Several PostgreSQL servers are connected to the monitoring. The agent configuration is the same everywhere. On some servers, the monitoring shows that there is no QAN information.

How can I understand why QAN is not returning queries? All host metrics are present, but there are no queries.

Agent settings:  
`pg_stat_monitor.pgsm_bucket_time: 60`  
`pg_stat_monitor.pgsm_enable_overflow: true`  
`pg_stat_monitor.pgsm_enable_pgsm_query_id: false`  
`pg_stat_monitor.pgsm_enable_query_plan: true`  
`pg_stat_monitor.pgsm_histogram_max: 30000`  
`pg_stat_monitor.pgsm_histogram_min: 50`  
`pg_stat_monitor.pgsm_max: 512`  
`pg_stat_monitor.pgsm_max_buckets: 20`  
`pg_stat_monitor.pgsm_normalized_query: true`  
`pg_stat_monitor.pgsm_query_shared_buffer: 384`  
`pg_stat_monitor.pgsm_track_application_names: false`  
`pg_stat_monitor.pgsm_track_planning: false`

hi @ANDiv1976 ,

I would start by checking the PMM client-side status and logs from the affected nodes:

```auto
pmm-admin list
journalctl -u pmm-agent

```

or to get them in a zip file:

```auto
pmm-admin summary

```

Also check you are indeed generating query data, and that it’s current:

```auto
postgres#= SELECT count(*) from pg_stat_monitor;

```

```auto
postgres#= SELECT * from pg_stat_monitor LIMIT 5;

```

etc

hi, Augustin\_G!

The issue was with `pg_stat_monitor.pgsm_enable_pgsm_query_id: false`.  
After I changed it to `true`, queries appeared in QAN.
