  • Initial release

18 Jul 2016

  • Changed structures so that most applications will not need to use cgo to imbed the MQ C headers
    • Go programs will now use int32 where C programs use MQLONG
    • Use of message handles, distribution lists require cgo for now
  • Package ibmmq now includes the numeric #defines as a Go file, cmqc.go, for easier use
  • Removed "src/" prefix from tree in github repo
  • Removed need for buffer length parm on Put/Put1
  • Updated comments
  • Added MQINQ
  • Added MQItoString function for some maps of values to constant names

25 Jul 2016

  • Added functions to handle basic PCF creation and parsing
  • Added a monitor command for exporting MQ V9 queue manager data to Prometheus. See the README for more details

04 Aug 2016

  • Added a monitor command for exporting MQ data to InfluxDB. See the [README] (cmd/mq_influx/README.md) for more details
  • Restructured the monitoring code to put common material in the mqmetric package, called from the Influx and Prometheus monitors.

12 Aug 2016

  • Added a OpenTSDB monitor. See the README for more details.
  • Added a Collectd monitor. See the README for more details.
  • Added MQI MQCNO/MQCSP structures to support client connections and password authentication with MQCONNX.
  • Allow client-mode connections from the monitor programs
  • Added Grafana dashboards for the different monitors to show how to query them
  • Changed database password mechanism so that "exec" maintains the PID for MQ services

23 Aug 2016

  • Added a collector for Amazon AWS CloudWatch monitoring. See the README for more details.

17 Oct 2016

  • Added some Windows support. An example batch file is included in the mq_influx directory; changes would be needed to the MQSC script to call it. The other monitor programs can be supported with similar modifications.
  • Added a "getting started" section to this README.

07 Nov 2016

  • Added a collector that prints metrics in a simple JSON format. See the README for more details.
  • Fixed bug where freespace metrics were showing as non-integer bytes, not percentages

14 Dec 2016

  • Minor updates to this README for formatting
  • Removed xxx_CURRENT_LENGTH definitions from cmqc

10 Jan 2017

  • Added support for the MQCD and MQSCO structures to allow programmable client connectivity, without requiring a CCDT. See the clientconn sample program for an example of using the MQCD.
  • Moved sample programs into subdirectory

15 Feb 2017

  • API BREAKING CHANGE: The MQI verbs have been changed to return a single error indicator instead of two separate values. See mqitest.go for examples of how MQRC/MQCC codes can now be tested and extracted. This change makes the MQI implementation a bit more natural for Go environments.

25 Mar 2017

  • Added the metaPrefix option to the Prometheus monitor. This allows selection of non-default resources such as the MQ Bridge for Salesforce included in MQ 9.0.2.
