Problems to modify metrics

[mcebey1891]

Hello,

I am running the hep-grafana-loki docker version of Homer7.

I need to make some modifications to the Heplify-server metrics so I downloaded the source from: https://github.com/sipcapture/heplify-server and without modifying it, I compiled it.

The problem is that by changing the heplify-server executable by the compiled one and restarting the container, it is continually restarting.

On the console I get messages that contains: invalid input syntax for type json

Is there any incompatibility between the two versions of the server? Should I delete the databases and start them from scratch when I change the executable?

Thanks

If the container is restarting there are probably more logs. Make sure you capture those to understand why its failing and/or share them here, raising the level to debug if needed.

No particular reason why this approach should fail so this might be configuration related.

Second thought - make sure the Loki container actually works - there were changed to the configuration format and location recently. Or perhaps try the 7.7 branch variants which are actively tested.

Without raising the debug level, the log throws a lot of this:

2019/11/05 16:58:23.022921 postgres.go:287: ERR pq: invalid input syntax for type json
2019/11/05 16:58:23.023213 postgres.go:295: ERR pq: Could not complete operation in a failed transaction
2019/11/05 16:58:23.095937 postgres.go:287: ERR pq: invalid input syntax for type json
2019/11/05 16:58:23.096189 postgres.go:295: ERR pq: Could not complete operation in a failed transaction

2019/11/05 16:58:26.870652 postgres.go:295: ERR pq: Could not complete operation in a failed transaction

2019/11/05 16:58:26.942431 postgres.go:295: ERR pq: Could not complete operation in a failed transaction

Now I will change to the version compiled by me and I will test again.

[mcebey1891]

I can't find anything useful in the log with debug level at "debug". Maybe i'm not seeing the right log (docker logs -f heplify-server)
I will make a test scenario and I will test with the 7.7 branch.

Cannot reproduce this. Just built a release and its working fine in a container.
Perhaps @negbie could suggest what this might relate to. Are you feeding it HEP from HEPlify or any other platform?

[negbie]

@lmangani can't reproduce. Just build latest heplify-server master and used a pg only docker container.

[mcebey1891]

The procedure I use is as follows:

1.- I build the latest heplify-server master.

2.- I replaced the file in the corresponding docker:
docker cp /home/mcebey/heplify-server heplify-server:/root

3.- I corrected the permissions:
docker exec -ti heplify-server sh -c "chown root:root heplify-server"

4.- Restart the container:
docker restart heplify-server

I try to stop all the containers and start again but I have the same result.

I'm a beginner with docker, what does pg only docker mean?

[negbie]

PG only means a docker container only for postgres. For example this one:
