Relabel_config that creates the intermediate label _host_ from This means that any time Kubernetes service discovery is used, there must be a (using either $HOSTNAME or the hostname reported by the kernel if the Promtail looks for a _host_ label onĮach target and validates that it is set to the same hostname as Promtail’s Targets, it can only read log files from pods that are running on the same nodeĪs the one Promtail is running on. Note that while Promtail can utilize the Kubernetes API to discover pods as It is set to the absolute path of the file the line The label filename is added for every file found in _path_ to ensure the The _path_exclude_ label is another special label Promtail uses afterĭiscovery, to exclude a subset of the files discovered using _path_ fromīeing read in the current scrape_config block.

For a full list of options check out the docs for the library Promtail uses.
Wildcards are allowed, for example /var/log/*.log to get all files with a log extension in the specified directory, and /var/log/**/*.log for matching files and directories recursively. The _path_ label is a special label which Promtail uses after discovery toįigure out where the file to read is located. Refer toįor the full list of Kubernetes meta labels. ( _meta_kubernetes_namespace) or the name of the container inside the pod Kubernetes metadata, such as the namespace of the pod Other labels starting with _meta_kubernetes_* exist based on other _meta_kubernetes_pod_label_name with a value set to foobar. The scrape_configs section will receive an internal label Labels starting with _meta_kubernetes_pod_label_* are “meta labels” whichĪre generated based on your Kubernetes pod’s labels.įor example, if your Kubernetes pod has a label name set to foobar, then Sent to Grafana Loki, rename them so they don’t start with _. They usuallyĬome from dynamic sources like service discovery. Labels starting with _ (two underscores) are internal labels. There are different types of labels present in Promtail: If more than one scrape config section matches your logs, you will get duplicateĮntries as the logs are sent in different streams likely with slightly Scrape_configs contains one or more entries which are executed for eachĭiscovered target (i.e., each container in each new pod running in the The scrape_configs section in the config YAML. Promtail discovers locations of log files and extract labels from them through Scraping Promtail Scraping (Service Discovery) File Target Discovery
