[Xymon] custom scripts for windows servers

Tue May 22 23:42:02 CEST 2018

What is loglevel set to in the bbwin section of bbwin.cfg?  The
documentation says the default is 0 for no log. 1 = errors, 2 = warnings, 3
= info, 4 = debug.

Hi

Our dev decided to create a groovy script since the tests it needs to do is
complex.

He created a small test script which I copied to the ext folder:

test.groovy

def file1 = new File('C:/Program Files (x86)/BBWin/tmp/test.txt')

file1.write 'Test message'

Added to externals block:

<externals>

                <setting name="timer" value="3m" />

                <setting name="logstimer" value="60s" />

                <load value="groovy test.groovy" timer="1m" />

                <!-- externals launch examples

                <load value="cscript mybbscript.vbs" />

                <load value="myexternal.exe" />

                <load value="cscript wlbs.vbs" timer="15m" />

                <load value="cluster.exe" timer="90s" /> -->

</externals>

I Also tried the full path to test.groovy.

Restarted the client, I even set the log on as from Local system to
Administrator.

The file “test.txt” is not created.

There’s no errors logged in the BBWin.log

How can I be sure BBwin is executing the script?

Groovy is installed. “C:\groovy-2.4.15\bin\groovy”

I am able to run the script from command prompt and the test.txt file is
created.

Kind regards

Hi Chris

BBWin or WinPSClient do not have a built in scripting language, they only
support scripts that the OS already knows how to run. This will depend on
what tools you have installed on your servers.

By default, Windows servers will definitely run VBScript (VBS) and most
newer versions (Windows Server 2008 onwards, Windows 7 onwards) will run
Powershell.

There are a number of script samples in BBWin in the externals folder and
for WinPSClient, the documentation is fairly complete in this area.

Both BBWin and WinPSClient can return data from any script if that script
writes a text file to the tmp folder (which is a subfolder of BBWin or
WinPSClient).

Below is a Powershell example of testing DNS lookup for google.com – this
is not necessarily the best way to test DNS, it is provided as a simple
example of an external script.

If this were saved as “google-dns.ps1”, and a SHA1 hash of the file
generated, it can be used with the WinPSClient by adding a line like this
to client-local.cfg – you do not need to replace the {script} with
anything, the client will do that:

external:everyscan:sync:http://<xymon
server>/PS_Updates/google-dns.ps1|SHA1|<sha1
value>|powershell.exe|-executionpolicy remotesigned -noprofile -file
"{script}"

Cheers

Good day all

Can someone please send links to example custom scripts for windows server.

We are mostly a Linux shop but have a few Windows servers. They are
monitored on xymon and it is currently a mix of BBwin and winpsclients.

My google skills has let me down as I could not find examples except for
bash script examples..

Does BBwin or winpsclient support groovy script or can I only use VBscript?

Kind regards
