"This update fixes the following issues :

golang-github-prometheus-prometheus :

Add support for Uyuni/SUSE Manager service discovery

  + Added 0003-Add-Uyuni-service-discovery

Readded _service file removed in error.

Update to 2.11.1

  + Bug Fix :

  - Fix potential panic when prometheus is watching multiple
    zookeeper paths.

Update to 2.11.0

  + Bug Fix :

  - resolve race condition in maxGauge.

    since rewriting remote-write to utilize the
    write-ahead-log)

  - The meta file BlockStats no longer holds size
    information. This is now dynamically calculated and kept
    in memory. It also includes the meta file size which was
    not included before

  - Renamed metric from
    prometheus_tsdb_wal_reader_corruption_errors to
    prometheus_tsdb_wal_reader_corruption_errors_total

  + Features :

  - Provide option to compress WAL records using Snappy.

  + Enhancements :

  - Create new clean segment when starting the WAL.

  - Reduce allocations in PromQL aggregations.

  - Add storage warnings to LabelValues and LabelNames API
    results.

  - Add prometheus_http_requests_total metric.

  - Enable openbsd/arm build.

  - Remote-write allocation improvements.

  - Query performance improvement: Efficient iteration and
    search in HashForLabels and HashWithoutLabels.

  - Allow injection of arbitrary headers in promtool.

  - Allow passing external_labels in alert unit tests
    groups.

  - Allows globs for rules when unit testing.

  - Improved postings intersection matching.

  - Reduced disk usage for WAL for small setups.

  - Optimize queries using regexp for set lookups.

Rebase patch002-Default-settings.patch

Update to 2.10.0 :

  + Bug Fixes :

  - TSDB: Don't panic when running out of disk space and
    recover nicely from the condition

  - TSDB: Correctly handle empty labels.

  - TSDB: Don't crash on an unknown tombstone reference.

  - Storage/remote: Remove queue-manager specific metrics if
    queue no longer exists.

  - PromQL: Correctly display {__name__='a'}.

  - Discovery/kubernetes: Use service rather than ingress as
    the name for the service workqueue.

  - Discovery/azure: Don't panic on a VM with a public IP.

  - Web: Fixed Content-Type for js and css instead of using
    /etc/mime.types.

  - API: Encode alert values as string to correctly
    represent Inf/NaN.

  + Features :

  - Template expansion: Make external labels available as
    $externalLabels in alert and console template expansion.

  - TSDB: Add prometheus_tsdb_wal_segment_current metric for
    the WAL segment index that TSDB is currently writing to.
    tsdb

  - Scrape: Add scrape_series_added per-scrape metric. #5546

  + Enhancements

  - Discovery/kubernetes: Add labels
    __meta_kubernetes_endpoint_node_name and
    __meta_kubernetes_endpoint_hostname.

  - Discovery/azure: Add label
    __meta_azure_machine_public_ip.

  - TSDB: Simplify mergedPostings.Seek, resulting in better
    performance if there are many posting lists. tsdb

  - Log filesystem type on startup.

  - Cmd/promtool: Use POST requests for Query and
    QueryRange. client_golang

  - Web: Sort alerts by group name.

  - Console templates: Add convenience variables $rawParams,
    $params, $path.

Upadte to 2.9.2

  + Bug Fixes :

  - Make sure subquery range is taken into account for
    selection

  - Exhaust every request body before closing it

  - Cmd/promtool: return errors from rule evaluations

  - Remote Storage: string interner should not panic in
    release

  - Fix memory allocation regression in mergedPostings.Seek
    tsdb

Update to 2.9.1

  + Bug Fixes :

  - Discovery/kubernetes: fix missing label sanitization

  - Remote_write: Prevent reshard concurrent with calling
    stop

Update to 2.9.0

  - Add GODEBUG and retention to the runtime page.

  - Add support for POSTing to /series endpoint.

  - Support PUT methods for Lifecycle and Admin APIs.

  - Scrape: Add global jitter for HA server.

  - Check for cancellation on every step of a range
    evaluation.

  - String interning for labels & values in the remote_write
    path.

  - Don't lose the scrape cache on a failed scrape.

  - Reload cert files from disk automatically. common

  - Use fixed length millisecond timestamp format for logs.
    common

  - Performance improvements for postings. Bug Fixes :

  - Remote Write: fix checkpoint reading.

  - Check if label value is valid when unmarshaling external
    labels from YAML.

  - Promparse: sort all labels when parsing.

  - Reload rules: copy state on both name and labels.

  - Exponentation operator to drop metric name in result of
    operation.

  - Config: resolve more file paths.

  - Promtool: resolve relative paths in alert test files.

  - Set TLSHandshakeTimeout in HTTP transport. common

  - Use fsync to be more resilient to machine crashes.

  - Keep series that are still in WAL in checkpoints.

Update to 2.8.1

  + Bug Fixes

  - Display the job labels in /targets which was removed
    accidentally

Update to 2.8.0

  + Change :

  - This release uses Write-Ahead Logging (WAL) for the
    remote_write API. This currently causes a slight
    increase in memory usage, which will be addressed in
    future releases.

  - Default time retention is used only when no size based
    retention is specified. These are flags where time
    retention is specified by the flag
    --storage.tsdb.retention and size retention by

    --storage.tsdb.retention.size.

  - prometheus_tsdb_storage_blocks_bytes_total is now
    prometheus_tsdb_storage_blocks_bytes.

  + Feature :

  - (EXPERIMENTAL) Time overlapping blocks are now allowed;
    vertical compaction and vertical query merge. It is an
    optional feature which is controlled by the
    --storage.tsdb.allow-overlapping-blocks flag, disabled
    by default.

  + Enhancements :

    	- Use the WAL for remote_write API.

  - Query performance improvements.

  - UI enhancements with upgrade to Bootstrap 4.

  - Reduce time that Alertmanagers are in flux when
    reloaded.

  - Limit number of metrics displayed on UI to 10000.

  - (1) Remember All/Unhealthy choice on target-overview
    when reloading page. (2) Resize text-input area on Graph
    page on mouseclick.

  - In histogram_quantile merge buckets with equivalent le
    values.

  - Show list of offending labels in the error message in
    many-to-many scenarios.

  - Show Storage Retention criteria in effect on /status
    page.

  + Bug Fixes :

  + Fix sorting of rule groups.

  + Fix support for password_file and bearer_token_file in
    Kubernetes SD.

  + Scrape: catch errors when creating HTTP clients

  + Adds new metrics: prometheus_target_scrape_pools_total
    prometheus_target_scrape_pools_failed_total
    prometheus_target_scrape_pool_reloads_total
    prometheus_target_scrape_pool_reloads_failed_total

  + Fix panic when aggregator param is not a literal.
