning a label name and then use metric_relabel_configs to filter. How to use relabeling in Prometheus and VictoriaMetrics
