Service Monitor Script - Perl for Windows Services

#1

Author: MikeD Business_Intelligence@hotmail.com
Author notes: XiServiceMonitor_Guide.txt General guide for setting up and running the script.
Thread: Service Monitoring
Platform: Windows 2003 Should be backward & forward compatible as no specific 2003 inclusions were used.
Version: 0.1 Updates will be available on request or per any onsite modifications.
Code: XiServiceMonitor.pl Perl Script with embedded comments.

This Perl script will read a list of services to be monitored, and then attempt a restart on any stopped service(s).
If the failed service won’t restart - all services in the list will be stopped.

Note: The script should be able to handle any windows service monitoring by simply changing the list of services that is read in from the text file i.e. my requirement was to develop something for XI so the input file contains a list of all the BOE XI and EPM services.

I have included a command in the guide as to how to print out all the services running on your machine.
One cannot use the Description name that you see in the Services monitor.
By running the command mentioned, you can select which service name(s) to place in the list.
i.e. I have not tested this on any previous BO versions, but I did some offsite testing on a few DB2 and laptop services, which worked just fine, so it is proved to be flexible re any services.

The zip includes:
[list]
XiServiceMonitor_Guide.txt General guide for setting up and running the script.
XiServiceList.txt List of services to be monitored.
XiServiceMonitor.pl Perl Script with embedded comments.
XiServiceMonitor.log Example of logged actions.
Komodo_screenshot.rtf Screenshot for testing/running the script with Komodo - this IDE handles perl syntax and has smart prompts for errors etc.
[/list]

If you have the environment variables set as per the guide, you will be able to start the script by double clicking it - or running it via a DOS command window once you have set the directory path to the perl.exe i.e. c:\Perl\bin.
The loop is set via a sleep(300) cycle (5 minutes) - as per the embedded script comments - this can obviously be changed to a cycle of your own choosing.

At this point in time, I have yet to be able to get this script to run as a service :hb:
I have listed all the methods that I tried by including the relevant site links in the guide.
i.e. According to all my forum hopping, it apparently is possible, so hopefully if anyone here decides to use this and manages to get that right - please contact me :stuck_out_tongue:

Has there been any modifications to this pearl script since it’s posting. I am also facing the challenge of the identifying hung services. They show that they are running but they are non responsive.

Nope - it works, but I left the BO realm to dabble in the Cognos realm, so did not get a chance to revisit the creation of the script as a service i.e. the actual method works re constantly checking the service status.
Methinx you might have an issue re the status check in that the script uses a windows method to get the status of the service, so you will have to confirm whether the hung state can be identified via the windows service status - maybe the PENDING state?

Let me know if you need any further info re the script etc.

Being that BO 3.1 Servers & Services have now been “Virtualized” (ie. all BO Services & Servers no longer show up as a “Windows Service”), will this script work with BO 3.1? If not, do you (or anyone else) know of a way to monitor & alert when a BO virtualized Service/Server goes down (and to then bring it back up)?

Thanks.

Nope - this script was windows service specific but I am looking into a replacement that monitors processes etc

The Guide mentions:
Make sure to include the following in the Path System Variable:
C:\Program Files\ActiveState Perl Dev Kit 6.0\bin;C:\Perl\bin;

The perl/w executable will kick off from bin and should automatically refer to C:\Perl\lib\ - so depending on your installation setup you can place them in the perl library (lib).

Thanks Mike :slight_smile: for quick reply.

As per XiServiceMonitor_Guide I have installed Active perl and Komodo_ide and also I have created variables also(one i doubt on this … can I create variable name for Server or Laptop i.e Variable = Server?)
and the hostname in text file also.

after I am not understood remaining step could you please let me some details steps on this On this.
because I didn’t get Komdo_sreenshot as you mentioned I try to open the Komodo IDe but its not opening.

and where I can place Xi service.txt, XiserviceMonitor.pl and log files.

I am very poor on Admin side.

Many thanks for your help… :slight_smile: , actually I am very curious to how they works.

Many thanks

Kala

Yes - you can use a variable for the server.
Place all files in the Perl Library.
No - you don’t have to use Komodo - any IDE that has a Perl module can be used e.g. Eclipse.
You only need an IDE if you want to run the script step by step to see what it does. The alternative is to use display comments.

Hi Mike,

is this script work for unix environment. Please let me know.

Thanks,
Venkat

Nope - Unix uses daemons and windows uses services i.e. the perl script uses a windows function Win32::Service::GetStatus to evaluate the status of the services.

Thanks for reply Mike. is there any script like this for unix?

I have not had a chance to rework this into the Unix environment as I’m rather considering upgrading this to handle the XI 3 environment which uses processes as opposed to services.
I’m sure it could be scripted pretty easily using a variety of scripting languages - best stick to the shell script that your OS uses.

How’s the XI 3.1 upgrade for this coming? Any idea when you might release it?
