AppDynamics Monitoring Extension for use with IBM Websphere MessageBroker or IIB

Use case

The IBM Integration Bus, formerly known as the IBM WebSphere Message Broker Family, provides a variety of options for implementing a universal integration foundation based on an enterprise service bus (ESB). Implementations help to enable connectivity and transformation in heterogeneous IT environments for businesses of any size, in any industry and covering a range of platforms.

AppDynamics officially supports an IIB Agent to instrument IIB applications. This extension just collects resource and message flow stats from an application but wouldn't instrument the application. Please make sure to use the right product for your use case.

Metrics Provided

This extension extracts resource and message flow statistics. The list of metrics that it extracts can be found here:
Resource Statistics
Flow Statistics

Prerequisites

1. Before the extension is installed, the prerequisites mentioned here need to be met. Please do not proceed with the extension installation if the specified prerequisites are not met.
2. This extension requires a AppDynamics Java Machine Agent installed and running.
3. If this extension is configured for Client transport type (more on that later), please make sure the MQ's host and port is accessible.
4. If this extension is configured for Bindings transport type (more on that later), admin level credentials to the queue manager would be needed. If the hosting OS for IBM MQ is Windows, Windows user credentials will be needed.

Dependencies

This extension requires the IBM MQ JMS client classes. Refer to the IBM documentation for the specific jars.
For IBM MQ 8.0 and above, it depends on the following jars:

com.ibm.mq.allclient.jar
com.ibm.mq.traceControl.jar
fscontext.jar
jms.jar
providerutil.jar

For previous versions,

com.ibm.mqjms.jar
jms.jar

This extension works for Windows, Unix as well as AIX.

Installation

To install the extension, extract the zip file to /monitors/. (IBM doesn't recommend copying the IBM jar files into other file locations.In fact, from MQ version 8.0 onwards, IBM restricts the jars that can be copied. See here.)

If you are planning to use it in Bindings mode, please make sure that based on your OS, the right paths containing the IBM MQ and JMS jars are specified in the `appd-message-broker-monitor.sh` or `appd-message-broker-monitor.bat`.
For eg. if the IBM jar files exist in opt/mqm/java/lib directory, update the `appd-message-broker-monitor.sh` file as below. (Take a note of two places where you may have to edit the path in the script file)

#!/bin/bash

#Passing machine agent process id to java process.
../../jre/bin/java -cp "./*:../../machineagent.jar:/opt/mqm/java/lib/*" -Djava.library.path=/opt/mqm/java/lib64 -Dlog4j.configuration=file:./log4j.xml -Dextension.configuration=./monitors/WMBMonitor/config.yml com.appdynamics.extensions.wmb.WMBMonitor $PPID

exit $?

If you are planning to use it in Client mode, please download the right version of IBM MQ Client on that remote server and obtain the above mentioned IBM jars from there and place it in the directory and just like above change the paths in the `appd-message-broker-monitor.sh` or `appd-message-broker-monitor.bat` files.

There are two configurations needed:

1. On the WebSphere Message Broker
   To get resource statistics from the broker, first you will have to enable the resource statistics on WMB (WebSphere Message Broker).
   
   1. You can run "mqsichangeresourcestats" by running it in IBM Integration Console (in WMB 9.0) or IBM WMB Command Console (in previous versions). A sample command can be

      mqsichangeresourcestats BrokerA -c active -e default 
                   
          where
          BrokerA -> the broker name
          default -> the execution group / integration server
      

      Please follow the below documentation to get more familiar with the mqsichangeresourcestats
   2. To get message flow statistics, you have to enable them for a particular application / message flow:
      

      mqsichangeflowstats BrokerA -e default -k application -f messageflow -s -o xml -c active
      
          where
          BrokerA -> the broker name
          default -> the execution group / integration server
          application -> the application name
          messageflow -> the name of the message flow
      

      Please follow the below documentation to get more familiar with the mqsichangeflowstats
   Once you have started the statistic collection, you can confirm it by viewing the statistics as follows
   

    - Open IBM WebSphere MQ Explorer
    - Click on Integration Node i.e. Broker Name
    - Right click on the execution group which you want statistics for and view resource statistics.
   

   Alternatively you can verify that the collection of statistics is enabled using the Broker's Web Interface.
   The resource metrics get published every 20 seconds to a topic. For the above command, the statistics will get published on this topic $SYS/Broker/BrokerA/ResourceStatistics/default. Similarly, snapshot statistics for message flows get published every 20 seconds to the corresponding topic $SYS/Broker/+/StatisticsAccounting/SnapShot/application/messageflow.
   For more details, please follow the IBM documentation
   The extension subscribes to a particular topic in a queue manager's queue. Please confirm that you have all of the following in the IBM WebSphere MQ explorer:
   1. Queue Manager.
   2. A TCP Listener on some port controlled/managed by Queue Manager. This port will be the port which we will use to subscribe to the statistics from the extension.
   If the queue manager and/or TCP listener is not present, please create them.


2. On the appdynamics extension You can run this extension in Client or Bindings mode. In `Bindings` mode the extension needs to be installed on the same box as the MQ Server. In Client mode the extension needs to be remote and should have the access to the MQ Server.
   
   Edit the file config.yml located at <MachineAgent_Dir>/monitors/WMBMonitor The metricPrefix of the extension has to be configured as specified here. Please make sure that the right metricPrefix is chosen based on your machine agent deployment, otherwise this could lead to metrics not being visible in the controller.

Performance Overhead

There may be a performance overhead on activating resource and flow stats in your IIB environment. Here is what IBM has documented about the performance impact.

Support for AIX

This extension works on AIX if you point to

 <file os-type="aix">appd-message-broker-monitor.sh</file> 

in the monitor.xml and change the appd-message-broker-monitor.sh and process_checker.sh files to using korn shell.

Metric Properties

You may see some metrics as an ever increasing counter. Sometimes that is helpful but most of the times you may just want to see the change in that minute for a particular metric. We let you configure that in the config.yml for each metric.

          - type: "TCPIPClientNodes"
              identifiers: ["summary"]
              include:
                - OpenConnections: "OpenConnections" #The current number of open connections
                - MessagesReceived: "MessagesReceived" #The total number of messages received (by TCPIPClientInput or TCPIPClientReceive nodes)
                  delta: true
                  metricType: "SUM SUM INDIVIDUAL"
                - MessagesSent : "MessagesSent" #The total number of messages sent (by TCPIPClientOutput nodes)
                  delta: true
                  metricType: "SUM SUM INDIVIDUAL"
                - BytesSent : "BytesSent" #The total amount of data sent (by TCPIPClientOutput nodes), excluding SSL wrappers.
                  delta: true
                  metricType: "SUM SUM INDIVIDUAL"
                - BytesReceived: "BytesReceived"  #The total amount of data received (by TCPIPClientInput or TCPIPClientReceive nodes),  excluding SSL wrappers.
                  delta: true
                  metricType: "SUM SUM INDIVIDUAL"
                - FailedConnections : "FailedConnections"  #The total number of attempted connections that failed since the last integration server restarts.
                  delta: true
                  metricType: "SUM SUM INDIVIDUAL"

In the above configuration, for MessagesReceived,MessagesSent,BytesSent,BytesReceived,FailedConnections, we have configured two properties delta and metricType.
delta - For each metric that has delta: true, the extension calculates a difference between the current and previous value and reports the difference. Default value for delta: false
metricType - It let's you define the metric qualifiers for the particular metric.
The format is "(Aggregation Qualifier) (Time Roll Up Qualifier) (Cluster Roll Up Qualifier)". To know more about these qualifiers, please visit this link

 In the above example, metricType: "SUM SUM INDIVIDUAL", means
   Aggregation Qualifier = SUM
   Time Roll Up Qualifier = SUM
   Cluster Roll Up Qualifier = INDIVIDUAL.

Extensions Workbench

Workbench is an inbuilt feature provided with each extension in order to assist you to fine tune the extension setup before you actually deploy it on the controller. Please review the following document on How to use the Extensions WorkBench

Troubleshooting

1. Please look at the troubleshooting document and make sure that everything is followed correctly.
2. Verify Machine Agent Data: Please start the Machine Agent without the extension and make sure that it reports data. Verify that the machine agent status is UP and it is reporting Hardware Metrics.
3. config.yml: Validate the file here
4. MQ Version incompatibilities : In case of any jar incompatibility issue, the rule of thumb is to use the jars from MQ version 8.0.
5. Metric Limit: Please start the machine agent with the argument -Dappdynamics.agent.maxMetrics=5000 if there is a metric limit reached error in the logs. If you don't see the expected metrics, this could be the cause.
6. Check Logs: There could be some obvious errors in the machine agent logs. Please take a look.
7. The config cannot be null error.
This usually happens when on a windows machine in monitor.xml you give config.yml file path with linux file path separator /. Use Windows file path separator \ e.g. monitors\MQMonitor\config.yaml. For Windows, please specify the complete path.
8. Please confirm whether the resourcestats and flowstats were enabled for the queue manager and the listener port is up.
9. Please follow the steps listed in this troubleshooting-document in order to troubleshoot your issue. These are a set of common issues that customers might have faced during the installation of the extension. If these don't solve your issue, please follow the last step on the troubleshooting-document to contact the support team.

Support Tickets

If after going through the Troubleshooting Document you have not been able to get your extension working, please file a ticket and add the following information.

Please provide the following in order for us to assist you better.

1. Stop the running machine agent .
2. Delete all existing logs under <MachineAgent>/logs.
3. Please enable debug logging by editing the file <MachineAgent>/conf/logging/log4j.xml. Change the level value of the following <logger> elements to debug.
   • <logger name="com.singularity">
   • <logger name="com.appdynamics">
4. Start the machine agent and please let it run for 10 mins. Then zip and upload all the logs in the directory <MachineAgent>/logs/*.
5. Attach the zipped <MachineAgent>/conf/* directory here.
6. Attach the zipped <MachineAgent>/monitors/ExtensionFolderYouAreHavingIssuesWith directory here .

For any support related questions, you can also contact help@appdynamics.com.
