Introduction

The monitoring scripts available with EntireX allow you to define your environment, to monitor it and to define actions in case of an error. Although the scripts are installed and run on Microsoft Windows, you can monitor your EntireX environment that is running on any other operating system. You can specify any broker accessible in the network, for example one running under z/OS. The scripts can be used with brokers of any supported EntireX version.


Getting Started

After installing EntireX on Windows you can find the shortcut to the monitoring scripts under your installation name > Administation.

Monitoring your EntireX Components (Snapshot)

Choose Option 1 from the EntireX Monitoring Scripts menu for an overview of the specified broker and registered services.

  • For the specified broker you see:

    • information where the broker is running

    • license information

    • some basic settings

  • For the registered services you see:

    • the class/server/service to identify the service

    • for each service, basic KPIs such as number of active replicates (active server instances)

    • maximum of pending parallel conversations

    • number of times all server instances were busy

In addition to this menu option, you can also call this function using a script. See Show Broker and Registered Services under EntireX Monitoring Scripts for command syntax and more information.

Note:
This option provides a snapshot of your current environment. The script runs once only and then terminates. You can also monitor your EntireX components over time. graphics/toc_closed.png More info

End of overview

Monitoring your EntireX Components over Time

The options described here monitor your EntireX components over a period of time. The scripts write basic KPIs to a CSV file. By default the CSV files are written to folder My Documents/Software AG/EntireX and are updated with the latest information, by default every 60 seconds. The scripts run until they are canceled. You can change the defaults with Option 6 from the EntireX Monitoring Scripts menu. See also Default Handling under Monitoring EntireX Components for more information.

In addition to the menu options described here, you can also call the functions using a script. See Monitoring EntireX Components under EntireX Monitoring Scripts for command syntax and more information.

Note:
You can also create a one-off snapshot of your environment.graphics/toc_closed.png More info

Monitor Broker

The CSV file for Option 2 Monitor Broker shows the following information:

  • time when the report was taken

  • time (in seconds) the broker was running (uptime)

  • number of active workers, servers, services and clients

  • allocated memory

  • high watermarks (HWMs) for servers, clients, conversations and memory

Sample output:

graphics/scripts_monitor-time_broker.png

In addition to the menu option described here, you can also call this function using a script. See Monitoring Broker under Monitoring EntireX Components for command syntax and more information.

Monitor Services

The CSV file for Option 3 Monitor Services shows the following information:

  • time when the report was taken

  • for each service that matches the selection: the class/server/service, which identifies the service

  • number of active servers providing this service

  • number of requests for this service

  • and information about the conversations

The server busy (count) is the number of times an incoming request had to wait because all instances of the server were busy. A high number (in relation to the total number of requests) may indicate that more replicates could help to improve the performance.

Sample output:

graphics/scripts_monitor-time_services.png

In addition to the menu option described here, you can also call this function using a script. See Monitoring Services under EntireX Monitoring Scripts for command syntax and more information.

Monitor Clients

The CSV file for Option 4 Monitor Clients shows the following information:

  • time when the report was taken

  • for each active client: the user ID, token, unique ID that identifies the client

  • status (waiting or not waiting)

  • start time of the client

  • host name where the client is running

  • information about the application

Sample output:

graphics/scripts_monitor-time_clients.png

In addition to the menu option described here, you can also call this function using a script. See Monitoring Clients under EntireX Monitoring Scripts for command syntax and more information.

Monitoring your EntireX Environment over Time

In this scenario you have an EntireX production environment with a broker and RPC or ACI servers that you want to monitor. You also want to receive notifications when a component of your environment goes down and is no longer available.

To do this, you can use the monitoring scripts available with EntireX. They allow you to define your environment, to monitor it and to define actions in case of an error. Although the scripts are installed and run on Microsoft Windows, you can monitor your EntireX environment that is running on any other operating system.

Use the options offered in the menu of the monitoring scripts to define and to monitor your environment.

Defining your Environment

Choose Option 7 Define your Environment to define your environment. This opens an editor with a sample definition of an environment. Adjust this definition to your needs.

Here you see an example of a basic environment:

ENVIRONMENT MyProductionServers
ERROREXIT handle_error.bat
BROKER myProductionBroker localhost:1971
@rem Example of a definition of an RPC Service
RPCSERVICE myRPCServer RPC SRV1 CALLNAT
@rem Example of a definition of an ACI Service
SERVICE myACIServer ACLASS ASERVER ASERVICE

An environment is defined by the keyword ENVIRONMENT, which you can define with a meaningful name. You need to define the following for this environment:

  • a user-written exit to handle outages

  • the broker

  • ACI or RPC services

Note:
The broker does not have to be running on the local PC; it can run anywhere in your network (as long as it is accessible from the PC where the monitoring script is running).

Use the keyword ERROREXIT to define your own error routine (a batch file) that is called in case of an outage. The batch file has to be in the PATH so that the monitoring script can call it. The error exit is called in case of an outage and provides information on the component (Broker or Server) that caused the error. File handle_error.bat is provided as an example. Adjust the error exit to your needs (for example send a notification in case of an outage).

