Change Log

All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning and Keep a changelog.

0.3.9 / 2024-12-14

  • removed passwd_encrypt tool source code from httpapi_exporter: created a new stand-alone package passwd_encrypt. Passwd_encrypt is still installed when building and added to the released archiv.
  • updated prometheus/exporter-toolkit to 0.13.0 (log => log/slog)
  • renamed entrypoint /healthz to /health : response format depends on "accept" header (application/json, text/plain, text/html default)
  • updated entrypoint /status, /loglevel /targets /config: response format depends on "accept" header (application/json, text/plain, text/html default)
  • added cmd line --model_name to perform test with model and uri in dry-run mode
  • added out format for passwd_encrypt that can be cut/pasted into config file.
  • added InvalidLogin error cases: no cipher (auth_key not provided) or (invalid auth_key). For those cases if target is up, metrics for collectors status will return code 2; invalid_login
  • added GET /loglevel to retrieve current level, add POST /loglevel[/level] to set loglevel to level directly
  • added debug message for basic auth (auth_config.mode=basic) and bearer (auth_config.mode=token)
  • loglevel link in landing page
  • fixed typos
  • upgrade go version and modules, security fixed (golang.org/x/crypto)

0.3.8 / 2024-05-20

  • fixed minor bug with basic auth, remove unused vars ...
  • fixed typos.
  • reorganized contribs dirs

BREAKING CHANGES

  • rename attribute "auth_mode" to auth_config in query_action and target definition:

    before:

    targets:
  # default target is used as a pattern for exporter queries with target name not defined locally.
  - name: default
    scheme: https
    host: set_later
=>    auth_mode:
      # mode: basic|token|[anything else:=> user defined login script]
      mode: script
      user: usrNetScalerSupervision
      password: "/encrypted/base64_encrypted_password_by_passwd_crypt_cmd"
    collectors:
      - ~.*_metrics

    now:

    targets:
  # default target is used as a pattern for exporter queries with target name not defined locally.
  - name: default
    scheme: https
    host: set_later
    auth_name: prometheus_encrypted
    auth_config:
      # mode: basic|token|[anything else:=> user defined login script]
      mode: script
      user: usrNetScalerSupervision
      password: "/encrypted/base64_encrypted_password_by_passwd_crypt_cmd"
    collectors:
      - ~.*_metrics

  • add POST /reload and /loglevel entry points to respectively do a reloadConfig and increase loglevel.

  • build a specific windows code version without SIGUSR2 signal (used for loglevel cycling).

0.3.7 / 2024-04-21

  • added support for env vars in auth_config #1 : included from branch dev_issued_1
  • upgraded to go 1.22.2
  • upgraded to latest modules' version
  • fixed cookie sessions (bug found with arubacx cnx)
  • added contribs arubacx-os

0.3.6 / 2024-02-11

  • upgraded to go 1.22
  • upgraded to latest modules' version

0.3.5 / 2024-02-11

  • fix panic when var is not found for metric

  • fix target parsing when exporter is used in proxy mode: allow formats

    • target=host.domain : use default scheme and default port
    • target=host.domain:port : use default scheme

  • added status value for collector_status metric :

    • 0: error
    • 1: ok
    • 2: invalid log
    • 3: timeout

  • added new "template" format: $varname that allow a direct accept to variable in symbols table. it is easier to use this format for loop interaction. e.g.:

    loop: "{{ .item.list | toRawJson }}"

    can be replaced by: e.g.:

    loop: $item.list

  • added a new template func "lookupAddr" to retrive DNS hostname from ip address.

  • adapt contribs (netscaler/veeam) with new features.

0.3.4 / 2023-12-16

  • fixed var evaluation (set_fact with template)
  • fixed type evalution for cookies and header
  • (beta) add set_stats action to store vars (and values) from collector into target global symbols table, so they are persistent accross several runs; used to get config datas only once or at periodic time.
  • updated go version to 1.21.5
  • updated contrib netscaler (lb services, ssl services, rename metrics from system collector)
  • fixed template panic: add recover

0.3.3 / 2023-11-05

  • add auth_key argument for cli in dry_mode
  • add log.level cycling with signal USER2
  • add Authconfig, dynamic targets
  • fix logout with cookies set
  • fix clear script calls
  • fix global scrape timeout detection
  • fix scrape timeout by target
