Regular failures in System Monitor

Mon, 26 Jan 2026 18:19:17 GMT

Hello

My company has a system monitor in place and it seems to fail quite regularly. It has only started failing regularly in the last few weeks. When it is ran manually it shows that the Task Execution History file is being accessed by another application.

I'm pretty sure our problem is that there is another Qlikview application that is running continuously and it only takes around 4-10 seconds on average to run. My team think that the log file we are accessing is being updated at the time our System Monitor is being ran, therefore it is failing.

Has anyone else come across a similar problem in their time when using a System Monitor?

Thanks

Stuart

Hi,

It could happen when you have huge logs to read from.

By the way did you try the latest version below.

Would there be any way of reducing the log files we read from?

I've saw that System Monitor before but the company I work with have had one developed in house.

Thanks

Hi,

You can find logs in below path

C:\ProgramData\QlikTech\QlikViewServer

C:\ProgramData\QlikTech\DistributionService\1\Log.

System monitor is easy to configure even.

I have the same issue that you are describing. There seems to (sometimes) be a conflict over the Task Execution History files here as well. We use an application for monitoring that we have developed ourselves, and it reads these files.

I am thinking that it somewhat must be bound to happen when reading these files regularly, as they are updated every time a task is reloaded.

Were you able to figure out anything else?

Hi,

You may try by scheduling dependent tasks.

Hi Ashfaq,

Thank you for your suggestion.

Tasks are already scheduled as dependent, but we are experiencing conflicts between various different applications, so it would not be very practical to try to schedule x number of applications.

Hi you can split task and place them in a order they required in a separate qvw file and schedule accordingly.

For any change do you have antivirus in the publisher machine, if you do make sure to exclude the antivirus scanning of the Qlikview folders. This could be intrusive as well.

Sorry for the late reply for anyone who has been following the thread. I have been on holidays.

My team made a batch file to copy the log files we are pointing our Sytem Monitor to. We only load the System Monitor once a day so the copy is made just before the System Monitor runs on it's normal schedule. By doing this we are not running off the 'LIVE' log files and there haven't been as many failures since we have done this.

Hope this helps

Stuart
