Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[4.6.0] - 2023-02-09

Changed

  • #51 Ensure that idle HTTP client connections are closed after collecting metrics.
  • Corrected the import path to reflect the actual repository.

[4.5.1] - 2020-09-14

Fixed

  • #43 Ensuring that the logging reflects a custom bind port. Previously the logging was being setup in init which was before the flags are parsed.

[4.5.0] - 2020-07-25

Added

  • #41 Added the following AAA metrics.
    • aaa_auth_success
    • aaa_auth_fail
    • aaa_auth_only_http_success
    • aaa_auth_only_http_fail
    • aaa_current_ica_sessions
    • aaa_current_ica_only_connections

[4.4.0] - 2020-07-02

Added

  • #37 Added LBVS and GSLB VS state metric.

[4.3.1] - 2020-07-02

Fixed

  • #13 Error when trying to retrieve stats for servicegroups which have multiple members, where each member is the same server but on different ports. We now include the port as a label to avoid duplicates.

[4.3.0] - 2020-01-24

Added

  • VPN Virtual Server (NetScaler Gateway) stats.

[4.2.0] - 2019-12-31

Changed

  • Minimising the number of API requests needed to retrieve Service Group member stats by getting all service group members for a specific service group in one go. We still have to query for every single service group, but it cuts down the number of API requests by over 50% on the assumption that each service group has multiple members.
  • Refactored the filenames to better reflect the functions contained within them.

[4.1.0] - 2019-12-30

Changed

  • Debug logging is now hidden behind the --debug flag.

[4.0.0] - 2019-07-19

Added

  • Multi query endpoint. You no longer need to run a single instance per NetScaler you want to monitor. The exporter now supports Prometheus targets so only one instance is required.
  • Return a 500 status code, and error message, if the NetScaler target cannot be contacted.

Changed

  • Refactored exporter code into separate package for maintainability reasons.

Removed

  • Option to specify a NetScaler to scrape from the command line. Using Prometheus scrape targets is now the only way.

[3.2.0] - 2018-12-12

Added

  • Collection of GSLB Service metrics.
  • Collection of GSLB Virtual Server metrics.
  • Collection of Content Switching Virtual Server metrics.
  • Make now also builds Linux x64 executables.

[3.1.0] - 2018-05-02

Added

  • Option to ignore certificate errors. This can be useful when the NetScaler uses a self-signed certificate which will error without this flag. It should be used sparingly, and only when you fully trust the endpoint.

[3.0.0] - 2018-05-01

Added

  • The following metrics replace their equivalent rate/s.
    • total_received_mb
    • total_transmit_mb
    • http_responses
    • http_requests
    • interfaces_received_bytes
    • interfaces_received_bytes
    • interfaces_received_packets
    • interfaces_transmitted_packets
    • interfaces_jumbo_packets_received
    • interfaces_jumbo_packets_transmitted
    • interfaces_error_packets_received

Removed

  • The following metrics are not needed as Prometheus can calculate them from their equivalent totals.
    • transmit_mb_per_second
    • received_mb_per_second
    • http_requests_rate
    • http_responses_rate
    • interfaces_received_bytes_per_second
    • interfaces_received_bytes_per_second
    • interfaces_received_packets_per_second
    • interfaces_transmitted_packets_per_second
    • interfaces_jumbo_packets_received_per_second
    • interfaces_jumbo_packets_transmitted_per_second
    • interfaces_error_packets_received_per_second
    • virtual_servers_hits_rate
    • virtual_servers_requests_rate
    • virtual_servers_responses_rate
    • virtual_servers_request_bytes_rate
    • virtual_servers_reponse_bytes_rate
    • service_throughput_rate
    • service_request_rate
    • service_responses_rate
    • service_request_bytes_rate
    • service_response_bytes_rate
    • service_virtual_server_service_hits_rate
    • servicegroup_requests_rate
    • servicegroup_responses_rate
    • servicegroup_request_bytes_rate
    • servicegroup_response_bytes_rate

[2.0.0] - 2017-10-10

Changed

  • Log entries are no longer sent to a file. Instead they are logged to stdout in logfmt format.

[1.4.1] - 2017-08-22

Fixed

  • NetScaler API bug meant that trying to retrieve stats from a service group member which used a wildcard port (65535 in API and CLI, * in GUI) resulted in error. Skipping these members until the bug is resolved.

[1.4.0] - 2017-07-25

Changed

  • Authentication to the NetScaler now only happens once per scrape; the session cookie is saved and re-used in future requests. When the scrape finishes, the session is disconnected. Previously each API request was authenticated individually.

[1.3.0] - 2017-07-21

Added

  • Exporting Service Group metrics

[1.2.0] - 2017-07-21

Added

  • Added service state; 1 if service is up and 0 for any other state.

[1.1.0] - 2017-07-20

Added

  • Added model_id which represents, on the VPX line at least, the maximum licensed throughout of the appliance. For example a VPX 1000 allows for 1000 MB/s.

[1.0.0] - 2017-07-15
