All connection and monitoring settings have to be set in exporter_config.yaml file.
Below is an example of a filled configuration file with all possible fields:

Steps, that need to be taken to build the exporter:
- Download current repository.
- Install Maven.
- Go to mq-java-exporter root folder (where pom.xml is located) and run:
mvn package- After processing is completed, go to mq-java-exporter/target. lib directory and mq_exporter.jar should appear there.
Back to TOC.
To run exporter, lib directory (and all jars in it) and
mq_exporter.jar should be located in the same folder.
Back to TOC.
It is recommended way of running the exporter. Note: all commands
should be executed via MQ CLI. More info can be found here.
Define queue manager service with the following command:
DEFINE SERVICE(MQEXPORTER) CONTROL(QMGR) SERVTYPE(SERVER) +
STARTCMD('/opt/mqm/java/jre64/jre/bin/java') +
STARTARG('-Dlog4j.configurationFile=/opt/mq_exporter/log4j2.properties -jar /opt/mq_exporter/mq_exporter.jar /opt/mq_exporter/exporter_config.yaml') +
STOPCMD('/usr/bin/kill ' ) STOPARG(+MQ_SERVER_PID+) +
STDOUT('/opt/mq_exporter/mq_prometheus.out') +
STDERR('/opt/mq_exporter/mq_prometheus.out') +
DESCR('MQ exporter for Prometheus')
More information about this command can be found here.
To start exporter, execute the following command:
START SERVICE(MQEXPORTER)
To stop exporter, execute the following command:
STOP SERVICE(MQEXPORTER)
Back to TOC.
To run exporter execute the following command:
java -jar mq_exporter.jar /opt/mq_exporter/exporter_config.yamlThe only input parameter is the path to your configuration file.

All metrics have predefined structure: domain, subdomain, name, units:
- Domain - the first single-word prefix that represents a metric type. The examples of domain-level prefixes are: system, mq, mqobject and etc. More information can be found in "Domains and subdomains" section.
- Subdomain - second single-word prefix representation of a metric type. It provides more specific information about metric type and helps to differentiate metrics in a single domain. The examples of subdomain-level prefixes are: cpu, ram, put, subscribe, get and etc. More information can be found in "Domains and subdomains" section.
- Units - single-word suffix describing the metric's unit, in plural form. Note that an accumulating count has "total" as the first part of a suffix. The examples of unit suffixes are: percentage, messages, totalmessages and etc. More information can be found in "Units" section.
- Name - represents metric meaning. The examples of a metric name are: cpu_time, cpu_load_fifteen_minute_average, failed_mqget_count and etc. Note that the amount of words in a metric name can vary:

This section provides a description of metric units.
"Metric and label naming" article by Prometheus states that metrics "...should use base units (e.g. seconds, bytes, meters - not milliseconds, megabytes, kilometers)". There was an attempt to find a balance between MQ metrics and Prometheus metrics (according to the Prometheus conventions), but it was decided to change the metrics from MQ as little as possible, since some metrics do not fit the description in the article. Conversion of values for certain metrics can lead to a distortion of actual values (e.g. integer amount megabytes) and increasing in disk space, occupied by the metric. So the exporter has following list of units:
| Unit | Unit description |
| percentage | Shows % |
| megabytes | Shows amount of megabytes |
| files | Shows amount of files |
| bytes | Shows amount of bytes |
| microseconds | Shows amount of microseconds. |
| totalcalls | Shows amount of calls. An accumulating count has "total" as the first part of a suffix. |
| totalconnections | Shows amount of connections. An accumulating count has "total" as the first part of a suffix. |
| totalmessages | Shows amount of messages. An accumulating count has "total" as the first part of a suffix. |
| totalbytes | Shows amount of bytes. An accumulating count has "total" as the first part of a suffix. |
| totalbrowses | Shows amount of browses. An accumulating count has "total" as the first part of a suffix. |
| subscriptions | Shows amount of subscriptions. |
| totalattempts | Shows amount of attempts. An accumulating count has "total" as the first part of a suffix. |
| totalqueues | Shows amount of queues. An accumulating count has "total" as the first part of a suffix. |
| messages | Shows amount of messages. |
| untyped | If it's not obvious, what the type of metric is, then this type is used (for example, it is used, to reflect system's load average and LISTENER\CHANNEL status codes). |

This section provides a description of metrics of queues, channels and listeners that are collected via sending direct PCF commands to queue manager.
| Prometheus metric name | Metric type | Short description |
| mqobject_queue_queue_max_depth_messages | gauge | Shows maximum number of messages that are allowed on the queue. |
| mqobject_queue_queue_fill_percentage | gauge | Shows queue fill percentage. |
| mqobject_queue_queue_get_inhibited_untyped | gauge | Returns 0 if get is allowed and 1 otherwise. |
| mqobject_queue_queue_put_inhibited_untyped | gauge | Returns 0 if put is allowed and 1 otherwise. |
| mqobject_channel_channel_status_untyped | gauge | Shows current channel status. Mapping of channel statuses to prometheus metric values can be found here. |
| mqobject_listener_listener_status_untyped | gauge | Shows current listener status. Mapping of listener statuses to prometheus metric values can be found here. |

This section provides a mapping between MQ channel statuses and metric values, that are sent to Prometheus.
| MQ channel status code | Prometheus metric value |
| RUNNING | 100 |
| REQUESTING | 90 |
| PAUSED | 80 |
| BINDING | 70 |
| STARTING | 60 |
| INITIALIZING | 50 |
| SWITCHING | 40 |
| STOPPING | 30 |
| RETRYING | 20 |
| STOPPED | 10 |
| INACTIVE | 0 |
Note: If channel has status INACTIVE, there is no way to retrieve it's status by PCF command (because technically channel has no status) and MQRCCF_CHL_STATUS_NOT_FOUND will be returned by queue manager. Since INACTIVE status of the channel is the most frequent reason for receiving such an error, the exporter interprets it as INACTIVE status of the channel.

This section provides a mapping between MQ listener statuses and metric values, that are sent to Prometheus.
| MQ listener status code | Prometheus metric value |
| RUNNING | 100 |
| STARTING | 75 |
| STOPPING | 50 |
| STOPPED | 0 |

The following are known issues and may affect your use of exporter.
Metric mq_ram_ram_total_estimate_megabytes may contain negative values. #62
This problem is related to this IBM APAR. The problem appeared during testing the exporter on MQ ver. 9.0.1.0. We could not reproduce this problem on MQ ver. 9.1.0.1 (this version includes fix for APAR above). Unfortunately, there is no way to fix this problem on the exporter side and the only option is to wait for the fix from IBM for MQ ver. 9.0.x.x.
