Using the rotten old version of Chrome on the corporate desktops its OK until I look at trace details then it all goes black and blank. I can probably a reasonably new version installed but it would be good to know if Edge/Chrome/Firefox manage to handle the UI before I ask for something :-)

I look at trace details then it all goes black and blank.@Robert Smith this used to occur when spans are missing and a complete trace is not built. In

screenshot and the response of API call at that page would be very helpful. Response of api call can be found at network tab after inspect element

07/21/2022, 8:27 AMThese show the traces screen I was in and then the blank one after clicking any of the traces shown. After about 1/2 second some stuff did flash up on the screen but too quickly for me to register any content the screen turned black as show. This behaviour is repeatable and happens every time for any trace I select.

07/21/2022, 8:30 AMI'm not sure how to access the API call info as my screen is black showing nothing at that point. I have clicked 'refresh' a few time to read the message flashing up and it is as follows:

B) The lefthand menu pane appears along with a black main pane showing at the top only Home/Trace/ and then some long number in white. Then it immediately goes completely black for the whole window.

07/21/2022, 8:46 AMFunnily enough when I went back to a non-blank prior screen there was a green tick, but 5 seconds later that cjhanged back to the red triangle. (P.S. I had a quick go at installing Loom but failed on that - our windows admins do stop us trying to install anything on the desktops).

07/21/2022, 8:51 AMI just went hunting for log files and found just those in signoz/deploy/docker/clickhouse-setup/data/clickhouse/data/system but when I went there they were all links to stuff in /var/lib/clickhouse/store/ but there is no such location so the links are all bad. This doesn't seem good ...

07/21/2022, 9:00 AMCan you share the steps you followed to set up SigNoz cluster?

Robert Smith
07/21/2022, 9:03 AMSure. It is just a single node set up for a POC where I have just followed the online docker-standalone install process as here https://signoz.io/docs/install/docker/ where I didn't choose a specific version but installed from main.
Robert Smith
07/21/2022, 9:04 AMah, didn't mean to have that screenshot showing. sorry
Robert Smith
07/21/2022, 9:16 AMThis may be my fault. Reading troubleshooting & its links to pre-reqs I get the idea that trying to run this on a small 1G VM is not going to fly. Is the suggested 4G memory sufficient for small scale trial use or, as I'll have to provision another VM, should I allocate more?

yes.. 1G can show unexpected errors
Ankit Nayan
07/21/2022, 9:18 AM
2CPUs and 4GB RAM for a PoC and scaling as needed

Robert Smith
07/21/2022, 9:27 AMOK, thanks for your help. I'll try turning the metric retention down to see if that makes it usable first then warn the bean counters that I'm about to spnd some money.

I'll try turning the metric retention downmetrics do not have any relation to trace detail page where you are seeing errors

Robert Smith
07/21/2022, 10:25 AMBoth turning metric retention down and increasing existing VM size to 2xcpu and 16G ram has not changed the behaviour. Still not finding the trace and giving a blank screen - might this be something to do with missing /var/lib/clickhouse/store/? Anything left to do now rather than uninstall and reinstall, and if so should I install from main or a specific version?
Robert Smith
07/21/2022, 11:05 AMDeleting and reinstalling everything from scratch still hasn't changed the problem. Unless this is a reproducible problem elsewhere with current main version I'm tempted to go back to my original idea that it might be the very old version of Chrome that we have installed on the desktops.
Robert Smith
07/21/2022, 1:23 PMResolved: Thanks for the help guys. Problem was in the end the old browser so as a data point Chrome v79.x fails but Chrome v88.x seems fine.
