One of Visios needs to load consistently on /monitoring; most times, this results in errors. Sometimes this stalls on 'Loading' and results in 'The request timed out' error. A few times, it displayed tabs, but clicking on them resulted in 'Could not retrieve the image for the Visual Overview'.
The Cube client is working consistently but needs the monitoring App. We are using DMA itself for testing, and the frequency of errors increases when the monitoring app is used outside DMA. DMA has enough resources, CPU usage is always under 10%, and there is plenty of memory space.
Where can I find logs for this monitoring page load? Appreciate if there are any suggestions on best way to debug this issue.
Hi Srikanth,
I would suggest to have a look in the different SLHelper log files in C:\Skyline DataMiner\Logging
Thanks Jens.
There is only SLHelperWrapper.txt in the logging directory. It doesn’t have entries relate to Visio or monitoring at the time of page loading.
However there are following entries in SLErrors.txt and SLProtobufSerialization.txt files at the time of page loading. Please note that the page does load Visio occasionally. Does this any clue on what the issue might be?
