## Overview This component parses log files from other components and converts their logs to prometheus metrics that are then ingested by the monitoring Prometheus instance (the one created by the`components/monitoring` component). For more information on how this component reads log files and converts them to prometheus components see the [log-parser](https://github.com/DACCS-Climate/log-parser/) documentation. To configure this component: * set the `PROMETHEUS_LOG_PARSER_POLL_DELAY` variable to a number of seconds to set how often the log parser checks if new lines have been added to log files (default: 1) * set the `PROMETHEUS_LOG_PARSER_TAIL` variable to `"true"` to only parse new lines in log files. If unset, this will parse all existing lines in the log file as well (default: `"true"`) To view all metrics exported by the log parser: * Navigate to the `https://<BIRDHOUSE_FQDN>/prometheus/graph` search page * Put `{job="log_parser"}` in the search bar and click the "Execute" button Update the prometheus version to the current latest `v2.53.3`. This is required to support loading multiple prometheus scrape configuration files with the `scrape_config_files` configuration option. ## Changes **Non-breaking changes** - New component version prometheus:v2.53.3 **Breaking changes** - None ## Related Issue / Discussion - #444 ## Additional Information - implements parser given as an example here: #444 (comment) - this is an alternative to #474. See discussion in #444 to help decide which we should pick. ## CI Operations <!-- The test suite can be run using a different DACCS config with ``birdhouse_daccs_configs_branch: branch_name`` in the PR description. To globally skip the test suite regardless of the commit message use ``birdhouse_skip_ci`` set to ``true`` in the PR description. Using ``[<cmd>]`` (with the brackets) where ``<cmd> = skip ci`` in the commit message will override ``birdhouse_skip_ci`` from the PR description. Such commit command can be used to override the PR description behavior for a specific commit update. However, a commit message cannot 'force run' a PR which the description turns off the CI. To run the CI, the PR should instead be updated with a ``true`` value, and a running message can be posted in following PR comments to trigger tests once again. --> birdhouse_daccs_configs_branch: master birdhouse_skip_ci: false

Overview
Promtail and loki are components of the Grafana stack (see the monitoring component at
components/monitoring) that parses and ships logs to Grafana through loki.It can also generate prometheus metrics from the logs that it parses that can be ingested by the monitoring Prometheus instance (the one created by the
components/monitoringcomponent).Promtail can be deployed separately from loki if you just want to generate prometheus metrics.
For instructions on how to configure these components and start generating metrics see the documentation in
optional-components/README.md.Update the prometheus version to the current latest
v2.53.3. This is required to support loading multiple prometheus scrape configuration files with thescrape_config_filesconfiguration option.Changes
