el-q-test's Issues

Monitoring intervals and monitoring target

I noticed, that default poll intervals are quite large. For example, the initialization of qdrant db from snapshot on my machine takes 1 minute, while the gap between CPU measurement is 2.5 minutes.

for memory and disk metrics it is a little bit better, but still far away from preferred. It would be interesting if we could see different loading stages on the graphs, and for this purpose we might want to collect metrics as wast as possible.

I tried to change timings in prometheus.yaml but it didn't result in any changes.

Permissions problem

When I try to run docker-compose with provided instructions, 3 out of 5 containers refuse to start during the file permission problems:

GF_PATHS_DATA='/var/lib/grafana' is not writable.
You may have issues with file permissions, more information here: http://docs.grafana.org/installation/docker/#migrate-to-v51-or-later
mkdir: can't create directory '/var/lib/grafana/plugins': Permission denied

I was able to temporary fix the first two problems by commenting out

./grafana/grafana_storage:/var/lib/grafana
./prometheus/prometheus_data:/prometheus

I assume it is only needed for the persistence between restarts.

But I don't yet know how to fix cadvisor problem
