Memgraph-lab doesn't display logs from memgraph-platform

[ValeriiaNesterova]

I am running 2 helm charts: one for memgraph-platform (memgraph/memgraph-platform:latest docker image) and second for memgraph (memgraph/memgraph:latest)

When I open UI and go to "Logs" section I see the message : "Logs are not available. Make sure port 7444 is open on your Memgraph."

The port 7444 is opened on Kubernetes side. I have service with this port and added it to pod itself. This is what I get when I check the connection from pod: root@memgraph-lab-0:/# nc -vz memgraph 7444 Connection to memgraph (10.100.37.25) 7444 port [tcp/*] succeeded!

Do I need to add anything to configuration? Now I have this:
memgraphConfig:

• "--also-log-to-stderr=true"
• "--data-directory=/var/lib/memgraph/"
• "--log-file=/var/log/memgraph/memgraph.log"
• "--log-level=DEBUG"
• "--memory-limit=4096"
• "--memory-warning-threshold=1024"
• "--query-max-plans=1000"
• "--storage-gc-cycle-sec=30"
• "--storage-properties-on-edges=true"
• "--storage-recover-on-startup=true"
• "--storage-snapshot-interval-sec=300"
• "--storage-snapshot-on-exit=true"
• "--storage-snapshot-retention-count=3"
• "--storage-wal-enabled=true"
• "--storage-wal-file-flush-every-n-tx=100000"
• "--storage-wal-file-size-kib=20480"

Hi @ValeriiaNesterova, thanks for opening the issue. I will address this ASAP.

I noticed the similar question on Stack overflow: https://stackoverflow.com/questions/77599471/memgraph-platform-doesnt-display-logs

I guess you open both, if that is so, let's handle all communication here and post an answer, once we are sure what the issue is.

@antejavor Hi, yes, it was my question as well. Sure, let's handle communication here

Hi @ValeriiaNesterova, can you share a bit of context on where the UI from which you are connecting is located? Second question is why are you running two Memgraph instances in two pods?

Do you have Memgraph Lab installed on your machine as a standalone application?

root@memgraph-lab-0:/# nc -vz memgraph 7444 This is expected to work from the pod, Memgraph will stream by default on 7444, if you are connecting from the outside, probably port is probably not reachable.

[ValeriiaNesterova]

@antejavor Hi. I don't have Memgraph Lab as a standalone application. I am using Kubernetes only.
I have 2 pods: one for memgraph itself (memgraph/memgraph) and second for UI access (memgraph-platform docker image).
I am opening UI using ingress from Kubernetes, ingress is listening to "memgraph-platform".

[antejavor]

Here is a bit of context that is important:

Memgraph-platform contains MemgraphDB (same as memgraph/memgraph), Mage, and Memgraph LAB. The platform exists to have all software packed into a single container that is easy to get started and use.

That means you do not need two pods.

Memgraph LAB is intended to be used from a local machine as a standalone software. You can download it here. So you deploy your Memgraph DB in a single pod and then connect to a pod from your local Lab.

Memgraph Lab is still not intended to be deployed as an application in the standalone pod. We will make LAB to be deployable as a standalone app, container at some point.

After I have shared to context, do you have a need for a Lab to be deployed when you can have your local version? Can you elaborate on that part, and how you intended to use Memgraph?

[ValeriiaNesterova]

@antejavor Thank you very much for your explanation. It's needed for developers. They should open the URL of Memgraph and then add modules, execute queries, etc. The Memgraph itself should be run on Kubernetes.

I will try to leave only one pod (with memgraph-platform) and then download Memgraph LAB and connect via it to the Memgraph platform running on Kubernetes. And then I will check if logs will be available.

@ValeriiaNesterova, you can also run only Memgraph Lab from the Memgraph platform image -> https://github.com/memgraph/memgraph-platform#lab-only

[antejavor]

@ValeriiaNesterova, one more piece of information since you will deploy memgraph/memgraph-platform: the Memgraph platform contains the LAB, and by default, the UI will be started on port 3000 inside the pod.

If you do not disable anything (the link that @katarinasupe shared above) and if you expose that port outside, you should be able to connect to the same UI from your browser, but I would recommend downloading LAB, then everyone in the organization has private LAB with queries and proper setups.

Anyway, keep us in the loop if you need extra help, or get stuck 😃

@antejavor @katarinasupe Thank you, guys. I will let you know in case of any updates from my side.
