Percona-qan-api not starting in docker container

Percona Monitoring and Management (PMM) PMM 1.x

I followed the guide for setting up a docker container here: [url]https://www.percona.com/doc/percona-server/LATEST/installation/docker.html[/url]

After setting up, I proceeded to set up clients and the metrics monitor is working fine. However, the query monitor is not. The output of

pmm-admin check-network

shows that the Query Analytics API is down.

After delving into the docker container itself, and trying to start

/usr/share/percona-qan-api

manually, I get the following output. I found the below command by running ps ax.

I’m not sure what to do from this point, as I don’t seem to be able to start the qan api in the docker container. The container has more than enough space, and this is a very recent clean install.

Apologies, this is the guide I followed: [url]Percona Monitoring and Management

Hello there, thank you for posting. Hopefully the PMM team will be able to take a look at your question very soon, but in the meanwhile just in case this helps you find the solution, I thought I would share a couple of blog posts for you to run through on troubleshooting and installation:

Thanks Lorraine - I had a look at these and they helped confirm that the qan-api is down, but unfortunately there’s no information on why it wouldn’t be working in the container.

Makeshift , What version of Pmm Client and Servers do you using?

6

roma.novikov The server version is the docker container percona/pmm-server:latest, and it was grabbed yesterday, so it’s 1.7.0

The client version is 1.7.0, according to pmm-admin --version.

Since I didn’t get a reply, I tried 1.6.1 instead and that works fine. Pretty sure the latest version of your docker container doesn’t work.

Makeshift , this is strange. the docker was supposed to work in any cases, especially in a clean install.

Can you also check and run the tool from this tutorial [url]https://www.percona.com/blog/2016/11/01/percona-monitoring-and-management-pmm-information-script/[/url] and collect additional data. Thanks
