Hello KS-Soft Team,
I read across the forum and searched for a lot of concepts, but I don't find an acceptable workaround for my problem.
I need 2 instances of the HostMonitor. One primary HM, which monitors my network and sends alerts, and an other (secondary) HM, which looks after the primary ones. If my primary installation of HM goes down, the backup HM accepts the work of monitoring and if my primary HM is running again, the secondary HM "goes to sleep".
That's not an issue. I have to install 2 instances of the HM on 2 various systems and furthermore I have to define one process test in every HM to monitor the other. Thus both run interdependently.
Now the problem for this solution:
I have to insert every test into the primary AND the secondary HM. At the moment there are almost 300 tests running. Ok, I could copy all *.hml, *.lst and *.ini files from one HM's folder to the other, but this only function properly, if the other ones isn't running. What's more, some parameters inside of the *ini files disagree. I also tested the Replicator, but this tool doesn't help my much.
I need a solution to set up 2 instances of the HM, that synchronise each other. Thus I insert a new test into my primary installation and the backup HM inserts this into its hierarchic structure.
The only one that could work, is to export all Tests (txt file) and import with this text file. But this doesn't work, if there are sub folders in the tree, that weren't created in the tree of the other HM. I had to write a script, that looks for the folders in the txt file and insert the "CreateFolder" command for every folder found in the file at the beginning of the txt file. Thus the imported file creates the hierarchic structure and inserts the tests.
Ok, it works, but I'm looking for a solid solution.
Any idea!?
Thank you for your efforts!

HowTo run 2 stand-alone, synchronised instances of HM

Probably, you may use following approach. You should setup 2nd instance of HostMonitor to monitor primary one. E.g. you may use TCP test to check RCI port (1054) or you may use "File Availability" test method to monitor reports or log files. When failure detected (e.g. primary HostMonitor does nor answer on RCI port), 2nd instance may send e-mail to admin and start HMS Script with single action (LoadTestList filename) to load primary list of tests. To make it work properly, you should select "Auto save TestList after any changes" option from "Autosave options" dropdown in "Preferences" tab of "Options" dialog for the first instance. After that you may use built-in "Scheduler" on the first HostMontior's instance to copy current test list to some network resource, accessible by second instance, on regular basis. In case of failure, second instance will be able to load fresh version of the tests list.
Additionally, you may load the test or tests, that checks when first instance cane up. When second instance detects the first instance is running, it should load initial tests list.

Good Morning Max (we got it a quarter to 8 am),
at first, great thanks you for your reply.
Until I wrote my topic, I also tested this variant. It is really simple to define a test, that starts the HMS script, loads the *.hml file and begins to do the job of the primary HM.
But there is still the problem with the synchronization. It is easy to transfer the test of the primary HM to the secondary one (via Export / Import or via LoadTestList), but what about the configuration? If a test uses a scheduler, which one is not defined in the backup HM, the test never runs. To copy the relevant HM files (*.ini, *.lst, etc.) is not a solution, because the HM needs these files on start up to know the RMAs, schedules and so on.
I got one alternative:
- define a test at the primary HM to copy the relevant files to the backup system
- place the *.hml file at a reachable (for both system) directory
- define a test at the secondary HM to look after the primary one and if this test becomes "Bad" starting a script that "LoadTestList" and execute a script to restart secondary HM
The backup HM should start with the last known *.hml file, which is located somewhere in the net and load all configurations and other lists (RMA, schedules, etc.), which was copied from primary HM's folder to backup HM's folder.
There is a need for clarification. I have to speak with the administration, which solution we aspire.
I was just looking for a tool or script to synchronize 2 stand-alone instances of HM, but this seems to be a topic for the "Wish List"
Thank you all the same!

Hello everyone!
I wish you great success with this project.
Here is my solution to solve this problem:
### At the backup system ###
Install HM the same way like at the primary system (as service!!!), but do not start the HostMon service.
Create 2 executable scripts. The first one to look after the primary HM and the second one to get all relevant files from the primary HM.
AutoIt is a nice scripting language (look at http://www.autoitscript.com/). It is free, easy to learn and got a great development environment.
Here is the AutoIt script to check HostMon service at the primary system. This script starts the backup HM, if the other system is down, or the HostMon service is not running:
The included "ServiceControl.au3" could be found at the website of AutoIt, or have a look here http://www.autoitscript.com/forum/index ... topic=6487
This is the AutoIt script to get all relevant files, which are needed (*.hml, *.ini, scripts written by oneself, and so on...). Thus the backup HM can use the current files:
With the development environment of AutoIt, you can convert the script to an *.exe file. To start and stop services admin permissions are needed. Thus it is meaningful to run the compiled script as windows service. Running as a service, it runs under "local system account". This account got these permissions.
You can use RunAsSrv (http://www.pirmasoft.de/runassvc.php) to install the two *.exe files as service.
If you want to see, what is happening, set the services "allow to interact with desktop".
Okay, that's it.
Have a nice day...