Use the keyword BROKER followed by your logical name of the broker and the broker ID to define the broker to be monitored. See the provided sample environment for examples of how to specify user ID and the file containing the encrypted password if your broker is running with EntireX Security (see Using an Encrypted Password).

Use the keyword RPCSERVICE (for an RPC server) or SERVICE (for an ACI service) followed by your logical name and the class, server and service to define the server(s) to be monitored. You can define multiple servers. Example:

RPCSERVICE myCICSRPCServer RPC CICSSRV CALLNAT
@rem my CICS RPC Server
RPCSERVICE myBATCHRPCServer RPC BATCHSRV CALLNAT
@rem my Batch RPC Server

In this case the monitoring script will first check if the RPC Server for CICS can be called. Secondly it will check the availability of the RPC Server for Batch.

The definition of the environment is stored under My Documents/ Software AG/EntireX.

Monitoring your Environment

Choose Option 8 Monitor your Environment to start monitoring the environment you defined in the previous step. During execution, the definition of the environment will be passed.

  • Keyword BROKER checks if the defined broker can be accessed.

  • Keyword SERVICE checks if the defined (ACI) service is registered with the broker.

  • Keyword RPCSERVICE defines an RPC server. During execution this service will be "pinged" using the RPC ping command, which checks if the defined service can be called.

If an outage or error occurs, the error exit you wrote is called.

The environment check is repeated after a specified time (default is 60 seconds).

The technical basis for all these checks is the command-line utility etbinfo. Full details are provided under etbinfo in the Windows Administration documentation.

Handling Outages

If the check of a component in your environment (BROKER, SERVICE or RPCSERVICE) fails, the specified ERROREXIT is called and provides the following information:

  • the object (BROKER or SERVICE)

  • error number and error text returned by etbinfo

  • environment name

  • broker name and broker ID

  • if a service fails, the name, class, server and service

If an outage occurs, you can use this information to send a notification about the checked environment (using your defined environment name) and the component (broker or service) that is not available. Or you can try to automatically restart the component that is down.

Changing the Current Broker

Start of instruction setTo change the current broker for your current session

  • Choose option 5 from the EntireX Monitoring Scripts menu, "Change current Broker (this session only)". This changes the current broker ID used for executing the monitoring scripts in this session.

    If you restart the script, the broker ID will be (re)set to the default value.

Start of instruction setTo change the current broker permanently

  • Choose option 6 from the EntireX Monitoring Scripts menu, "Edit Broker and other Defaults (persistent)".

    Or:
    Run command edit_user_specific_monitor_defaults.bat in the EntireX bin directory.

    See Default Handling.

Script Menu Options

The following table lists the menu options and gives the corresponding command-line script.

Option Description Corresponding Script Note
1 Show Broker and registered Services. Displays information on the current broker and its registered services. graphics/toc_closed.png More info entirex_overview.bat  
2 Monitor Broker. Monitors the current broker. graphics/toc_closed.png More info monitor_broker_to_csv.bat Output for these three monitoring scripts is written to a CSV file (comma-separated values), which you can view, for example, with a spreadsheet tool.
3 Monitor Services. Monitors services registered to the current broker. graphics/toc_closed.png More info monitor_service_to_csv.bat
4 Monitor Clients. Monitors clients registered to the current broker. graphics/toc_closed.png More info monitor_client_to_csv.bat
5 Change Current Broker. Changes the broker used in the various scripts for this session only.   When the session is restarted, this value reverts to the default.
6 Edit Broker and other Defaults. You can modify defaults for Broker ID, timeout values and output files. graphics/toc_closed.png More info edit_user_specific_monitor_defaults.bat  
7 Define your Environment. You can define the environment (list of broker and registered services) you want to monitor. graphics/toc_closed.png More info edit_user_specific_environment_definition.bat  
8 Monitor your Environment (defined with option 7). graphics/toc_closed.png More info monitor_environment.bat  
9 Open New Command Window (in command-line script directory).   This enables you to start the scripts with your parameters.
0 Exit.   Exits the menu. If you changed the current broker with Option 5, this will revert to the default value. Monitoring scripts that write to CSV files running in a separate command window continue to run.

Using an Encrypted Password

You can encrypt a password and store this in a file. Specify this file instead of a cleartext password when you call a secure broker.

Note:
We strongly recommend that your cleartext password is longer than 16 characters.

Start of instruction setTo encrypt a password

  1. Enter the command:

    etbnattr --echo_password_only -w clear_text_password 
    The encrypted password is written to stdout.
  2. Copy the password value to an empty file. (Ignore the prefix KEY-PASSWD-ENCRYPTED:.)

See also:

  • Using an Encrypted Password in the Windows Administration documentation

  • Monitoring Broker under Monitoring EntireX Components for a sample script using an encrypted password

  • Note under Default Handling if your default settings file was created with a previous version of EntireX that did not support password encryption.
