Description:

When adding any queries into /usr/local/percona/pmm2/collectors/custom-queries/mysql/low-resolution/queries-mysqld.yml , they cannot be seen in the insights Advanced Data Exploration dashboard

Steps to Reproduce:

1. Create a configMap with data from: pmm-custom-queries/mysql/innodb-index-stats.yml at master · Percona-Lab/pmm-custom-queries · GitHub
2. Load the configmap into the PMM pod, when creating with helmfile:
   helm upgrade --install pmm percona/pmm -f values.yaml

3.Log into the shell of the pod, review the file:
cat /usr/local/percona/pmm2/collectors/custom-queries/mysql/low-resolution/queries-mysqld.yml

Version:

[percona/pmm-server:2.43.2]

Logs:

No errors or data indicating that the custom queries are loaded or not.

Expected Result:

Query should show up in dashboard ( advanced-data-exploration)

Actual Result:
